Technical: Taproot: Why Activate?

This is a follow-up on https://old.reddit.com/Bitcoin/comments/hqzp14/technical_the_path_to_taproot_activation/
Taproot! Everybody wants it!! But... you might ask yourself: sure, everybody else wants it, but why would I, sovereign Bitcoin HODLer, want it? Surely I can be better than everybody else because I swapped XXX fiat for Bitcoin unlike all those nocoiners?
And it is important for you to know the reasons why you, o sovereign Bitcoiner, would want Taproot activated. After all, your nodes (or the nodes your wallets use, which if you are SPV, you hopefully can pester to your wallet vendoimplementor about) need to be upgraded in order for Taproot activation to actually succeed instead of becoming a hot sticky mess.
First, let's consider some principles of Bitcoin.
I'm sure most of us here would agree that the above are very important principles of Bitcoin and that these are principles we would not be willing to remove. If anything, we would want those principles strengthened (especially the last one, financial privacy, which current Bitcoin is only sporadically strong with: you can get privacy, it just requires effort to do so).
So, how does Taproot affect those principles?

Taproot and Your /Coins

Most HODLers probably HODL their coins in singlesig addresses. Sadly, switching to Taproot would do very little for you (it gives a mild discount at spend time, at the cost of a mild increase in fee at receive time (paid by whoever sends to you, so if it's a self-send from a P2PKH or bech32 address, you pay for this); mostly a wash).
(technical details: a Taproot output is 1 version byte + 32 byte public key, while a P2WPKH (bech32 singlesig) output is 1 version byte + 20 byte public key hash, so the Taproot output spends 12 bytes more; spending from a P2WPKH requires revealing a 32-byte public key later, which is not needed with Taproot, and Taproot signatures are about 9 bytes smaller than P2WPKH signatures, but the 32 bytes plus 9 bytes is divided by 4 because of the witness discount, so it saves about 11 bytes; mostly a wash, it increases blockweight by about 1 virtual byte, 4 weight for each Taproot-output-input, compared to P2WPKH-output-input).
However, as your HODLings grow in value, you might start wondering if multisignature k-of-n setups might be better for the security of your savings. And it is in multisignature that Taproot starts to give benefits!
Taproot switches to using Schnorr signing scheme. Schnorr makes key aggregation -- constructing a single public key from multiple public keys -- almost as trivial as adding numbers together. "Almost" because it involves some fairly advanced math instead of simple boring number adding, but hey when was the last time you added up your grocery list prices by hand huh?
With current P2SH and P2WSH multisignature schemes, if you have a 2-of-3 setup, then to spend, you need to provide two different signatures from two different public keys. With Taproot, you can create, using special moon math, a single public key that represents your 2-of-3 setup. Then you just put two of your devices together, have them communicate to each other (this can be done airgapped, in theory, by sending QR codes: the software to do this is not even being built yet, but that's because Taproot hasn't activated yet!), and they will make a single signature to authorize any spend from your 2-of-3 address. That's 73 witness bytes -- 18.25 virtual bytes -- of signatures you save!
And if you decide that your current setup with 1-of-1 P2PKH / P2WPKH addresses is just fine as-is: well, that's the whole point of a softfork: backwards-compatibility; you can receive from Taproot users just fine, and once your wallet is updated for Taproot-sending support, you can send to Taproot users just fine as well!
(P2WPKH and P2WSH -- SegWit v0 -- addresses start with bc1q; Taproot -- SegWit v1 --- addresses start with bc1p, in case you wanted to know the difference; in bech32 q is 0, p is 1)
Now how about HODLers who keep all, or some, of their coins on custodial services? Well, any custodial service worth its salt would be doing at least 2-of-3, or probably something even bigger, like 11-of-15. So your custodial service, if it switched to using Taproot internally, could save a lot more (imagine an 11-of-15 getting reduced from 11 signatures to just 1!), which --- we can only hope! --- should translate to lower fees and better customer service from your custodial service!
So I think we can say, very accurately, that the Bitcoin principle --- that YOU are in control of your money --- can only be helped by Taproot (if you are doing multisignature), and, because P2PKH and P2WPKH remain validly-usable addresses in a Taproot future, will not be harmed by Taproot. Its benefit to this principle might be small (it mostly only benefits multisignature users) but since it has no drawbacks with this (i.e. singlesig users can continue to use P2WPKH and P2PKH still) this is still a nice, tidy win!
(even singlesig users get a minor benefit, in that multisig users will now reduce their blockchain space footprint, so that fees can be kept low for everybody; so for example even if you have your single set of private keys engraved on titanium plates sealed in an airtight box stored in a safe buried in a desert protected by angry nomads riding giant sandworms because you're the frickin' Kwisatz Haderach, you still gain some benefit from Taproot)
And here's the important part: if P2PKH/P2WPKH is working perfectly fine with you and you decide to never use Taproot yourself, Taproot will not affect you detrimentally. First do no harm!

