Technical: The Path to Taproot Activation

Taproot! Everybody wants to have it, somebody wants to make it, nobody knows how to get it!
(If you are asking why everybody wants it, see: Technical: Taproot: Why Activate?)
(Pedants: I mostly elide over lockin times)
Briefly, Taproot is that neat new thing that gets us:
So yes, let's activate taproot!

The SegWit Wars

The biggest problem with activating Taproot is PTSD from the previous softfork, SegWit. Pieter Wuille, one of the authors of the current Taproot proposal, has consistently held the position that he will not discuss activation, and will accept whatever activation process is imposed on Taproot. Other developers have expressed similar opinions.
So what happened with SegWit activation that was so traumatic? SegWit used the BIP9 activation method. Let's dive into BIP9!

BIP9 Miner-Activated Soft Fork

Basically, BIP9 has a bunch of parameters:
Now there are other parameters (name, starttime) but they are not anywhere near as important as the above two.
A number that is not a parameter, is 95%. Basically, activation of a BIP9 softfork is considered as actually succeeding if at least 95% of blocks in the last 2 weeks had the specified bit in the nVersion set. If less than 95% had this bit set before the timeout, then the upgrade fails and never goes into the network. This is not a parameter: it is a constant defined by BIP9, and developers using BIP9 activation cannot change this.
So, first some simple questions and their answers:

The Great Battles of the SegWit Wars

SegWit not only fixed transaction malleability, it also created a practical softforkable blocksize increase that also rebalanced weights so that the cost of spending a UTXO is about the same as the cost of creating UTXOs (and spending UTXOs is "better" since it limits the size of the UTXO set that every fullnode has to maintain).
So SegWit was written, the activation was decided to be BIP9, and then.... miner signalling stalled at below 75%.
Thus were the Great SegWit Wars started.

BIP9 Feature Hostage

If you are a miner with at least 5% global hashpower, you can hold a BIP9-activated softfork hostage.
You might even secretly want the softfork to actually push through. But you might want to extract concession from the users and the developers. Like removing the halvening. Or raising or even removing the block size caps (which helps larger miners more than smaller miners, making it easier to become a bigger fish that eats all the smaller fishes). Or whatever.
With BIP9, you can hold the softfork hostage. You just hold out and refuse to signal. You tell everyone you will signal, if and only if certain concessions are given to you.
This ability by miners to hold a feature hostage was enabled because of the miner-exit allowed by the timeout on BIP9. Prior to that, miners were considered little more than expendable security guards, paid for the risk they take to secure the network, but not special in the grand scheme of Bitcoin.

Covert ASICBoost

ASICBoost was a novel way of optimizing SHA256 mining, by taking advantage of the structure of the 80-byte header that is hashed in order to perform proof-of-work. The details of ASICBoost are out-of-scope here but you can read about it elsewhere
Here is a short summary of the two types of ASICBoost, relevant to the activation discussion.
Now, "overt" means "obvious", while "covert" means hidden. Overt ASICBoost is obvious because nVersion bits that are not currently in use for BIP9 activations are usually 0 by default, so setting those bits to 1 makes it obvious that you are doing something weird (namely, Overt ASICBoost). Covert ASICBoost is non-obvious because the order of transactions in a block are up to the miner anyway, so the miner rearranging the transactions in order to get lower power consumption is not going to be detected.
Unfortunately, while Overt ASICBoost was compatible with SegWit, Covert ASICBoost was not. This is because, pre-SegWit, only the block header Merkle tree committed to the transaction ordering. However, with SegWit, another Merkle tree exists, which commits to transaction ordering as well. Covert ASICBoost would require more computation to manipulate two Merkle trees, obviating the power benefits of Covert ASICBoost anyway.
Now, miners want to use ASICBoost (indeed, about 60->70% of current miners probably use the Overt ASICBoost nowadays; if you have a Bitcoin fullnode running you will see the logs with lots of "60 of last 100 blocks had unexpected versions" which is exactly what you would see with the nVersion manipulation that Overt ASICBoost does). But remember: ASICBoost was, at around the time, a novel improvement. Not all miners had ASICBoost hardware. Those who did, did not want it known that they had ASICBoost hardware, and wanted to do Covert ASICBoost!
But Covert ASICBoost is incompatible with SegWit, because SegWit actually has two Merkle trees of transaction data, and Covert ASICBoost works by fudging around with transaction ordering in a block, and recomputing two Merkle Trees is more expensive than recomputing just one (and loses the ASICBoost advantage).
Of course, those miners that wanted Covert ASICBoost did not want to openly admit that they had ASICBoost hardware, they wanted to keep their advantage secret because miners are strongly competitive in a very tight market. And doing ASICBoost Covertly was just the ticket, but they could not work post-SegWit.
Fortunately, due to the BIP9 activation process, they could hold SegWit hostage while covertly taking advantage of Covert ASICBoost!

