Please share your experiences with Bitcoin Mining Pools here.

Hi there,
I run BitcoinsInIreland.com , but am struggling to keep up with all the content I want to write. I'm looking for someone who can assist me on an ad hoc basis, to write reviews around different topics the site covers.
It's not breaking news stuff, but more practical how to guides, step by step reviews of some of the funkier bitcoin things we come across, and helping finish bitcoin mining pool reviews, and review some of the newer ones with out 4x antminer s1 rig.
There's about 40 articles I have in mind that I need help with initially, and can pay a modest amount per article in bitcoin, A portion of the content is gambling related, so this is 18+ only.
So if that's you, you can write, have time over the next few weeks, and want to get in touch, please pm me.
Cheers
Jamie

Hi all,
I got four antminer s1's in September (after buying leased mining since December 13) and after hacking them to each concurrently mine on up to nine pools, I began working my way through the various pools I found on blocktrail. When I started mining, I was daunted by bitcointalk, and couldn't really find any reviews anywhere else, so hopefully it'll let some newer miners check out the options before they start, or if people are thinking of pointing some of their hashing elsewhere, to let them see what's out there.
I've published six out of the eight in this first round, but am looking for ideas for the next eight after this, looking at them through a similar lens.

What is Bitcoins Review?
Bitcoins Review is a website where customers of bitcoin merchant websites can review their experience with the company - similar to a site like tripadvisor.co.uk. The aim is to allow users who are thinking of purchasing a product to check that businesses previous ratings from past customers. Ultimately this will expose the bad or scam websites, which have been somewhat of an issue in previous months, and promote the good, genuine ones. So, not only is this website great for consumers, it is also a valuable tool to maintain a flow of customer feedback and exposure of a shop or service for merchants to take advantage of.

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.)

Quantum Quibbles!

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.

So:

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).

Summary

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!!

That's fine!

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!

Discussions About Taproot Activation

Reddit: https://old.reddit.com/Bitcoin/comments/hqzp14/technical_the_path_to_taproot_activation/

Yesterday a post of mine got a good amount of attention in this, my favourite, sub. So I have decided to post it here in full...
More than mildly, it annoys us that we have the tools to be truly sovereign and yet we continue to submit our ourselves, and our bitcoin, to centralised authorities.
"Privacy is necessary for an open society in the electronic age"; yet KYC is demanded before we can trade.
"Not your keys, not your coins"; yet millions of bitcoin sit in the vaults of custodial exchanges and wallets.
For monetary liberty to be widespread it must be part of the social contract. We must come together to deploy decentralised systems that maintain Bitcoin's promise of sovereignty. These tools already exist and they are improving.

Awakening Our Inner Apex Predator

When Satoshi genetically engineered bitcoin, he spliced DNA from organisms that never survived (B-money, Hashcash, Bit gold). This gives bitcoin an incredible amount of survivability and fierceness. It makes it the apex predator of money.
Billions of dollars in cryptocurrency is traded, lent and borrowed on platforms that have self-custody and no KYC. Billions of dollars in cryptocurrency but not bitcoin. This decentralised financial system is called DeFi. Many Bitcoiners deny, ignore and attack DeFi because it is an invention, a mutation, that occurred on Ethereum. This reflexive defensiveness ignores a fundamental truth about Bitcoin: If any technology can provide value for Bitcoin, Bitcoin will simply adopt it. A nuanced view of DeFi recognises that it is composed both of valuable decentralisation but also of cancerous ponzis and evolutionary dead-ends. We will adopt DeFi where it improves Bitcoin DID (Defense-in-Depth) and cauterise the rest.

Defense-in-Depth

Bitcoin maintains its sovereignty through technological, cryptographic means. First and foremost, private keys provide the only means of control and ownership. Second, and most famously, Proof of Work defends the network against attack.
Attackers, however, are not limited to attacking the cryptography or the hashpower in order to limit our sovereignty. They route around and seek any weak links. "Trusted third parties are security holes". We increase the perimeter of defence by eliminating these trusted third parties.

Ethereum is Bitcoin’s Testnet

We will splice the DNA of DeFi into Bitcoin. We will increase Bitcoin's defense perimeter. The tools already exist. Ethereum is our testnet. Let it provide the radioactive pool where mutations are many. Let us observe it as it moves fast and breaks things. We will adopt it's best tools and learn to defend against its worst.
Rootstock, a Bitcoin sidechain, can be our CRISPR in this genetic adoption. We will splice the code from Ethereum dapps and improve upon them.

Cypherpunk Rouges

Cypherpunks write code, share code, review code and copy code. Sovereign individuals use this code. Like the X-men's Rouge, Bitcoiners will absorb the superpowers of others. I have been working on a DeFi dapp for decentralised bitcoin trading and lending. Hopefully you will join me, or better yet, compete with me.
"Those who would give up Liberty, to purchase a little temporary convenience, will have neither Liberty nor convenience." That will be our code.
Onwards.

Dragonchain Public Proposal TL;DR:

Dragonchain has demonstrated twice Reddit’s entire total daily volume (votes, comments, and posts per Reddit 2019 Year in Review) in a 24-hour demo on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. At the time, in January 2020, the entire cost of the demo was approximately $25K on a single system (transaction fees locked at $0.0001/txn). With current fees (lowest fee $0.0000025/txn), this would cost as little as $625.
Watch Joe walk through the entire proposal and answer questions on YouTube.
This proposal is also available on the Dragonchain blog.

Hello Reddit and Ethereum community!

I’m Joe Roets, Founder & CEO of Dragonchain. When the team and I first heard about The Great Reddit Scaling Bake-Off we were intrigued. We believe we have the solutions Reddit seeks for its community points system and we have them at scale.
For your consideration, we have submitted our proposal below. The team at Dragonchain and I welcome and look forward to your technical questions, philosophical feedback, and fair criticism, to build a scaling solution for Reddit that will empower its users. Because our architecture is unlike other blockchain platforms out there today, we expect to receive many questions while people try to grasp our project. I will answer all questions here in this thread on Reddit, and I've answered some questions in the stream on YouTube.
We have seen good discussions so far in the competition. We hope that Reddit’s scaling solution will emerge from The Great Reddit Scaling Bake-Off and that Reddit will have great success with the implementation.