Taproot and Your Contracts

No one is an island, no one lives alone. Give and you shall receive. You know: by trading with other people, you can gain expertise in some obscure little necessity of the world (and greatly increase your productivity in that little field), and then trade the products of your expertise for necessities other people have created, all of you thereby gaining gains from trade.
So, contracts, which are basically enforceable agreements that facilitate trading with people who you do not personally know and therefore might not trust.
Let's start with a simple example. You want to buy some gewgaws from somebody. But you don't know them personally. The seller wants the money, you want their gewgaws, but because of the lack of trust (you don't know them!! what if they're scammers??) neither of you can benefit from gains from trade.
However, suppose both of you know of some entity that both of you trust. That entity can act as a trusted escrow. The entity provides you security: this enables the trade, allowing both of you to get gains from trade.
In Bitcoin-land, this can be implemented as a 2-of-3 multisignature. The three signatories in the multisgnature would be you, the gewgaw seller, and the escrow. You put the payment for the gewgaws into this 2-of-3 multisignature address.
Now, suppose it turns out neither of you are scammers (whaaaat!). You receive the gewgaws just fine and you're willing to pay up for them. Then you and the gewgaw seller just sign a transaction --- you and the gewgaw seller are 2, sufficient to trigger the 2-of-3 --- that spends from the 2-of-3 address to a singlesig the gewgaw seller wants (or whatever address the gewgaw seller wants).
But suppose some problem arises. The seller gave you gawgews instead of gewgaws. Or you decided to keep the gewgaws but not sign the transaction to release the funds to the seller. In either case, the escrow is notified, and if it can sign with you to refund the funds back to you (if the seller was a scammer) or it can sign with the seller to forward the funds to the seller (if you were a scammer).
Taproot helps with this: like mentioned above, it allows multisignature setups to produce only one signature, reducing blockchain space usage, and thus making contracts --- which require multiple people, by definition, you don't make contracts with yourself --- is made cheaper (which we hope enables more of these setups to happen for more gains from trade for everyone, also, moon and lambos).
(technology-wise, it's easier to make an n-of-n than a k-of-n, making a k-of-n would require a complex setup involving a long ritual with many communication rounds between the n participants, but an n-of-n can be done trivially with some moon math. You can, however, make what is effectively a 2-of-3 by using a three-branch SCRIPT: either 2-of-2 of you and seller, OR 2-of-2 of you and escrow, OR 2-of-2 of escrow and seller. Fortunately, Taproot adds a facility to embed a SCRIPT inside a public key, so you can have a 2-of-2 Taprooted address (between you and seller) with a SCRIPT branch that can instead be spent with 2-of-2 (you + escrow) OR 2-of-2 (seller + escrow), which implements the three-branched SCRIPT above. If neither of you are scammers (hopefully the common case) then you both sign using your keys and never have to contact the escrow, since you are just using the escrow public key without coordinating with them (because n-of-n is trivial but k-of-n requires setup with communication rounds), so in the "best case" where both of you are honest traders, you also get a privacy boost, in that the escrow never learns you have been trading on gewgaws, I mean ewww, gawgews are much better than gewgaws and therefore I now judge you for being a gewgaw enthusiast, you filthy gewgawer).