UASF: BIP148 and BIP8

When the incompatibility between Covert ASICBoost and SegWit was realized, still, activation of SegWit stalled, and miners were still not openly claiming that ASICBoost was related to non-activation of SegWit.
Eventually, a new proposal was created: BIP148. With this rule, 3 months before the end of the SegWit timeout, nodes would reject blocks that did not signal SegWit. Thus, 3 months before SegWit timeout, BIP148 would force activation of SegWit.
This proposal was not accepted by Bitcoin Core, due to the shortening of the timeout (it effectively times out 3 months before the initial SegWit timeout). Instead, a fork of Bitcoin Core was created which added the patch to comply with BIP148. This was claimed as a User Activated Soft Fork, UASF, since users could freely download the alternate fork rather than sticking with the developers of Bitcoin Core.
Now, BIP148 effectively is just a BIP9 activation, except at its (earlier) timeout, the new rules would be activated anyway (instead of the BIP9-mandated behavior that the upgrade is cancelled at the end of the timeout).
BIP148 was actually inspired by the BIP8 proposal (the link here is a historical version; BIP8 has been updated recently, precisely in preparation for Taproot activation). BIP8 is basically BIP9, but at the end of timeout, the softfork is activated anyway rather than cancelled.
This removed the ability of miners to hold the softfork hostage. At best, they can delay the activation, but not stop it entirely by holding out as in BIP9.
Of course, this implies risk that not all miners have upgraded before activation, leading to possible losses for SPV users, as well as again re-pressuring miners to signal activation, possibly without the miners actually upgrading their software to properly impose the new softfork rules.

BIP91, SegWit2X, and The Aftermath

BIP148 inspired countermeasures, possibly from the Covert ASiCBoost miners, possibly from concerned users who wanted to offer concessions to miners. To this day, the common name for BIP148 - UASF - remains an emotionally-charged rallying cry for parts of the Bitcoin community.
One of these was SegWit2X. This was brokered in a deal between some Bitcoin personalities at a conference in New York, and thus part of the so-called "New York Agreement" or NYA, another emotionally-charged acronym.
The text of the NYA was basically:
  1. Set up a new activation threshold at 80% signalled at bit 4 (vs bit 1 for SegWit).
    • When this 80% signalling was reached, miners would require that bit 1 for SegWit be signalled to achive the 95% activation needed for SegWit.
  2. If the bit 4 signalling reached 80%, increase the block weight limit from the SegWit 4000000 to the SegWit2X 8000000, 6 months after bit 1 activation.
The first item above was coded in BIP91.
Unfortunately, if you read the BIP91, independently of NYA, you might come to the conclusion that BIP91 was only about lowering the threshold to 80%. In particular, BIP91 never mentions anything about the second point above, it never mentions that bit 4 80% threshold would also signal for a later hardfork increase in weight limit.
Because of this, even though there are claims that NYA (SegWit2X) reached 80% dominance, a close reading of BIP91 shows that the 80% dominance was only for SegWit activation, without necessarily a later 2x capacity hardfork (SegWit2X).
This ambiguity of bit 4 (NYA says it includes a 2x capacity hardfork, BIP91 says it does not) has continued to be a thorn in blocksize debates later. Economically speaking, Bitcoin futures between SegWit and SegWit2X showed strong economic dominance in favor of SegWit (SegWit2X futures were traded at a fraction in value of SegWit futures: I personally made a tidy but small amount of money betting against SegWit2X in the futures market), so suggesting that NYA achieved 80% dominance even in mining is laughable, but the NYA text that ties bit 4 to SegWit2X still exists.
Historically, BIP91 triggered which caused SegWit to activate before the BIP148 shorter timeout. BIP148 proponents continue to hold this day that it was the BIP148 shorter timeout and no-compromises-activate-on-August-1 that made miners flock to BIP91 as a face-saving tactic that actually removed the second clause of NYA. NYA supporters keep pointing to the bit 4 text in the NYA and the historical activation of BIP91 as a failed promise by Bitcoin developers.