Executive summary

Dragonchain is a robust open source hybrid blockchain platform that has proven to withstand the passing of time since our inception in 2014. We have continued to evolve to harness the scalability of private nodes, yet take full advantage of the security of public decentralized networks, like Ethereum. We have a live, operational, and fully functional Interchain network integrating Bitcoin, Ethereum, Ethereum Classic, and ~700 independent Dragonchain nodes. Every transaction is secured to Ethereum, Bitcoin, and Ethereum Classic. Transactions are immediately usable on chain, and the first decentralization is seen within 20 seconds on Dragon Net. Security increases further to public networks ETH, BTC, and ETC within 10 minutes to 2 hours. Smart contracts can be written in any executable language, offering full freedom to existing developers. We invite any developer to watch the demo, play with our SDK’s, review open source code, and to help us move forward. Dragonchain specializes in scalable loyalty & rewards solutions and has built a decentralized social network on chain, with very affordable transaction costs. This experience can be combined with the insights Reddit and the Ethereum community have gained in the past couple of months to roll out the solution at a rapid pace.

Response and PoC

In The Great Reddit Scaling Bake-Off post, Reddit has asked for a series of demonstrations, requirements, and other considerations. In this section, we will attempt to answer all of these requests.

Live Demo

A live proof of concept showing hundreds of thousands of transactions

On Jan 7, 2020, Dragonchain hosted a 24-hour live demonstration during which a quarter of a billion (250 million+) transactions executed fully on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. This means that every single transaction is secured by, and traceable to these networks. An attack on this system would require a simultaneous attack on all of the Interchained networks.
24 hours in 4 minutes (YouTube):
24 hours in 4 minutes
The demonstration was of a single business system, and any user is able to scale this further, by running multiple systems simultaneously. Our goals for the event were to demonstrate a consistent capacity greater than that of Visa over an extended time period.

Scaling

How it works & scales

Architectural Scaling

Dragonchain’s architecture attacks the scalability issue from multiple angles. Dragonchain is a hybrid blockchain platform, wherein every transaction is protected on a business node to the requirements of that business or purpose. A business node may be held completely private or may be exposed or replicated to any level of exposure desired.
Every node has its own blockchain and is independently scalable. Dragonchain established Context Based Verification as its consensus model. Every transaction is immediately usable on a trust basis, and in time is provable to an increasing level of decentralized consensus. A transaction will have a level of decentralization to independently owned and deployed Dragonchain nodes (~700 nodes) within seconds, and full decentralization to BTC and ETH within minutes or hours. Level 5 nodes (Interchain nodes) function to secure all transactions to public or otherwise external chains such as Bitcoin and Ethereum. These nodes scale the system by aggregating multiple blocks into a single Interchain transaction on a cadence. This timing is configurable based upon average fees for each respective chain. For detailed information about Dragonchain’s architecture, and Context Based Verification, please refer to the Dragonchain Architecture Document.

Economic Scaling

An interesting feature of Dragonchain’s network consensus is its economics and scarcity model. Since Dragon Net nodes (L2-L4) are independent staking nodes, deployment to cloud platforms would allow any of these nodes to scale to take on a large percentage of the verification work. This is great for scalability, but not good for the economy, because there is no scarcity, and pricing would develop a downward spiral and result in fewer verification nodes. For this reason, Dragonchain uses TIME as scarcity.
TIME is calculated as the number of Dragons held, multiplied by the number of days held. TIME influences the user’s access to features within the Dragonchain ecosystem. It takes into account both the Dragon balance and length of time each Dragon is held. TIME is staked by users against every verification node and dictates how much of the transaction fees are awarded to each participating node for every block.
TIME also dictates the transaction fee itself for the business node. TIME is staked against a business node to set a deterministic transaction fee level (see transaction fee table below in Cost section). This is very interesting in a discussion about scaling because it guarantees independence for business implementation. No matter how much traffic appears on the entire network, a business is guaranteed to not see an increased transaction fee rate.

Scaled Deployment

Dragonchain uses Docker and Kubernetes to allow the use of best practices traditional system scaling. Dragonchain offers managed nodes with an easy to use web based console interface. The user may also deploy a Dragonchain node within their own datacenter or favorite cloud platform. Users have deployed Dragonchain nodes on-prem on Amazon AWS, Google Cloud, MS Azure, and other hosting platforms around the world. Any executable code, anything you can write, can be written into a smart contract. This flexibility is what allows us to say that developers with no blockchain experience can use any code language to access the benefits of blockchain. Customers have used NodeJS, Python, Java, and even BASH shell script to write smart contracts on Dragonchain.
With Docker containers, we achieve better separation of concerns, faster deployment, higher reliability, and lower response times.
We chose Kubernetes for its self-healing features, ability to run multiple services on one server, and its large and thriving development community. It is resilient, scalable, and automated. OpenFaaS allows us to package smart contracts as Docker images for easy deployment.
Contract deployment time is now bounded only by the size of the Docker image being deployed but remains fast even for reasonably large images. We also take advantage of Docker’s flexibility and its ability to support any language that can run on x86 architecture. Any image, public or private, can be run as a smart contract using Dragonchain.

Flexibility in Scaling

Dragonchain’s architecture considers interoperability and integration as key features. From inception, we had a goal to increase adoption via integration with real business use cases and traditional systems.
We envision the ability for Reddit, in the future, to be able to integrate alternate content storage platforms or other financial services along with the token.

