Eth 2.0 vs Polkadot and other musings by a fundamental investor
Spent about two hours on this post and I decided it would help the community if I made it more visible. Comment was made as a response to this
I’m trying to avoid falling into a maximalist mindset over time. This isn’t a 100% ETH question, but I’m trying to stay educated about emerging tech. Can someone help me see the downsides of diversifying into DOTs? I know Polkadot is more centralized, VC backed, and generally against our ethos here. On chain governance might introduce some unknown risks. What else am I missing? I see a bunch of posts about how Ethereum and Polkadot can thrive together, but are they not both L1 competitors?
What else am I missing?
The upsides. Most of the guys responding to you here are full Eth maxis who drank the Parity is bad koolaid. They are married to their investment and basically emotional / tribal in an area where you should have a cool head. Sure, you might get more upvotes on Reddit if you do and say what the crowd wants, but do you want upvotes and fleeting validation or do you want returns on your investment? Do you want to be these guys or do you want to be the shareholder making bank off of those guys? Disclaimer: I'm both an Eth whale and a Dot whale, and have been in crypto for close to a decade now. I originally bought ether sub $10 after researching it for at least a thousand hours. Rode to $1500 and down to $60. Iron hands - my intent has always been to reconsider my Eth position after proof of stake is out. I invested in the 2017 Dot public sale with the plan of flipping profits back to Eth but keeping Dots looks like the right short and long term play now. I am not a trader, I just take a deep tech dive every couple of years and invest in fundamentals. Now as for your concerns:
I know Polkadot is more centralized
The sad truth is that the market doesn't really care about this. At all. There is no real statistic to show at what point a coin is "decentralized" or "too centralized". For example, bitcoin has been completely taken over by Chinese mining farms for about five years now. Last I checked, they control above 85% of the hashing power, they just spread it among different mining pools to make it look decentralized. They have had the ability to fake or block transactions for all this time but it has never been in their best interest to do so: messing with bitcoin in that way would crash its price, therefore their bitcoin holdings, their mining equipment, and their company stock (some of them worth billions) would evaporate. So they won't do it due to economics, but not because they can't. That is the major point I want to get across; originally Bitcoin couldn't be messed with because it was decentralized, but now Bitcoin is centralized but it's still not messed with due to economics. It is basically ChinaCoin at this point, but the market doesn't care, and it still enjoys over 50% of the total crypto market cap. So how does this relate to Polkadot? Well fortunately most chains - Ethereum included - are working towards proof of stake. This is obviously better for the environment, but it also has a massive benefit for token holders. If a hostile party wanted to take over a proof of stake chain they'd have to buy up a massive share of the network. The moment they force through a malicious transaction a proof of stake blockchain has the option to fork them off. It would be messy for a few days, but by the end of the week the hostile party would have a large amount of now worthless tokens, and the proof of stake community would have moved on to a version of the blockchain where the hostile party's tokens have been slashed to zero. So not only does the market not care about centralization (Bitcoin example), but proof of stake makes token holders even safer. That being said, Polkadot's "centralization" is not that far off to Ethereum. The Web3 foundation kept 30% of the Dots while the Ethereum Foundation kept 17%. There are whales in Polkadot but Ethereum has them too - 40% of all genesis Ether went to 100 wallets, and many suspect that the original Ethereum ICO was sybiled to make it look more popular and decentralized than it really was. But you don't really care about that do you? Neither do I. Whales are a fact of life.
VCs are part of the crypto game now. There is no way to get rid of them, and there is no real reason why you should want to get rid of them. They put their capital at risk (same as you and me) and seek returns on their investment (same as you and me). They are both in Polkadot and Ethereum, and have been for years now. I have no issue with them as long as they don't play around with insider information, but that is another topic. To be honest, I would be worried if VCs did not endorse chains I'm researching, but maybe that's because my investing style isn't chasing hype and buying SUSHI style tokens from anonymous (at the time) developers. That's just playing hot potato. But hey, some people are good at that. As to the amount of wallets that participated in the Polkadot ICO: a little known fact is that more individual wallets participated in Polkadot's ICO than Ethereum's, even though Polkadot never marketed their ICO rounds due to regulatory reasons.
generally against our ethos here
Kool aid. Some guy that works(ed?) at Parity (who employs what, 200+ people?) correctly said that Ethereum is losing its tech lead and that offended the Ethereum hivemind. Oh no. So controversial. I'm so personally hurt by that. Some guy that has been working for free on Ethereum basically forever correctly said that Polkadot is taking the blockchain tech crown. Do we A) Reflect on why he said that? or B) Rally the mob to chase him off?
Also Parity locked their funds (and about 500+ other wallets not owned by them) and proposed a solution to recover them. When the community voted no they backed off and did not fork the chain, even if they had the influence to do so. For some reason this subreddit hates them for that, even if Parity did the 100% moral thing to do. Remember, 500+ other teams or people had their funds locked, so Parity was morally bound to try its best to recover them. Its just lame drama to be honest. Nothing to do with ethos, everything to do with emotional tribalism. Now for the missing upsides (I'll also respond to random fragments scattered in the thread):
This isn’t a 100% ETH question, but I’m trying to stay educated about emerging tech.
A good quick intro to Eth's tech vs Polkadot's tech can be found on this thread, especially this reply. That thread is basically mandatory reading if you care about your investment. Eth 2.0's features will not really kick in for end users until about 2023. That means every dapp (except DeFI, where the fees make sense due to returns and is leading the fee market) who built on Eth's layer 1 are dead for three years. Remember the trading card games... Gods Unchained? How many players do you think are going to buy and sell cards when the transaction fee is worth more than the cards? All that development is now practically worthless until it can migrate to its own shard. This story repeats for hundreds of other dapp teams who's projects are now priced out for three years. So now they either have to migrate to a one of the many unpopulated L2 options (which have their own list of problems and risks, but that's another topic) or they look for another platform, preferably one interoperable with Ethereum. Hence Polkadot's massive growth in developer activity. If you check out https://polkaproject.com/ you'll see 205 projects listed at the time of this post. About a week ago they had 202 listed. That means about one team migrated from another tech stack to build on Polkadot every two days, and trust me, many more will come in when parachains are finally activated, and it will be a complete no brainer when Polkadot 2.0 is released. Another huge upside for Polkadot is the Initial Parachain Offerings. Polkadot's version of ICOs. The biggest difference is that you can vote for parachains using your Dots to bind them to the relay chain, and you get some of the parachain's tokens in exchange. After a certain amount of time you get your Dots back. The tokenomics here are impressive: Dots are locked (reduced supply) instead of sold (sell pressure) and you still earn your staking rewards. There's no risk of scammers running away with your Ether and the governance mechanism allows for the community to defund incompetent devs who did not deliver what was promised.
Wouldn’t an ETH shard on Polkadot gain a bunch of scaling benefits that we won’t see natively for a couple years?
Yes. That is correct. Both Edgeware and Moonbeam are EVM compatible. And if the original dapp teams don't migrate their projects someone else will fork them, exactly like SUSHI did to Uniswap, and how Acala is doing to MakerDao.
Although realistically Ethereum has a 5 yr headstart and devs haven't slowed down at all
Just because it's "EVM Compatible" doesn't mean you can just plug Ethereum into Polkadot or vica versa, it just means they both understand Ethereum bytecode and you can potentially copy/paste contracts from Ethereum to Polkadot, but you'd still need to add a "bridge" between the 2 chains, so it adds additional complexity and extra steps compared to using any of the existing L2 scaling solutions
That only applies of you are thinking from an Eth maximalist perspective. But if you think from Polkadot's side, why would you need to use the bridge back to Ethereum at all? Everything will be seamless, cheaper, and quicker once the ecosystem starts to flourish.
I see a bunch of posts about how Ethereum and Polkadot can thrive together, but are they not both L1 competitors?
They are competitors. Both have their strategies, and both have their strengths (tech vs time on the market) but they are clearly competing in my eyes. Which is a good thing, Apple and Samsung competing in the cell phone market just leads to more innovation for consumers. You can still invest in both if you like. Edit - link to post and the rest of the conversation: https://www.reddit.com/ethfinance/comments/iooew6/daily_general_discussion_september_8_2020/g4h5yyq/ Edit 2 - one day later PolkaProject count is 210. Devs are getting the hint :)
This is a follow-up on https://old.reddit.com/Bitcoin/comments/hqzp14/technical_the_path_to_taproot_activation/ Taproot! Everybody wants it!! But... you might ask yourself: sure, everybody else wants it, but why would I, sovereign Bitcoin HODLer, want it? Surely I can be better than everybody else because I swapped XXX fiat for Bitcoin unlike all those nocoiners? And it is important for you to know the reasons why you, o sovereign Bitcoiner, would want Taproot activated. After all, your nodes (or the nodes your wallets use, which if you are SPV, you hopefully can pester to your wallet vendoimplementor about) need to be upgraded in order for Taproot activation to actually succeed instead of becoming a hot sticky mess. First, let's consider some principles of Bitcoin.
You the HODLer should be the one who controls where your money goes. Your keys, your coins.
You the HODLer should be able to coordinate and make contracts with other people regarding your funds.
You the HODLer should be able to do the above without anyone watching over your shoulder and judging you.
I'm sure most of us here would agree that the above are very important principles of Bitcoin and that these are principles we would not be willing to remove. If anything, we would want those principles strengthened (especially the last one, financial privacy, which current Bitcoin is only sporadically strong with: you can get privacy, it just requires effort to do so). So, how does Taproot affect those principles?
Taproot and Your /Coins
Most HODLers probably HODL their coins in singlesig addresses. Sadly, switching to Taproot would do very little for you (it gives a mild discount at spend time, at the cost of a mild increase in fee at receive time (paid by whoever sends to you, so if it's a self-send from a P2PKH or bech32 address, you pay for this); mostly a wash). (technical details: a Taproot output is 1 version byte + 32 byte public key, while a P2WPKH (bech32 singlesig) output is 1 version byte + 20 byte public key hash, so the Taproot output spends 12 bytes more; spending from a P2WPKH requires revealing a 32-byte public key later, which is not needed with Taproot, and Taproot signatures are about 9 bytes smaller than P2WPKH signatures, but the 32 bytes plus 9 bytes is divided by 4 because of the witness discount, so it saves about 11 bytes; mostly a wash, it increases blockweight by about 1 virtual byte, 4 weight for each Taproot-output-input, compared to P2WPKH-output-input). However, as your HODLings grow in value, you might start wondering if multisignature k-of-n setups might be better for the security of your savings. And it is in multisignature that Taproot starts to give benefits! Taproot switches to using Schnorr signing scheme. Schnorr makes key aggregation -- constructing a single public key from multiple public keys -- almost as trivial as adding numbers together. "Almost" because it involves some fairly advanced math instead of simple boring number adding, but hey when was the last time you added up your grocery list prices by hand huh? With current P2SH and P2WSH multisignature schemes, if you have a 2-of-3 setup, then to spend, you need to provide two different signatures from two different public keys. With Taproot, you can create, using special moon math, a single public key that represents your 2-of-3 setup. Then you just put two of your devices together, have them communicate to each other (this can be done airgapped, in theory, by sending QR codes: the software to do this is not even being built yet, but that's because Taproot hasn't activated yet!), and they will make a single signature to authorize any spend from your 2-of-3 address. That's 73 witness bytes -- 18.25 virtual bytes -- of signatures you save! And if you decide that your current setup with 1-of-1 P2PKH / P2WPKH addresses is just fine as-is: well, that's the whole point of a softfork: backwards-compatibility; you can receive from Taproot users just fine, and once your wallet is updated for Taproot-sending support, you can send to Taproot users just fine as well! (P2WPKH and P2WSH -- SegWit v0 -- addresses start with bc1q; Taproot -- SegWit v1 --- addresses start with bc1p, in case you wanted to know the difference; in bech32 q is 0, p is 1) Now how about HODLers who keep all, or some, of their coins on custodial services? Well, any custodial service worth its salt would be doing at least 2-of-3, or probably something even bigger, like 11-of-15. So your custodial service, if it switched to using Taproot internally, could save a lot more (imagine an 11-of-15 getting reduced from 11 signatures to just 1!), which --- we can only hope! --- should translate to lower fees and better customer service from your custodial service! So I think we can say, very accurately, that the Bitcoin principle --- that YOU are in control of your money --- can only be helped by Taproot (if you are doing multisignature), and, because P2PKH and P2WPKH remain validly-usable addresses in a Taproot future, will not be harmed by Taproot. Its benefit to this principle might be small (it mostly only benefits multisignature users) but since it has no drawbacks with this (i.e. singlesig users can continue to use P2WPKH and P2PKH still) this is still a nice, tidy win! (even singlesig users get a minor benefit, in that multisig users will now reduce their blockchain space footprint, so that fees can be kept low for everybody; so for example even if you have your single set of private keys engraved on titanium plates sealed in an airtight box stored in a safe buried in a desert protected by angry nomads riding giant sandworms because you're the frickin' Kwisatz Haderach, you still gain some benefit from Taproot) And here's the important part: if P2PKH/P2WPKH is working perfectly fine with you and you decide to never use Taproot yourself, Taproot will not affect you detrimentally. First do no harm!