Taproot Activation Proposals

There are two primary proposals I can see for Taproot activation:
  1. BIP8.
  2. Modern Softfork Activation.
We have discussed BIP8: roughly, it has bit and timeout, if 95% of miners signal bit it activates, at the end of timeout it activates. (EDIT: BIP8 has had recent updates: at the end of timeout it can now activate or fail. For the most part, in the below text "BIP8", means BIP8-and-activate-at-timeout, and "BIP9" means BIP8-and-fail-at-timeout)
So let's take a look at Modern Softfork Activation!

Modern Softfork Activation

This is a more complex activation method, composed of BIP9 and BIP8 as supcomponents.
  1. First have a 12-month BIP9 (fail at timeout).
  2. If the above fails to activate, have a 6-month discussion period during which users and developers and miners discuss whether to continue to step 3.
  3. Have a 24-month BIP8 (activate at timeout).
The total above is 42 months, if you are counting: 3.5 years worst-case activation.
The logic here is that if there are no problems, BIP9 will work just fine anyway. And if there are problems, the 6-month period should weed it out. Finally, miners cannot hold the feature hostage since the 24-month BIP8 period will exist anyway.

PSA: Being Resilient to Upgrades

Software is very birttle.
Anyone who has been using software for a long time has experienced something like this:
  1. You hear a new version of your favorite software has a nice new feature.
  2. Excited, you install the new version.
  3. You find that the new version has subtle incompatibilities with your current workflow.
  4. You are sad and downgrade to the older version.
  5. You find out that the new version has changed your files in incompatible ways that the old version cannot work with anymore.
  6. You tearfully reinstall the newer version and figure out how to get your lost productivity now that you have to adapt to a new workflow
If you are a technically-competent user, you might codify your workflow into a bunch of programs. And then you upgrade one of the external pieces of software you are using, and find that it has a subtle incompatibility with your current workflow which is based on a bunch of simple programs you wrote yourself. And if those simple programs are used as the basis of some important production system, you hve just screwed up because you upgraded software on an important production system.
And well, one of the issues with new softfork activation is that if not enough people (users and miners) upgrade to the newest Bitcoin software, the security of the new softfork rules are at risk.
Upgrading software of any kind is always a risk, and the more software you build on top of the software-being-upgraded, the greater you risk your tower of software collapsing while you change its foundations.
So if you have some complex Bitcoin-manipulating system with Bitcoin somewhere at the foundations, consider running two Bitcoin nodes:
  1. One is a "stable-version" Bitcoin node. Once it has synced, set it up to connect=x.x.x.x to the second node below (so that your ISP bandwidth is only spent on the second node). Use this node to run all your software: it's a stable version that you don't change for long periods of time. Enable txiindex, disable pruning, whatever your software needs.
  2. The other is an "always-up-to-date" Bitcoin Node. Keep its stoarge down with pruning (initially sync it off the "stable-version" node). You can't use blocksonly if your "stable-version" node needs to send transactions, but otherwise this "always-up-to-date" Bitcoin node can be kept as a low-resource node, so you can run both nodes in the same machine.
When a new Bitcoin version comes up, you just upgrade the "always-up-to-date" Bitcoin node. This protects you if a future softfork activates, you will only receive valid Bitcoin blocks and transactions. Since this node has nothing running on top of it, it is just a special peer of the "stable-version" node, any software incompatibilities with your system software do not exist.
Your "stable-version" Bitcoin node remains the same version until you are ready to actually upgrade this node and are prepared to rewrite most of the software you have running on top of it due to version compatibility problems.
When upgrading the "always-up-to-date", you can bring it down safely and then start it later. Your "stable-version" wil keep running, disconnected from the network, but otherwise still available for whatever queries. You do need some system to stop the "always-up-to-date" node if for any reason the "stable-version" goes down (otherwisee if the "always-up-to-date" advances its pruning window past what your "stable-version" has, the "stable-version" cannot sync afterwards), but if you are technically competent enough that you need to do this, you are technically competent enough to write such a trivial monitor program (EDIT: gmax notes you can adjust the pruning window by RPC commands to help with this as well).
This recommendation is from gmaxwell on IRC, by the way.

