Bitcoin - The Currency of the Internet

A community dedicated to Bitcoin, the currency of the Internet. Bitcoin is a distributed, worldwide, decentralized digital money. Bitcoins are issued and managed without any central authority whatsoever: there is no government, company, or bank in charge of Bitcoin. You might be interested in Bitcoin if you like cryptography, distributed peer-to-peer systems, or economics. A large percentage of Bitcoin enthusiasts are libertarians, though people of all political philosophies are welcome.

Technical: Taproot: Why Activate?

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.
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:
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:
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.
So:
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).

The danger when a majority of users is relying on SPV wallets (by belcher_)

This is a repost of a post by u/belcher_ on the bitcoin-dev mailinglist (source). I think it is a good description of why relying on SPV wallets (or someone else's node) can be dangerous for bitcoin from a "macro perspective. For clarification: SPV means "Simplified Payment Verification". In very simple words, it's a wallet that doesn't verify everything on the network (as opposed to what a full node does), and can be fooled in certain attack scenarios, as described below, f.ex.
For example, consider if bitcoin had 10000 users. 10 of them use a full node wallet while the other 9990 use an SPV wallet. If a miner attacked the system by printing infinite bitcoins and spending coins without a valid signature, then the 9990 SPV wallets would accept those fake coins as payment, and trade the coins amongst themselves. After a time those coins would likely be the ancestors of most active coins in the 9990-SPV-wallet ecosystem. Bitcoin would split into two currencies: full-node-coin and SPV-coin.
Now the fraud miners may become well known, perhaps being published on bitcoin news portals, but the 9990-SPV-wallet ecosystem has a strong incentive to be against any rollback. Their recent transactions would disappear and they'd lose money. They would argue that they've already been using the coin for a while, and it works perfectly fine, and anyway a coin that can be spent in 9990 places is more useful than one that can be spent in just 10 places. The SPV-wallet community might even decide to use something like invalidateblock to make sure their SPV-coin doesn't get reorg'd out of existence. There'd also likely be a social attack, with every bitcoin community portal being flooded with bots and shills advocating the merits of SPV-coin. This is not a hypothetical because we already saw the same thing during the scalability conflict 2015-2017.
Before you know it, "Bitcoin" would become SPV-coin with inflation and arbitrary seizure. Any normal user could download software called "Bitcoin wallet" which they trust and have used before, but instead of using Bitcoin they'd be using SPV-coin. You may be one of the 10 wallets backed by a full node, but that won't do much good to you when 9990 users happily use another coin as their medium of exchange.

Best Potential Moonshot Hands Down; TRUSTSWAP (SWAP) Full DeFi Suite, Simple P2P Trustless Escrow, and Great Tokenomics!

Trustswap https://www.coingecko.com/en/coins/trustswap
Okay guys I've spent the last two days learning about this token and I've come away very impressed. I think this token may be a serious contender for best performer this year. On the TrustSwap social platforms it feels like 2017. Here's some info about the company.
TrustSwap is a DeFi project created by the founder and CEO of Uptrennd Jeff Kirdeikis. Most notably he has the largest cryptocurrency investing group on Facebook, and he is what Tom was to MySpace but for Uptrennd. He host The Bitcoin and Crypto Podcast which is actually very good, and he has a massive following on Twitteother social. Better yet, this guy is a marketing genius like a less annoying Justin Sun. He has a pipeline of good news lined up and knows when and how to release that information on the masses. Everything he does seems meticulously thought through. He continually affirms his commitment to get SWAP listed on high volume exchanges with MXC yesterday, Hotbit today, and Houbi/Bitmax tomorrow he is actually succeeding. He is also very responsive and has team moderators standing by in the social media channels to field questions/vanquish FUD.
Here are the basics:
TrustSwap is building a DeFi ecosystem that will start out as a simple P2P trustless escrow and payment platform and evolve into a fully decentralized exchange (DEX) with leverage and futures options all offered via non-custodial smart contracts. They will also offer multi-chain token wrapping as a service and on-chain governance using the native ERC-20 token SWAP.
Imagine being able to wrap BTC, Monero, Digibyte, or any crypto and then trade it on uniswap, or have it interact with Ethereum compatible wallets, and applications.
Through this, you can move funds cross-chain without ever having to sign up to a Centralized Exchange, allowing you to never have to KYC, staying fully anonymous across exchanges.
Wrapping tokens also offers huge benefits to new blockchain projects that have their own chain, allowing them to save massively on listing fees, as well as instantly be connected to strong wallets and decentralized exchanges.
This puts the ability to trust back in the investor's hands and might spark a new ICO boom as new projects eager to establish credibility rush to use it. So yes beautiful wrapping everything layer 3 solution my brothren. And highly incentivised holding economics, for example rewarding users from fees collected from the DeFi network! And staking;
All fees paid to the platform will get split as follows:
80% goes back to holders as staking rewards
10% are burned forever (adding that value back to token holders)
10% goes to the dev fund which can be used as the community sees fit
This project has massive potential and is already building a strong community foundation with big moves coming soon as more exchanges and markets come on board. The staking and deflationary tokenomics make this a long term HODL for me.
Token Metrics:
Total Supply: 100,000,000 SWAP
Circulating Supply: 62,500,000 SWAP
Market Cap: $3.6 million
60,000,000 SWAP Initial liquidity offering on uniswap about two and half days ago, price dropped at like $0.035. Volume bottomed out and rising again (same with holder count).
20,000,000 Team Supply
20,000,000 Marketing, development, legal, bounties, OTC investors, airdrops.

Extra nugget from Jeff on Discord; "@everyone
SwapLogo SWAP is listing on Hotbit this Monday! SwapLogo https://hotbit.zendesk.com/hc/en-us/articles/360051689713
This is the first step into TrustSwap's emergence in the Asian markets. We are going to be kicking off major marketing campaigns with an Asian marketing firm within the coming week to follow up this listing.
We also have a couple more Top-50 listings lined up for this week as well
When we had a vote to see which exchange you wanted to see SWAP listed on, Huobi was the winner by a massive margin, so we will be opening up the conversation with Huobi to get SWAP listed on there also in the near future."
DYOR!! Godspeed! I'll see you guys on the other side!
To address FUD about OTC investors dumping, yes they are dumping, it's my belief most weak hands have exited the market, they got in at $0.005 per SWAP.

544 BTC were traded in Venezuela using LocalBitcoin (up from 394 BTC) last week, buying BTC with FIAT and selling BTC for FIAT. 544 BTC are 1,019,046,000,000 Bs. (Bolivares). One BTC is around 2,100,000,000 Bs. Monthly minimum wage is less than 5 USD (50,000 satoshis)

Hi guys,
Updating the numbers, the last week we were under 400 BTC first time in a long time. This week the volume recovered, so we are still at around 2,000 BTC monthly.
This is only measured using LocalBitcoin, there are other exchanges like AIRTM, Uphold, Binance and so on, but no open data). Most of the Localbitcoin trades are in Bolivares.
I recommend reading this website, it is one of the best english websites for Venezuela news (they sometimes touch the crypto and economic situation).

Yesterday a survey by a serious NGO was released sadly it is only in Spanish (it is called Encovi) they concluded the average income of the Venezuela is 0.72 USD daily.