Taproot and Your Contracts, Part 2: Cryptographic Boogaloo

Now suppose you want to buy some data instead of things. For example, maybe you have some closed-source software in trial mode installed, and want to pay the developer for the full version. You want to pay for an activation code.
This can be done, today, by using an HTLC. The developer tells you the hash of the activation code. You pay to an HTLC, paying out to the developer if it reveals the preimage (the activation code), or refunding the money back to you after a pre-agreed timeout. If the developer claims the funds, it has to reveal the preimage, which is the activation code, and you can now activate your software. If the developer does not claim the funds by the timeout, you get refunded.
And you can do that, with HTLCs, today.
Of course, HTLCs do have problems:
Fortunately, with Schnorr (which is enabled by Taproot), we can now use the Scriptless Script constuction by Andrew Poelstra. This Scriptless Script allows a new construction, the PTLC or Pointlocked Timelocked Contract. Instead of hashes and preimages, just replace "hash" with "point" and "preimage" with "scalar".
Or as you might know them: "point" is really "public key" and "scalar" is really a "private key". What a PTLC does is that, given a particular public key, the pointlocked branch can be spent only if the spender reveals the private key of the given public key to you.
Another nice thing with PTLCs is that they are deniable. What appears onchain is just a single 2-of-2 signature between you and the developemanufacturer. It's like a magic trick. This signature has no special watermarks, it's a perfectly normal signature (the pledge). However, from this signature, plus some datta given to you by the developemanufacturer (known as the adaptor signature) you can derive the private key of a particular public key you both agree on (the turn). Anyone scraping the blockchain will just see signatures that look just like every other signature, and as long as nobody manages to hack you and get a copy of the adaptor signature or the private key, they cannot get the private key behind the public key (point) that the pointlocked branch needs (the prestige).
(Just to be clear, the public key you are getting the private key from, is distinct from the public key that the developemanufacturer will use for its funds. The activation key is different from the developer's onchain Bitcoin key, and it is the activation key whose private key you will be learning, not the developer's/manufacturer's onchain Bitcoin key).
So:
Taproot lets PTLCs exist onchain because they enable Schnorr, which is a requirement of PTLCs / Scriptless Script.
(technology-wise, take note that Scriptless Script works only for the "pointlocked" branch of the contract; you need normal Script, or a pre-signed nLockTimed transaction, for the "timelocked" branch. Since Taproot can embed a script, you can have the Taproot pubkey be a 2-of-2 to implement the Scriptless Script "pointlocked" branch, then have a hidden script that lets you recover the funds with an OP_CHECKLOCKTIMEVERIFY after the timeout if the seller does not claim the funds.)

Quantum Quibbles!

Now if you were really paying attention, you might have noticed this parenthetical:
(technical details: a Taproot output is 1 version byte + 32 byte public key, while a P2WPKH (bech32 singlesig) output is 1 version byte + 20 byte public key hash...)
So wait, Taproot uses raw 32-byte public keys, and not public key hashes? Isn't that more quantum-vulnerable??
Well, in theory yes. In practice, they probably are not.
It's not that hashes can be broken by quantum computes --- they're still not. Instead, you have to look at how you spend from a P2WPKH/P2PKH pay-to-public-key-hash.
When you spend from a P2PKH / P2WPKH, you have to reveal the public key. Then Bitcoin hashes it and checks if this matches with the public-key-hash, and only then actually validates the signature for that public key.
So an unconfirmed transaction, floating in the mempools of nodes globally, will show, in plain sight for everyone to see, your public key.
(public keys should be public, that's why they're called public keys, LOL)
And if quantum computers are fast enough to be of concern, then they are probably fast enough that, in the several minutes to several hours from broadcast to confirmation, they have already cracked the public key that is openly broadcast with your transaction. The owner of the quantum computer can now replace your unconfirmed transaction with one that pays the funds to itself. Even if you did not opt-in RBF, miners are still incentivized to support RBF on RBF-disabled transactions.
So the extra hash is not as significant a protection against quantum computers as you might think. Instead, the extra hash-and-compare needed is just extra validation effort.
Further, if you have ever, in the past, spent from the address, then there exists already a transaction indelibly stored on the blockchain, openly displaying the public key from which quantum computers can derive the private key. So those are still vulnerable to quantum computers.
For the most part, the cryptographers behind Taproot (and Bitcoin Core) are of the opinion that quantum computers capable of cracking Bitcoin pubkeys are unlikely to appear within a decade or two.
So:
For now, the homomorphic and linear properties of elliptic curve cryptography provide a lot of benefits --- particularly the linearity property is what enables Scriptless Script and simple multisignature (i.e. multisignatures that are just 1 signature onchain). So it might be a good idea to take advantage of them now while we are still fairly safe against quantum computers. It seems likely that quantum-safe signature schemes are nonlinear (thus losing these advantages).