Forex Trading in Kenya.

Someone posted on here a few days ago asking about forex and forex trading in Kenya, I have gone through the responses and clearly, most people don’t have an idea. It is 3am in the morning and am in a good mood so let me make this post. This will be a comprehensive and lengthy post so grab a pen and paper and sit down. We’ll be here a while.
FIRST OF ALL, who am I..?
I am a forex trader, in Nairobi, Kenya..i have been actively involved in forex since I found out about it in Feb 2016 when I somehow ended up in a wealth creation seminar (lol) in pride inn Westlands, the one close to Mpaka Rd. Luckily for me, it was not one of those AIM global meetings or I’d be on Facebook selling God knows what those guys sell. I did not take it seriously till August of the same year and I have been active ever since.
I don’t teach, mentor or sell a course or signals, I trade my own money. I am also posting from a throwaway account because I don’t want KRA on my ass.
What the fuck is forex and forex trading.
In simple plain English, forex is like the stock market but for currencies. Stock Market = Shares, forex = currencies. If you want more in-depth explanation, google is your friend.
These currencies are pegged on specific countries, united states- dollar, UK- pound, euro zone- euro, Switzerland- Swiss franc, Kenya- Kenya shilling.. you get the point. Now, there are specific events and happenings between these economies that affect the movement and values of the currencies, driving their value (purchasing power up and down). Forex trading exploits these movements to make money. When the value is going up, we buy and vice versa (down –sell)
Is forex trading illegal in Kenya? Is it a scam?
Illegal, no. scam, no. All the banks in the world do it (KCB made about 4 billion from trading forex in 2019)
Have there been scams involving forex in Kenya?
Yes. Here is one that happened recently. This one is the most infamous one yet. Best believe that this is not the end of these type of scams because the stupidity, greed and gullibility of human beings is unfathomable.
However, by the end of this post, I hope you won’t fall for such silliness.
What next how do I make it work..?
Am glad you asked. Generally, there are two ways to go about it. One, you teach yourself. This is the equivalent of stealing our dad’s car and hoping that the pedal you hit is the brake and not the accelerator. It is the route I took, it is the most rewarding and a huge ego boost when you finally make it on your own. Typically, this involves scouring the internet for hours upon hours going down rabbit holes, thinking you have made it telling all your friends how you will be a millionaire then losing all your money. Some people do not have the stomach for that.
The second route is more practical, structured and smarter.
First Learn the basics. There is a free online forex course at www.babypips.com/learn/forex this is merely an introductory course. Basically it is learning the parts of a car before they let you inside the car.
Second, start building your strategy. By the time you are done with the babypips, you will have a feel of what the forex market is, what interests you, etc. Tip..Babypips has a lot of garbage. It is good for introductory purposes but not good for much else, pick whatever stick to you or jumps at you the first time. Nonsense like indicators should be ignored.
The next step is now the most important. Developing the skill and building your strategy. As a beginner, you want to exhaust your naivety before jumping into the more advanced stuff. Eg can you identify a trend, what is a pair, what is position sizing, what is metatrader 4 and how to operate it, what news is good for a currency, when can I trade, what are the different trading sessions, what is technical analysis, what is market sentiment, what are bullish conditions what is emotion management, how does my psychology affect my trading (more on this later) an I a swing, scalper or day trader etc
Mentors and forex courses.. you have probably seen people advertising how they can teach and mentor you on how to trade forex and charging so much money for it. Somehow it seems that these people are focused on the teaching than the trading. Weird, right..? Truth is trading is hard, teaching not quite. A common saying in the industry is “Those who can’t trade, teach” you want to avoid all these gurus on Facebook and Instagram, some are legit but most are not. Sifting the wheat from the chaff is hard but I did that for you. The info is available online on YouTube, telegram channels etc. am not saying not to spend money on a course, if you find a mentor whose style resonates with you and the course is reasonably priced, please, go ahead and buy..it will cut your learning curve in half. People are different. What worked for me might not work for you.
Here are some nice YouTube channels to watch. These guys are legit..
  1. Sam sieden
  2. Cuebanks
  3. TheCoinFx
  4. The trading channel
  5. Astro
  6. Forex family
  7. Wicksdontlie
Advanced stuff
  1. ICT
After a short period of time, you will be able to sniff out bs teachers with relative ease. You will also discover some of your own and expand the list. Two tips, start with the oldest videos first and whichever of these resonates with you, stick with till the wheels fall off.