LBRY - To allow users to deploy content natively to LBRY
MakerDAO to allow users to lend small amounts backed by their Reddit community points.
STORJ/SIA to allow decentralized on chain storage of portions of content. These integrations or any other are relatively easy to integrate on Dragonchain with an Interchain implementation.

Cost

Cost estimates (on-chain and off-chain) For the purpose of this proposal, we assume that all transactions are on chain (posts, replies, and votes).

On the Dragonchain network, transaction costs are deterministic/predictable. By staking TIME on the business node (as described above) Reddit can reduce transaction costs to as low as $0.0000025 per transaction.

Getting Started

How to run it

Building on Dragonchain is simple and requires no blockchain experience. Spin up a business node (L1) in our managed environment (AWS), run it in your own cloud environment, or on-prem in your own datacenter. Clear documentation will walk you through the steps of spinning up your first Dragonchain Level 1 Business node.
Getting started is easy...

Download Dragonchain’s dctl
Input three commands into a terminal
Build an image
Run it

More information can be found in our Get started documents.

Architecture

Dragonchain is an open source hybrid platform. Through Dragon Net, each chain combines the power of a public blockchain (like Ethereum) with the privacy of a private blockchain.
Dragonchain organizes its network into five separate levels. A Level 1, or business node, is a totally private blockchain only accessible through the use of public/private keypairs. All business logic, including smart contracts, can be executed on this node directly and added to the chain.
After creating a block, the Level 1 business node broadcasts a version stripped of sensitive private data to Dragon Net. Three Level 2 Validating nodes validate the transaction based on guidelines determined from the business. A Level 3 Diversity node checks that the level 2 nodes are from a diverse array of locations. A Level 4 Notary node, hosted by a KYC partner, then signs the validation record received from the Level 3 node. The transaction hash is ledgered to the Level 5 public chain to take advantage of the hash power of massive public networks.
Dragon Net can be thought of as a “blockchain of blockchains”, where every level is a complete private blockchain. Because an L1 can send to multiple nodes on a single level, proof of existence is distributed among many places in the network. Eventually, proof of existence reaches level 5 and is published on a public network.

APIs (on chain & off)

SDK Source

Nobody’s Perfect

Known issues or tradeoffs

Dragonchain is open source and even though the platform is easy enough for developers to code in any language they are comfortable with, we do not have so large a developer community as Ethereum. We would like to see the Ethereum developer community (and any other communities) become familiar with our SDK’s, our solutions, and our platform, to unlock the full potential of our Ethereum Interchain. Long ago we decided to prioritize both Bitcoin and Ethereum Interchains. We envision an ecosystem that encompasses different projects to give developers the ability to take full advantage of all the opportunities blockchain offers to create decentralized solutions not only for Reddit but for all of our current platforms and systems. We believe that together we will take the adoption of blockchain further. We currently have additional Interchain with Ethereum Classic. We look forward to Interchain with other blockchains in the future. We invite all blockchains projects who believe in decentralization and security to Interchain with Dragonchain.
While we only have 700 nodes compared to 8,000 Ethereum and 10,000 Bitcoin nodes. We harness those 18,000 nodes to scale to extremely high levels of security. See Dragonchain metrics.
Some may consider the centralization of Dragonchain’s business nodes as an issue at first glance, however, the model is by design to protect business data. We do not consider this a drawback as these nodes can make any, none, or all data public. Depending upon the implementation, every subreddit could have control of its own business node, for potential business and enterprise offerings, bringing new alternative revenue streams to Reddit.

Costs and resources

Summary of cost & resource information for both on-chain & off-chain components used in the PoC, as well as cost & resource estimates for further scaling. If your PoC is not on mainnet, make note of any mainnet caveats (such as congestion issues).

Every transaction on the PoC system had a transaction fee of $0.0001 (one-hundredth of a cent USD). At 256MM transactions, the demo cost $25,600. With current operational fees, the same demonstration would cost $640 USD.
For the demonstration, to achieve throughput to mimic a worldwide payments network, we modeled several clients in AWS and 4-5 business nodes to handle the traffic. The business nodes were tuned to handle higher throughput by adjusting memory and machine footprint on AWS. This flexibility is valuable to implementing a system such as envisioned by Reddit. Given that Reddit’s daily traffic (posts, replies, and votes) is less than half that of our demo, we would expect that the entire Reddit system could be handled on 2-5 business nodes using right-sized containers on AWS or similar environments.
Verification was accomplished on the operational Dragon Net network with over 700 independently owned verification nodes running around the world at no cost to the business other than paid transaction fees.

Requirements

Scaling

This PoC should scale to the numbers below with minimal costs (both on & off-chain). There should also be a clear path to supporting hundreds of millions of users.
Over a 5 day period, your scaling PoC should be able to handle:
*100,000 point claims (minting & distributing points) *25,000 subscriptions *75,000 one-off points burning *100,000 transfers

During Dragonchain’s 24 hour demo, the above required numbers were reached within the first few minutes.
Reddit’s total activity is 9000% more than Ethereum’s total transaction level. Even if you do not include votes, it is still 700% more than Ethereum’s current volume. Dragonchain has demonstrated that it can handle 250 million transactions a day, and it’s architecture allows for multiple systems to work at that level simultaneously. In our PoC, we demonstrate double the full capacity of Reddit, and every transaction was proven all the way to Bitcoin and Ethereum.
Reddit Scaling on Ethereum

Decentralization

Solutions should not depend on any single third-party provider. We prefer solutions that do not depend on specific entities such as Reddit or another provider, and solutions with no single point of control or failure in off-chain components but recognize there are numerous trade-offs to consider

Dragonchain’s architecture calls for a hybrid approach. Private business nodes hold the sensitive data while the validation and verification of transactions for the business are decentralized within seconds and secured to public blockchains within 10 minutes to 2 hours. Nodes could potentially be controlled by owners of individual subreddits for more organic decentralization.