Decentr ($DEC) - foundational cross-chain and cross-platform DeFi protocol

  1. SUMMARY
Decentr is a protocol designed to make blockchain/DLT mainstream by allowing DeFi applications built on various blockchains to “talk to each other”. Decentr is a 100% secure and decentralised Web 3.0 protocol where users can apply PDV (personal data value) to increase APR on $DEC that users loan out as part of of our DeFi dLoan features, as well as it being applied at PoS when paying for stuff online. Decentr is also building a BAT competitor browser and Chrome/Firefox extension that acts as a gateway to 100% decentralised Web 3.0
Allows DeFi Dapps to access all Decentr’s dFintech features, including dLoan, dPay. Key innovation is that the protocols is based on a user’s ability to leverage the value of their data as exchangeable “currency”.

A fee is charged for every transaction using dPay whereby an exchange takes place between money (fiat and digital) and data, and vice versa, either as part of DeFi features or via a dApp built on Decentr. They are launching pilot programmes in the following industries:
  1. Banking/PSP Industry: On Product launch, due to Decentr’s powerful PSP connections (including the worlds #2 PSP by volume), a medium-scale pilot program will be launched, which will seed the network with 150,000 PSP customers in primarily the Spanish/LAC markets, generating revenue from day one.
  2. “Bricks and Mortar” Supermarket/Grocery Industry: Decentr aims to ensure the long-term competitiveness of “bricks and mortar” supermarkets against online-only grocery retailers, such as Amazon, by a) building secure tech that allows supermarkets to digitise every aspect of their supply chains and operational functions, while b) allowing supermarkets to leverage this incredibly valuable data as a liquid asset class. Expected revenue by Year 5: $114Mn per year.
  3. Online Advertising Industry: Decentr’s 100% decentralised platform credits users secure data with payable value, in the form of PDV, for engaging with ads. The Brave browser was launched in 2012 and in 8 years has reached over 12 million monthly active users, accented by as many as 4.3 million daily active users.
  4. TOKEN $DEC AND SALE
Decentr recently complete their token sale on a purchase portal powered by Dolomite where they raised $974,000 in 10 minutes for a total sale hardcap of 1.25M. The $DEC token is actively trading on multiple exchanges including Uniswap and IDEX. Listed for free on IDEX, Hotbit, Hoo, Coinw, Tidex, BKex. Listed on CoinGecko and Coinmarketcap. Listed on Delta and Blockfolio apps.

