The Unofficial Cardano FAQ - V3

(if you would like to add information or see mistakes, just comment below and I will credit you)
What is Cardano? Cardano is an open source and permissionless "Third Generation" blockchain project being developed by IOHK. Development and research started in 2015, with the 1.0 mainnet launching in 2017. Cardano blockchain is currently being developed into two layers. The first one is the ledger of account values, and the second one is the reason why values are transferred from one account to the other.
  1. Cardano Settlement Layer (CSL) - The CSL acts as the ledger of account or balance ledger. This is an idea created as an improvement of bitcoin blockchain. It uses a proof-of-stake consensus algorithm known as Ouroboros to generate new blocks and confirm transactions.
  2. Cardano Computation Layer (CCL) - The CCL contains the data how values are transferred. Since the computation layer is not connected to balance ledger, users of the CCL can create customized rules (smart contracts) when evaluating transactions. (https://support.bitkub.com/hc/en-us/articles/360006678892-What-are-the-two-layers-of-Cardano-)
IOHK has the contract with an undisclosed party to develop the project until the end of 2020, at which point the community may elect another development team - on the assumption that the voting infrastructure has been completed. However CEO Charles Hoskinson has stated that they will develop the project until it is completed, and they are simply financed until the end of 2020.
Cardano was the first project built on a peer-reviewed scientific development method, resulting in dozens of research papers produced by IOHK. Among these papers is Ouroboros Genesis, proving that a Proof of Stake protocol can be just as secure as Proof of Work - which was originally developed for Bitcoin, and refined for Ethereum. This PoS protocol considerably lowers the resources cost to maintain network while still maintaining security and network speed.
Cardano as a financial infrastructure is not yet completed, With significant development to be rolled out.
What were the other two generations of blockchain? Gen 1 was Bitcoin. It exists by itself and talks to nobody but Bitcoin. It is capable of peer to peer transactions without a third party in such a way that you cannot cheat the system. This was a major step forward for the E-cash concept that people have been working on for the 20 years prior.
Gen 2 was Ethereum and other smart-contract platforms that allow other coins and platforms to be built on top of their infrastructure. These coins can interact with others on the platform, but cannot interact with other platforms. Meaning it is still not truly interoperable. Most Gen 2 blockchains are also using Proof of Work likes Bitcoin, which effects scaling. Also missing is a built-in method to pay for upgrades and voting mechanics for decision making.
Gen 3 blockchains are a complete package designed to replace the current financial infrastructure of the world. Cardano is using Proof of Stake to ensure security and decentralisation(Shelley). Scaling through parallel computation (Hydra in Basho), Sidechains to allow the platform to interact with other platforms (Basho), and also include mechanisms for voting for project funding, changes to the protocol and improvement proposals (Voltaire). Finally smart contracts platform for new and established projects that are developer friendly (Goguen).
Who is the team behind Cardano? There are three organisations that are contributing to the development of Cardano. The first is the Cardano Foundation, an objective, non-profit organisation based in Switzerland. Its core responsibilities are to nurture, grow and educate Cardano users and commercial communities, to engage with authorities on regulatory and commercial matters and to act as a blockchain and cryptocurrency standards body. The second entity is IOHK, a leading cryptocurrency research and development company, which holds the contract to develop the platform until 2020. The final business partner is Emurgo, which invests in start-ups and assists commercial ventures to build on the Cardano blockchain.