Billing is currently centralized - there is a path to federation and decentralization of a scaled billing solution.
Operational multi-cloud
Operational on-premises capabilities
Operational deployment to any datacenter
Over 700 independent Community Verification Nodes with proof of ownership
Operational Interchain (Interoperable to Bitcoin, Ethereum, and Ethereum Classic, open to more)

Usability Scaling solutions should have a simple end user experience.

Users shouldn't have to maintain any extra state/proofs, regularly monitor activity, keep track of extra keys, or sign anything other than their normal transactions

Dragonchain and its customers have demonstrated extraordinary usability as a feature in many applications, where users do not need to know that the system is backed by a live blockchain. Lyceum is one of these examples, where the progress of academy courses is being tracked, and successful completion of courses is rewarded with certificates on chain. Our @Save_The_Tweet bot is popular on Twitter. When used with one of the following hashtags - #please, #blockchain, #ThankYou, or #eternalize the tweet is saved through Eternal to multiple blockchains. A proof report is available for future reference. Other examples in use are DEN, our decentralized social media platform, and our console, where users can track their node rewards, view their TIME, and operate a business node.
Examples:

Transactions complete in a reasonable amount of time (seconds or minutes, not hours or days)

All transactions are immediately usable on chain by the system. A transaction begins the path to decentralization at the conclusion of a 5-second block when it gets distributed across 5 separate community run nodes. Full decentralization occurs within 10 minutes to 2 hours depending on which interchain (Bitcoin, Ethereum, or Ethereum Classic) the transaction hits first. Within approximately 2 hours, the combined hash power of all interchained blockchains secures the transaction.

Free to use for end users (no gas fees, or fixed/minimal fees that Reddit can pay on their behalf)

With transaction pricing as low as $0.0000025 per transaction, it may be considered reasonable for Reddit to cover transaction fees for users.
All of Reddit's Transactions on Blockchain (month)
Community points can be earned by users and distributed directly to their Reddit account in batch (as per Reddit minting plan), and allow users to withdraw rewards to their Ethereum wallet whenever they wish. Withdrawal fees can be paid by either user or Reddit. This model has been operating inside the Dragonchain system since 2018, and many security and financial compliance features can be optionally added. We feel that this capability greatly enhances user experience because it is seamless to a regular user without cryptocurrency experience, yet flexible to a tech savvy user. With regard to currency or token transactions, these would occur on the Reddit network, verified to BTC and ETH. These transactions would incur the $0.0000025 transaction fee. To estimate this fee we use the monthly active Reddit users statista with a 60% adoption rate and an estimated 10 transactions per month average resulting in an approximate $720 cost across the system. Reddit could feasibly incur all associated internal network charges (mining/minting, transfer, burn) as these are very low and controllable fees.
Reddit Internal Token Transaction Fees

Reddit Ethereum Token Transaction Fees
When we consider further the Ethereum fees that might be incurred, we have a few choices for a solution.

Offload all Ethereum transaction fees (user withdrawals) to interested users as they wish to withdraw tokens for external use or sale.
Cover Ethereum transaction fees by aggregating them on a timed schedule. Users would request withdrawal (from Reddit or individual subreddits), and they would be transacted on the Ethereum network every hour (or some other schedule).
In a combination of the above, customers could cover aggregated fees.
Integrate with alternate Ethereum roll up solutions or other proposals to aggregate minting and distribution transactions onto Ethereum.

Bonus Points

Users should be able to view their balances & transactions via a blockchain explorer-style interface

From interfaces for users who have no knowledge of blockchain technology to users who are well versed in blockchain terms such as those present in a typical block explorer, a system powered by Dragonchain has flexibility on how to provide balances and transaction data to users. Transactions can be made viewable in an Eternal Proof Report, which displays raw data along with TIME staking information and traceability all the way to Bitcoin, Ethereum, and every other Interchained network. The report shows fields such as transaction ID, timestamp, block ID, multiple verifications, and Interchain proof. See example here.
Node payouts within the Dragonchain console are listed in chronological order and can be further seen in either Dragons or USD. See example here.
In our social media platform, Dragon Den, users can see, in real-time, their NRG and MTR balances. See example here.
A new influencer app powered by Dragonchain, Raiinmaker, breaks down data into a user friendly interface that shows coin portfolio, redeemed rewards, and social scores per campaign. See example here.

Exiting is fast & simple

Withdrawing funds on Dragonchain’s console requires three clicks, however, withdrawal scenarios with more enhanced security features per Reddit’s discretion are obtainable.

Interoperability Compatibility with third party apps (wallets/contracts/etc) is necessary.

Proven interoperability at scale that surpasses the required specifications. Our entire platform consists of interoperable blockchains connected to each other and traditional systems. APIs are well documented. Third party permissions are possible with a simple smart contract without the end user being aware. No need to learn any specialized proprietary language. Any code base (not subsets) is usable within a Docker container. Interoperable with any blockchain or traditional APIs. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js. Please see our source code and API documentation.

Scaling solutions should be extensible and allow third parties to build on top of it Open source and extensible
APIs should be well documented and stable

Documentation should be clear and complete

For full documentation, explore our docs, SDK’s, Github repo’s, architecture documents, original Disney documentation, and other links or resources provided in this proposal.

Third-party permissionless integrations should be possible & straightforward Smart contracts are Docker based, can be written in any language, use full language (not subsets), and can therefore be integrated with any system including traditional system APIs. Simple is better. Learning an uncommon or proprietary language should not be necessary.

Advanced knowledge of mathematics, cryptography, or L2 scaling should not be required. Compatibility with common utilities & toolchains is expected.
Dragonchain business nodes and smart contracts leverage Docker to allow the use of literally any language or executable code. No proprietary language is necessary. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js.

Bonus

Bonus Points: Show us how it works. Do you have an idea for a cool new use case for Community Points? Build it!