Why i’m bullish on Zilliqa (long read)

Edit: TL;DR added in the comments
 
Hey all, I've been researching coins since 2017 and have gone through 100s of them in the last 3 years. I got introduced to blockchain via Bitcoin of course, analyzed Ethereum thereafter and from that moment I have a keen interest in smart contact platforms. I’m passionate about Ethereum but I find Zilliqa to have a better risk-reward ratio. Especially because Zilliqa has found an elegant balance between being secure, decentralized and scalable in my opinion.
 
Below I post my analysis of why from all the coins I went through I’m most bullish on Zilliqa (yes I went through Tezos, EOS, NEO, VeChain, Harmony, Algorand, Cardano etc.). Note that this is not investment advice and although it's a thorough analysis there is obviously some bias involved. Looking forward to what you all think!
 
Fun fact: the name Zilliqa is a play on ‘silica’ silicon dioxide which means “Silicon for the high-throughput consensus computer.”
 
This post is divided into (i) Technology, (ii) Business & Partnerships, and (iii) Marketing & Community. I’ve tried to make the technology part readable for a broad audience. If you’ve ever tried understanding the inner workings of Bitcoin and Ethereum you should be able to grasp most parts. Otherwise, just skim through and once you are zoning out head to the next part.
 
Technology and some more:
 
Introduction
 
The technology is one of the main reasons why I’m so bullish on Zilliqa. First thing you see on their website is: “Zilliqa is a high-performance, high-security blockchain platform for enterprises and next-generation applications.” These are some bold statements.
 
Before we deep dive into the technology let’s take a step back in time first as they have quite the history. The initial research paper from which Zilliqa originated dates back to August 2016: Elastico: A Secure Sharding Protocol For Open Blockchains where Loi Luu (Kyber Network) is one of the co-authors. Other ideas that led to the development of what Zilliqa has become today are: Bitcoin-NG, collective signing CoSi, ByzCoin and Omniledger.
 
The technical white paper was made public in August 2017 and since then they have achieved everything stated in the white paper and also created their own open source intermediate level smart contract language called Scilla (functional programming language similar to OCaml) too.
 
Mainnet is live since the end of January 2019 with daily transaction rates growing continuously. About a week ago mainnet reached 5 million transactions, 500.000+ addresses in total along with 2400 nodes keeping the network decentralized and secure. Circulating supply is nearing 11 billion and currently only mining rewards are left. The maximum supply is 21 billion with annual inflation being 7.13% currently and will only decrease with time.
 
Zilliqa realized early on that the usage of public cryptocurrencies and smart contracts were increasing but decentralized, secure, and scalable alternatives were lacking in the crypto space. They proposed to apply sharding onto a public smart contract blockchain where the transaction rate increases almost linear with the increase in the amount of nodes. More nodes = higher transaction throughput and increased decentralization. Sharding comes in many forms and Zilliqa uses network-, transaction- and computational sharding. Network sharding opens up the possibility of using transaction- and computational sharding on top. Zilliqa does not use state sharding for now. We’ll come back to this later.
 
Before we continue dissecting how Zilliqa achieves such from a technological standpoint it’s good to keep in mind that a blockchain being decentralised and secure and scalable is still one of the main hurdles in allowing widespread usage of decentralised networks. In my opinion this needs to be solved first before blockchains can get to the point where they can create and add large scale value. So I invite you to read the next section to grasp the underlying fundamentals. Because after all these premises need to be true otherwise there isn’t a fundamental case to be bullish on Zilliqa, right?
 
Down the rabbit hole
 
How have they achieved this? Let’s define the basics first: key players on Zilliqa are the users and the miners. A user is anybody who uses the blockchain to transfer funds or run smart contracts. Miners are the (shard) nodes in the network who run the consensus protocol and get rewarded for their service in Zillings (ZIL). The mining network is divided into several smaller networks called shards, which is also referred to as ‘network sharding’. Miners subsequently are randomly assigned to a shard by another set of miners called DS (Directory Service) nodes. The regular shards process transactions and the outputs of these shards are eventually combined by the DS shard as they reach consensus on the final state. More on how these DS shards reach consensus (via pBFT) will be explained later on.
 
The Zilliqa network produces two types of blocks: DS blocks and Tx blocks. One DS Block consists of 100 Tx Blocks. And as previously mentioned there are two types of nodes concerned with reaching consensus: shard nodes and DS nodes. Becoming a shard node or DS node is being defined by the result of a PoW cycle (Ethash) at the beginning of the DS Block. All candidate mining nodes compete with each other and run the PoW (Proof-of-Work) cycle for 60 seconds and the submissions achieving the highest difficulty will be allowed on the network. And to put it in perspective: the average difficulty for one DS node is ~ 2 Th/s equaling 2.000.000 Mh/s or 55 thousand+ GeForce GTX 1070 / 8 GB GPUs at 35.4 Mh/s. Each DS Block 10 new DS nodes are allowed. And a shard node needs to provide around 8.53 GH/s currently (around 240 GTX 1070s). Dual mining ETH/ETC and ZIL is possible and can be done via mining software such as Phoenix and Claymore. There are pools and if you have large amounts of hashing power (Ethash) available you could mine solo.
 
The PoW cycle of 60 seconds is a peak performance and acts as an entry ticket to the network. The entry ticket is called a sybil resistance mechanism and makes it incredibly hard for adversaries to spawn lots of identities and manipulate the network with these identities. And after every 100 Tx Blocks which corresponds to roughly 1,5 hour this PoW process repeats. In between these 1,5 hour, no PoW needs to be done meaning Zilliqa’s energy consumption to keep the network secure is low. For more detailed information on how mining works click here.
Okay, hats off to you. You have made it this far. Before we go any deeper down the rabbit hole we first must understand why Zilliqa goes through all of the above technicalities and understand a bit more what a blockchain on a more fundamental level is. Because the core of Zilliqa’s consensus protocol relies on the usage of pBFT (practical Byzantine Fault Tolerance) we need to know more about state machines and their function. Navigate to Viewblock, a Zilliqa block explorer, and just come back to this article. We will use this site to navigate through a few concepts.
 
We have established that Zilliqa is a public and distributed blockchain. Meaning that everyone with an internet connection can send ZILs, trigger smart contracts, etc. and there is no central authority who fully controls the network. Zilliqa and other public and distributed blockchains (like Bitcoin and Ethereum) can also be defined as state machines.
 
Taking the liberty of paraphrasing examples and definitions given by Samuel Brooks’ medium article, he describes the definition of a blockchain (like Zilliqa) as: “A peer-to-peer, append-only datastore that uses consensus to synchronize cryptographically-secure data”.
 
Next, he states that: "blockchains are fundamentally systems for managing valid state transitions”. For some more context, I recommend reading the whole medium article to get a better grasp of the definitions and understanding of state machines. Nevertheless, let’s try to simplify and compile it into a single paragraph. Take traffic lights as an example: all its states (red, amber, and green) are predefined, all possible outcomes are known and it doesn’t matter if you encounter the traffic light today or tomorrow. It will still behave the same. Managing the states of a traffic light can be done by triggering a sensor on the road or pushing a button resulting in one traffic lights’ state going from green to red (via amber) and another light from red to green.
 
With public blockchains like Zilliqa, this isn’t so straightforward and simple. It started with block #1 almost 1,5 years ago and every 45 seconds or so a new block linked to the previous block is being added. Resulting in a chain of blocks with transactions in it that everyone can verify from block #1 to the current #647.000+ block. The state is ever changing and the states it can find itself in are infinite. And while the traffic light might work together in tandem with various other traffic lights, it’s rather insignificant comparing it to a public blockchain. Because Zilliqa consists of 2400 nodes who need to work together to achieve consensus on what the latest valid state is while some of these nodes may have latency or broadcast issues, drop offline or are deliberately trying to attack the network, etc.
 