Taproot and Your Contracts
No one is an island, no one lives alone. Give and you shall receive. You know: by trading with other people, you can gain expertise in some obscure little necessity of the world (and greatly increase your productivity in that little field), and then trade the products of your expertise for necessities other people have created, all of you thereby gaining gains from trade. So, contracts, which are basically enforceable agreements that facilitate trading with people who you do not personally know and therefore might not trust. Let's start with a simple example. You want to buy some gewgaws from somebody. But you don't know them personally. The seller wants the money, you want their gewgaws, but because of the lack of trust (you don't know them!! what if they're scammers??) neither of you can benefit from gains from trade. However, suppose both of you know of some entity that both of you trust. That entity can act as a trusted escrow. The entity provides you security: this enables the trade, allowing both of you to get gains from trade. In Bitcoin-land, this can be implemented as a 2-of-3 multisignature. The three signatories in the multisgnature would be you, the gewgaw seller, and the escrow. You put the payment for the gewgaws into this 2-of-3 multisignature address. Now, suppose it turns out neither of you are scammers (whaaaat!). You receive the gewgaws just fine and you're willing to pay up for them. Then you and the gewgaw seller just sign a transaction --- you and the gewgaw seller are 2, sufficient to trigger the 2-of-3 --- that spends from the 2-of-3 address to a singlesig the gewgaw seller wants (or whatever address the gewgaw seller wants). But suppose some problem arises. The seller gave you gawgews instead of gewgaws. Or you decided to keep the gewgaws but not sign the transaction to release the funds to the seller. In either case, the escrow is notified, and if it can sign with you to refund the funds back to you (if the seller was a scammer) or it can sign with the seller to forward the funds to the seller (if you were a scammer). Taproot helps with this: like mentioned above, it allows multisignature setups to produce only one signature, reducing blockchain space usage, and thus making contracts --- which require multiple people, by definition, you don't make contracts with yourself --- is made cheaper (which we hope enables more of these setups to happen for more gains from trade for everyone, also, moon and lambos). (technology-wise, it's easier to make an n-of-n than a k-of-n, making a k-of-n would require a complex setup involving a long ritual with many communication rounds between the n participants, but an n-of-n can be done trivially with some moon math. You can, however, make what is effectively a 2-of-3 by using a three-branch SCRIPT: either 2-of-2 of you and seller, OR 2-of-2 of you and escrow, OR 2-of-2 of escrow and seller. Fortunately, Taproot adds a facility to embed a SCRIPT inside a public key, so you can have a 2-of-2 Taprooted address (between you and seller) with a SCRIPT branch that can instead be spent with 2-of-2 (you + escrow) OR 2-of-2 (seller + escrow), which implements the three-branched SCRIPT above. If neither of you are scammers (hopefully the common case) then you both sign using your keys and never have to contact the escrow, since you are just using the escrow public key without coordinating with them (because n-of-n is trivial but k-of-n requires setup with communication rounds), so in the "best case" where both of you are honest traders, you also get a privacy boost, in that the escrow never learns you have been trading on gewgaws, I mean ewww, gawgews are much better than gewgaws and therefore I now judge you for being a gewgaw enthusiast, you filthy gewgawer).
Taproot and Your Contracts, Part 2: Cryptographic Boogaloo
Now suppose you want to buy some data instead of things. For example, maybe you have some closed-source software in trial mode installed, and want to pay the developer for the full version. You want to pay for an activation code. This can be done, today, by using an HTLC. The developer tells you the hash of the activation code. You pay to an HTLC, paying out to the developer if it reveals the preimage (the activation code), or refunding the money back to you after a pre-agreed timeout. If the developer claims the funds, it has to reveal the preimage, which is the activation code, and you can now activate your software. If the developer does not claim the funds by the timeout, you get refunded. And you can do that, with HTLCs, today. Of course, HTLCs do have problems:
Privacy. Everyone scraping the Bitcoin blockchain can see any HTLCs, and preimages used to claim them.
This can be mitigated by using offchain techniques so HTLCs are never published onchain in the happy case. Lightning would probably in practice be the easiest way to do this offchain. Of course, there are practical limits to what you can pay on Lightning. If you are buying something expensive, then Lightning might not be practical. For example, the "software" you are activating is really the firmware of a car, and what you are buying is not the software really but the car itself (with the activation of the car firmware being equivalent to getting the car keys).
Even offchain techniques need an onchain escape hatch in case of unresponsiveness! This means that, if something bad happens during payment, the HTLC might end up being published onchain anyway, revealing the fact that some special contract occurred.
And an HTLC that is claimed with a preimage onchain will also publicly reveal the preimage onchain. If that preimage is really the activation key of a software than it can now be pirated. If that preimage is really the activation key for your newly-bought cryptographic car --- well, not your keys, not your car!
Trust requirement. You are trusting the developer that it gives you the hash of an actual valid activation key, without any way to validate that the activation key hidden by the hash is actually valid.
Fortunately, with Schnorr (which is enabled by Taproot), we can now use the Scriptless Script constuction by Andrew Poelstra. This Scriptless Script allows a new construction, the PTLC or Pointlocked Timelocked Contract. Instead of hashes and preimages, just replace "hash" with "point" and "preimage" with "scalar". Or as you might know them: "point" is really "public key" and "scalar" is really a "private key". What a PTLC does is that, given a particular public key, the pointlocked branch can be spent only if the spender reveals the private key of the given public key to you. Another nice thing with PTLCs is that they are deniable. What appears onchain is just a single 2-of-2 signature between you and the developemanufacturer. It's like a magic trick. This signature has no special watermarks, it's a perfectly normal signature (the pledge). However, from this signature, plus some datta given to you by the developemanufacturer (known as the adaptor signature) you can derive the private key of a particular public key you both agree on (the turn). Anyone scraping the blockchain will just see signatures that look just like every other signature, and as long as nobody manages to hack you and get a copy of the adaptor signature or the private key, they cannot get the private key behind the public key (point) that the pointlocked branch needs (the prestige). (Just to be clear, the public key you are getting the private key from, is distinct from the public key that the developemanufacturer will use for its funds. The activation key is different from the developer's onchain Bitcoin key, and it is the activation key whose private key you will be learning, not the developer's/manufacturer's onchain Bitcoin key). So:
Privacy: PTLCs are private even if done onchain. Nobody else can learn what the private key behind the public key is, except you who knows the adaptor signature that when combined with the complete onchain signature lets you know what the private key of the activation key is. Somebody scraping the blockchain will not learn the same information even if all PTLCs are done onchain!
Lightning is still useful for reducing onchain use, and will also get PTLCs soon after Taproot is activated, but even if something bad happens and a PTLC has to go onchain, it doesn't reveal anything!
Trust issues can be proven more easily with a public-private keypair than with a hash-preimage pair.
For example, the developer of the software you are buying could provide a signature signing a message saying "unlock access to the full version for 1 day". You can check if feeding this message and signature to the program will indeed unlock full-version access for 1 day. Then you can check if the signature is valid for the purported pubkey whose private key you will pay for. If so, you can now believe that getting the private key (by paying for it in a PTLC) would let you generate any number of "unlock access to the full version for 1 day" message+signatures, which is equivalent to getting full access to the software indefinitely.
For the car, the manufacturer can show that signing a message "start the engine" and feeding the signature to the car's fimrware will indeed start the engine, and maybe even let you have a small test drive. You can then check if the signature is valid for the purported pubkey whose privkey you will pay for. If so, you can now believe that gaining knowledge of the privkey will let you start the car engine at any time you want.
(pedantry: the signatures need to be unique else they could be replayed, this can be done with a challenge-response sequence for the car, where the car gathers entropy somehow (it's a car, it probably has a bunch of sensors nowadays so it can get entropy for free) and uses the gathered entropy to challenge you to sign a random number and only start if you are able to sign the random number; for the software, it could record previous signatures somewhere in the developer's cloud server and refuse to run if you try to replay a previously-seen signature.)
Taproot lets PTLCs exist onchain because they enable Schnorr, which is a requirement of PTLCs / Scriptless Script. (technology-wise, take note that Scriptless Script works only for the "pointlocked" branch of the contract; you need normal Script, or a pre-signed nLockTimed transaction, for the "timelocked" branch. Since Taproot can embed a script, you can have the Taproot pubkey be a 2-of-2 to implement the Scriptless Script "pointlocked" branch, then have a hidden script that lets you recover the funds with an OP_CHECKLOCKTIMEVERIFY after the timeout if the seller does not claim the funds.)
Now if you were really paying attention, you might have noticed this parenthetical:
(technical details: a Taproot output is 1 version byte + 32 byte public key, while a P2WPKH (bech32 singlesig) output is 1 version byte + 20 byte public key hash...)
So wait, Taproot uses raw 32-byte public keys, and not public key hashes? Isn't that more quantum-vulnerable?? Well, in theory yes. In practice, they probably are not. It's not that hashes can be broken by quantum computes --- they're still not. Instead, you have to look at how you spend from a P2WPKH/P2PKH pay-to-public-key-hash. When you spend from a P2PKH / P2WPKH, you have to reveal the public key. Then Bitcoin hashes it and checks if this matches with the public-key-hash, and only then actually validates the signature for that public key. So an unconfirmed transaction, floating in the mempools of nodes globally, will show, in plain sight for everyone to see, your public key. (public keys should be public, that's why they're called public keys, LOL) And if quantum computers are fast enough to be of concern, then they are probably fast enough that, in the several minutes to several hours from broadcast to confirmation, they have already cracked the public key that is openly broadcast with your transaction. The owner of the quantum computer can now replace your unconfirmed transaction with one that pays the funds to itself. Even if you did not opt-in RBF, miners are still incentivized to support RBF on RBF-disabled transactions. So the extra hash is not as significant a protection against quantum computers as you might think. Instead, the extra hash-and-compare needed is just extra validation effort. Further, if you have ever, in the past, spent from the address, then there exists already a transaction indelibly stored on the blockchain, openly displaying the public key from which quantum computers can derive the private key. So those are still vulnerable to quantum computers. For the most part, the cryptographers behind Taproot (and Bitcoin Core) are of the opinion that quantum computers capable of cracking Bitcoin pubkeys are unlikely to appear within a decade or two.
Current quantum computers can barely crack prime factorization problem for primes of 5 bits.
The 256-bit elliptic curve use by Bitcoin is, by my (possibly wrong) understanding, equivalent to 4096-bit primes, so you can see a pretty big gap between now (5 bit primes) and what is needed (4096 bit primes).
A lot of financial non-Bitcoin systems use the equivalent of 3072-bit primes or less, and are probably easier targets to crack than the equivalent-to-4096-bit-primes Bitcoin.
Quantum computers capable of cracking Bitcoin are still far off.
Pay-to-public-key-hash is not as protective as you might think.
We will probably see banks get cracked before Bitcoin, so the banking system is a useful canary-in-a-coal-mine to see whether we should panic about being quantum vulnerable.
For now, the homomorphic and linear properties of elliptic curve cryptography provide a lot of benefits --- particularly the linearity property is what enables Scriptless Script and simple multisignature (i.e. multisignatures that are just 1 signature onchain). So it might be a good idea to take advantage of them now while we are still fairly safe against quantum computers. It seems likely that quantum-safe signature schemes are nonlinear (thus losing these advantages).
If you are a singlesig HODL-only Bitcoin user, Taproot will not affect you positively or negatively. Importantly: Taproot does no harm!
If you use or intend to use multisig, Taproot will be a positive for you.
If you transact onchain regularly using typical P2PKH/P2WPKH addresses, you get a minor reduction in feerates since multisig users will likely switch to Taproot to get smaller tx sizes, freeing up blockspace for yours.
If you are using multiparticipant setups for special systems of trade, Taproot will be a positive for you.
Remember: Lightning channels are multipartiicpiant setups for special systems of lightning-fast offchain trades!
I Wanna Be The Taprooter!
So, do you want to help activate Taproot? Here's what you, mister sovereign Bitcoin HODLer, can do!