TIME

Community points could be awarded to Reddit users based upon TIME too, whereas the longer someone is part of a subreddit, the more community points someone naturally gained, even if not actively commenting or sharing new posts. A daily login could be required for these community points to be credited. This grants awards to readers too and incentivizes readers to create an account on Reddit if they browse the website often. This concept could also be leveraged to provide some level of reputation based upon duration and consistency of contribution to a community subreddit.

Dragon Den

Dragonchain has already built a social media platform that harnesses community involvement. Dragon Den is a decentralized community built on the Dragonchain blockchain platform. Dragon Den is Dragonchain’s answer to fake news, trolling, and censorship. It incentivizes the creation and evaluation of quality content within communities. It could be described as being a shareholder of a subreddit or Reddit in its entirety. The more your subreddit is thriving, the more rewarding it will be. Den is currently in a public beta and in active development, though the real token economy is not live yet. There are different tokens for various purposes. Two tokens are Lair Ownership Rights (LOR) and Lair Ownership Tokens (LOT). LOT is a non-fungible token for ownership of a specific Lair. LOT will only be created and converted from LOR.
Energy (NRG) and Matter (MTR) work jointly. Your MTR determines how much NRG you receive in a 24-hour period. Providing quality content, or evaluating content will earn MTR.

Security. Users have full ownership & control of their points.

All community points awarded based upon any type of activity or gift, are secured and provable to all Interchain networks (currently BTC, ETH, ETC). Users are free to spend and withdraw their points as they please, depending on the features Reddit wants to bring into production.

Balances and transactions cannot be forged, manipulated, or blocked by Reddit or anyone else

Users can withdraw their balance to their ERC20 wallet, directly through Reddit. Reddit can cover the fees on their behalf, or the user covers this with a portion of their balance.

Users should own their points and be able to get on-chain ERC20 tokens without permission from anyone else

Through our console users can withdraw their ERC20 rewards. This can be achieved on Reddit too. Here is a walkthrough of our console, though this does not show the quick withdrawal functionality, a user can withdraw at any time. https://www.youtube.com/watch?v=aNlTMxnfVHw

Points should be recoverable to on-chain ERC20 tokens even if all third-parties involved go offline

If necessary, signed transactions from the Reddit system (e.g. Reddit + Subreddit) can be sent to the Ethereum smart contract for minting.

A public, third-party review attesting to the soundness of the design should be available

To our knowledge, at least two large corporations, including a top 3 accounting firm, have conducted positive reviews. These reviews have never been made public, as Dragonchain did not pay or contract for these studies to be released.

Bonus points
Public, third-party implementation review available or in progress

See above

Compatibility with HSMs & hardware wallets

For the purpose of this proposal, all tokenization would be on the Ethereum network using standard token contracts and as such, would be able to leverage all hardware wallet and Ethereum ecosystem services.

Other Considerations

Minting/distributing tokens is not performed by Reddit directly

This operation can be automated by smart contract on Ethereum. Subreddits can if desired have a role to play.

One off point burning, as well as recurring, non-interactive point burning (for subreddit memberships) should be possible and scalable

This is possible and scalable with interaction between Dragonchain Reddit system and Ethereum token contract(s).

Fully open-source solutions are strongly preferred

Dragonchain is fully open source (see section on Disney release after conclusion).

Conclusion

Whether it is today, or in the future, we would like to work together to bring secure flexibility to the highest standards. It is our hope to be considered by Ethereum, Reddit, and other integrative solutions so we may further discuss the possibilities of implementation. In our public demonstration, 256 million transactions were handled in our operational network on chain in 24 hours, for the low cost of $25K, which if run today would cost $625. Dragonchain’s interoperable foundation provides the atmosphere necessary to implement a frictionless community points system. Thank you for your consideration of our proposal. We look forward to working with the community to make something great!

Disney Releases Blockchain Platform as Open Source

The team at Disney created the Disney Private Blockchain Platform. The system was a hybrid interoperable blockchain platform for ledgering and smart contract development geared toward solving problems with blockchain adoption and usability. All objective evaluation would consider the team’s output a success. We released a list of use cases that we explored in some capacity at Disney, and our input on blockchain standardization as part of our participation in the W3C Blockchain Community Group.
https://lists.w3.org/Archives/Public/public-blockchain/2016May/0052.html

Open Source

In 2016, Roets proposed to release the platform as open source to spread the technology outside of Disney, as others within the W3C group were interested in the solutions that had been created inside of Disney.
Following a long process, step by step, the team met requirements for release. Among the requirements, the team had to:

Obtain VP support and approval for the release
Verify ownership of the software to be released
Verify that no proprietary content would be released
Convince the organization that there was a value to the open source community
Convince the organization that there was a value to Disney
Offer the plan for ongoing maintenance of the project outside of Disney
Itemize competing projects
Verify no conflict of interest
Preferred license
Change the project name to not use the name Disney, any Disney character, or any other associated IP - proposed Dragonchain - approved
Obtain legal approval
Approval from corporate, parks, and other business units
Approval from multiple Disney patent groups Copyright holder defined by Disney (Disney Connected and Advanced Technologies)
Trademark searches conducted for the selected name Dragonchain
Obtain IT security approval
Manual review of OSS components conducted
OWASP Dependency and Vulnerability Check Conducted
Obtain technical (software) approval
Offer management, process, and financial plans for the maintenance of the project.
Meet list of items to be addressed before release
Remove all Disney project references and scripts
Create a public distribution list for email communications
Remove Roets’ direct and internal contact information
Create public Slack channel and move from Disney slack channels
Create proper labels for issue tracking
Rename internal private Github repository
Add informative description to Github page
Expand README.md with more specific information
Add information beyond current “Blockchains are Magic”
Add getting started sections and info on cloning/forking the project
Add installation details
Add uninstall process
Add unit, functional, and integration test information
Detail how to contribute and get involved
Describe the git workflow that the project will use
Move to public, non-Disney git repository (Github or Bitbucket)
Obtain Disney Open Source Committee approval for release

On top of meeting the above criteria, as part of the process, the maintainer of the project had to receive the codebase on their own personal email and create accounts for maintenance (e.g. Github) with non-Disney accounts. Given the fact that the project spanned multiple business units, Roets was individually responsible for its ongoing maintenance. Because of this, he proposed in the open source application to create a non-profit organization to hold the IP and maintain the project. This was approved by Disney.
The Disney Open Source Committee approved the application known as OSSRELEASE-10, and the code was released on October 2, 2016. Disney decided to not issue a press release.