What is the difference between Proof of Work and Proof of stake? Both these protocols are known as “consensus protocols” that confirm whether a transaction is valid or invalid without a middleman like Visa or your bank. Every node (active and updated copy of the blockchain) can agree that the transaction did take place legitimately. If more than half validators agree, then the ledger is updated and the transaction is now secured. Proof-of-Work (PoW) happens when a miner is elected to solve an exceptionally difficult math problem and gets credit for adding a verified block to the blockchain. Finding a solution is an arduous guessing game that takes a considerable amount of computing power to compete for the correct answer. It is like “pick a number between 1 and one trillion” and when you get it right, you get $30,000 in Bitcoin, so the more computers you have working on it, the faster you can solve it. Also the more people who are trying to solve the same block, the harder the algorithm, so it may become 1 in 20 trillion. The downside is the massive amounts of power required to run the computers that run the network, and the slow pace that blocks are solved. To “Hack” a PoW system, you need 51% of the computing power, which would allow you to deny transactions, or spend the same coin twice. At the moment there are 8 main mining operations for bitcoin, and 4 of them make up more that 51% of the mining power.
PoS instead selects a coin at random that already exists, and the person who owns that coin is elected to put the work in to validate the block. This means there is no contest and no guessing game. Some computer power is required, but only a fraction of a PoW system. The complex nature of selecting a coin that exists on the correct and longest chain and is owned by someone who can complete the block, AND in such a way that it is secure AND that computer currently running AND that person also having an incentive to complete the work, has made the development of PoS very slow. However only a few years ago it wasn’t even possible. In this method, the more of the coin (ADA) you stake, the more likely you are to be selected to close a block. Cardano also allows you to delegate your stake to someone else to validate the block so they do the work, and you share in the reward for doing so.
To “hack” a PoS blockchain you need to own 51% of the tokens, which is significantly harder than owning 51% of the computing power.
What is ADA and how is it different to Cardano? Cardano is the name of the network infrastructure, and can be thought of like a rail network. ADA is the native token that has been developed alongside Cardano to facilitate the network operation. This helps confusion and maintains distinction, compared to Ethereum being the native token of Ethereum. Similar to bitcoin or any other token, ADA can be sent peer to peer as payment, but is also the reward for running the network, and what is taken as transaction fees.
In this metaphor “Cardano” is the train tracks, that everything runs on. A stake pool would be the locomotive, facilitating transactions on the network while ADA is the coal that powers the locomotive. The train carriages are Decentralised applications (Dapps) that are also running on cardano tracks, but are not actively powering the network.
What is staking Cardano is a Proof of Stake protocol, and uses already existing coins like a marker to ensure security. The protocol chooses a coin at random and the owner of that coin is elected to validate a block of transactions. Staking is the process of adding your ADA coins to a Pool that has the resources to run the network. If the pool you have chosen to "delegate" your stake to is chosen to close/validate a block, then you get a portion of the rewards. The ADA never leaves your wallet, and you can "undelegate" whenever you like. this increases stability of the network and also gives an incentive to pool operators to invest the time and hardware required to run a pool.
What is a stake-pool and how does it work? Cardano.org FAQ on the issue goes into much more detail
A stake pool is where the computing power of the network takes place. During ITN there was 1200 registered stake pools while 300 were creating blocks. You can manage your own stake-pool or delegate your ADA to an already registered pool. Rewards are determined by the protocol, however the pool may elect to charge fee Percentages, or flat rate fee to upkeep their pool.
Can I Stake my ADA right now? The staking testnet has closed, If you participated in the Incentivised Test Net and earned rewards, instructions to check the balance are here.
However if you have just purchased some or it was held on an exchange, then you will need to wait until the Shelley mainnet launch happening at the end of July 2020.
Where do I stake my ADA? Daedalus Flight wallet, and Yoroi Wallet (as a chrome extension) are the current best options. Adalite and several other third-party wallets also exist. Coinbase will also allow staking as a custodial service, and many exchanges may offer “staking as a service” so you can leave your coins on the exchange and still earn rewards if you enjoy trading. I do not recommend leaving coins on an exchange unless you are actively trading.
What are the staking rewards now and what can I expect on a return in the future? The Incentivised Test Net (ITN) Delivered 10%-15%pa returns on average. The future of staking will most likely be lower, but will depend on the amount of ADA staked across the network and the amount of network traffic.