Random idea: USL, but for Bitcoin addresses

This is my rough idea for a Bitcoin change that would allow for a bit more fraud protection. I might write up a BIP later if I get around to actually nailing it down.
For those unaware, the Universal Scammer List (USL) is a page dedicated to keeping track of the usernames of scammers on Reddit. Basically, if you want to conduct a transaction with someone on Reddit, you should first check if they're listed as a known scammer.
My idea is to do the same with Bitcoin addresses. A decentralised database of blacklisted addresses would be kept by anyone running a full node. Any funds in the blacklisted addresses are deemed worthless.
For example, address A gets listed for hacking into an exchange and stealing coins. Any funds held by address A would be deemed worthless. If they send 10 BTC to address B, then the network would remember that address B has 10 BTC that is worthless. If address B originally had 5 BTC and was sent 10 BTC by address A, they would have 15 BTC, but the bottom 10 BTC would be deemed worthless. If address B sends 2 BTC to address C, then C receives 2 good BTC and B is left with 3 good BTC and 10 blacklisted BTC, but if B sends another 4 BTC to address D, then D would receive 3 good BTC and 1 worthless BTC, and the network would now remember that D has 1 worthless Bitcoin. Therefore, before accepting the transaction as payment for something, they would have to check to make sure that they are not receiving worthless blacklisted coins.
Miners could also choose to selectively refuse to mine transactions involving blacklisted BTC because any miners' fees collected from such a transaction would be blacklisted as well. This could mean someone trying to send blacklisted BTC is essentially broadcasting a transaction with a 0 sat/byte fee rate, meaning their transaction would probably be stuck in the Mempool for quite a long time, if not forever if miners refuse to mine it.
Whenever someone wants an address blacklisted, they would announce it to the public via any mechanism, and anyone keeping a full node can decide whether or not to blacklist the address. Therefore, anyone who disagrees with the blacklisting is free to accept the coins at face value or mine them into a block. If you don't agree with the evidence presented, then you are free to not blacklist them. Therefore, contested coins would only be accepted as valid payment by those who think the coins should have never been blacklisted in the first place.
This system would not be meant to help every single person who gets scammed with Bitcoin, but it would discourage large scale wholesale Bitcoin fraud. It would be ridiculous to expect all full-node maintainers to become arbitrators of all disputes, and consensus would never be reached on half of the transactions being processed. Node operators would also ideally not have to remember as many transactions involving blacklisted coins because miners would refuse to mine them (transaction fees collected would be in blacklisted coins), meaning they'd be stuck in the Mempool for long periods of time, reducing the speed at which they can be moved around, if at all. So the ledger of blacklisted coins would not have to be updated extremely often. Blacklisting would only happen for really big scams involving tens or hundreds of Bitcoin, like if an exchange got hacked or something.
Scams have effectively less than an hour to be discovered. 10 minutes for the deposit into the address in question, and more, depending on how many block confirmations something must have before others will accept it for transactions sell goods for it. Therefore, if a merchant requires 3 block confirmations, then they would give 40 minutes for the address to be blacklisted. If the buyer's address is blacklisted before the transaction to the merchant gets 3 block confirmations, the merchant would realise they've been sent blacklisted coins and not ship the goods. 40 minutes isn't a lot of time, but it's better than nothing.
This has the additional effect of encouraging people to wait for more confirmations. For low-value transactions, the risk is nominal because even if you were sent worthless coins, you're probably only out the price of a coffee. But if you're selling a house, you might want to wait for even more block confirmations.
Money sent around too much could be deemed "too late to blacklist" if there is a risk that it would result in too many innocent people's Bitcoin getting blacklisted.
This system doesn't refund the Bitcoin of victims, so poor security practices would still be punished by a loss of coins, but criminals would not be rewarded for their efforts either. The lack of reward (or the risk of a lack of reward) would hopefully make people less inclined to try and pull off the type of big scams that are giving Bitcoin a bad reputation!

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.
www.Cardano.org www.emurgo.io https://cardanofoundation.org/en/
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.