Taproot and Your /Coins

Taproot and Your Contracts

Taproot and Your Contracts, Part 2: Cryptographic Boogaloo

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 private 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.)

Quantum Quibbles!

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...)

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.

So:

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.

Summary

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!!

That's fine!

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!

For those missing the broadcast, Mr.XT has compiled the content for everyone~ Let’s get a review~
Host: Dyma Budorin | Hacken CEO
Guest: Weber WOO | XT.COM CEO
Dyma:Please introduce yourself a little.Where are you from?When were you involved in crypto?
Weber:Hello Hackeners. I am Weber Woo from the XT.COM exchange. I am glad to be invited here to share something about the XT exchange, XT team, and also myself. I am from Shanghai, China. When I was studying MBA at school in 2012, I read an article in Business Week about Bitcoin being very popular in Iran. Because of sanctions, many Iranians bought bitcoin to transfer their assets to overseas. That was the first time I heard about crypto.
Dyma:What experience do you have in crypto? Trading? Mining? Investing? Holding? Only positive experience or negative, too?
Weber:I will talk about my experience in Blockchain, and also my team.
In 2013, after my friends involved in Bitcoin, I also started to pay more attention to it. We began to mine Bitcoin.
From 2013-2016, we are more focused on mining and trading. We have 100,000 mining machines in our mining factory, located in Yunnan, Sichuan province in China. Of course, most of them are owned by our customers.
At the end of 2016, we started our mining pool business. Our mining portfolio included BTC, ETH, ETC, ZEC, SC, DCR. We had 5%of ETH computing power at the peak.
At the beginning of 2017, we invested a crypto exchange in China. But it was stopped in September 2017, because of China's new policies.
In the middle of 2018, we started the XT exchange in Seychelles, headquartered in HongKong.
Dyma:Have you ever been hacked?
Weber:I've never been hacked directly But lost my Bitcoin from the MT. Gox hack in 2014. That taught me a lot to keep crypto-assets safe.
The MT. Gox incident also reminded our team and me to take security measures very seriously when running the XT exchange.
Business
1.We know that XT has more than 1 millionn global users. You might have a big team. How many people? What idea does unite them?
Currently, XT has more than 80 employees comprised of the C-level team, technical developers, marketers, and business developers. More than 40% of our team have Postgraduate educational background. Our team comes from previous companies like Alibaba, Tencent, China Unicoin, Bosch, LG, and more.
Everyone on the team has a high level of understanding of what opportunities blockchain can and does provide for the world.
2.XT was introduced in 2018 — just in the beginning of crypto winter. Was it hard to start in such conditions? How did you motivate yourself and your colleagues?
Since XT started in a bear market, it was easier for us than other exchanges to stay agile and motivated.
We continued to grow our team and focus on building an exchange that protects its users and listens to what they want.
Understanding that just like any market, crypto goes through market cycles too. We stayed motivated and focused on being ready for the next bull market.
We already spend seven years in the blockchain industry. The bear market is an excellent opportunity to start a new business to save costs and talent recruits.
3.Is it really hard to be a Chinese crypto exchange nowadays?
As I said before, the XT exchange was registered in Seychelles, headquartered in HongKong. We are not officially a Chinese crypto exchange.
Half of our users are from other global markets than China. We are the most popular in Korea and Japan.
Of course, Crypto is still very popular in China, especially recently, with the rise of DeFi. Investors are smarter than 2017, but everyone is excited about all the new blockchain space developments.

4.Are your developers working on some new features? What should we expect?
Currently, XT is working on bringing new features to the exchange.
XT is the first social infused exchange that launched a Group Trading function in the BiYong App. BiYong is a social application focused on the Chinese market.
BiYong has more than 5 million users in total. We are the only partner for BiYong in Group trading. Users can trade within the social chatting app together as a collective.
I want to share some benefits for Group Trading.

This is how Group Trading typically works.

XT.com is launching a DEX.
We will launch DEX in quarter four this year. The product is still developing, so I cannot share more about it. We are glad to share it when it's ready.
Crypto future
1.Do you think the crypto winter is over?
With everything going on in the world currently, it is difficult to predict the future. I believe we are now in a bull market cycle, but things can change very quickly. We see different lengths of bear markets in the space as it grows. We must all pay attention to the trends and proceed accordingly.
2.Do you believe in the DeFi’s potential to make mass adoption closer? Why do you think it is so popular today?
The rise of DeFi has been incredible this year. Projects like LINK, UNI, YFI caught the attention of millions. The technology for real use cases has been implemented, and there is a real opportunity to get in on the ground floor for eager investors.
With the recent airdrop from Uniswap with their new token, UNI has only driven interest within the DeFi space. I believe it will take time, but DeFi is here to stay regardless if the market decides to cycle again.
We can see DeFi Locked Value in the past three years in the following pic. It's popular and here to stay.