Now go back to the Viewblock page take a look at the amount of transaction, addresses, block and DS height and then hit refresh. Obviously as expected you see new incremented values on one or all parameters. And how did the Zilliqa blockchain manage to transition from a previous valid state to the latest valid state? By using pBFT to reach consensus on the latest valid state.
 
After having obtained the entry ticket, miners execute pBFT to reach consensus on the ever-changing state of the blockchain. pBFT requires a series of network communication between nodes, and as such there is no GPU involved (but CPU). Resulting in the total energy consumed to keep the blockchain secure, decentralized and scalable being low.
 
pBFT stands for practical Byzantine Fault Tolerance and is an optimization on the Byzantine Fault Tolerant algorithm. To quote Blockonomi: “In the context of distributed systems, Byzantine Fault Tolerance is the ability of a distributed computer network to function as desired and correctly reach a sufficient consensus despite malicious components (nodes) of the system failing or propagating incorrect information to other peers.” Zilliqa is such a distributed computer network and depends on the honesty of the nodes (shard and DS) to reach consensus and to continuously update the state with the latest block. If pBFT is a new term for you I can highly recommend the Blockonomi article.
 
The idea of pBFT was introduced in 1999 - one of the authors even won a Turing award for it - and it is well researched and applied in various blockchains and distributed systems nowadays. If you want more advanced information than the Blockonomi link provides click here. And if you’re in between Blockonomi and the University of Singapore read the Zilliqa Design Story Part 2 dating from October 2017.
Quoting from the Zilliqa tech whitepaper: “pBFT relies upon a correct leader (which is randomly selected) to begin each phase and proceed when the sufficient majority exists. In case the leader is byzantine it can stall the entire consensus protocol. To address this challenge, pBFT offers a view change protocol to replace the byzantine leader with another one.”
 
pBFT can tolerate ⅓ of the nodes being dishonest (offline counts as Byzantine = dishonest) and the consensus protocol will function without stalling or hiccups. Once there are more than ⅓ of dishonest nodes but no more than ⅔ the network will be stalled and a view change will be triggered to elect a new DS leader. Only when more than ⅔ of the nodes are dishonest (66%) double-spend attacks become possible.
 
If the network stalls no transactions can be processed and one has to wait until a new honest leader has been elected. When the mainnet was just launched and in its early phases, view changes happened regularly. As of today the last stalling of the network - and view change being triggered - was at the end of October 2019.
 
Another benefit of using pBFT for consensus besides low energy is the immediate finality it provides. Once your transaction is included in a block and the block is added to the chain it’s done. Lastly, take a look at this article where three types of finality are being defined: probabilistic, absolute and economic finality. Zilliqa falls under the absolute finality (just like Tendermint for example). Although lengthy already we skipped through some of the inner workings from Zilliqa’s consensus: read the Zilliqa Design Story Part 3 and you will be close to having a complete picture on it. Enough about PoW, sybil resistance mechanism, pBFT, etc. Another thing we haven’t looked at yet is the amount of decentralization.
 
Decentralisation
 
Currently, there are four shards, each one of them consisting of 600 nodes. 1 shard with 600 so-called DS nodes (Directory Service - they need to achieve a higher difficulty than shard nodes) and 1800 shard nodes of which 250 are shard guards (centralized nodes controlled by the team). The amount of shard guards has been steadily declining from 1200 in January 2019 to 250 as of May 2020. On the Viewblock statistics, you can see that many of the nodes are being located in the US but those are only the (CPU parts of the) shard nodes who perform pBFT. There is no data from where the PoW sources are coming. And when the Zilliqa blockchain starts reaching its transaction capacity limit, a network upgrade needs to be executed to lift the current cap of maximum 2400 nodes to allow more nodes and formation of more shards which will allow to network to keep on scaling according to demand.
Besides shard nodes there are also seed nodes. The main role of seed nodes is to serve as direct access points (for end-users and clients) to the core Zilliqa network that validates transactions. Seed nodes consolidate transaction requests and forward these to the lookup nodes (another type of nodes) for distribution to the shards in the network. Seed nodes also maintain the entire transaction history and the global state of the blockchain which is needed to provide services such as block explorers. Seed nodes in the Zilliqa network are comparable to Infura on Ethereum.
 
The seed nodes were first only operated by Zilliqa themselves, exchanges and Viewblock. Operators of seed nodes like exchanges had no incentive to open them for the greater public. They were centralised at first. Decentralisation at the seed nodes level has been steadily rolled out since March 2020 ( Zilliqa Improvement Proposal 3 ). Currently the amount of seed nodes is being increased, they are public-facing and at the same time PoS is applied to incentivize seed node operators and make it possible for ZIL holders to stake and earn passive yields. Important distinction: seed nodes are not involved with consensus! That is still PoW as entry ticket and pBFT for the actual consensus.
 
5% of the block rewards are being assigned to seed nodes (from the beginning in 2019) and those are being used to pay out ZIL stakers. The 5% block rewards with an annual yield of 10.03% translate to roughly 610 MM ZILs in total that can be staked. Exchanges use the custodial variant of staking and wallets like Moonlet will use the non-custodial version (starting in Q3 2020). Staking is being done by sending ZILs to a smart contract created by Zilliqa and audited by Quantstamp.
 
With a high amount of DS; shard nodes and seed nodes becoming more decentralized too, Zilliqa qualifies for the label of decentralized in my opinion.
 
Smart contracts
 
Let me start by saying I’m not a developer and my programming skills are quite limited. So I‘m taking the ELI5 route (maybe 12) but if you are familiar with Javascript, Solidity or specifically OCaml please head straight to Scilla - read the docs to get a good initial grasp of how Zilliqa’s smart contract language Scilla works and if you ask yourself “why another programming language?” check this article. And if you want to play around with some sample contracts in an IDE click here. The faucet can be found here. And more information on architecture, dapp development and API can be found on the Developer Portal.
If you are more into listening and watching: check this recent webinar explaining Zilliqa and Scilla. Link is time-stamped so you’ll start right away with a platform introduction, roadmap 2020 and afterwards a proper Scilla introduction.
 
Generalized: programming languages can be divided into being ‘object-oriented’ or ‘functional’. Here is an ELI5 given by software development academy: * “all programs have two basic components, data – what the program knows – and behavior – what the program can do with that data. So object-oriented programming states that combining data and related behaviors in one place, is called “object”, which makes it easier to understand how a particular program works. On the other hand, functional programming argues that data and behavior are different things and should be separated to ensure their clarity.” *
 
Scilla is on the functional side and shares similarities with OCaml: OCaml is a general-purpose programming language with an emphasis on expressiveness and safety. It has an advanced type system that helps catch your mistakes without getting in your way. It's used in environments where a single mistake can cost millions and speed matters, is supported by an active community, and has a rich set of libraries and development tools. For all its power, OCaml is also pretty simple, which is one reason it's often used as a teaching language.
 
Scilla is blockchain agnostic, can be implemented onto other blockchains as well, is recognized by academics and won a so-called Distinguished Artifact Award award at the end of last year.
 
One of the reasons why the Zilliqa team decided to create their own programming language focused on preventing smart contract vulnerabilities is that adding logic on a blockchain, programming, means that you cannot afford to make mistakes. Otherwise, it could cost you. It’s all great and fun blockchains being immutable but updating your code because you found a bug isn’t the same as with a regular web application for example. And with smart contracts, it inherently involves cryptocurrencies in some form thus value.
 