If you have developer experience especially in C, C++, or related languages
Review the Taproot code! There is one pull request in Bitcoin Core, and one in libsecp256k1. I deliberately am not putting links here, to avoid brigades of nontechnical but enthusiastic people leaving pointless reviews, but if you are qualified you know how to find them!
But I am not a cryptographeBitcoin Core contributomathematician/someone as awesome as Pieter Wuille
That's perfectly fine! The cryptographers have been over the code already and agree the math is right and the implementation is right. What is wanted is the dreary dreary dreary software engineering: are the comments comprehensive and understandable? no misspellings in the comments? variable names understandable? reasonable function naming convention? misleading coding style? off-by-one errors in loops? conditions not covered by tests? accidental mixups of variables with the same types? missing frees? read-before-init? better test coverage of suspicious-looking code? missing or mismatching header guards? portability issues? consistent coding style? you know, stuff any coder with a few years of experience in coding anything might be able to catch. With enough eyes all bugs are shallow!
If you are running a mining pool/mining operation/exchange/custodial service/SPV server
Be prepared to upgrade!
One of the typical issues with upgrading software is that subtle incompatibilities with your current custom programs tend to arise, disrupting operations and potentially losing income due to downtime. If so, consider moving to the two-node setup suggested by gmax, which is in the last section of my previous post. With this, you have an up-to-date "public" node and a fixed-version "private" node, with the public node protecting the private node from any invalid chainsplits or invalid transactions. Moving to this setup from a typical one-node setup should be smooth and should not disrupt operations (too much).
If you are running your own fullnode for fun or for your own wallet
Be prepared to upgrade! The more nodes validating the new rules (even if you are a non-mining node!), the safer every softfork will be!
If you are using an SPV wallet or custodial wallet/service (including hardware wallets using the software of the wallet provider)
Contact your wallet provider / SPV server and ask for a statement on whether they support Taproot, and whether they are prepared to upgrade for Taproot! Make it known to them that Taproot is something you want!
But I Hate Taproot!!
Raise your objections to Taproot now, or forever hold your peace! Maybe you can raise them here and some of the devs (probably nullc, he goes everywhere, even in rbtc!) might be able to see your objections! Or if your objections are very technical, head over to the appropriate pull request and object away!
Maybe you simply misunderstand something, and we can clarify it here!
Or maybe you do have a good objection, and we can make Taproot better by finding a solution for it!
I’m a commentator for a tournament of nightmares. I’m not sure the participants are willing.
You’d think being a psychiatric ward for 38 months would be enough to deter a guy from ever going back to a sport that involves watching human beings at the height of their physical prowess beat the living shit out of each other. Sometimes regulated, sometimes not. But, here I am, fresh outta the loony bin and reading the most unusual advertising slogan I’d ever laid eyes on; “The most terrifying tournament has come around once again! Conquer your fears in theNFC*…* literally.” This was the business card that accompanied my black envelope as it was handed to me on the discharge ward by a well dressed and gangly fella with an uncomfortable wide smile. He didn’t say much of anything, just that his name was “Watson” before bowing and holding up the envelope. “Heh, like the butler, right?” I said, taking the envelope from his plasticine hands. His smile ripples across his face and he nods slowly, his perfect hair unmoving in the strong wind before he turns on his heel and walks back to the black sedan. The cold air chilled my bones, and I pulled the medical bracelet from my wrist, grimacing at the marks underneath before following Watson to the Sedan and hauling my luggage into the trunk before setting off, not knowing how I came to even be there in the first place. I guess right now, that doesn’t really matter. What matters is where I am now and what I’m doing. "blood strewn across the canvas, frayed brain matter sailing across my head and splattering against the wall, a woman standing in a pool of blood as the deformed creature twitches on the ground" My name is Sal “Motormouth” Sabotta, I’m a sports commentator by trade. Be it combat sports, pro wrestling, death-matches or martial arts tournament, I’ve done it all. I won’t lie; Work can be hard to come by. I’ve spent months struggling for rent and resorting to less tried-and-true commentary methods in order to survive. That has, at times, involved trying my hand at some of the more underground competitions; unregulated fights, sick, illegal games bet on by people on the dark web and worse… Things I’m not going to detail here. Things I’m not proud to have taken a hefty pay-check for from greasy, sweaty fucks in Armani tracksuits and stinking of cheap booze and coke all the way up to well-dressed bitcoin farmers in their 20s who probably own child slaves. In short, I’m no stranger to the grim underworld or the secrecies with which they conduct their work. I see money and an easy way to make it with my voice; I don’t ask questions. So when I received an email the day of my discharge from the hospital and I’m told “you’ll receive a letter from Mr. Watson, take it and follow the instructions to the venue. Pay up front as agreed.”, I don’t question it. Especially when the note is personalised, and the doctor says my medical fees were covered. We drove past numerous landscapes, vistas and neighbourhoods before veering off into an industrial estate and entering an underground tunnel. Half a mile in, Watson stops the car and peers back, smiling. He directs a thumb to the service door in the side tunnel and rubs his neck, a scar running from ear to ear. Was he a former fighter? Gangster? I sighed and got out, still in my medical gown and hauling ass to the door. It opened before I could reach out and a tall, muscular woman in her late 30s greeted me with a smile. She was imposing, powerful in her gait, a black eyepatch with several seals adorning the sides accompanying a thick scar down her face did nothing to stop her beauty. She wore a tank top with a black cloak with white fur on the tops and sleeves, a thick black chain clasp around the neck. I won’t lie; she looked badass. Terrifying, but badass. “‘Bout time ya showed up, Sabotta!” She grinned and put a cinderblock of a hand on my shoulder. I’m 5’10 and 180lbs, but she made me feel like a child in front of her. The power emanating from her fist was unbelievable. “C’mon, the trial match is starting and I don’t want no tourney without a broken in commentator! You gotta know the ropes of this place!” “You know your driver was standing right outside when I was discharged, right? Couldn’t think to give me an extra day or two to freshen up?” I frowned. This wasn’t normal protocol, even for back-alley promotions like this. She just laughed at me and slapped my shoulder. “The tournament waits for nobody, Sal. Times a-wasting.” The hallway is dimly lit and the sounds of a ruckus above us are as impossible to ignore as the sounds of thudding, screaming and snapping. As we pass several doors with one-way mirrors on the front panes, I hear sounds I could have never placed in the animal kingdom or otherwise; gurgles, clicks, grunts and even otherworldly whispers. “What the fuck is that? You guys doing animal fights down here? I mean I called a monkey fight once, but it’s not exactly… pleasant.” I shuddered, thinking of the violence chimpanzees can inflict on one another, let alone humans. She never stopped walking or staring directly ahead when she responded.“Those ain’t animals. Not by a long shot.” Before I can probe further, I’m hurried into a changing room and practically swept off my feet by her strength. I turn back and she’s already poking her head out the door. “You’ve got 5 minutes, get your shit and head up the left stairs, Watson will guide you.” She grinned, and I saw gold filings in her teeth that glinted as much as her bedazzled eye patch. “Ya came highly recommended… I expect good things!” I do as instructed and within 5 minutes I’m back in my commentary clothes; an open buttoned Hawaiian shirt with my old Hotel Inertia shirt underneath, skinny black jeans and shimmering black shoes. I found some old slick gorilla powder in my hair and dusted it up, opting for the dishevelled look as I knew I’d be sweating by the end of the ordeal. “You shouldn’t bother putting in so much effort, y’know. They’re not gonna care how good you look, only how well you talk.” Standing in the doorway was a woman in her 40s, dark-skinned and hair clad in meticulous dreadlocks, tied back into a large bun with a pair draped down the sides of her head. She held a thick book in one hand and pocketed a serrated blade in the other before motioning to me. “We’ll have to do the pleasantries on the way, the match is starting and you don’t wanna miss that. The commissioner isn’t the type you want to upset. Especially when you’re not here by choice.” I looked for a moment, dumbfounded. “I’m here because I was invited, already got my pay from the woman who let me in.” I shrugged, pocketing the envelope and getting my equipment from the suitcase. The woman gave a sad smile and shook her head. “Of course you’d think that. She likes it that way. Bet she didn’t introduce herself either, did she? C’mon.” I follow her down and after a few minutes we come to a fork in the hallway, an elevator system to our right and a stairway to the left. Dutifully, Watson stood patiently, still grinning and motioning us to go up. Once we’re situated in our booth upstairs, I set my equipment up and look down at the table, expecting a slew of papers and fighter information in front of me. I look to the woman to ask, but she doesn’t break her stare in the darkness, looking down at the arena floor some 100ft below us.“You won’t need that. Not for this match.” The lights flicker on and the enormity of this venue reveals itself to me. It’s a structure of imposing steel, dried blood, claw marks and other unknown substances that littered the 40ft wide circular pit the fighters contested in, a black lift on either side from the fighters corners that I can only assume ascended up from their locker room area. Around them were chain-link fences that rose up to the audience stands above, situating around 300 people across all four sides. At the very top sat our booth, the commissioner’s office directly opposite, the judges booth to our right and the fight analysts/medical area to our left. Standing in the centre with a spotlight over them was the commissioner, microphone in hand and an energy that was almost palpable. “Ladies, Gentlemen and Freaks of all kinds out there in the universe. I welcome you once more to the annual Nightmare Fighting Championship Tournament! It’s been a long year, but we have new blood to pit against our resident night terrors and some fresh fears to feast on the fortuitous soul that frolics into their den. As always, our contestants will be fighting for their freedom, a chance to get their wish or to fight for the ultimate prize.” The crowd cheers and the majority are hidden behind thick plexiglass and lighting, but I can see some have Karate Gi’s, weapons in hand and others with demon masks as they whoop and holler. The clientele here were, at least in my estimation, experienced. But I was feeling a lump in my throat at that one phrase The Commissioner so surreptitiously added in without issue; “As always, our contestants will befightingfor theirfreedom*”* I leaned to the woman next to me and as if she knew what I was going to ask; she put a finger up and shook her head. Eyes awash with fear and a grimness I had only seen on that of trainers who knew their fighter was not ready for the bout ahead. She pointed the finger down to my machine, then to the pit. Turning it on, I looked down as the commissioner began to talk, readying myself to commentate on whatever weirdos came up to battle. “But before we get to that, we have an exciting exhibition match for our loyal supporters who bankroll this event every year. Without you elite few, we could not do this. You are the pound for pound goats of support! Now, without further ado; let’s get this show on the road!”The rest of the lights clicked on and spun around the venue as they raised the profile of the bout, the elevators both whirring into action as the right one arose first. “In this corner, from the marionettes shop and accompanied by his Bunraku doll “Mr. Stares”, it’s the man who pulls the strings… THE PUPPET MAN!” Out steps a tall, thin Japanese man in full clown makeup. His head shaven save for two ridiculous strands of hair stretched out and fluffed up to their limits, like red antennae. His eyebrows large m’s that practically cover his forehead, the nose a completely vacant slot with a black hole drawn in and the mouth… the fucking mouth was nailed shut. Literally. Sharp rusted nails had been hammered down through the lips with such force that they’d bent. A sickening crimson red face-paint stretched across the entire bottom half of his face, making it seem far larger by comparison. He carefully held a small bundle underneath a sheet and bowed deeply to the audience before standing at his designated spot. “In the other corner, from the streets of god knows where and the womb of someone who misses him… "Hulked Up" Michael O’Donnell!” I watched with wide eyes and a stomach threatening to evacuate its contents at any moment as the smoke cleared and a boy no older than 17 rushed out, beating his chest and screaming to the crowd as if he was the Incredible Hulk. I don’t know if they drugged the poor kid, but he clearly had no idea where he was. “There are no rules, no referees and judges only exist in case of a draw or unclear victory. Our commentary team will take over and we wish you a phenomenal match.” She drools a little before she speaks again, looking up at me and winking. “Let’s make this a violent one.” She snaps her fingers and leaps for the fence, climbing up with ungodly ease before sitting on her makeshift chair in her office. I have no idea what I’m seeing but every cell in my body is urging me to run; I feel my knees tense and my frame rise ever so slightly before the woman next to me puts her hand on my thigh, pushing me down with great force. “You have a job to do, so do I. Trust me, you think you can leave but if you get out of this chair, not only will YOUR life end. Mine will too.” She unsheathes the serrated blade and looks at me with pity. “We both have a part to play here, so put the headset on and let’s do our job, no matter how hard it is.” Hands shaking, I pick up the headset and connect it to the portable recorder and take a breath. “I… I need your name. What is it you do?” I stutter, trying to calm myself. She