3.What could you advise your users? What are the main risks in trading and investing today?
I advise anyone trading or investing in crypto to be smart.
The crypto market is a very volatile place. Using good risk management is critical to ensure the security of their funds.
Do not put all your eggs and one basket and only invest what you are willing to lose would be my recommendation, especially when it comes to altcoins.
I think that Bitcoin and Etheruem are the best low-risk long term investment options.
So I suggest you can divide your investment into 3 sections. For example, 40% in BTC and ETH, 30% for Top 50 altcoins, and 30% for HIGH risk projects if you are willing to take the risk.
We can see the risk from this picture.
https://preview.redd.it/8j9hvng5v8p51.png?width=753&format=png&auto=webp&s=e2ea47fa1cae0940e80048405d064d7726e6c6dc
4. What are your and your company long-term plans? Where will you be in 5 years?
Regarding the market, XT will continue to grow as we expand to more world markets like Europe, SE Asian, South Asian, and South America.
For compliance, we already had our MSB license approved in the US and will apply for more in different markets in the future.
On the business side, we will still focus on mining and the exchange. Of course, our CEX and DEX will be our primary focus in the years to come.

NewEnglandcoin
Symbol: NENG
NewEnglandcoin is a clone of Bitcoin using scrypt as a proof-of-work algorithm with enhanced features to protect against 51% attack and decentralize on mining to allow diversified mining rigs across CPUs, GPUs, ASICs and Android phones.
Mining Algorithm: Scrypt with RandomSpike. RandomSpike is 3rd generation of Dynamic Difficulty (DynDiff) algorithm on top of scrypt.
1 minute block targets base difficulty reset: every 1440 blocks subsidy halves in 2.1m blocks (~ 2 to 4 years) 84,000,000,000 total maximum NENG 20000 NENG per block Pre-mine: 1% - reserved for dev fund ICO: None RPCPort: 6376 Port: 6377
NewEnglandcoin has dogecoin like supply at 84 billion maximum NENG. This huge supply insures that NENG is suitable for retail transactions and daily use. The inflation schedule of NengEnglandcoin is actually identical to that of Litecoin. Bitcoin and Litecoin are already proven to be great long term store of value. The Litecoin-like NENG inflation schedule will make NewEnglandcoin ideal for long term investment appreciation as the supply is limited and capped at a fixed number
Bitcoin Fork - Suitable for Home Hobbyists
NewEnglandcoin core wallet continues to maintain version tag of "Satoshi v0.8.7.5" because NewEnglandcoin is very much an exact clone of bitcoin plus some mining feature changes with DynDiff algorithm. NewEnglandcoin is very suitable as lite version of bitcoin for educational purpose on desktop mining, full node running and bitcoin programming using bitcoin-json APIs.
The NewEnglandcoin (NENG) mining algorithm original upgrade ideas were mainly designed for decentralization of mining rigs on scrypt, which is same algo as litecoin/dogecoin. The way it is going now is that NENG is very suitable for bitcoin/litecoin/dogecoin hobbyists who can not , will not spend huge money to run noisy ASIC/GPU mining equipments, but still want to mine NENG at home with quiet simple CPU/GPU or with a cheap ASIC like FutureBit Moonlander 2 USB or Apollo pod on solo mining setup to obtain very decent profitable results. NENG allows bitcoin litecoin hobbyists to experience full node running, solo mining, CPU/GPU/ASIC for a fun experience at home at cheap cost without breaking bank on equipment or electricity.

CPU Minable Coin Because of dynamic difficulty algorithm on top of scrypt, NewEnglandcoin is CPU Minable. Users can easily set up full node for mining at Home PC or Mac using our dedicated cheetah software.
Research on the first forked 50 blocks on v1.2.0 core confirmed that ASIC/GPU miners mined 66% of 50 blocks, CPU miners mined the remaining 34%.
NENG v1.4.0 release enabled CPU mining inside android phones.

Decentralization and Community Driven NewEnglandcoin is a decentralized coin just like bitcoin. There is no boss on NewEnglandcoin. Nobody nor the dev owns NENG.
We know a coin is worth nothing if there is no backing from community. Therefore, we as dev do not intend to make decision on this coin solely by ourselves. It is our expectation that NewEnglandcoin community will make majority of decisions on direction of this coin from now on. We as dev merely view our-self as coin creater and technical support of this coin while providing NENG a permanent home at ShorelineCrypto Exchange.

ASIC/GPU Mining Pools Warning to Big ASIC Miners Due to DynDiff Algo on top of Scrypt, solo mining is recommended for ASIC/GPU miners. Further more, even for mining pools, small mining pool will generate better performance than big NENG mining pool because of new algo v1.2.x post hard fork.
The set up configuration of NENG for scrypt pool mining is same as a typical normal scrypt coin. In other word, DynDiff on Scrypt algo is backward compatible with Scrypt algo. Because ASIC/GPU miners rely on CPU miners for smooth blockchain movement, checkout bottom of "Latest News" section for A WARNING to All ASIC miners before you decide to dump big ASIC hash rate into NENG mining.
(1) Original DynDiff Warning: https://bitcointalk.org/index.php?topic=5027091.msg48324708#msg48324708 (2) New Warning on RandomSpike Spike difficulty (244k) introduced in RandomSpike served as roadblocks to instant mining and provide security against 51% attack risk. However, this spike difficulty like a roadblock that makes big ASIC mining less profitable. In case of spike block to be mined, the spike difficulty immediately serve as base difficulty, which will block GPU/ASIC miners effectively and leave CPU cheetah solo miners dominating mining almost 100% until next base difficulty reset.