Check https://staking.cardano.org/en/calculato for a clearer picture.
what is a Pledge? To stop one person operating many pools, the rewards that a pool earns will vary depending on the amount of personal ADA they “pledge” to open the pool. This means that 50 pools with a 1,00ADA pledge each will be overall less profitable than 1-2 pool with the max ADA pledge (unknown but likely around 300k). Even if the 50 pools have the same over stake delegated by other users and have a better chance of being selected to close a block, the 50 pools may receive lower rewards.. (at least that is the theory)
Who is IOHK? IOHK is a for-profit software engineering company founded by CEO Charles Hoskinson and Jeremy Wood in 2015 that has taken a scientific approach to the development of blockchain. IOHK started with “first principles” and looked at questions like “what is a blockchain” and “what should a blockchain be able to do” rather than accepting the established paradigm of Bitcoin and Ethereum. IOHK was originally Input Output Hong Kong, but is now Input Output Global and is based in Wyoming USA employing over 230 staff. IOHK has established research labs in several universities in order to complete the Cardano project, and is also developing Ethereum Classic, Atala, Mantis and possibly other Blockchain related programs and infrastructure.
Who is Charles? Charles Hoskinson is an early adopter of cryptocurrencies, American entrepreneur and cryptocurrency specialist. Charles Co-founded Ethereum with Vitalik Buterin and 5-8 others, However he only worked on that project for approximately six-months. Charles is now the CEO of IOHK and the director of The Bitcoin Education Project.
Why isn’t ADA on coinbase? Cardano and coinbase have recently connected in a big way. With IOHK turning over all their ADA to the custodial services of Coinbase. This means that Cardano and Coinbase have been working together for some time and there is a strong partnership forming. Staking and cold storage will be available and trading on Coinbase will most likely become available after the release of Shelley (although no official word yet)
Why Doesn’t Cardano have a Wikipedia Page? Wikipedia has strict guidelines on what can be turned into an article. As there has been no coverage of Cardano from mainstream media or “noteworthy” sources, there is no article yet. Wikipedia will also not accept sources from IOHK as they are not considered “reliable” and must come from a third party. This will most likely change soon.
Cardano does have a dedicated community driven wiki
https://cardanowiki.info/wiki/Home
What is Atala and why do I care?*
Atala is a suite of services being developed on top of the cardano blockchain by IOHK that focusses on credential certification, for things like education, work history and degrees (Atala Prism). Product counterfeiting protection through registering products on a blockchain and create taper-proof provenance. This does not only apply to Gucci handbags, but also medication, art, and anything that can be counterfeited (Atala Scan). As well as supply chain tracking to see issues and inefficiencies with greater transparency(Atala Trace).
Im new, how much is a good investment?
Cardano is still a speculative market and although there is amazing potential here, it is still only potential. When investing in any High risk market like Crypto, only every invest what you are willing to lose. Cardano may be testing the 10c barrier now. But in March it dumped to 1.7c. And if you suddenly need your money back during the dump then you are out of luck. Do your research before you FOMO in. Start with a small amount and send it between wallets and exchanges to understand how the system works. Store your private keys offline (or online cloud service but encrypted) with a method that is unlikely to be damaged AND have multiple copies. So in the case of a house fire or a blow to the head, or the cloud service being shutdown/destroyed, you do not lose your money.

Why choose Bitcoin Cash?