hands me a bottle of water as the surrounding lights dim and the spotlight focuses on the spectacle below. “I’m Madame Nelle Lockwood, cryptid hunter and your co-host to guide you through tonight. Good to meet you, Sal.” - NFC EXHIBITION MATCH: "Hulked Up" Michael O’Donnell vs The Puppet Man w/ Mr. Stares “Welcome fight fans from around the world, god knows how you’re listening to this or WHY, but here we are. I’m your host Sal “MotorMouth” Sabotta, wishing this was all a bad dream. Joining me this evening is our cryptid specialist and all round badass Madame Nelle Lockwood. How are you doing, Nelle?” She looks at me with a bewildered look on her face before blinking and coming to her senses. “Uhh… good! All things considered… boy, you really have a professional knack for this, huh? I can see why Commissioner Alduin brought you in." “Ahh, yes. That’s right, folks! NFC Commissioner Alduin invited me here personally and our exhibition match proves to be… challenging. Let’s check in on the action below.” I look down and see The Puppet Man sat down and gesturing to the figure under the sheet, like he’s got a negotiation going on. The boy, undeterred and furious, rushes towards him and takes his back, slapping his head and even pulling on his hair with extreme prejudice. “Well take a gander at that, that kid has absolutely NO fear. When I was his age, I would have stayed FAR the fuck away from a nightmare spectre like that. But hell, this is all part of the show, right? Hope they’re paying that poor guy down there a sizeable sum to throw a fight to a child. What do you think, Nelle; is this the weirdest make-a-wish fulfilment task or what?” I look over to her, hoping she’d indulge me and that I could believe this was just going to end with a pissed off actor storming away when the child hit him too hard. But Nelle was scanning her now open book and looking for information on dolls. “He’s talking to his doll because it’s desperate to be let loose. He’s trying to bargain with it to spare him. This is the nature of the puppeteer and his master.” She pushes the book to the centre of the table and shows me a faded illustration of a pristine Bunraku doll; a kind of meticulously crafted Japanese take on the ventriloquist doll. The limbs are thinner and the face is more minimalist, but still no more frightening. “They usually have a symbiotic relationship, but it seems this one obeys the doll and will not want to face more punishment.” “What do you mean more punishment?” I ask, looking back down at the feverish puppet man as he tries signing frantically under the sheet, even putting his head under as the kid bites his arm and kicks him, screeching. “The nails, Sal. Those aren’t to silence him, they’re to punish him.” The rest happened in slow motion; the sheet fell down. The puppet man stood up and walked to his side of the fighters corner, facing the elevator and placing his face into his forearms as he shook. The boy followed to keep attacking, but with one swift kick to the midsection, the boy was propelled back to the centre of the pit where the doll sat. If there was a human face, I didn’t see it. Instead, I was staring down at a small wood carved spider, the head sporting black geisha hair and the makeup still present, but rows of sharpened black teeth protruded from the clicking mouth and two larger eyes jutted out from the base of the skull, smaller ones dotted closely around it. It was like seeing a puppet ogre spider. “Looks like The Puppet Man has let Mr. Stares out to say hi and I can certainly see why he was under that sheet, this one isn’t pretty folks! The face doth fit the name. The question is, what’s he doing to do ne- “I didn’t need to finish the question. My hands shook, and the world spun around me as this creature crawled towards the still wheezing boy with ungodly speed and perched itself expertly beside him. I don’t know if it was my eyes or the distance from where I sat, but this was NOT a small puppet. He was easily half of the boy’s height and that became more unnerving when he reared up on his back legs, the head clicking up and the raspy voice hissing out like a gas leak in a building. “Hey, hey, kid! Wanna make a deal?” The kid rubbed his eyes, seemingly realising where he was as he calmed down and an air of utter confusion around him. “If you let me be your new master and you promise to take care of me, I’ll let you go!” His head spun around and the jaw clicked ferociously as he giggled, extending out a clawed paw. “Whaddya say?” The boy, still confused, slowly reached out his hand and the moment immediately reminded me of a slew of nature shows I’d seen as a kid; where a predator waits until the prey is lulled before striking. I felt the chill up my spine as he extended his hand and grabbed Mr. Stares. In that moment, he leapt up the arm and bore his way into the boy’s mouth, down his throat and shredded his flesh. The sound was so horrifying, so visceral that it outshines any backyard stabbing, joint snap or broken nose. The boy didn’t even have time to scream, he simply looked up with tear-stained eyes as the puppet disappeared. Then he started walking without him realising. He looked down at his limbs, terrified, looked over at The Puppet Master, who still had his head to the elevator and pleaded with someone, anyone to help him. I looked to Nelle who refused to take her eyes away, studying the battle in an almost morbid scientific curiosity, detached entirely from the scenario. I couldn’t fathom how she did it, how she ignored this boy begging us to get him out of there. I wanted to. Every instinct in me as a fight fan and a decent human was to scream “STOP THE FIGHT!”. But clearly, when my own life is at risk and money is involved... I am not a decent human. Instead, with bile in my throat and a sweating forehead, I did my job. “M-My goodness! The P-uppet, I mean, “Mr. Stares” has BECAME the puppet master, surely the fight will be over with our young competitor incapacitated? What does our commissioner have to say about this?” She stared at me, her one eye gleaming and her face elated with the violence. “It ain’t over yet, church boy. We haven’t even seen the finale, have we Puppet Master?!” She laughs and slaps her knee, the puppet master sobbing as he sinks to the floor and she continues. “He ain’t done feeding, not yet.” The way she said that word “feeding” nearly made me lose what food I had in me. That was a young man, somebody's baby boy… “What does she mean by that, Nelle? What is the strategy to victory here?” Nelle looked down at her book and traced her finger across a passage before wiping her forehead and pushing the locks aside. If her composure wasn’t breaking yet, it would do soon. “This kind of parasitic doll feasts on its prey and targets non-essential organs first, controls the host with the neurotoxin in its tail and then, when it’s finally content, it gives the brain a second injection.” “What happens then?” I asked, my own professionalism hanging on by a fucking thread at this point. She shook her head and pinched the bridge of her nose.“I guess you’ll see in a moment, I sure as hell don’t want to. Not again.” Before I can prompt her further, the boy lets out an ear-piercing shriek and falls to his knees, gripping at his head before it turned red, then purple and finally an ugly shade of puce before… The sound of a watermelon hitting the ground from a great height is the best comparison you’re going to get without making me want to rush to the toilet to puke for a third time. But that’s what happened. His head burst and chunks of his skull, flesh and brain matter sprayed the pit and the walls, some hitting my desk and making me audibly shriek, much to the commissioner's delight. “HA! You didn’t run! I like you, Sal. You pass for the tournament!” She hauls her body up and slams down to the pit, applauding as the microphone descends from the heavens. “And your winner; The Puppet Man and Mr. Stares!” The crowd erupts with applause as the weeping puppet man pulls the blood-soaked puppet out, places him under the sheet and silently begins to walk back to the elevator while attendees clear up the boy’s corpse. “What… what the fuck IS this place?” I ask Nelle, pausing my recording. “This is where nightmares are kept and set upon mostly unwilling competitors for the world’s amusement. You HAVE done dark web fights before, right? Mafia snitches being put into lions pits, bum fights, addicts fighting women to score… this can’t be THAT unusual to you?” I stared at her incredulously. Was that even a question? “I did the dark web ONCE and it damn sure didn’t involve monsters!” She scoffs and closes her book, stretching before looking at me with contempt. “Oh, it did. Just not the ones you hear about in fairytales. Good luck with the selection process. I’ll be back for the opening round. Don’t try to run, they’ll devour us both in minutes, if you think this is the pinnacle of what lurks beneath this club, you're in for a rough night.” She sauntered off, leaving me deflated, sickened and terrified. Unable to leave and frustrated to the point of tears that I couldn’t express that concoction of emotions, I did what I always do; I regressed and pressed “record” on the device as Commissioner Alduin continued. At that moment, however, I was deaf to it all. The gravity of the situation had fully enveloped me… They weren’t kidding about the unwilling participants, I just didn’t realise I would be one of them.On every side of me sits men and women with a desire for violence that goes beyond the norm, beyond the sane and beyond the boundaries of humanity.Below me are an untold number of creatures rattling their cages and howling for blood. Across from me is a woman so powerful she could crush my skull beneath her boot with the utmost ease if it so amused her. That invitation was nothing more than my own ransom note in pretty colours and flattering platitudes. I was in a tournament housing nightmares incarnate. And it would only get more violent from here on out. - The opening round was a blood bath.
Hello Fellow Redditors, I am going to list some of my income sources. I will try to give as much information as I can. Some details about me:I am u/abhiearns, I am currently studying. I want to create some sort of extra income sources. I have been trying to use beermoney as well as other passive income communities like passive_income, passiveincome to find some sites and sources that can work for me. Enough with the details, Let start by listing some of my extra income sources. Active Earning: So, I will start with sites on which you have to work actively and devote some serious hours to earn some extra income. These are some beermoney sites (include survey sites, and other such sites):
QuickThoughts: This is one of my favorite survey site and I highly recommend it. It is one of the high paying survey sites. Each survey is between 5-30 min.

Qmee: This is also one of the good sites but over the years the earning potential has decreased. You can do surveys as well as they have an extensions which lets you earn while surfing search engines (Google and Bing). The surveys range between 2-30 mins and you can earn 0.1 - 2 dollars for each survey. The extensions lets you earn 0.01 - 0.1 dollars through suggestions but it is really infrequent. Best thing I like about them is that they don't have any minimum payment. It also lets you earn using Referrals of $1.

MinerGate: This is a site and software combination which provides you with mining software and pools. You just have to install the software and run mining. You can also use there mining pool if you want to use some other software. If you do start using this, I recommend mining Monero (XMR). They also have a referral program.
CashMagnet: This is an Android based app which lets you earn automatically. You just have to download some games from this app and run this and it will automatically run the apps. They also have a referral program.
Credit Card Cash backs: Yes, you can earn some kind of money using cashbacks from various credit card companies.

If you are a student I highly recommend using Discover Student Credit Card, you can get up to $50 just applying for it using this link.
Type: Credit Card Cash Back
Betterment (Robo Advisor): Betterment is one of the best robo advisor out there. If you just starting out and have no idea about investing, you can give this a show. They have different type of goals like retirement, general investing and other which help you to manage your money according to your own requirement. They charge 0.25% fees, but you get 1 year free when you create your account 1st time.
Acrons (Robo Advisor): Acrons is also a robo advisor but it is little different from betterment. Acorns lets you invest money by rounding your purchases like if you spend $5.75 at McDonalds it will invest $0.25 from your account. I know its really little and it adds up really fast and you won't feel much change in your lifestyle. It also gives you some cashback for purchases at certain vendors.
\** I am still trying other sites and apps. I will keep updating this post.* These are some of the sources I use to earn, I highly recommend these. I won't say you will become a millionaire using these but still its little more than you had yesterday.
Everyone and his grandma know what cryptocurrency mining is. Well, they may not indeed know what it actually is, in technical terms, but they have definitely heard the phrase as it is hard to miss the news about mining sucking in energy like a black hole gobbles up matter. On the other hand, staking, its little bro, has mostly been hiding in the shadows until recently. by StealthEX Today, with DeFi making breaking news across the cryptoverse, staking has become a new buzzword in the blockchain space and beyond, along with the fresh entries to the crypto asset investor’s vocabulary such as “yield farming”, “rug pull”, “total value locked”, and similar arcane stuff. If you are not scared off yet, then read on. Though we can’t promise you won’t be.
Cryptocurrency staking, little brother of crypto mining
There are two conceptually different approaches to achieving consensus in a distributed network, which comes down to transaction validation in the case of a cryptocurrency blockchain. You are most certainly aware of cryptocurrency mining, which is used with cryptocurrencies based on the Proof-of-Work (PoW) consensus algorithm such as Bitcoin and Ether (so far). Here miners compete against each other with their computational resources for finding the next block on the blockchain and getting a reward. Another approach, known as the Proof-of-Stake (PoS) consensus mechanism, is based not on the race among computational resources as is the case with PoW, but on the competition of balances, or stakes. In simple words, every holder of at least one stake, a minimally sufficient amount of crypto, can actively participate in creating blocks and thus also earn rewards under such network consensus model. This process came to be known as staking, and it can be loosely thought of as mining in the PoS environment. With that established, let’s now see why, after so many years of what comes pretty close to oblivion, it has turned into such a big thing.
Why has staking become so popular, all of a sudden?