2020 is the year of the outbreak of the DeFi market. As products of the DeFi 1.0 era, Maker, AAVE, and Compound have become the infrastructure of DeFI. Innovative projects of DeFi 2.0 represented by Uniswap and YFI have gradually attracted the attention of the market. Currently, DeFI 3.0 has emerged, technology innovation + business model innovation has become the theme of 3.0, and innovative projects represented by JDE have gradually occupied the market. This article focuses on the analysis of the JDE project and comprehensively evaluates the JDE project.
Project Positioning——A-
JDE is called Just for Decentralization. The project is positioned as a decentralized DeFi aggregator protocol. In the current DeFi market, each product is an independent agreement, providing users with independent products. For the user side, every DeFi project operation has a certain threshold. If a user selects multiple DeFi products at the same time, the complexity of the operation will be much higher. JDE's centralized decentralized protocol can better satisfy users' multi-faceted and full-ecological services. You can enjoy DeFi financial services with only one key operation.
Aggregation services are the most urgent needs of users in the current market. For example, similar to loan product AAVE, wealth management product Maker, insurance product NXM, etc., users must perform separate operations on each platform if they want to achieve their needs. The high threshold of DeFI will also prevent some users from entering this decentralized world.
JDE provides a complete protocol suite to allow users to perform fool-like one-key operations. On JDE's platform, it includes loan agreement, payment agreement, insurance agreement, decentralized transaction agreement and Game ecological agreement. Users can operate a variety of decentralized financial products on the protocol cluster. This positioning is very in line with the needs of current DeFi market users, and can serve millions of DeFi industry users to provide accurate services.
Project Technology-A
The DeFi project has high technical requirements. Each agreement is an independent individual, so a complete financial agreement aggregator has higher technical requirements. The technology of JDE has been developed for many years. JDE has created an on-chain and off-chain two-layer solution, which allows each protocol to be completed quickly in a short time, and the protocol cluster can also complete the interaction more quickly. Compared with other platforms, JDE's contract interaction time can be reduced by 60%. JDE's Layer 2 solution transfers transactions and transfers on the chain to off-chain, completes a Transaction off-chain, and then performs backup packaging on the chain. At the same time, JDE has added Aztec, a completely anonymous privacy protocol, which can provide more secure and anonymous services than Bitcoin. The following is the technical architecture diagram of JDE
JDE implements Full Stake DeFI on the technical side. As the basic ecological platform, JDE integrates mainstream products in the DeFi 1.0 and 2.0 eras, such as Maker, AAVE, BZX, Uniswap, Curve, YFI and other projects. It also provides projects based on ETH Full Stake DeFI, an independent solution, builds mainstream DeFi application components. Realize one end to meet all DeFi requirements.
JDE's protocol cluster will choose the most suitable product for users from mainstream products and products built by itself, make intelligent judgments between profitability and security, and then launch products that are most suitable for users. According to the needs of users, it will intelligently choose the products that best meet the users.
Each parameter in the JDE aggregation protocol will go through dozens of demonstrations to ensure that each parameter is in the safest state. JDE's technical teams are all from well-known companies around the world, and have a very deep technical foundation in the blockchain field. Compared with the technology of many DeFi projects on the market, the technical requirements of JDE are more complex. The technical aspect scored A.
Product solution——A+
JDE provides the safest guarantee for products at the bottom of the technology. Provides the most comprehensive and complete ecological services on the product side. JDE Ecology provides DeFI financial product solutions including asset pools, loan products, payment wallets, trading products DEX, insurance protection products, game products, etc.
Throughout the current DeFi financial products on the market, they can only provide a single product and service. But on the JDE platform, users can enjoy all aspects and the entire ecosystem of financial services. From the most basic asset pool for mining, lending to payment, to decentralized DEX platform transactions, insurance services, and game product services. Covers the various needs of mainstream users.
The product solution combines the various needs of the market. Focus on the asset pool JDE DAO Pool-V1. This is a more popular mining product today. In this product of JDE, users provide liquidity by depositing mainstream assets ETH, wBTC, USDT, etc., and can perform lending and DEX liquid pool transactions on the platform. Here the user's mortgage loan is a full mortgage, so the platform transplantation can be guaranteed to be in a safe state. When the user's mortgaged assets cannot cover the user's loaned assets, the platform will automatically liquidate. At this time, the platform will charge a 5% liquidation fee.
JDE Ecological DEX trading products are also the main source of revenue for the platform. The platform will charge a transaction fee of 0.2%, which is the lowest in the entire network. The handling fees of other platforms are above 0.3%. Users can inject liquidity into the DEX platform to become a market maker. The platform is very friendly to the project party, can list currency without review, and provide automated market services. The DEX trading platform can help the platform earn hundreds of thousands of dollars in handling fees (compared to the trading fee of the Uniswap platform).
JDE Eco provides a complete and multi-faceted product solution, and users can enjoy one-stop service. The product angle is rated A.
Economic Model-A
JDE is the first ecosystem in the entire network to successfully implement DAO governance. If you want to make product-related proposals in the JDE ecosystem, you must get the approval of the autonomous committee, which is composed of all currency holders. Each coin-holding user realizes a complete process of autonomy by voting on proposals. JDE's token, JDE, not only has appreciation rights, but also has very large autonomy rights.
Let's take a look at the JDE sub-token economy. The total amount of JDE is 10 million and will never be issued. Among them, 70% is used for community liquidity mining; 5% is owned by the technical team and locked for one year; 1% is for community private placement (20% is issued online, and 10% is released every week); 5% is an insurance pool; 10 % Is the DAO Autonomous Community Ecological Fund.
In the JDE economic model, almost 80% of the tokens are allocated to liquid mining, which is a very high proportion. Early rewards can be given to users who participate in the JDE community early. Users can get liquidity rewards for asset deposits, loans, DEX transactions, etc. in the JDE ecosystem. Only the technical section is allocated to the team, and the position is locked for long enough. 10% is the DAO autonomous community ecological fund, which participates in the DAO autonomous ecology. 5% is the insurance pool, which provides liquidity of funds. 1% is given to community welfare and allocated to users who participated in the early stage.
The profit of the products and services of JDE ecology will be repurchased in the JDE secondary market, which is always in a state of deflation. This economic model provides a long-term development guarantee for the JDE ecology. The economic model community surpasses most projects in the industry. The economic model is scored as A.
Comprehensive analysis, JDE ecology has a layout in the Defi field for many years, and at the same time has a very complete design in project positioning, product solutions, technological development, economic models and other sectors. The products in JDE's product solution will be gradually launched to provide users with the most complete ecological services. The prospects of the JDE project are good. It is currently in the early stages of project development. I look forward to the launch of JDE products to provide users with DeFi ecosystem services!