How long will it take until things start making sense
Give yourself time to grow and learn. This is all new to you and you are allowed to make mistakes, to fail and discover yourself. Realistically, depending on the effort you put in, you will not start seeing results until after 6 months. Could take longeshorter so there is no guarantee.
Social media, Mentality, Psychology and Books
Online, forex trading might not have the best reputation online because it takes hard work and scammers and gurus give it a bad name. However, try to not get sucked into the Instagram trader lifestyle as it is nowhere close to what the reality is. You will not make millions tomorrow or the day after, you might never even make it in this market. But that is the reality of life. Nothing is promised, nothing is guaranteed.
Your mentality, beliefs and ego will be challenged in this market. You will learn things that will make you blood boil, you will ask yourself daily, how is this possible, why don’t they teach this in school..bla bla bla..it will be hard but growth is painful, if it wasn’t we’d all be billionaires. Take a break, take a walk, drink a glass of whatever you like or roll one..detox. Chill with your girl (or man) Gradually you will develop mental toughness that will set you up for life. Personally, I sorta ditched religion and picked up stoicism. Whatever works for you.
Psychology, this is unfortunately one of the most neglected aspects of your personal development in this journey. Do you believe in yourself? Can you stand by your convictions when everyone is against you? Can you get up every day uncertain of the future? There will be moments where you will question yourself, am I even doing the right thing? the right way? It is normal and essential for your growth. People who played competitive sports have a natural advantage here. Remember the game is first won in your head then on the pitch.
Books: ironically, books that helped me the most were the mindset books, Think and grow rich, trading for a living, 4 hour work week, the monk who sold his Ferrari..just google mindset and psychology books, most trading books are garbage. Watch and listen to people who have made it in the investing business. Ray Dalio, warren, Bill Ackman and Carl Icahn.
This is turning out to be lengthier than I anticipated so I’ll try to be brief for the remaining parts.
Brokers
You will need to open up an account with a broker. Get a broker who is regulated. Australian ones (IC Market and Pepperstone) are both legit, reliable and regulated. Do your research. I’d avoid local ones because I’ve heard stories of wide spreads and liquidity problems. International brokers have never failed me. There are plenty brokers, there is no one size fits all recommendation. If it ain’t broke..don’t fix it.
Money transfer.
All brokers accept wire transfers, you might need to call your bank to authorize that, avoid Equity bank. Stanchart and Stanbic are alright. Large withdrawals $10k+ you will have to call them prior. Get Skrill and Neteller if you don’t like banks like me, set up a Bitcoin wallet for faster withdrawals, (Payoneer and Paypal are accepted by some brokers, just check with them.)
How much money can I make..?
I hate this question because people have perceived ceilings of income in their minds, eg 1 million ksh is too much to make per month or 10,000ksh is too little. Instead, work backwards. What % return did I make this month/ on this trade. Safaricom made 19.5% last year, if you make 20% you have outperformed them. If you reach of consistency where you can make x% per month on whatever money you have, then there are no limits to how much you can make.
How much money do I need to start with..?
Zero. You have all the resources above, go forth. There are brokers who provide free bonuses and withdraw-able profits. However, to make a fulltime income you will need some serious cash. Generally, 50,000 kes. You can start lower or higher but if you need say 20k to live comfortably and that is a 10% return per month, then you can do the math on how big your account should be. Of course things like compound interest come into play but that is dependent on your skill level. I have seen people do spectacular things with very little funds.
Taxes..?
Talk to a lawyer or an accountant. I am neither.
Family? Friends?
Unfortunately, people will not understand why you spend hundreds of hours watching strangers on the internet so it is best to keep it from them. Eventually you will make it work and they will come to your corner talking about how they always knew you’d make it.
The journey will be lonely, make some trading buddies along the way. You’d be surprised at how easy it is when people are united by their circumstances (and stupidity) I have guys who are my bros from South Africa and Lebanon who I have never met but we came up together and are now homies. Join forums, ask questions and grow. That is the only way to learn. Ideally, a group of 5-10 friends committed to learning and growth is the best model. Pushing each other to grow and discovering together.
Forex is real and you can do amazing things with it. It is not a get rich quick scheme. If you want a quick guaranteed income, get a job.
And now it is 5am, fuck.
This is oversimplified and leaves out many many aspects.
Happy to answer any questions.