The renewed popularity of staking came with the explosive expansion of decentralized finance, or DeFi for short. Essentially, staking is one of the ways to tap into the booming DeFi market, allowing users to earn staking rewards on a class of digital assets that DeFi provides easy access to. Technically, it is more correct to speak of DeFi staking as a new development of an old concept that enjoys its second coming today, or new birth if you please. So what’s the point? With old-school cryptocurrency staking, you would have to manually set up and run a validating node on a cryptocurrency network that uses a PoS consensus algo, having to keep in mind all the gory details of a specific protocol so as not to shoot yourself in the foot. This is where you should have already started to enjoy jitters if you were to take this avenu entirely on your own. Just think of it as having to run a Bitcoin mining rig for some pocket money. Put simply, DeFi staking frees you from all that hassle. At this point, let’s recall what decentralized finance is and what it strives to achieve. In broad terms, DeFi aims at offering the same products and services available today in the traditional financial world, but in a trutless and decentralized way. From this perspective, DeFi staking reseblems conventional banking where people put their money in savings accounts to earn interest. Indeed, you could try to lend out your shekels all by yourself, with varying degrees of success, but banks make it far more convenient and secure. The maturation of the DeFi space advanced the emergence of staking pools and Staking-as-a-Service (SaaS) providers that run nodes for PoS cryptocurrencies on your behalf, allowing you to stake your coins and receive staking rewards. In today’s world, interest rates on traditional savings accounts are ridiculous, while government spending, a handy euphemism for relentless money printing aka fiscal stimulus, is already translating into runaway inflation. Against this backdrop, it is easy to see why staking has been on the rise.
Okay, what are my investment options?
Now that we have gone through the basics of the state-of-the-art cryptocurrency staking, you may ask what are the options actually available for a common crypto enthusiast to earn from it? Many high-caliber exchanges like Binance or Bitfinex as well as online wallets such as Coinbase offer staking of PoS coins. In most cases, you don’t even need to do anything aside from simply holding your coins there to start receiving rewards as long as you are eligible and meet the requirements. This is called exchange staking. Further, there are platforms that specialize in staking digital assets. These are known as Staking-as-a-Service providers, while this form of staking is often referred to as soft staking. They enable even non-tech savvy customers to stake their PoS assets through a third party service, with all the technical stuff handled by the service provider. Most of these services are custodial, with the implication being that you no longer control your coins after you stake them. Figment Networks, MyContainer, Stake Capital are easily the most recognized among SaaS providers. However, while exchange staking and soft staking have everything to do with finance, they have little to nothing to do with the decentralized part of it, which is, for the record, the primary value proposition of the entire DeFi ecosystem. The point is, you have to deposit the stakable coins into your wallet with these services. And how can it then be considered decentralized? Nah, because DeFi is all about going trustless, no third parties, and, in a narrow sense, no staking that entails the transfer of private keys. This form of staking is called non-custodial, and it is of particular interest from the DeFi point of view. If you read our article about DeFi, you already know how it is possible, so we won’t dwell on this (if, on the off chance, you didn’t, it’s time to catch up). As DeFi continues to evolve, platforms that allow trustless staking with which you maintain full custody of your coins are set to emerge as well. The space is relatively new, with Staked being probably the first in the field. This type of staking allows you to remain in complete control of your funds, and it perfectly matches DeFi’s ethos, goals and ideals. Still, our story wouldn’t be complete if we didn’t mention utility tokens where staking may serve a whole range of purposes other than supporting the token network or obtaining passive income. For example, with platforms that deploy blockchain oracles such as Nexus Mutual, a decentralized insurance platform, staking tokens is necessary for encouraging correct reporting on certain events or reaching a consensus on a specific claim. In the case of Nexus Mutual, its membership token NXM is used by the token holders, the so-called assessors, for validating insurance claims. If they fail to assess claims correctly, their stakes are burned. Another example is Particl Marketplace, a decentralized eCommerce platform, which designed a standalone cryptocurrency dubbed PART. It can be used both as a cryptocurrency in its own right outside the marketplace and as a stakable utility token giving stakers voting rights facilitating the decentralized governance of the entire platform. Yet another example is the instant non-custodial cryptocurrency exchange service, ChangeNOW, that also recently came up with its stakable token, NOW Token, to be used as an internal currency and a means of earning passive income.
Nowadays, with most economies on pause or going downhill, staking has become a new avenue for generating passive income outside the traditional financial system. As DeFi continues to eat away at services previously being exclusively provided by conventional financial and banking sectors, we should expect more people to get involved in this activity along with more businesses dipping their toes into these uncharted waters. Achieving network consensus, establishing decentralized governance, and earning passive income are only three use cases for cryptocurrency staking. No matter how important they are, and they certainly are, there are many other uses along different dimensions that staking can be quite helpful and instrumental for. Again, we are mostly in uncharted waters here, and we can’t reliably say what the future holds for us. On the other hand, we can go and invent it. This should count as next.

Don't blindly follow a narrative, its bad for you and its bad for crypto in general
I mostly lurk around here but I see a pattern repeating over and over again here and in multiple communities so I have to post. I'm just posting this here because I appreciate the fact that this sub is a place of free speech and maybe something productive can come out from this post, while bitcoin is just fucking censorship, memes and moon/lambo posts. If you don't agree, write in the comments why, instead of downvoting. You don't have to upvote either, but when you downvote you are killing the opportunity to have discussion. If you downvote or comment that I'm wrong without providing any counterpoints you are no better than the BTC maxis you despise. In various communities I see a narrative being used to bring people in and making them follow something without thinking for themselves. In crypto I see this mostly in BTC vs BCH tribalistic arguments: - BTC community: "Everything that is not BTC is shitcoin." or more recently as stated by adam on twitter, "Everything that is not BTC is a ponzi scheme, even ETH.", "what is ETH supply?", and even that they are doing this for "altruistic" reasons, to "protect" the newcomers. Very convenient for them that they are protecting the newcomers by having them buy their bags - BCH community: "BTC maxis are dumb", "just increase block size and you will have truly p2p electronic cash", "It is just that simple, there are no trade offs", "if you don't agree with me you are a BTC maxi", "BCH is satoshi's vision for p2p electronic cash" It is not exclusive to crypto but also politics, and you see this over and over again on twitter and on reddit. My point is, that narratives are created so people don't have to think, they just choose a narrative that is easy to follow and makes sense for them, and stick with it. And people keep repeating these narratives to bring other people in, maybe by ignorance, because they truly believe it without questioning, or maybe by self interest, because they want to shill you their bags. Because this is BCH community, and because bitcoin is censored, so I can't post there about the problems in the BTC narrative (some of which are IMO correctly identified by BCH community), I will stick with the narrative I see in the BCH community. The culprit of this post was firstly this post by user u/scotty321"The BTC Paradox: “A 1 MB blocksize enables poor people to run their own node!” “Okay, then what?” “Poor people won’t be able to use the network!”". You will see many posts of this kind being made by u/Egon_1 also. Then you have also this comment in that thread by u/fuck_____________1 saying that people that want to run their own nodes are retarded and that there is no reason to want to do that. "Just trust block explorer websites". And the post and comment were highly upvoted. Really? You really think that there is no problem in having just a few nodes on the network? And that the only thing that secures the network are miners? As stated by user u/co1nsurf3r in that thread:
While I don't think that everybody needs to run a node, a full node does publish blocks it considers valid to other nodes. This does not amount to much if you only consider a single node in the network, but many "honest" full nodes in the network will reduce the probability of a valid block being withheld from the network by a collusion of "hostile" node operators.
But surely this will not get attention here, and will be downvoted by those people that promote the narrative that there is no trade off in increasing the blocksize and the people that don't see it are retarded or are btc maxis. The only narrative I stick to and have been for many years now is that cryptocurrency takes power from the government and gives power to the individual, so you are not restricted to your economy as you can participate in the global economy. There is also the narrative of banking the bankless, which I hope will come true, but it is not a use case we are seeing right now. Some people would argue that removing power from gov's is a bad thing, but you can't deny the fact that gov's can't control crypto (at least we would want them not to). But, if you really want the individuals to remain in control of their money and transact with anyone in the world, the network needs to be very resistant to any kind of attacks. How can you have p2p electronic cash if your network just has a handful couple of nodes and the chinese gov can locate them and just block communication to them? I'm not saying that this is BCH case, I'm just refuting the fact that there is no value in running your own node. If you are relying on block explorers, the gov can just block the communication to the block explorer websites. Then what? Who will you trust to get chain information? The nodes needs to be decentralized so if you take one node down, many more can appear so it is hard to censor and you don't have few points of failure. Right now BTC is focusing on that use case of being difficult to censor. But with that comes the problem that is very expensive to transact on the network, which breaks the purpose of anyone being able to participate. Obviously I do think that is also a major problem, and lightning network is awful right now and probably still years away of being usable, if it ever will. The best solution is up for debate, but thinking that you just have to increase the blocksize and there is no trade off is just naive or misleading. BCH is doing a good thing in trying to come with a solution that is inclusive and promotes cheap and fast transactions, but also don't forget centralization is a major concern and nothing to just shrug off. Saying that "a 1 MB blocksize enables poor people to run their own" and that because of that "Poor people won’t be able to use the network" is a misrepresentation designed to promote a narrative. Because 1MB is not to allow "poor" people to run their node, it is to facilitate as many people to run a node to promote decentralization and avoid censorship. Also an elephant in the room that you will not see being discussed in either BTC or BCH communities is that mining pools are heavily centralized. And I'm not talking about miners being mostly in china, but also that big pools control a lot of hashing power both in BTC and BCH, and that is terrible for the purpose of crypto. Other projects are trying to solve that. Will they be successful? I don't know, I hope so, because I don't buy into any narrative. There are many challenges and I want to see crypto succeed as a whole. As always guys, DYOR and always question if you are not blindly following a narrative. I'm sure I will be called BTC maxi but maybe some people will find value in this. Don't trust guys that are always posting silly "gocha's" against the other "tribe". EDIT: User u/ShadowOfHarbringer has pointed me to some threads that this has been discussed in the past and I will just put my take on them here for visibility, as I will be using this thread as a reference in future discussions I engage:
When there was only 2 nodes in the network, adding a third node increased redundancy and resiliency of the network as a whole in a significant way. When there is thousands of nodes in the network, adding yet another node only marginally increase the redundancy and resiliency of the network. So the question then becomes a matter of personal judgement of how much that added redundancy and resiliency is worth. For the absolutist, it is absolutely worth it and everyone on this planet should do their part.
What is the magical number of nodes that makes it counterproductive to add new nodes? Did he do any math? Does BCH achieve this holy grail safe number of nodes? Guess what, nobody knows at what number of nodes is starts to be marginally irrelevant to add new nodes. Even BTC today could still not have enough nodes to be safe. If you can't know for sure that you are safe, it is better to try to be safer than sorry. Thousands of nodes is still not enough, as I said, it is much cheaper to run a full node as it is to mine. If it costs millions in hash power to do a 51% attack on the block generation it means nothing if it costs less than $10k to run more nodes than there are in total in the network and cause havoc and slowing people from using the network. Or using bot farms to DDoS the 1000s of nodes in the network. Not all attacks are monetarily motivated. When you have governments with billions of dollars at their disposal and something that could threat their power they could do anything they could to stop people from using it, and the cheapest it is to do so the better
You should run a full node if you're a big business with e.g. >$100k/month in volume, or if you run a service that requires high fraud resistance and validation certainty for payments sent your way (e.g. an exchange). For most other users of Bitcoin, there's no good reason to run a full node unless you reel like it.
Shouldn't individuals benefit from fraud resistance too? Why just businesses?
Personally, I think it's a good idea to make sure that people can easily run a full node because they feel like it, and that it's desirable to keep full node resource requirements reasonable for an enthusiast/hobbyist whenever possible. This might seem to be at odds with the concept of making a worldwide digital cash system in which all transactions are validated by everybody, but after having done the math and some of the code myself, I believe that we should be able to have our cake and eat it too.
This is recurrent argument, but also no math provided, "just trust me I did the math"
The biggest reason individuals may want to run their own node is to increase their privacy. SPV wallets rely on others (nodes or ElectronX servers) who may learn their addresses.
It is a reason and valid one but not the biggest reason
If you do it for fun and experimental it good. If you do it for extra privacy it's ok. If you do it to help the network don't. You are just slowing down miners and exchanges.
Yes it will slow down the network, but that shows how people just don't get the the trade off they are doing
I will just copy/paste what Satoshi Nakamoto said in his own words. "The current system where every user is a network node is not the intended configuration for large scale. That would be like every Usenet user runs their own NNTP server."
Another "it is all or nothing argument" and quoting satoshi to try and prove their point. Just because every user doesn't need to be also a full node doesn't mean that there aren't serious risks for having few nodes
For this to have any importance in practice, all of the miners, all of the exchanges, all of the explorers and all of the economic nodes should go rogue all at once. Collude to change consensus. If you have a node you can detect this. It doesn't do much, because such a scenario is impossible in practice.