Another difference with programming languages on a blockchain is gas. Every transaction you do on a smart contract platform like Zilliqa or Ethereum costs gas. With gas you basically pay for computational costs. Sending a ZIL from address A to address B costs 0.001 ZIL currently. Smart contracts are more complex, often involve various functions and require more gas (if gas is a new concept click here ).
 
So with Scilla, similar to Solidity, you need to make sure that “every function in your smart contract will run as expected without hitting gas limits. An improper resource analysis may lead to situations where funds may get stuck simply because a part of the smart contract code cannot be executed due to gas limits. Such constraints are not present in traditional software systems”. Scilla design story part 1
 
Some examples of smart contract issues you’d want to avoid are: leaking funds, ‘unexpected changes to critical state variables’ (example: someone other than you setting his or her address as the owner of the smart contract after creation) or simply killing a contract.
 
Scilla also allows for formal verification. Wikipedia to the rescue: In the context of hardware and software systems, formal verification is the act of proving or disproving the correctness of intended algorithms underlying a system with respect to a certain formal specification or property, using formal methods of mathematics.
 
Formal verification can be helpful in proving the correctness of systems such as: cryptographic protocols, combinational circuits, digital circuits with internal memory, and software expressed as source code.
 
Scilla is being developed hand-in-hand with formalization of its semantics and its embedding into the Coq proof assistant — a state-of-the art tool for mechanized proofs about properties of programs.”
 
Simply put, with Scilla and accompanying tooling developers can be mathematically sure and proof that the smart contract they’ve written does what he or she intends it to do.
 
Smart contract on a sharded environment and state sharding
 
There is one more topic I’d like to touch on: smart contract execution in a sharded environment (and what is the effect of state sharding). This is a complex topic. I’m not able to explain it any easier than what is posted here. But I will try to compress the post into something easy to digest.
 
Earlier on we have established that Zilliqa can process transactions in parallel due to network sharding. This is where the linear scalability comes from. We can define simple transactions: a transaction from address A to B (Category 1), a transaction where a user interacts with one smart contract (Category 2) and the most complex ones where triggering a transaction results in multiple smart contracts being involved (Category 3). The shards are able to process transactions on their own without interference of the other shards. With Category 1 transactions that is doable, with Category 2 transactions sometimes if that address is in the same shard as the smart contract but with Category 3 you definitely need communication between the shards. Solving that requires to make a set of communication rules the protocol needs to follow in order to process all transactions in a generalised fashion.
 
And this is where the downsides of state sharding comes in currently. All shards in Zilliqa have access to the complete state. Yes the state size (0.1 GB at the moment) grows and all of the nodes need to store it but it also means that they don’t need to shop around for information available on other shards. Requiring more communication and adding more complexity.

Roadmap / Zilliqa 2.0
 
There is no strict defined roadmap but here are topics being worked on. And via the Zilliqa website there is also more information on the projects they are working on.
 
Business & Partnerships
 
It’s not only technology in which Zilliqa seems to be excelling as their ecosystem has been expanding and starting to grow rapidly. The project is on a mission to provide OpenFinance (OpFi) to the world and Singapore is the right place to be due to its progressive regulations and futuristic thinking. Singapore has taken a proactive approach towards cryptocurrencies by introducing the Payment Services Act 2019 (PS Act). Among other things, the PS Act will regulate intermediaries dealing with certain cryptocurrencies, with a particular focus on consumer protection and anti-money laundering. It will also provide a stable regulatory licensing and operating framework for cryptocurrency entities, effectively covering all crypto businesses and exchanges based in Singapore. According to PWC 82% of the surveyed executives in Singapore reported blockchain initiatives underway and 13% of them have already brought the initiatives live to the market. There is also an increasing list of organizations that are starting to provide digital payment services. Moreover, Singaporean blockchain developers Building Cities Beyond has recently created an innovation $15 million grant to encourage development on its ecosystem. This all suggests that Singapore tries to position itself as (one of) the leading blockchain hubs in the world.
 
Zilliqa seems to already take advantage of this and recently helped launch Hg Exchange on their platform, together with financial institutions PhillipCapital, PrimePartners and Fundnel. Hg Exchange, which is now approved by the Monetary Authority of Singapore (MAS), uses smart contracts to represent digital assets. Through Hg Exchange financial institutions worldwide can use Zilliqa's safe-by-design smart contracts to enable the trading of private equities. For example, think of companies such as Grab, Airbnb, SpaceX that are not available for public trading right now. Hg Exchange will allow investors to buy shares of private companies & unicorns and capture their value before an IPO. Anquan, the main company behind Zilliqa, has also recently announced that they became a partner and shareholder in TEN31 Bank, which is a fully regulated bank allowing for tokenization of assets and is aiming to bridge the gap between conventional banking and the blockchain world. If STOs, the tokenization of assets, and equity trading will continue to increase, then Zilliqa’s public blockchain would be the ideal candidate due to its strategic positioning, partnerships, regulatory compliance and the technology that is being built on top of it.
 
What is also very encouraging is their focus on banking the un(der)banked. They are launching a stablecoin basket starting with XSGD. As many of you know, stablecoins are currently mostly used for trading. However, Zilliqa is actively trying to broaden the use case of stablecoins. I recommend everybody to read this text that Amrit Kumar wrote (one of the co-founders). These stablecoins will be integrated in the traditional markets and bridge the gap between the crypto world and the traditional world. This could potentially revolutionize and legitimise the crypto space if retailers and companies will for example start to use stablecoins for payments or remittances, instead of it solely being used for trading.
 
Zilliqa also released their DeFi strategic roadmap (dating November 2019) which seems to be aligning well with their OpFi strategy. A non-custodial DEX is coming to Zilliqa made by Switcheo which allows cross-chain trading (atomic swaps) between ETH, EOS and ZIL based tokens. They also signed a Memorandum of Understanding for a (soon to be announced) USD stablecoin. And as Zilliqa is all about regulations and being compliant, I’m speculating on it to be a regulated USD stablecoin. Furthermore, XSGD is already created and visible on block explorer and XIDR (Indonesian Stablecoin) is also coming soon via StraitsX. Here also an overview of the Tech Stack for Financial Applications from September 2019. Further quoting Amrit Kumar on this:
 
There are two basic building blocks in DeFi/OpFi though: 1) stablecoins as you need a non-volatile currency to get access to this market and 2) a dex to be able to trade all these financial assets. The rest are built on top of these blocks.
 
So far, together with our partners and community, we have worked on developing these building blocks with XSGD as a stablecoin. We are working on bringing a USD-backed stablecoin as well. We will soon have a decentralised exchange developed by Switcheo. And with HGX going live, we are also venturing into the tokenization space. More to come in the future.”
 
Additionally, they also have this ZILHive initiative that injects capital into projects. There have been already 6 waves of various teams working on infrastructure, innovation and research, and they are not from ASEAN or Singapore only but global: see Grantees breakdown by country. Over 60 project teams from over 20 countries have contributed to Zilliqa's ecosystem. This includes individuals and teams developing wallets, explorers, developer toolkits, smart contract testing frameworks, dapps, etc. As some of you may know, Unstoppable Domains (UD) blew up when they launched on Zilliqa. UD aims to replace cryptocurrency addresses with a human-readable name and allows for uncensorable websites. Zilliqa will probably be the only one able to handle all these transactions onchain due to ability to scale and its resulting low fees which is why the UD team launched this on Zilliqa in the first place. Furthermore, Zilliqa also has a strong emphasis on security, compliance, and privacy, which is why they partnered with companies like Elliptic, ChainSecurity (part of PwC Switzerland), and Incognito. Their sister company Aqilliz (Zilliqa spelled backwards) focuses on revolutionizing the digital advertising space and is doing interesting things like using Zilliqa to track outdoor digital ads with companies like Foodpanda.
 