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!

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.

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.

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.

Will send 0.004 btc to anyone who can answer a simple question without being a condescending jerk

I've asked this before but the answer (as is so often the case with Reddit) was to RTFM. I don't have any interest in becoming a Bitcoin expert, I just have a specific question for my simple use case of Bitcoin:
How can I set up multiple receiving addresses that can't be tied to each other and get cash money out the other end?
I'm in .au so have coinspot and independent reserve accounts, I also have bitpay. I'm unsure if I'm better off setting up single use (auditable) wallets in bitpay or if it's ok to use a multi wallet which has a new address each time but I think still has some overarching user ID that someone could tie them together. Finally, it's all pointless if IR's wallet accounts can be tied together somehow. I know this sub seems to dislike bitpay but it seems pretty convenient and needs suiting and every time you check a list of "better" apps they all have various issues I'm not interested in stuffing around with, but I'm not married to bitpay if there's honestly a better solution. I don't need an iron clad system but rather something that isn't trivial to see that "hey, all these payments are ending up at the same place" - so I guess if the way IR creates new receiving addresses are all under some unified ID then that's an issue?
So I guess the short version of the question is how would someone not interested in running overly complex systems setup multiple receiving wallets and get them to cash in .au without the sender being able to tie them all together, at least not easily.
Thanks and I'll honestly send whoever can give a good answer some coin.
Ps. Crap I just realised it sounds like I'm trying to avoid taxes or something. That's not the case, I don't want the sender of the coins or some random person to be able to link the transactions. I know once it hits the bank accounts the government will know about it, I'm not concerned with that.
PPS. I'm going to bed now so don't think I've just bailed and am not going to pay anyone giving a good answer, I'll be up can pay someone within 10 hours

1. What is Energi

Energi is a self-funding (no ICO and no premine) cryptocurrency that has a purpose to become the world’s leading cryptocurrency with the unification of Smart Contracts, Governance and Self-funding Treasury to ensure longevity and enable rapid growth. You can read more about why we decided to self-fund and chose not to conduct an ICO here.
Energi provides a small allocation to Proof-of-Stake (PoS) rewards, takes a bulk of the coin issuance and gives it to its treasury and active Masternodes. Energi also allocates 10% on-going reward to the leadership of the Energi Backbone, which is significantly less compared to today’s ICOs’ rewarding their founders between 20–50% of the tokens distributed. Another trait that sets Energi apart from ICOs is they give an on-going 10% allocation through each block reward, rather than rewarding the founders up-front.

2. What are the Fundamentals of Energi?

  • Scalability
1 minute block times and a 2 megabyte block size limit provide Energi with a vast transaction capacity for regular on-chain transactions. This allows for plenty of space on the blockchain for extremely fast transactions with very low fees.
Energi features a powerful on-chain scaling solution with a system of incentivized full nodes called Energi Masternodes. A Masternode is a full node backed by 1,000 NRG collateral that provides level 2 scalability to the Energi Cryptocurrency. 40% of the emissions of Energi is allocated to Masternodes, providing an extremely strong incentive to grow the number of full nodes and scalability of the network.

  • Funding
A key feature of Energi is its powerful treasury system. Energi makes up to 40% of the emissions available to the treasury, to be utilized in a manner that provides maximum benefit.
Treasury allocation is decentralized, allowing for submitted proposals from anyone, to be voted on by Masternodes and paid out from the emissions.
Energi has a 14 day treasury cycle, allowing quick payments for proposal authors and contributors, as well as strategic responsiveness to effective proposals. Energi is guided by the principle that every dollar spent from its funding model should yield more than one dollar of value in return. Thanks to a 14 day treasury cycle, the Energi team is able to measure results and respond quickly to changes in strategy.