Some of you might be coming to this sub, and wondering why so many people support Bitcoin Cash. This is directly answered in the pinned FAQ, and also briefly goes over the history of the sub. Now onto why Bitcoin Cash has huge potential when it comes to changing the world:
Bitcoin Cash was created with the purpose of bringing economic freedom to everyone all across the globe. With the current banking, financial, and payment systems, there are many issues when it comes to the usability of money. These issues are:
- Sending money across the globe without having to pay high fees (percentage fees), and waiting days or even weeks for your transfer to go through
- Having payment options like Visa and Mastercard that help deal with high-volume business, but having to pay a flat fee ($0.15), and a fee of 2%-3% per purchase
- Having full control over your money, so the government can't devalue your savings by printing more money for their personal interests
- Being able to use your money however you like, without having to get permission from an intermediary, middleman, or financial institution
- Being able to know how much money will be circulating at any given time in the future
- Paying high fees (4%+) for converting currency when travelling
Let's take a look at how Bitcoin Cash solves these problems:
Remittance
When it comes to sending money across the globe from one bank account to another, often times the fees will be very high because when your bank is sending money, it has to go through several intermediary banks that each take from the initial amount of money, making the process slow, and expensive. Currently, Western Union is advertising "free" transfers of currency across the globe. Seems like a good deal, right? Well here's the thing: they're tricking you into thinking that transfers are free when they're actually making money off of the exchange rate. We believe that money (digital cash) should be as frictionless as possible, and that a user shouldn't have to deal with transfer fees, and have to get permission to transfer their money from one bank to another. Currently, the fees on Bitcoin Cash are only $0.0007, and we plan on keeping them that low.
Payment Systems
When it comes to traditional payment systems, like Visa, Mastercard, and American Express, credit card companies often charge a 2%-3% fee on every transaction that takes place, and a transaction can take anywhere from 24-36 hours to confirm, and go into a merchant's bank account. These payment systems are both slow and expensive. With Bitcoin Cash, your funds are available instantly for you to spend, but if you want to take extra security measures, you can always wait ~10 minutes for a confirmation to go through.
Control Over Your Own Money
With the banking system as we currently know it, one of the biggest problems is the lack of control your have over your own money. Every year, people are forced to pay taxes to politicians only to have their money basically wasted on providing effectively nothing to them. Bitcoin Cash solves this problem by giving you full control over your money. Making a wallet does not require anyone to give ID, personal information, or anything that could potentially lead to the government having any say in what you can do with your hard-earned money. Another issue with traditional currencies is the inflationary nature of them. This is another form of taxation that doesn't appear to be as bad as taxing, but it's just a different way of taking money from the hands of citizens. When the government prints more money, your savings get devalued, meaning that the government has effectively stolen money without physically "stealing" it. With Bitcoin Cash, the inflation relies on a purely mathematical system in which the maximum number of Bitcoins will always be 21 million. With mathematical certainty, you can always be sure of the exact supply of Bitcoins based on the block number. I made a graph that helps illustrate this with >99.99997% accuracy on how many Bitcoin Cash will be in circulation based on the block height. This works for Bitcoin, and Bitcoin SV too. You can check the accuracy by putting the block height/number in the brackets of the second expression.
Currency Conversion
Have you ever travelled to another country where you had to convert to the local currency in order to be able to use it? If so, you would've realized that conversion rates can often be very high, and it is impractical to do unless you're converting a large sum of money. Our idea is to increase merchant adoption so that Bitcoin Cash can have its own economy, so it doesn't matter where in the world you are, you can always use Bitcoin Cash, and not have to worry about conversion fees. If you want to "convert" to another currency, you can always use SLP tokens that will eventually come in a variety of local fiat currencies in the near future. Tether USDT is already planning to make SLP tokens too. This is also a great alternative if you aren't sure whether you want to put your money into crypto, and want to stick with fiat instead. Think of SLP tokens as "paper" tokens on top of Bitcoin Cash that can be sent and received for fractions of a penny!
How to use Bitcoin Cash for Buying Goods and Services
Right now, there are many ways you can use Bitcoin Cash, including local usage, and online usage. If you want to see which merchants near you accept Bitcoin Cash, you can check using map.bitcoin.com and see which local merchants are accepting Bitcoin Cash. If you want to buy things online, you can use purse.io, and get 30% off on any Amazon purchase, so you contribute to the economy of growing Bitcoin Cash, and get a great deal for any item you want to buy!
TL;DR: Bitcoin Cash is sound money which you have full control over your own money, and allows you to send any amount of money, anywhere in the world, instantly, and practically for free. If you have any additional questions, feel free to comment.

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.

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.