6 Extraordinary Salespeople.

Good news, your request has been approved! One of the Salespeople is willing have you as a customer! Alas, due to union rules, only one of the Salespeople can work with each customer, so you’ll have to choose one. Once you’ve chosen, you can contact them anytime- just ask and they’ll step from the air wherever you are.
The Salespeople will haggle, but they’re pretty good at it- you’re unlikely to get more then a small decrease in cost, and will probably be haggled up. They won't be your friend, they won’t help you in any way other then making a sale, and will avoid answering any questions about what they are or where they came from (except the Knowledge Broker, but you’ll have to pay through the nose for that one). They are also much more powerful then they seem, and have access to abilities far beyond those obviously visible- any attempt to attack, rob, scam or coerce them will fail at best.
Anyway! Here they are! Choose one to work with!
  1. The Death Merchant: She’s young and thin. 20 at most, with the nervous, overly friendly look of someone trying to make their first sale. In a bright suit and bright smile, she explains. She makes people die. She’s not a hitman, you understand. She just makes people die. Give her a name and description and they’ll die the next day. Default is a stroke but if you want to pay a bit more you can choose a preferred method of death. Can’t be traced back to you, can’t be protected against, can't be survived. No she’s not heard of “Death Note”, she’s never really been much of a reader. What does she want in exchange? Time. Specifically, yours. Kill off some randomer with a stroke, you’ll only age a few months. But the more “important” someone is (that is, the bigger knock-on effects their death will have) and the more elaborate the cause of death, the more time is lost. Killing a world leader is about a decade. She notices you don’t have a lot of years, so she’ll inform you that her branch is looking for freelancers. That is, if you personally kill someone, she can give you some time for it! Same rules. Kill some nobody on the street and gain three months, kill a world leader and you’ll become a decade younger. She grins that bright smile as you notice the grass she stood on has withered away. Kill anyone you want and live forever! What a bargain, huh? Shake her hand and let’s get started!
  2. The Body Crafter: He’s in his 50s. Dressed casually, blunt and straightforward. He’s not going to give you his sales pitch. He’s just going to tell you what he makes. Bodies. He looks over yours and sighs. You got one of those evolution-designed ones, didn’t you? They seem cheap but they’ll give out on you. Here, he’ll fix it. He can make you a new body. All the way up from simply cosmetically different to superhuman. He’s very good at your job and honestly, given the junker you’re in now, he’ll only bill you raw materials. Compassionate reasons, you see. All you have to do bring him some flesh. A minor change- skin or eye or hair color, a bit smaller or taller? That’ll be maybe a small animal. A dog or pig for something like healing a chronic disease or a true sex change. Something like a cow or horse for making you younger, or improving your strength or speed or intelligence or something a reasonable amount. If you want peak human abilities, or an ability an animal has? That’ll be a person. Maybe 2, if it’s a really rare trait. You want something superhuman? That’ll be a lot of people. Depends on how powerful you want to be. Try and get some kind of kryptonian bullshit and you’ll need to depopulate a large city. He won’t lie to you: these animals and people are gonna die. Horribly. He’ll want them restrained when you’re giving them to him- he’s already doing you a favor, he’s not going to beat them into submission for you. Just give him the design of your new body and he’ll tell you what he needs.
  3. The Knowledge Broker: Sometimes, she’s so old she’s barely breathing. Sometimes, she’s so young she needs help talking. Sometimes she’s a teen, sometimes a young woman, sometimes middle aged. But always she has that faint smile and piercing gaze. She leads with the point. She knows everything. Any secret, any knowledge, any fact. She knows it. But she won’t give it for free. You see, there’s only one thing she doesn’t know. And that’s experiences. She can look at two lovers and tell you every opinion they have on the relationship, tell you what neurons are firing and what hormones are being released. But she doesn’t know what it’s like to be in love. So she wants your memories. She’ll just pluck them out of your head. The harder to obtain your knowledge is, the more important the memory has to be. Trivia you could get away with your trip to the supermarket. Classified information you might need to give up the memory of your first kiss. Grand secrets of the universe might need an entire childhood. She’ll take traumatic experiences- after experiencing nothing, even pain is better- but she prefers pleasant memories. Incredibly happy memories are worth much more, while miserable ones are worth less. A truly horrific experience will be near worthless, I’m afraid. She looks at you. Well? She’s an old woman (for now). She’s waiting. Are you in or not?
  4. The Money Giver: You'd barely notice this person. You can’t tell their sex, their race, their age. They’re average height, average weight, neither ugly or attractive. They talk in a voice utterly lacking emotion or accent, and explain that they have realized what humans really value. “Money”. They will give you “money”. They will give you a lot of money, if you ask. Direct to your bank account, by default, but it you want it in cash or cheque or gold or bitcoin or something they’ll provide. They almost show a hint of smugness when they confirm the taxmen of your world have no hope of exposing them. It’ll be fully laundered. What they want is control. They’ll take control of your body for a bit. They promise not to kill anyone directly or harm your body. For a few hundred, it may only be for an hour. A thousand might get them a day. A million will get them six months. A billion will get them a decade. Of course, richer you are, the better your odds of dealing with the aftermath once you get your body back. You have traded control of your life for money before. Do so again. Sign the contract.
  5. The Dream Author: he’s rail thin, heavily scarred, scribbling in a book as you speak. It takes him clear effort to stop and look up at you to begin his pitch. How would you like to visit one of his stories? It’ll be perfectly realistic, and it can feel like up to a decade. And he can write you however you want. He doesn’t judge, he’s written stories for all kinds of people. You wanna be a brutal god-king, crushing all opposition? You wanna be a hero who saves millions? You wanna just fuck? He prides himself on being a multi-genre writer. Whatever you provide, he can work with. It’s not real, of course. After the decade, you’ll wake where you were, only a few seconds having passed, as if it never happened. You’ll remember it all, don’t worry. All it costs is something you significantly emotionally value. Maybe an precious photo or something. Artists can’t be choosers. How long does it take to go onto pets or people? Well, depends on how often you enter a story, and how long it takes you to run out. If you're scared of spiraling, he’ll offer you a deal. Pay up front- destroy every object, kill every person, burn everything you care about- and he’ll put you in a story permanently. For as long as you subjectively like, in whatever world you like. If the cost really upsets you, he’ll make you imaginary versions of the people you love. You can do that, in his stories. You can do anything in his stories.
  6. The Luck Trader. They’re androgynous and beautiful, dressed delicately. They’re always grinning, and never still. They talk musically and never touch iron. They have a sack, and inside are tokens. Tokens of luck. Lucky in love? Lucky in money? Lucky in health? Whatever area you want, they can give it to you. Just have the token on you, and watch the luck flow towards you. It’s not perfect- this isn’t “winning lottery ticket rains down from the sky” luck- but things will go your way far more often then would otherwise be the case. It’s a boost, but it’s a hefty boost. If you take advantage, you could go very far in life. Of course, the tokens need activating. Just choose someone to activate it. It has to be someone you know personally- not necessarily someone you like, or know well, but you need to have had at least one genuine conversation with them. And the Trader will take them away. They’ll just be gone. No-one will ever find them. And you will get your token. Buy as many tokens as you like! You just need to keep offering up people, and you’ll get as many lucky breaks as you want. Their eyes glitter with hunger as they speak. Just give them people and watch the doors of the world open before you. It's a bargain.