Zilliqa is listed on nearly all major exchanges, having several different fiat-gateways and recently have been added to Binance’s margin trading and futures trading with really good volume. They also have a very impressive team with good credentials and experience. They don't just have “tech people”. They have a mix of tech people, business people, marketeers, scientists, and more. Naturally, it's good to have a mix of people with different skill sets if you work in the crypto space.
 
Marketing & Community
 
Zilliqa has a very strong community. If you just follow their Twitter their engagement is much higher for a coin that has approximately 80k followers. They also have been ‘coin of the day’ by LunarCrush many times. LunarCrush tracks real-time cryptocurrency value and social data. According to their data, it seems Zilliqa has a more fundamental and deeper understanding of marketing and community engagement than almost all other coins. While almost all coins have been a bit frozen in the last months, Zilliqa seems to be on its own bull run. It was somewhere in the 100s a few months ago and is currently ranked #46 on CoinGecko. Their official Telegram also has over 20k people and is very active, and their community channel which is over 7k now is more active and larger than many other official channels. Their local communities also seem to be growing.
 
Moreover, their community started ‘Zillacracy’ together with the Zilliqa core team ( see www.zillacracy.com ). It’s a community-run initiative where people from all over the world are now helping with marketing and development on Zilliqa. Since its launch in February 2020 they have been doing a lot and will also run their own non-custodial seed node for staking. This seed node will also allow them to start generating revenue for them to become a self sustaining entity that could potentially scale up to become a decentralized company working in parallel with the Zilliqa core team. Comparing it to all the other smart contract platforms (e.g. Cardano, EOS, Tezos etc.) they don't seem to have started a similar initiative (correct me if I’m wrong though). This suggests in my opinion that these other smart contract platforms do not fully understand how to utilize the ‘power of the community’. This is something you cannot ‘buy with money’ and gives many projects in the space a disadvantage.
 
Zilliqa also released two social products called SocialPay and Zeeves. SocialPay allows users to earn ZILs while tweeting with a specific hashtag. They have recently used it in partnership with the Singapore Red Cross for a marketing campaign after their initial pilot program. It seems like a very valuable social product with a good use case. I can see a lot of traditional companies entering the space through this product, which they seem to suggest will happen. Tokenizing hashtags with smart contracts to get network effect is a very smart and innovative idea.
 
Regarding Zeeves, this is a tipping bot for Telegram. They already have 1000s of signups and they plan to keep upgrading it for more and more people to use it (e.g. they recently have added a quiz features). They also use it during AMAs to reward people in real-time. It’s a very smart approach to grow their communities and get familiar with ZIL. I can see this becoming very big on Telegram. This tool suggests, again, that the Zilliqa team has a deeper understanding of what the crypto space and community needs and is good at finding the right innovative tools to grow and scale.
 
To be honest, I haven’t covered everything (i’m also reaching the character limited haha). So many updates happening lately that it's hard to keep up, such as the International Monetary Fund mentioning Zilliqa in their report, custodial and non-custodial Staking, Binance Margin, Futures, Widget, entering the Indian market, and more. The Head of Marketing Colin Miles has also released this as an overview of what is coming next. And last but not least, Vitalik Buterin has been mentioning Zilliqa lately acknowledging Zilliqa and mentioning that both projects have a lot of room to grow. There is much more info of course and a good part of it has been served to you on a silver platter. I invite you to continue researching by yourself :-) And if you have any comments or questions please post here!

[ Bitcoin ] Technical: Taproot: Why Activate?

Topic originally posted in Bitcoin by almkglor [link]
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.
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:
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:
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.
So:
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).

Bad Architecture, part 3, digging deeper...

Part 1 Part 2
I'm at $BigClient, which is taking a Citroen like approach to infrastructure and operations. "We recognize that the McPherson strut is simple, efficient, good enough for most use cases and accepted by everyone in the industry, but we shall do it with hydraulic fluid at high pressure. What could go wrong?"
Except $BigClient's far away from a competent Citroen shop. $BigClient's Citroen has gone through a few years of 'just keep it running on the cheap' upkeep without access to factory parts.
I've got an odd patching problem on a handful of servers. Systems are rolling back to insecure versions (2.0.2 ->1.4.6) and nobody knows why.
Or at least, nobody's talking.
I don't know what to do yet, so I decide to go and get lunch. I work out the possibilities.
  1. There's something wrong with our validation procedure- they're actually patched and we're reading the wrong thing.
  2. There's something or someone else downgrading these systems.
Number 1 requires more documentation, which $BC doesn't seem to want to show me. Number two might be hiding in logs, which are emailed to me on a regular basis.
I walk back to my cubicle, grab my laptop and a notebook and find a quiet corner to figure things out. I find one in a tiny conference room.
I read through my emails and search for any of the logs from the api servers.
I spend about ten minutes on Stack Exchange for the appropriate sed, awk, tee and cat munging to pare them down to what I want. Eventually I dump them all to Excel, because I am a bad person.
Some filtering and I can see what's going on. The system orchestration updates each server every other midnight. I see about three quarters of them download the 2.0.2 version as a part of the night's update.
Every two nights a (seemingly) random selection of servers updates. I scribble the order on the conference room whiteboard and stare at them for a few minutes.
Nothing in the orchestration system logs shows another process loading the older 1.4.6. version. But something is.
Nothing in the logs emailed to me obviously points to another process.
I take a walk to get a coffee and think. Nothing comes to me and I have to scour the kitchen for unflavored coffee. I walk back to my conference room to find an intern-like person.
me:"Hey, I apologize. I didn't know the room was reserved. I'll take my stuff."
Other person:"That's ok. Are you Rob?"
me:"Nope, sorry"
I take my stuff and make my way back to my cubicle.
A few minutes searching leads me to a shared root password for the servers stored in the password vault.
I login to one of the remaining servers running 2.0.2 and look at the running processes. Nothing obvious like "random updater".
I'm stumped.
I lean back and stare at nothing in particular trying to come up with some ideas.
Unfortunately, it's fairly packed and I'm next to a bullpen.
Voice 1:"So the Sky Caps put blotter in the vat without telling anyone"
Voice 2:"Hilton Honors kicks' Marriott Bonvoy's ass any day."
Voice 3:"No, I'll pick her up at 4"
The voices wash over me in some clip reel workplace sitcom haze. I'm not going to get anything done. I take a walk around the offices to get the lay of the land. It's a Hanna-Barbera cartoon of grey cubefarms, tan breakrooms, free coffee but no snacks. The only attempts at color are people's cubicles. Family pictures, shirtless men with fish, desk toys and action figures. It's like a mall- everything's pleasant, non threatening and in identically-sized stalls, with colorful (but bounded) individuality, all for commerce.
Then I find the Hot Topic meets Successories manifesting in a cubicle. There are two dorm-room sized posters of the gold Bitcoin-coin, along with framed inspirational quotes about success and perserverance set against pictures of Game Of Thrones characters and muscle-bound men in insignia-less camo. A new leather jacket with an embroidered skull is on the back of the chair. This person is either a hoot or insufferable.
I keep walking. I have a breakthrough.
Where are the API servers getting the older version to install? Maybe that'll lead me into the library. I'm not yet Adso, but perhaps I'm one of the other ,lesser scribes copying my book and scribbling fanciful drawings of the things I miss, like decent coffee and a cell-mate that doesn't snore.
I walk back to my cubicle. A different intern-shaped person is in the conference room, all alone.
I can't save them. Eventually they'll be standing in the corner of their cubicle looking away while the middle manager cleans out the rest of their team.
I'm in my seat. Some searching results in a few possible repositories. Some more searching finds me the one repo that still has v1.4.6 of this application.
Just to make sure, I compare a downloaded copy of v1.4.6 and the installed version of v 1.4.6 on one of the servers.
I search all the folders and files for the URL of the repo server and find it.
In the application itself. The server waits every two days and looks to the repo. If the installed version is not equal to v 1.4.6, it downloads v 1.4.6 from the server and installs it, then forces a restart.
This code is commented out (made non-executable) along with an actual comment:
/REMOVE BEFORE PRODUCTION
I quickly scan through the API servers to find one of the ones still running 2.0.2. I search for the term "REMOVE BEFORE PRODUCTION"
And there it is, in the application code.
Except it's not commented out.
In a text editor, I write up my findings, conclusion and a recommended fix- delete the upgrade code snippet, increment to 2.0.3, push it out using the orchestration tool and call it a day.
LC Chat won't let me attach my text file, so I breathlessly LC Chat my document, line by line at Vincent, the poor bastard tasked with closing audit finding 162, the mystery of the random rollback.
Vincent:...
Clearly, Vincent is choosing his congratulatory language carefully.
Vincent:"Can't apply the fix. The application is owned by Development. They're behind on other things, so they won't update the software until next quarter."
me:"It's about thirty lines of code we can comment out"
Vincent:"Can we say it's fixed for the audit since we know what the problem is?"
me:"No. We can patch it, or we could write up a remediation plan and get it on some schedule."
me:"But that's more paperwork than the actual fix."
Vincent:"But Ops isn't on good terms with Development."
me:"So they're not going to touch it any time soon."
Vincent:"Probably not"
me:You guys own that repo server, too"
Vincent:"I don't see how that's good for anything"
me:"We cut out the update code in 2.0.2 and call it 2.0.3. We name the file 1.4.6 and replace the existing 1.4.6 on the repo server. Either the app gets updated via your orchestration server or it updates itself. We're fixed in two days either way.
Vincent:"But policy requires that we get approval"
me:"There's an exception, if you have a superior in Operations to sign off, you can call it an emergency fix. Ask Trevor. He just needs to not tell anyone else. You submit the ticket and eventually the devs will get to it and fix the problem for good. Until then, you pass that part of the audit."
Vincent tells me he's going to talk to Trevor. I'm going to take a walk. Out of curiosity, I go back to the Hot Topic cubicle to get a look at its occupant.
The jacket is gone and the monitors are off. Mystery person has left for the day, I assume. I look at the large jars of nutritional supplements with macho names- Gorilla Rage, LumberJacked, Psycho Focus".
I notice the name-plate on the outside of the cubicle.
Oh, no.
Ian.