Not true because as I said, you can DDoS the current nodes or run more malicious nodes than that there currently are, because is cheap to do so
Non-mining nodes don't contribute to adding data to the blockchain ledger, but they do play a part in propagating transactions that aren't yet in blocks (the mempool). Bitcoin client implementations can have different validations for transactions they see outside of blocks and transactions they see inside of blocks; this allows for "soft forks" to add new types of transactions without completely breaking older clients (while a transaction is in the mempool, a node receiving a transaction that's a new/unknown type could drop it as not a valid transaction (not propagate it to its peers), but if that same transaction ends up in a block and that node receives the block, they accept the block (and the transaction in it) as valid (and therefore don't get left behind on the blockchain and become a fork). The participation in the mempool is a sort of "herd immunity" protection for the network, and it was a key talking point for the "User Activated Soft Fork" (UASF) around the time the Segregated Witness feature was trying to be added in. If a certain percentage of nodes updated their software to not propagate certain types of transactions (or not communicate with certain types of nodes), then they can control what gets into a block (someone wanting to get that sort of transaction into a block would need to communicate directly to a mining node, or communicate only through nodes that weren't blocking that sort of transaction) if a certain threshold of nodes adheres to those same validation rules. It's less specific than the influence on the blockchain data that mining nodes have, but it's definitely not nothing.
The first reasonable comment in that thread but is deep down there with only 1 upvote
The addition of non-mining nodes does not add to the efficiency of the network, but actually takes away from it because of the latency issue.
That is true and is actually a trade off you are making, sacrificing security to have scalability
The addition of non-mining nodes has little to no effect on security, since you only need to destroy mining ones to take down the network
It is true that if you destroy mining nodes you take down the network from producing new blocks (temporarily), even if you have a lot of non mining nodes. But, it still better than if you take down the mining nodes who are also the only full nodes. If the miners are not the only full nodes, at least you still have full nodes with the blockchain data so new miners can download it and join. If all the miners are also the full nodes and you take them down, where will you get all the past blockchain data to start mining again? Just pray that the miners that were taken down come back online at some point in the future?
The real limiting factor is ISP's: Imagine a situation where one service provider defrauds 4000 different nodes. Did the excessive amount of nodes help at all, when they have all been defrauded by the same service provider? If there are only 30 ISP's in the world, how many nodes do we REALLY need?
You cant defraud if the connection is encrypted. Use TOR for example, it is hard for ISP's to know what you are doing.
Satoshi specifically said in the white paper that after a certain point, number of nodes needed plateaus, meaning after a certain point, adding more nodes is actually counterintuitive, which we also demonstrated. (the latency issue). So, we have adequately demonstrated why running non-mining nodes does not add additional value or security to the network.
Again, what is the number of nodes that makes it counterproductive? Did he do any math?
There's also the matter of economically significant nodes and the role they play in consensus. Sure, nobody cares about your average joe's "full node" where he is "keeping his own ledger to keep the miners honest", as it has no significance to the economy and the miners couldn't give a damn about it. However, if say some major exchanges got together to protest a miner activated fork, they would have some protest power against that fork because many people use their service. Of course, there still needs to be miners running on said "protest fork" to keep the chain running, but miners do follow the money and if they got caught mining a fork that none of the major exchanges were trading, they could be coaxed over to said "protest fork".
In consensus, what matters about nodes is only the number, economical power of the node doesn't mean nothing, the protocol doesn't see the net worth of the individual or organization running that node.
Running a full node that is not mining and not involved is spending or receiving payments is of very little use. It helps to make sure network traffic is broadcast, and is another copy of the blockchain, but that is all (and is probably not needed in a healthy coin with many other nodes)
He gets it right (broadcasting transaction and keeping a copy of the blockchain) but he dismisses the importance of it

You have a certain amount of resources that a network can process and you have a certain demand. And that will naturally result in fees based on supply / demand what you can do however is to build a system where the actual users of that system that legitimately want to use it can do so for free, just because they already "invest" enough by having tokens or running infrastructure they are already contributing to the well-being of the network through these two aspects alone it would be stupid to ask those guys for additional fees and mana essentially tries to be such a measure of honesty among the users 📷 Hyperware어제 오후 11:47 It's interesting from an investment perspective that having tokens/mana is like owning a portion of the network. 📷 Hans Moog [IF]어제 오후 11:48 Yeah, you are owning a certain % of the throughput and whatever the price will ultimately be to execute on this network - you will earn proportionally but you have to keep in mind that we are trying to build the most efficient DLT that you could possibly ever build 📷 semibaron어제 오후 11:48 The whole mana (tokens) = share of network throuput sounds very much like EOS tbh Just that EOS uses DPoS 📷 Hans Moog [IF]어제 오후 11:50 yeah i mean there is really not too many new things under the sun - you can just tweak a few things here and there, when it comes to distributing resources DPoS is simply not very nice from a centralization aspect 📷 Hans Moog [IF]어제 오후 11:50 at least not the way EOS does it delegating weights is 1 thing but assuming that the weight will always be in a way that 21 "identities" run the whole network is bad in the current world you see a centralization of power but ultimately we want to build a future where the wealth is more evenly distributed and the same goes for voting power 📷 Hans Moog [IF]어제 오후 11:52 blockchain needs leader selection it only works with such a centralizing component IOTA doesn't need that it's delusional to say that IOTA wouldn't have any such centralization but maybe we get better than just a handselected nodes📷 📷 Phantom3D어제 오후 11:52 How would this affect a regular hodler without a node.

This is the actually important piece of info! 📷 Basha오늘 오전 5:38 ok, i thought it was communicated that you need at least 1 mana to process a transaction. from the blogpost: "... a node with 0 mana can issue no transactions." maybe they meant during the congestion, but if that's the case maybe you should add that 📷 Hans Moog [IF]오늘 오전 5:42 its under the point "Congestion control:" yeah this only applies to spam attacks network not overloaded = no mana needed 📷 Hans Moog [IF]오늘 오전 5:43 if congested => favor txs from people who have the most skin in the game but sharding will try to keep the network non-congested most of the time - but there might be short periods of time where an attacker might bring the network close to its limits and of course its going to take a while to add this, so we need a protection mechanism till sharding is supported(수정됨) 📷 Hans Moog [IF]오늘 오전 6:36 I don't have a particular problem with EOS or their amount of validators - the reason why I think blockchain is inferior has really nothing to do with the way you do sybil protection and with validators I mean "voting nodes" I mean even bitcoin has less mining pools and you could compare mining pools to dpos in some sense where people assign their weight (in that case hashing power) to the corresponding mining pools so EOS is definitely not less decentralized than any other tech but having more identities having weight in the decision process definitely makes it harder to corrupt a reasonable fraction of the system and makes it easier to shard so its desirable to have this property(수정됨) ------------------------------------------------- 📷 Antonio Nardella [IF]오늘 오전 3:36
https://github.com/gridcoin-community/Gridcoin-Research/releases/tag/220.127.116.11 Finally! After over ten months of development and testing, "Fern" has arrived! This is a whopper. 240 pull requests merged. Essentially a complete rewrite that was started with the scraper (the "neural net" rewrite) in "Denise" has now been completed. Practically the ENTIRE Gridcoin specific codebase resting on top of the vanilla Bitcoin/Peercoin/Blackcoin vanilla PoS code has been rewritten. This removes the team requirement at last (see below), although there are many other important improvements besides that. Fern was a monumental undertaking. We had to encode all of the old rules active for the v10 block protocol in new code and ensure that the new code was 100% compatible. This had to be done in such a way as to clear out all of the old spaghetti and ring-fence it with tightly controlled class implementations. We then wrote an entirely new, simplified ruleset for research rewards and reengineered contracts (which includes beacon management, polls, and voting) using properly classed code. The fundamentals of Gridcoin with this release are now on a very sound and maintainable footing, and the developers believe the codebase as updated here will serve as the fundamental basis for Gridcoin's future roadmap. We have been testing this for MONTHS on testnet in various stages. The v10 (legacy) compatibility code has been running on testnet continuously as it was developed to ensure compatibility with existing nodes. During the last few months, we have done two private testnet forks and then the full public testnet testing for v11 code (the new protocol which is what Fern implements). The developers have also been running non-staking "sentinel" nodes on mainnet with this code to verify that the consensus rules are problem-free for the legacy compatibility code on the broader mainnet. We believe this amount of testing is going to result in a smooth rollout. Given the amount of changes in Fern, I am presenting TWO changelogs below. One is high level, which summarizes the most significant changes in the protocol. The second changelog is the detailed one in the usual format, and gives you an inkling of the size of this release.
Note that the protocol changes will not become active until we cross the hard-fork transition height to v11, which has been set at 2053000. Given current average block spacing, this should happen around October 4, about one month from now. Note that to get all of the beacons in the network on the new protocol, we are requiring ALL beacons to be validated. A two week (14 day) grace period is provided by the code, starting at the time of the transition height, for people currently holding a beacon to validate the beacon and prevent it from expiring. That means that EVERY CRUNCHER must advertise and validate their beacon AFTER the v11 transition (around Oct 4th) and BEFORE October 18th (or more precisely, 14 days from the actual date of the v11 transition). If you do not advertise and validate your beacon by this time, your beacon will expire and you will stop earning research rewards until you advertise and validate a new beacon. This process has been made much easier by a brand new beacon "wizard" that helps manage beacon advertisements and renewals. Once a beacon has been validated and is a v11 protocol beacon, the normal 180 day expiration rules apply. Note, however, that the 180 day expiration on research rewards has been removed with the Fern update. This means that while your beacon might expire after 180 days, your earned research rewards will be retained and can be claimed by advertising a beacon with the same CPID and going through the validation process again. In other words, you do not lose any earned research rewards if you do not stake a block within 180 days and keep your beacon up-to-date. The transition height is also when the team requirement will be relaxed for the network.
Besides the beacon wizard, there are a number of improvements to the GUI, including new UI transaction types (and icons) for staking the superblock, sidestake sends, beacon advertisement, voting, poll creation, and transactions with a message. The main screen has been revamped with a better summary section, and better status icons. Several changes under the hood have improved GUI performance. And finally, the diagnostics have been revamped.
The wallet sync speed has been DRASTICALLY improved. A decent machine with a good network connection should be able to sync the entire mainnet blockchain in less than 4 hours. A fast machine with a really fast network connection and a good SSD can do it in about 2.5 hours. One of our goals was to reduce or eliminate the reliance on snapshots for mainnet, and I think we have accomplished that goal with the new sync speed. We have also streamlined the in-memory structures for the blockchain which shaves some memory use. There are so many goodies here it is hard to summarize them all. I would like to thank all of the contributors to this release, but especially thank @cyrossignol, whose incredible contributions formed the backbone of this release. I would also like to pay special thanks to @barton2526, @caraka, and @Quezacoatl1, who tirelessly helped during the testing and polishing phase on testnet with testing and repeated builds for all architectures. The developers are proud to present this release to the community and we believe this represents the starting point for a true renaissance for Gridcoin!
Most significantly, nodes calculate research rewards directly from the magnitudes in EACH superblock between stakes instead of using a two- or three- point average based on a CPID's current magnitude and the magnitude for the CPID when it last staked. For those long-timers in the community, this has been referred to as "Superblock Windows," and was first done in proof-of-concept form by @denravonska.
Network magnitude unit pinned to a static value of 0.25
Max research reward allowed per block raised to 16384 GRC (from 12750 GRC)
New CPIDs begin accruing research rewards from the first superblock that contains the CPID instead of from the time of the beacon advertisement
500 GRC research reward limit for a CPID's first stake
6-month expiration for unclaimed rewards
10-block spacing requirement between research reward claims
Rolling 5-day payment-per-day limit
Legacy tolerances for floating-point error and time drift
The need to include a valid copy of a CPID's magnitude in a claim
10-block emission adjustment interval for the magnitude unit
One-time beacon activation requires that participants temporarily change their usernames to a verification code at one whitelisted BOINC project
Verification codes of pending beacons expire after 3 days
Self-service beacon removal
Burn fee for beacon advertisement increased from 0.00001 GRC to 0.5 GRC
Rain addresses derived from beacon keys instead of a default wallet address
Beacon expiration determined as of the current block instead of the previous block
The ability for developers to remove beacons
The ability to sign research reward claims with non-current but unexpired beacons
As a reminder:
Beacons expire after 6 months pass (180 days)
Beacons can be renewed after 5 months pass (150 days)
Renewed beacons must be signed with the same key as the original beacon
Magnitudes less than 1 include two fractional places
Magnitudes greater than or equal to 1 but less than 10 include one fractional place
A valid superblock must match a scraper convergence
Superblock popularity election mechanics
Yes/no/abstain and single-choice response types (no user-facing support yet)
To create a poll, a maximum of 250 UTXOs for a single address must add up to 100000 GRC. These are selected from the largest downwards.