  • Governance
The Energi Treasury is a decentralized governance model designed with Masternodes as caretakers, with voting rights on how to best utilize treasury funding.
This governance model reduces risk by allowing participation from everyone who holds 1,000 NRG as a Masternode. In this way, the Energi community can work together on how to best build the strategic direction of Energi.

  • Inflation
Energi Cryptocurrency has a simple rate of inflation at 1 million coins per month with no maximum cap. This ensures consistency in funding allocation, Masternode rewards, and PoS rewards, making the economics of the cryptocurrency more understandable for everyone who chooses to participate in Energi.
No coin supply limit ensures that Energi is prepared for the long term, avoiding “bubble” economics caused by dramatic early inflation that in most coins only serves to benefit founders ahead of increased adoption.

  • Distribution
Energi conducted a fair launch on April 14, 2018 with no ICO and no premine. Prior to launch, the Energi team gave a specific time and date for the launch of its main net, which its vibrant community eagerly awaited, so that mining could begin fairly, again avoiding centralization among the coin founders (It's important to note that Energi has transitioned from Proof-of-Work consensus to a Proof-of-Stake consensus).
Energi Masternode payments were designed to begin at block 216000, which occurred on September 18, 2018, almost 160 days after launch. This ensured time to list Energi on exchanges, and to grow the community, encouraging fair and equitable distribution before the extremely powerful Masternode rewards began. It is all too common for Masternode coins to feature a premine, which has the effect of centralizing distribution among the founders and early adopters.
From 2018 to 2020, Energi distributed nearly 4 million coins to users who contributed to spreading awareness of the project with social media activities about Energi, such as tweets, follows, and subscriptions on all major social media platforms.

  • Decentralization
Decentralized governance with Masternodes helps to ensure everyone is able to participate in Energi and help guide the project to achieve the best results. The change to the requirement to run a Masternode, from 10 000 NRG to 1 000 NRG, has allowed more people to be involved and boosted decentralization for the whole project.

  • Long Term Vision
All of the above features seamlessly work together in concert, to ensure that Energi is prepared for the long term. Rather than try to closely find a niche in the market, Energi is prepared to adapt and overcome all challenges for many years to come. Energi’s use case is that of a traditional cryptocurrency, such as Bitcoin. However, Energi’s strategy is to excel by avoiding the pitfalls of previous projects, while further utilizing and improving upon the most powerful ideas in the cryptocurrency space.

3. Coin Specs

Ticker: NRG
Block time: 1 minute.
Hashing Algorithm: Dagger-Hashimoto (similar to Ethereum).
Masternode requirements: 1,000 Energi.
Treasury cycle: Every 14 days.
Approximately 1 million Energi will be released per month. The allocations can be observed easily as “10/10/40/40.”
10% will go to the Energi Backbone.
10% to the PoS participants
40% to Masternodes.
40% to the Treasury.
Thus, for every block, allocations are: 2.28 Energi to the Backbone, 2.28 Energi to the PoS participants, 9.14 Energi to the Treasury, and 9.14 Energi to Masternodes.
Since Treasury allocations are paid in two-week cycles, they are made in lump sums of approximately 184,000 Energi every 14 days.
In order to allow for widespread distribution of Energi before Masternode payments began, Masternode rewards were delayed until day 150. This was to allow the airdrop campaign to be completed and ensure a large amount of NRG is spread out through the community. Until that point, Masternode rewards were redirected to the Treasury. Thus for the first 5 months, the Treasury gained approximately 368,000 Energi every two weeks (about 800k Energi per month). The airdrop campaign was designed to release ~4 million Energi to the community.

Monero - The Elephant in the Room

The state of financial privacy in 2020
Note: You can read this in a friendlier format with images over on Medium - https://medium.com/@johnfoss/the-elephant-in-the-room-34e061f5912a
The erosion of personal privacy is gaining momentum since the coronavirus pandemic took hold. Worldwide, there have been numerous calls by governments and social commentators to increase the surveillance of citizens in h