ETHE & GBTC (Grayscale) Frequently Asked Questions

It is no doubt Grayscale’s booming popularity as a mainstream investment has caused a lot of community hullabaloo lately. As such, I felt it was worth making a FAQ regarding the topic. I’m looking to update this as needed and of course am open to suggestions / adding any questions.
The goal is simply to have a thread we can link to anyone with questions on Grayscale and its products. Instead of explaining the same thing 3 times a day, shoot those posters over to this thread. My hope is that these questions are answered in a fairly simple and easy to understand manner. I think as the sub grows it will be a nice reference point for newcomers.
Disclaimer: I do NOT work for Grayscale and as such am basing all these answers on information that can be found on their website / reports. (Grayscale’s official FAQ can be found here). I also do NOT have a finance degree, I do NOT have a Series 6 / 7 / 140-whatever, and I do NOT work with investment products for my day job. I have an accounting background and work within the finance world so I have the general ‘business’ knowledge to put it all together, but this is all info determined in my best faith effort as a layman. The point being is this --- it is possible I may explain something wrong or missed the technical terms, and if that occurs I am more than happy to update anything that can be proven incorrect
Everything below will be in reference to ETHE but will apply to GBTC as well. If those two segregate in any way, I will note that accordingly.
What is Grayscale? 
Grayscale is the company that created the ETHE product. Their website is https://grayscale.co/
What is ETHE? 
ETHE is essentially a stock that intends to loosely track the price of ETH. It does so by having each ETHE be backed by a specific amount of ETH that is held on chain. Initially, the newly minted ETHE can only be purchased by institutions and accredited investors directly from Grayscale. Once a year has passed (6 months for GBTC) it can then be listed on the OTCQX Best Market exchange for secondary trading. Once listed on OTCQX, anyone investor can purchase at this point. Additional information on ETHE can be found here.
So ETHE is an ETF? 
No. For technical reasons beyond my personal understandings it is not labeled an ETF. I know it all flows back to the “Securities Act Rule 144”, but due to my limited knowledge on SEC regulations I don’t want to misspeak past that. If anyone is more knowledgeable on the subject I am happy to input their answer here.
How long has ETHE existed? 
ETHE was formed 12/14/2017. GBTC was formed 9/25/2013.
How is ETHE created? 
The trust will issue shares to “Authorized Participants” in groups of 100 shares (called baskets). Authorized Participants are the only persons that may place orders to create these baskets and they do it on behalf of the investor.

Note – The way their reports word this makes it sound like there is an army of authorizers doing the dirty work, but in reality there is only one Authorized Participant. At this moment the “Genesis” company is the sole Authorized Participant. Genesis is owned by the “Digital Currency Group, Inc.” which is the parent company of Grayscale as well. (And to really go down the rabbit hole it looks like DCG is the parent company of CoinDesk and is “backing 150+ companies across 30 countries, including Coinbase, Ripple, and Chainalysis.”)