Burn fee for creating polls scaled by the number of UTXOs claimed
50 GRC for a poll contract
0.001 GRC per claimed UTXO
Burn fee for casting votes scaled by the number of UTXOs claimed
0.01 GRC for a vote contract
0.01 GRC to claim magnitude
0.01 GRC per claimed address
0.001 GRC per claimed UTXO

Hey all, I've been researching coins since 2017 and have gone through 100s of them in the last 3 years. I got introduced to blockchain via Bitcoin of course, analyzed Ethereum thereafter and from that moment I have a keen interest in smart contact platforms. I’m passionate about Ethereum but I find Zilliqa to have a better risk-reward ratio. Especially because Zilliqa has found an elegant balance between being secure, decentralized and scalable in my opinion.
Below I post my analysis of why from all the coins I went through I’m most bullish on Zilliqa (yes I went through Tezos, EOS, NEO, VeChain, Harmony, Algorand, Cardano etc.). Note that this is not investment advice and although it's a thorough analysis there is obviously some bias involved. Looking forward to what you all think!
Fun fact: the name Zilliqa is a play on ‘silica’ silicon dioxide which means “Silicon for the high-throughput consensus computer.”
This post is divided into (i) Technology, (ii) Business & Partnerships, and (iii) Marketing & Community. I’ve tried to make the technology part readable for a broad audience. If you’ve ever tried understanding the inner workings of Bitcoin and Ethereum you should be able to grasp most parts. Otherwise, just skim through and once you are zoning out head to the next part.
Technology and some more:
The technology is one of the main reasons why I’m so bullish on Zilliqa. First thing you see on their website is: “Zilliqa is a high-performance, high-security blockchain platform for enterprises and next-generation applications.” These are some bold statements.
Before we deep dive into the technology let’s take a step back in time first as they have quite the history. The initial research paper from which Zilliqa originated dates back to August 2016: Elastico: A Secure Sharding Protocol For Open Blockchains where Loi Luu (Kyber Network) is one of the co-authors. Other ideas that led to the development of what Zilliqa has become today are: Bitcoin-NG, collective signing CoSi, ByzCoin and Omniledger.
The technical white paper was made public in August 2017 and since then they have achieved everything stated in the white paper and also created their own open source intermediate level smart contract language called Scilla (functional programming language similar to OCaml) too.
Mainnet is live since the end of January 2019 with daily transaction rates growing continuously. About a week ago mainnet reached 5 million transactions, 500.000+ addresses in total along with 2400 nodes keeping the network decentralized and secure. Circulating supply is nearing 11 billion and currently only mining rewards are left. The maximum supply is 21 billion with annual inflation being 7.13% currently and will only decrease with time.
Zilliqa realized early on that the usage of public cryptocurrencies and smart contracts were increasing but decentralized, secure, and scalable alternatives were lacking in the crypto space. They proposed to apply sharding onto a public smart contract blockchain where the transaction rate increases almost linear with the increase in the amount of nodes. More nodes = higher transaction throughput and increased decentralization. Sharding comes in many forms and Zilliqa uses network-, transaction- and computational sharding. Network sharding opens up the possibility of using transaction- and computational sharding on top. Zilliqa does not use state sharding for now. We’ll come back to this later.
Before we continue dissecting how Zilliqa achieves such from a technological standpoint it’s good to keep in mind that a blockchain being decentralised and secure and scalable is still one of the main hurdles in allowing widespread usage of decentralised networks. In my opinion this needs to be solved first before blockchains can get to the point where they can create and add large scale value. So I invite you to read the next section to grasp the underlying fundamentals. Because after all these premises need to be true otherwise there isn’t a fundamental case to be bullish on Zilliqa, right?
Down the rabbit hole
How have they achieved this? Let’s define the basics first: key players on Zilliqa are the users and the miners. A user is anybody who uses the blockchain to transfer funds or run smart contracts. Miners are the (shard) nodes in the network who run the consensus protocol and get rewarded for their service in Zillings (ZIL). The mining network is divided into several smaller networks called shards, which is also referred to as ‘network sharding’. Miners subsequently are randomly assigned to a shard by another set of miners called DS (Directory Service) nodes. The regular shards process transactions and the outputs of these shards are eventually combined by the DS shard as they reach consensus on the final state. More on how these DS shards reach consensus (via pBFT) will be explained later on.
The Zilliqa network produces two types of blocks: DS blocks and Tx blocks. One DS Block consists of 100 Tx Blocks. And as previously mentioned there are two types of nodes concerned with reaching consensus: shard nodes and DS nodes. Becoming a shard node or DS node is being defined by the result of a PoW cycle (Ethash) at the beginning of the DS Block. All candidate mining nodes compete with each other and run the PoW (Proof-of-Work) cycle for 60 seconds and the submissions achieving the highest difficulty will be allowed on the network. And to put it in perspective: the average difficulty for one DS node is ~ 2 Th/s equaling 2.000.000 Mh/s or 55 thousand+ GeForce GTX 1070 / 8 GB GPUs at 35.4 Mh/s. Each DS Block 10 new DS nodes are allowed. And a shard node needs to provide around 8.53 GH/s currently (around 240 GTX 1070s). Dual mining ETH/ETC and ZIL is possible and can be done via mining software such as Phoenix and Claymore. There are pools and if you have large amounts of hashing power (Ethash) available you could mine solo.
The PoW cycle of 60 seconds is a peak performance and acts as an entry ticket to the network. The entry ticket is called a sybil resistance mechanism and makes it incredibly hard for adversaries to spawn lots of identities and manipulate the network with these identities. And after every 100 Tx Blocks which corresponds to roughly 1,5 hour this PoW process repeats. In between these 1,5 hour, no PoW needs to be done meaning Zilliqa’s energy consumption to keep the network secure is low. For more detailed information on how mining works click here. Okay, hats off to you. You have made it this far. Before we go any deeper down the rabbit hole we first must understand why Zilliqa goes through all of the above technicalities and understand a bit more what a blockchain on a more fundamental level is. Because the core of Zilliqa’s consensus protocol relies on the usage of pBFT (practical Byzantine Fault Tolerance) we need to know more about state machines and their function. Navigate to Viewblock, a Zilliqa block explorer, and just come back to this article. We will use this site to navigate through a few concepts.
We have established that Zilliqa is a public and distributed blockchain. Meaning that everyone with an internet connection can send ZILs, trigger smart contracts, etc. and there is no central authority who fully controls the network. Zilliqa and other public and distributed blockchains (like Bitcoin and Ethereum) can also be defined as state machines.
Taking the liberty of paraphrasing examples and definitions given by Samuel Brooks’ medium article, he describes the definition of a blockchain (like Zilliqa) as: “A peer-to-peer, append-only datastore that uses consensus to synchronize cryptographically-secure data”.
Next, he states that: "blockchains are fundamentally systems for managing valid state transitions”. For some more context, I recommend reading the whole medium article to get a better grasp of the definitions and understanding of state machines. Nevertheless, let’s try to simplify and compile it into a single paragraph. Take traffic lights as an example: all its states (red, amber, and green) are predefined, all possible outcomes are known and it doesn’t matter if you encounter the traffic light today or tomorrow. It will still behave the same. Managing the states of a traffic light can be done by triggering a sensor on the road or pushing a button resulting in one traffic lights’ state going from green to red (via amber) and another light from red to green.
With public blockchains like Zilliqa, this isn’t so straightforward and simple. It started with block #1 almost 1,5 years ago and every 45 seconds or so a new block linked to the previous block is being added. Resulting in a chain of blocks with transactions in it that everyone can verify from block #1 to the current #647.000+ block. The state is ever changing and the states it can find itself in are infinite. And while the traffic light might work together in tandem with various other traffic lights, it’s rather insignificant comparing it to a public blockchain. Because Zilliqa consists of 2400 nodes who need to work together to achieve consensus on what the latest valid state is while some of these nodes may have latency or broadcast issues, drop offline or are deliberately trying to attack the network, etc.
Now go back to the Viewblock page take a look at the amount of transaction, addresses, block and DS height and then hit refresh. Obviously as expected you see new incremented values on one or all parameters. And how did the Zilliqa blockchain manage to transition from a previous valid state to the latest valid state? By using pBFT to reach consensus on the latest valid state.
After having obtained the entry ticket, miners execute pBFT to reach consensus on the ever-changing state of the blockchain. pBFT requires a series of network communication between nodes, and as such there is no GPU involved (but CPU). Resulting in the total energy consumed to keep the blockchain secure, decentralized and scalable being low.
pBFT stands for practical Byzantine Fault Tolerance and is an optimization on the Byzantine Fault Tolerant algorithm. To quote Blockonomi: “In the context of distributed systems, Byzantine Fault Tolerance is the ability of a distributed computer network to function as desired and correctly reach a sufficient consensus despite malicious components (nodes) of the system failing or propagating incorrect information to other peers.” Zilliqa is such a distributed computer network and depends on the honesty of the nodes (shard and DS) to reach consensus and to continuously update the state with the latest block. If pBFT is a new term for you I can highly recommend the Blockonomi article.
The idea of pBFT was introduced in 1999 - one of the authors even won a Turing award for it - and it is well researched and applied in various blockchains and distributed systems nowadays. If you want more advanced information than the Blockonomi link provides click here. And if you’re in between Blockonomi and the University of Singapore read the Zilliqa Design Story Part 2 dating from October 2017. Quoting from the Zilliqa tech whitepaper: “pBFT relies upon a correct leader (which is randomly selected) to begin each phase and proceed when the sufficient majority exists. In case the leader is byzantine it can stall the entire consensus protocol. To address this challenge, pBFT offers a view change protocol to replace the byzantine leader with another one.”
pBFT can tolerate ⅓ of the nodes being dishonest (offline counts as Byzantine = dishonest) and the consensus protocol will function without stalling or hiccups. Once there are more than ⅓ of dishonest nodes but no more than ⅔ the network will be stalled and a view change will be triggered to elect a new DS leader. Only when more than ⅔ of the nodes are dishonest (66%) double-spend attacks become possible.
If the network stalls no transactions can be processed and one has to wait until a new honest leader has been elected. When the mainnet was just launched and in its early phases, view changes happened regularly. As of today the last stalling of the network - and view change being triggered - was at the end of October 2019.
Another benefit of using pBFT for consensus besides low energy is the immediate finality it provides. Once your transaction is included in a block and the block is added to the chain it’s done. Lastly, take a look at this article where three types of finality are being defined: probabilistic, absolute and economic finality. Zilliqa falls under the absolute finality (just like Tendermint for example). Although lengthy already we skipped through some of the inner workings from Zilliqa’s consensus: read the Zilliqa Design Story Part 3 and you will be close to having a complete picture on it. Enough about PoW, sybil resistance mechanism, pBFT, etc. Another thing we haven’t looked at yet is the amount of decentralization.
Currently, there are four shards, each one of them consisting of 600 nodes. 1 shard with 600 so-called DS nodes (Directory Service - they need to achieve a higher difficulty than shard nodes) and 1800 shard nodes of which 250 are shard guards (centralized nodes controlled by the team). The amount of shard guards has been steadily declining from 1200 in January 2019 to 250 as of May 2020. On the Viewblock statistics, you can see that many of the nodes are being located in the US but those are only the (CPU parts of the) shard nodes who perform pBFT. There is no data from where the PoW sources are coming. And when the Zilliqa blockchain starts reaching its transaction capacity limit, a network upgrade needs to be executed to lift the current cap of maximum 2400 nodes to allow more nodes and formation of more shards which will allow to network to keep on scaling according to demand. Besides shard nodes there are also seed nodes. The main role of seed nodes is to serve as direct access points (for end-users and clients) to the core Zilliqa network that validates transactions. Seed nodes consolidate transaction requests and forward these to the lookup nodes (another type of nodes) for distribution to the shards in the network. Seed nodes also maintain the entire transaction history and the global state of the blockchain which is needed to provide services such as block explorers. Seed nodes in the Zilliqa network are comparable to Infura on Ethereum.
The seed nodes were first only operated by Zilliqa themselves, exchanges and Viewblock. Operators of seed nodes like exchanges had no incentive to open them for the greater public. They were centralised at first. Decentralisation at the seed nodes level has been steadily rolled out since March 2020 ( Zilliqa Improvement Proposal 3 ). Currently the amount of seed nodes is being increased, they are public-facing and at the same time PoS is applied to incentivize seed node operators and make it possible for ZIL holders to stake and earn passive yields. Important distinction: seed nodes are not involved with consensus! That is still PoW as entry ticket and pBFT for the actual consensus.
5% of the block rewards are being assigned to seed nodes (from the beginning in 2019) and those are being used to pay out ZIL stakers. The 5% block rewards with an annual yield of 10.03% translate to roughly 610 MM ZILs in total that can be staked. Exchanges use the custodial variant of staking and wallets like Moonlet will use the non-custodial version (starting in Q3 2020). Staking is being done by sending ZILs to a smart contract created by Zilliqa and audited by Quantstamp.
With a high amount of DS; shard nodes and seed nodes becoming more decentralized too, Zilliqa qualifies for the label of decentralized in my opinion.
Generalized: programming languages can be divided into being ‘object-oriented’ or ‘functional’. Here is an ELI5 given by software development academy: * “all programs have two basic components, data – what the program knows – and behavior – what the program can do with that data. So object-oriented programming states that combining data and related behaviors in one place, is called “object”, which makes it easier to understand how a particular program works. On the other hand, functional programming argues that data and behavior are different things and should be separated to ensure their clarity.” *
Scilla is on the functional side and shares similarities with OCaml: OCaml is a general-purpose programming language with an emphasis on expressiveness and safety. It has an advanced type system that helps catch your mistakes without getting in your way. It's used in environments where a single mistake can cost millions and speed matters, is supported by an active community, and has a rich set of libraries and development tools. For all its power, OCaml is also pretty simple, which is one reason it's often used as a teaching language.
Scilla is blockchain agnostic, can be implemented onto other blockchains as well, is recognized by academics and won a so-called Distinguished Artifact Award award at the end of last year.
One of the reasons why the Zilliqa team decided to create their own programming language focused on preventing smart contract vulnerabilities is that adding logic on a blockchain, programming, means that you cannot afford to make mistakes. Otherwise, it could cost you. It’s all great and fun blockchains being immutable but updating your code because you found a bug isn’t the same as with a regular web application for example. And with smart contracts, it inherently involves cryptocurrencies in some form thus value.
Another difference with programming languages on a blockchain is gas. Every transaction you do on a smart contract platform like Zilliqa or Ethereum costs gas. With gas you basically pay for computational costs. Sending a ZIL from address A to address B costs 0.001 ZIL currently. Smart contracts are more complex, often involve various functions and require more gas (if gas is a new concept click here ).
So with Scilla, similar to Solidity, you need to make sure that “every function in your smart contract will run as expected without hitting gas limits. An improper resource analysis may lead to situations where funds may get stuck simply because a part of the smart contract code cannot be executed due to gas limits. Such constraints are not present in traditional software systems”.Scilla design story part 1
Some examples of smart contract issues you’d want to avoid are: leaking funds, ‘unexpected changes to critical state variables’ (example: someone other than you setting his or her address as the owner of the smart contract after creation) or simply killing a contract.
Scilla also allows for formal verification. Wikipedia to the rescue: In the context of hardware and software systems, formal verification is the act of proving or disproving the correctness of intended algorithms underlying a system with respect to a certain formal specification or property, using formal methods of mathematics.
Formal verification can be helpful in proving the correctness of systems such as: cryptographic protocols, combinational circuits, digital circuits with internal memory, and software expressed as source code.
“Scilla is being developed hand-in-hand with formalization of its semantics and its embedding into the Coq proof assistant — a state-of-the art tool for mechanized proofs about properties of programs.”
Simply put, with Scilla and accompanying tooling developers can be mathematically sure and proof that the smart contract they’ve written does what he or she intends it to do.
Smart contract on a sharded environment and state sharding
There is one more topic I’d like to touch on: smart contract execution in a sharded environment (and what is the effect of state sharding). This is a complex topic. I’m not able to explain it any easier than what is posted here. But I will try to compress the post into something easy to digest.
Earlier on we have established that Zilliqa can process transactions in parallel due to network sharding. This is where the linear scalability comes from. We can define simple transactions: a transaction from address A to B (Category 1), a transaction where a user interacts with one smart contract (Category 2) and the most complex ones where triggering a transaction results in multiple smart contracts being involved (Category 3). The shards are able to process transactions on their own without interference of the other shards. With Category 1 transactions that is doable, with Category 2 transactions sometimes if that address is in the same shard as the smart contract but with Category 3 you definitely need communication between the shards. Solving that requires to make a set of communication rules the protocol needs to follow in order to process all transactions in a generalised fashion.
There is no strict defined roadmap but here are topics being worked on. And via the Zilliqa website there is also more information on the projects they are working on.
Business & Partnerships
It’s not only technology in which Zilliqa seems to be excelling as their ecosystem has been expanding and starting to grow rapidly. The project is on a mission to provide OpenFinance (OpFi) to the world and Singapore is the right place to be due to its progressive regulations and futuristic thinking. Singapore has taken a proactive approach towards cryptocurrencies by introducing the Payment Services Act 2019 (PS Act). Among other things, the PS Act will regulate intermediaries dealing with certain cryptocurrencies, with a particular focus on consumer protection and anti-money laundering. It will also provide a stable regulatory licensing and operating framework for cryptocurrency entities, effectively covering all crypto businesses and exchanges based in Singapore. According to PWC 82% of the surveyed executives in Singapore reported blockchain initiatives underway and 13% of them have already brought the initiatives live to the market. There is also an increasing list of organizations that are starting to provide digital payment services. Moreover, Singaporean blockchain developers Building Cities Beyond has recently created an innovation $15 million grant to encourage development on its ecosystem. This all suggests that Singapore tries to position itself as (one of) the leading blockchain hubs in the world.
Zilliqa seems to already take advantage of this and recently helped launch Hg Exchange on their platform, together with financial institutions PhillipCapital, PrimePartners and Fundnel. Hg Exchange, which is now approved by the Monetary Authority of Singapore (MAS), uses smart contracts to represent digital assets. Through Hg Exchange financial institutions worldwide can use Zilliqa's safe-by-design smart contracts to enable the trading of private equities. For example, think of companies such as Grab, Airbnb, SpaceX that are not available for public trading right now. Hg Exchange will allow investors to buy shares of private companies & unicorns and capture their value before an IPO. Anquan, the main company behind Zilliqa, has also recently announced that they became a partner and shareholder in TEN31 Bank, which is a fully regulated bank allowing for tokenization of assets and is aiming to bridge the gap between conventional banking and the blockchain world. If STOs, the tokenization of assets, and equity trading will continue to increase, then Zilliqa’s public blockchain would be the ideal candidate due to its strategic positioning, partnerships, regulatory compliance and the technology that is being built on top of it.
What is also very encouraging is their focus on banking the un(der)banked. They are launching a stablecoin basket starting with XSGD. As many of you know, stablecoins are currently mostly used for trading. However, Zilliqa is actively trying to broaden the use case of stablecoins. I recommend everybody to read this text that Amrit Kumar wrote (one of the co-founders). These stablecoins will be integrated in the traditional markets and bridge the gap between the crypto world and the traditional world. This could potentially revolutionize and legitimise the crypto space if retailers and companies will for example start to use stablecoins for payments or remittances, instead of it solely being used for trading.
Zilliqa also released their DeFi strategic roadmap (dating November 2019) which seems to be aligning well with their OpFi strategy. A non-custodial DEX is coming to Zilliqa made by Switcheo which allows cross-chain trading (atomic swaps) between ETH, EOS and ZIL based tokens. They also signed a Memorandum of Understanding for a (soon to be announced) USD stablecoin. And as Zilliqa is all about regulations and being compliant, I’m speculating on it to be a regulated USD stablecoin. Furthermore, XSGD is already created and visible on block explorer and XIDR (Indonesian Stablecoin) is also coming soon via StraitsX. Here also an overview of the Tech Stack for Financial Applications from September 2019. Further quoting Amrit Kumar on this:
There are two basic building blocks in DeFi/OpFi though: 1) stablecoins as you need a non-volatile currency to get access to this market and 2) a dex to be able to trade all these financial assets. The rest are built on top of these blocks.
So far, together with our partners and community, we have worked on developing these building blocks with XSGD as a stablecoin. We are working on bringing a USD-backed stablecoin as well. We will soon have a decentralised exchange developed by Switcheo. And with HGX going live, we are also venturing into the tokenization space. More to come in the future.”
Additionally, they also have this ZILHive initiative that injects capital into projects. There have been already 6 waves of various teams working on infrastructure, innovation and research, and they are not from ASEAN or Singapore only but global: see Grantees breakdown by country. Over 60 project teams from over 20 countries have contributed to Zilliqa's ecosystem. This includes individuals and teams developing wallets, explorers, developer toolkits, smart contract testing frameworks, dapps, etc. As some of you may know, Unstoppable Domains (UD) blew up when they launched on Zilliqa. UD aims to replace cryptocurrency addresses with a human-readable name and allows for uncensorable websites. Zilliqa will probably be the only one able to handle all these transactions onchain due to ability to scale and its resulting low fees which is why the UD team launched this on Zilliqa in the first place. Furthermore, Zilliqa also has a strong emphasis on security, compliance, and privacy, which is why they partnered with companies like Elliptic, ChainSecurity (part of PwC Switzerland), and Incognito. Their sister company Aqilliz (Zilliqa spelled backwards) focuses on revolutionizing the digital advertising space and is doing interesting things like using Zilliqa to track outdoor digital ads with companies like Foodpanda.
Zilliqa is listed on nearly all major exchanges, having several different fiat-gateways and recently have been added to Binance’s margin trading and futures trading with really good volume. They also have a very impressive team with good credentials and experience. They don't just have “tech people”. They have a mix of tech people, business people, marketeers, scientists, and more. Naturally, it's good to have a mix of people with different skill sets if you work in the crypto space.
Marketing & Community
Zilliqa has a very strong community. If you just follow their Twitter their engagement is much higher for a coin that has approximately 80k followers. They also have been ‘coin of the day’ by LunarCrush many times. LunarCrush tracks real-time cryptocurrency value and social data. According to their data, it seems Zilliqa has a more fundamental and deeper understanding of marketing and community engagement than almost all other coins. While almost all coins have been a bit frozen in the last months, Zilliqa seems to be on its own bull run. It was somewhere in the 100s a few months ago and is currently ranked #46 on CoinGecko. Their official Telegram also has over 20k people and is very active, and their community channel which is over 7k now is more active and larger than many other official channels. Their local communities also seem to be growing.
Moreover, their community started ‘Zillacracy’ together with the Zilliqa core team ( see www.zillacracy.com ). It’s a community-run initiative where people from all over the world are now helping with marketing and development on Zilliqa. Since its launch in February 2020 they have been doing a lot and will also run their own non-custodial seed node for staking. This seed node will also allow them to start generating revenue for them to become a self sustaining entity that could potentially scale up to become a decentralized company working in parallel with the Zilliqa core team. Comparing it to all the other smart contract platforms (e.g. Cardano, EOS, Tezos etc.) they don't seem to have started a similar initiative (correct me if I’m wrong though). This suggests in my opinion that these other smart contract platforms do not fully understand how to utilize the ‘power of the community’. This is something you cannot ‘buy with money’ and gives many projects in the space a disadvantage.
Zilliqa also released two social products called SocialPay and Zeeves. SocialPay allows users to earn ZILs while tweeting with a specific hashtag. They have recently used it in partnership with the Singapore Red Cross for a marketing campaign after their initial pilot program. It seems like a very valuable social product with a good use case. I can see a lot of traditional companies entering the space through this product, which they seem to suggest will happen. Tokenizing hashtags with smart contracts to get network effect is a very smart and innovative idea.
Regarding Zeeves, this is a tipping bot for Telegram. They already have 1000s of signups and they plan to keep upgrading it for more and more people to use it (e.g. they recently have added a quiz features). They also use it during AMAs to reward people in real-time. It’s a very smart approach to grow their communities and get familiar with ZIL. I can see this becoming very big on Telegram. This tool suggests, again, that the Zilliqa team has a deeper understanding of what the crypto space and community needs and is good at finding the right innovative tools to grow and scale.
To be honest, I haven’t covered everything (i’m also reaching the character limited haha). So many updates happening lately that it's hard to keep up, such as the International Monetary Fund mentioning Zilliqa in their report, custodial and non-custodial Staking, Binance Margin, Futures, Widget, entering the Indian market, and more. The Head of Marketing Colin Miles has also released this as an overview of what is coming next. And last but not least, Vitalik Buterin has been mentioning Zilliqa lately acknowledging Zilliqa and mentioning that both projects have a lot of room to grow. There is much more info of course and a good part of it has been served to you on a silver platter. I invite you to continue researching by yourself :-) And if you have any comments or questions please post here!