How does Grayscale acquire the ETH to collateralize the ETHE product? 
An Investor may acquire ETHE by paying in cash or exchanging ETH already owned.
Source: Creation and Redemption of Shares section on page 40 of the “Grayscale Ethereum Trust Annual Report (2019)” – Located Here
Where does Grayscale store their ETH? Does it have a specific wallet address we can follow? 
ETH is stored with Coinbase Custody Trust Company, LLC. I am unaware of any specific address or set of addresses that can be used to verify the ETH is actually there.
As an aside - I would actually love to see if anyone knows more about this as it’s something that’s sort of peaked my interest after being asked about it… I find it doubtful we can find that however.
Source: Part C. Business Information, Item 8, subsection A. on page 16 of the “Grayscale Ethereum Trust Annual Report (2019)” – Located Here
Can ETHE be redeemed for ETH? 
No, currently there is no way to give your shares of ETHE back to Grayscale to receive ETH back. The only method of getting back into ETH would be to sell your ETHE to someone else and then use those proceeds to buy ETH yourself.
Source: Redemption Procedures on page 41 of the “Grayscale Ethereum Trust Annual Report (2019)” – Located Here
Why are they not redeeming shares? 
I think the report summarizes it best:
Redemptions of Shares are currently not permitted and the Trust is unable to redeem Shares. Subject to receipt of regulatory approval from the SEC and approval by the Sponsor in its sole discretion, the Trust may in the future operate a redemption program. Because the Trust does not believe that the SEC would, at this time, entertain an application for the waiver of rules needed in order to operate an ongoing redemption program, the Trust currently has no intention of seeking regulatory approval from the SEC to operate an ongoing redemption program.
Source: Redemption Procedures on page 41 of the “Grayscale Ethereum Trust Annual Report (2019)” – Located Here
What is the fee structure? 
ETHE has an annual fee of 2.5%. GBTC has an annual fee of 2.0%. Fees are paid by selling the underlying ETH / BTC collateralizing the asset.
Source: ETHE’s informational page on Grayscale’s website - Located Here
Source: Description of Trust on page 31 & 32 of the “Grayscale Ethereum Trust Annual Report (2019)” – Located Here
What is the ratio of ETH to ETHE? 
At the time of posting (6/19/2020) each ETHE share is backed by .09391605 ETH. Each share of GBTC is backed by .00096038 BTC.
ETHE & GBTC’s specific information page on Grayscale’s website updates the ratio daily – Located Here
For a full historical look at this ratio, it can be found on the Grayscale home page on the upper right side if you go to Tax Documents > 2019 Tax Documents > Grayscale Ethereum Trust 2019 Tax Letter.
Why is the ratio not 1:1? Why is it always decreasing? 
While I cannot say for certain why the initial distribution was not a 1:1 backing, it is more than likely to keep the price down and allow more investors a chance to purchase ETHE / GBTC.
As noted above, fees are paid by selling off the ETH collateralizing ETHE. So this number will always be trending downward as time goes on.
Source: Description of Trust on page 32 of the “Grayscale Ethereum Trust Annual Report (2019)” – Located Here
I keep hearing about how this is locked supply… explain? 
As noted above, there is currently no redemption program for converting your ETHE back into ETH. This means that once an ETHE is issued, it will remain in circulation until a redemption program is formed --- something that doesn’t seem to be too urgent for the SEC or Grayscale at the moment. Tiny amounts will naturally be removed due to fees, but the bulk of the asset is in there for good.
Knowing that ETHE cannot be taken back and destroyed at this time, the ETH collateralizing it will not be removed from the wallet for the foreseeable future. While it is not fully locked in the sense of say a totally lost key, it is not coming out any time soon.
Per their annual statement:
The Trust’s ETH will be transferred out of the ETH Account only in the following circumstances: (i) transferred to pay the Sponsor’s Fee or any Additional Trust Expenses, (ii) distributed in connection with the redemption of Baskets (subject to the Trust’s obtaining regulatory approval from the SEC to operate an ongoing redemption program and the consent of the Sponsor), (iii) sold on an as-needed basis to pay Additional Trust Expenses or (iv) sold on behalf of the Trust in the event the Trust terminates and liquidates its assets or as otherwise required by law or regulation.

Grayscale now owns a huge chunk of both ETH and BTC’s supply… should we be worried about manipulation, a sell off to crash the market crash, a staking cartel? 
First, it’s important to remember Grayscale is a lot more akin to an exchange then say an investment firm. Grayscale is working on behalf of its investors to create this product for investor control. Grayscale doesn’t ‘control’ the ETH it holds any more then Coinbase ‘controls’ the ETH in its hot wallet. (Note: There are likely some varying levels of control, but specific to this topic Grayscale cannot simply sell [legally, at least] the ETH by their own decision in the same manner Coinbase wouldn't be able to either.)
That said, there shouldn’t be any worry in the short to medium time-frame. As noted above, Grayscale can’t really remove ETH other than for fees or termination of the product. At 2.5% a year, fees are noise in terms of volume. Grayscale seems to be the fastest growing product in the crypto space at the moment and termination of the product seems unlikely.
IF redemptions were to happen tomorrow, it’s extremely unlikely we would see a mass exodus out of the product to redeem for ETH. And even if there was incentive to get back to ETH, the premium makes it so that it would be much more cost effective to just sell your ETHE on the secondary market and buy ETH yourself. Remember, any redemption is up to the investors and NOT something Grayscale has direct control over.
Yes, but what about [insert criminal act here]… 
Alright, yes. Technically nothing is stopping Grayscale from selling all the ETH / BTC and running off to the Bahamas (Hawaii?). BUT there is no real reason for them to do so. Barry is an extremely public figure and it won’t be easy for him to get away with that. Grayscale’s Bitcoin Trust creates SEC reports weekly / bi-weekly and I’m sure given the sentiment towards crypto is being watched carefully. Plus, Grayscale is making tons of consistent revenue and thus has little to no incentive to give that up for a quick buck.
That’s a lot of ‘happy little feels’ Bob, is there even an independent audit or is this Tether 2.0? 
Actually yes, an independent auditor report can be found in their annual reports. It is clearly aimed more towards the financial side and I doubt the auditors are crypto savants, but it is at least one extra set of eyes. Auditors are Friedman LLP – Auditor since 2015.
Source: Independent Auditor Report starting on page 116 (of the PDF itself) of the “Grayscale Ethereum Trust Annual Report (2019)” – Located Here
As mentioned by user TheCrpytosAndBloods (In Comments Below), a fun fact:
The company’s auditors Friedman LLP were also coincidentally TetheBitfinex’s auditors until They controversially parted ways in 2018 when the Tether controversy was at its height. I am not suggesting for one moment that there is anything shady about DCG - I just find it interesting it’s the same auditor.
“Grayscale sounds kind of lame” / “Not your keys not your crypto!” / “Why is anyone buying this, it sounds like a scam?” 
Welp, for starters this honestly is not really a product aimed at the people likely to be reading this post. To each their own, but do remember just because something provides no value to you doesn’t mean it can’t provide value to someone else. That said some of the advertised benefits are as follows:
So for example, I can set up an IRA at a brokerage account that has $0 trading fees. Then I can trade GBTC and ETHE all day without having to worry about tracking my taxes. All with the relative safety something like E-Trade provides over Binance.
As for how it benefits the everyday ETH holder? I think the supply lock is a positive. I also think this product exposes the Ethereum ecosystem to people who otherwise wouldn’t know about it.
Why is there a premium? Why is ETHE’s premium so insanely high compared to GBTC’s premium? 
There are a handful of theories of why a premium exists at all, some even mentioned in the annual report. The short list is as follows:
Why is ETHE’s so much higher the GBTC’s? Again, a few thoughts:

Are there any other differences between ETHE and GBTC? 
I touched on a few of the smaller differences, but one of the more interesting changes is GBTC is now a “SEC reporting company” as of January 2020. Which again goes beyond my scope of knowledge so I won’t comment on it too much… but the net result is GBTC is now putting out weekly / bi-weekly 8-K’s and annual 10-K’s. This means you can track GBTC that much easier at the moment as well as there is an extra layer of validity to the product IMO.
I’m looking for some statistics on ETHE… such as who is buying, how much is bought, etc? 
There is a great Q1 2020 report I recommend you give a read that has a lot of cool graphs and data on the product. It’s a little GBTC centric, but there is some ETHE data as well. It can be found here hidden within the 8-K filings.Q1 2020 is the 4/16/2020 8-K filing.
For those more into a GAAP style report see the 2019 annual 10-K of the same location.
Is Grayscale only just for BTC and ETH? 
No, there are other products as well. In terms of a secondary market product, ETCG is the Ethereum Classic version of ETHE. Fun Fact – ETCG was actually put out to the secondary market first. It also has a 3% fee tied to it where 1% of it goes to some type of ETC development fund.
In terms of institutional and accredited investors, there are a few ‘fan favorites’ such as Bitcoin Cash, Litcoin, Stellar, XRP, and Zcash. Something called Horizion (Backed by ZEN I guess? Idk to be honest what that is…). And a diversified Mutual Fund type fund that has a little bit of all of those. None of these products are available on the secondary market.
Are there alternatives to Grayscale? 
I know they exist, but I don’t follow them. I’ll leave this as a “to be edited” section and will add as others comment on what they know.
Per user Over-analyser (in comments below):
Coinshares (Formerly XBT provider) are the only similar product I know of. BTC, ETH, XRP and LTC as Exchange Traded Notes (ETN).
It looks like they are fully backed with the underlying crypto (no premium).
https://coinshares.com/etps/xbt-provideinvestor-resources/daily-hedging-position
Denominated in SEK and EUR. Certainly available in some UK pensions (SIPP).
As asked by pegcity - Okay so I was under the impression you can just give them your own ETH and get ETHE, but do you get 11 ETHE per ETH or do you get the market value of ETH in USD worth of ETHE? 
I have always understood that the ETHE issued directly through Grayscale is issued without the premium. As in, if I were to trade 1 ETH for ETHE I would get 11, not say only 2 or 3 because the secondary market premium is so high. And if I were paying cash only I would be paying the price to buy 1 ETH to get my 11 ETHE. Per page 39 of their annual statement, it reads as follows:
The Trust will issue Shares to Authorized Participants from time to time, but only in one or more Baskets (with a Basket being a block of 100 Shares). The Trust will not issue fractions of a Basket. The creation (and, should the Trust commence a redemption program, redemption) of Baskets will be made only in exchange for the delivery to the Trust, or the distribution by the Trust, of the number of whole and fractional ETH represented by each Basket being created (or, should the Trust commence a redemption program, redeemed), which is determined by dividing (x) the number of ETH owned by the Trust at 4:00 p.m., New York time, on the trade date of a creation or redemption order, after deducting the number of ETH representing the U.S. dollar value of accrued but unpaid fees and expenses of the Trust (converted using the ETH Index Price at such time, and carried to the eighth decimal place), by (y) the number of Shares outstanding at such time (with the quotient so obtained calculated to one one-hundred-millionth of one ETH (i.e., carried to the eighth decimal place)), and multiplying such quotient by 100 (the “Basket ETH Amount”). All questions as to the calculation of the Basket ETH Amount will be conclusively determined by the Sponsor and will be final and binding on all persons interested in the Trust. The Basket ETH Amount multiplied by the number of Baskets being created or redeemed is the “Total Basket ETH Amount.” The number of ETH represented by a Share will gradually decrease over time as the Trust’s ETH are used to pay the Trust’s expenses. Each Share represented approximately 0.0950 ETH and 0.0974 ETH as of December 31, 2019 and 2018, respectively.

Where's My Money? Deposits And Withdrawals At Blockfi, Celsius, Crypto.Com And Nexo Compared

Does your crypto show up in your account? And can you get it back? Looking through 100+ complaints about deposits and withdrawals, the insights are obvious but good to know...
- They require additional information like tags (XRP, XLM)
- Had major software changes (BCH, BNB, DAI / MCD, ADA)
So if you're going to move one of these coins, make sure to not forget the extra information or wait a few weeks after the change (to give these companies time to get caught up).
Raw data is below, organized by company and whether it seems the complaint was resolved. Some important notes to consider
  1. Posts about waiting a few hours for a transaction to complete were not counted. Many times (most of the time?) when it takes more than 20 minutes, nothing is broken. E.g. High gas fees on the ethereum network will mean slower processing times for stable coins and other ERC-20 tokens. Less popular tokens, like GUSD, might require people manually going into cold storage. Large (> $30,000 USD) transactions require additional verification. If it takes > 8 hours then yes something is not right. And you should email support and start posting. Otherwise sit tight.
  2. Comments from different people on the same post saying they have the same problem were not counted for "scores". Most of these comments don't add useful information and make it harder to collect the data.
  3. Posts about fiat belong to a different category because a very different set of skills and software features are needed to safely move around dollars, euros, etc. This post is about whether or not your coins are likely to get lost or be unreachable.
  4. I asked "Did this get fixed?" to a lot of people who posted about problems. Not only to see how things turned out. Also to generate a possible data point about the quality of the post. I.e. Trolls and other "special" people venting online can be identified by not bothering to follow up or respond to questions. I also hope this encourages people to not forget to follow up a few weeks later and share a final outcome - good or bad.

Bitcoin Hacks & basic ways to protect your Crypto

Interest in Bitcoin is increasing globally. More and more people are willing to participate in Bitcoin trading and mining. However, Bitcoin history shows that it is not always as safe as we would like it to be. Let’s take a look at some major Bitcoin hacks.

Allinvain

Allinvain is a nickname of a user on BitcoinTalk forums. Basically, he was the first one to experience a major Bitcoin loss. He lost 25,000 bitcoins, all together it was worth around $500,000. The user believed that someone hacked into his computer to steal BTC.

Mt Gox

Shortly after Allinvain’s case, the next hack attempt happened. Mt Gox was one of the biggest exchanges that provided a trade between Bitcoin and fiat money. Hackers compromised its website and started to sell Bitcoins. Their actions made the price go down dramatically. However, attackers did not pay attention to the $1000 limit Mt Gox had. Nonetheless, that hack attack had an important influence on BTC.

Other exchanges

Exchanges are being attacked by hackers quite often.
In 2012 Bitfloor suffered a terrible attack and lost 24,000 BTC (around $250,000). Unfortunately, this exchange was not able to survive the attack and was closed in 2013.
In 2015 Bitstamp exchange was hacked. It lost approximately 19,000 BTC (around $5 million).
In 2016 Bitfinex also lost 120,000 BTC (around $77 million) to hackers.

Twitter hack

The last attack happened in one of the biggest social nets. Twitter became a part of the latest attackers’ actions. The most significant and world-famous accounts promoted Bitcoin scam for several hours.

Anti-hack protection

The most important question is how to protect your Bitcoin savings from upcoming attacks. Here are some basic things that may help you to be safe:
Even though there is no way to be a hundred percent safe, there are a lot of steps we can take to avoid unfortunate losses. Cryptocurrency services are improving their protection systems all the time, and we all should do what we can to make this network more secure.

493 BTC were traded in Venezuela using LocalBitcoin (down from 544) last week, buying BTC with FIAT and selling BTC for FIAT (Bolivares, Venezuelan official currency). 544 BTC were 999,452,000,000 Bs. (Bolivares). One BTC is around 2,180,000,000 Bs. Monthly minimum wage is less than 5 USD

Just wanted to update the numbers, two weeks ago we were under 400 BTC first time in a long time. This week the volume recovered, so we are still at around 2,000 BTC monthly.
This is only measured using LocalBitcoin, there are other exchanges like AIRTM, Uphold, Binance and so on, but no open data as far as I know. Most of the Localbitcoin trades are in Bolivares.
I recommend reading this website, it is one of the best english websites for Venezuela news (they sometimes touch the crypto and economic situation).
https://www.caracaschronicles.com/
Last week by a serious NGO released a survey (it is called Encovi) they concluded the average income of the Venezuela is 0.72 USD daily. I think that is true, around 20-30 USD per month.
https://www.caracaschronicles.com/2020/07/08/yes-venezuela-is-now-the-poorest-country-in-the-americas/
Any question let me know, AMA. But check my links and sources first.