I am the creator of BitcoinDuLiban.org. I am on a mission to educate Lebanese about the importance and usefulness of Bitcoins in their lives. AMA

What is Bitcoin?

Bitcoin (₿) (ticker BTC)is an open source cryptocurrency. It is a decentralized cryptographic currency without a central bank or single administrator in control that can be sent from user to user on the peer-to-peer bitcoin network without the need for 3rd person in between like bank, or payment processor or institution all transaction processing and verification is carried out collectively by the network.
Find out more at http://www.bitcoinduliban.org/

Why Bitcoin is the future?

Bitcoin emerged in 2009 as more economies across the world started losing trust in the current banking model. Institutions that have been around longer than ourselves have changed very little throughout our lifetime. Not only does the lack of trust, and stagnant change of banks allow Bitcoin to thrive, but also the possibility of eliminating inflation. Bitcoin saw the opportunity to take the power out of the institutions and provide a better service, and the people responded. Bitcoin operates universally, meaning for the first time, there is a possibility of a global currency. With truly international currency possibilities for global economic growth, social equality, self-sovereignty is endless.

Why Bitcoin and not others?

It is a very good question, there at the moment of writing over 2000 projects and “coins” that emerged after Bitcoin. Many of them claim to be faster, better and more flexible than Bitcoin however very few have withstood the test of time or delivered their proposed product. The basic fundamentals of Bitcoin’s principle monetary policy are unprecedented, and by now, it is impossible to replicate its level of decentralization or network security, which is powered by a computer network as powerful as almost 12 trillion Intel Core i7 processors. Bitcoin also has the largest social / community strength. I would HIGHLY advise against investing or getting dragged into any project that claims superiority, I have single rule : if it says it's better than Bitcoin then its what we call “scam-coin” you will only get pulled in and lose your bitcoin/usd value causing a lot of pain and sadness . Sit down, read, learn and be patient, you will not miss out on anything over night and if something is rising in price quickly most likely it will crash as fast.

Does bitcoin have an applicable use in daily life or is it only for holding for future gains?

Bitcoin has taken over the cryptocurrency market. It’s the largest and most well-known digital currency today. Many large companies are accepting Bitcoin as a legitimate source of funds, you can use your Bitcoin at but not limited to : KFC, Burger King, Microsoft, AT&T , Expedia, Subway, Twitch, Virgin Galactic and many more just look it up. You can look up merc and services at https://spendabit.co/ So if you are living abroad, you can use your bitcoin just like any other known currency in addition there are Debit cards in collaboration with VISA network offers that are backed by Bitcoin making you able to pay with it anywhere in the world just with a swipe or tap.

As Lebanese in Lebanon, how can I buy or sell bitcoin ?

In Lebanon unfortunately we can not use our banking system to purchase bitcoin, there was a time where rain.bh an UAE based exchange was accepting Lebanese Cards, till it was stopped but give it a try we weren’t able to confirm all cards.
Therefore most common way to buy bitcoin in lebanon is using P2P which is person to person exchange, this can be through an international website such as localbitcoins.com or hodlhodl.com , all you gotta do is find a sell offer initiate transaction with seller , send him his payment using WesterUnion or Moneygram and once the seller receives payment your bitcoins will be released but make sure you use escrow service which ensures safety of your transaction therefore bitcoins you are buying are frozen for the seller and he can not retrieve them unless you fail to pay or run out of time window to pay. Another p2p way is through local bitcoin communities , there are plenty of traders willing to exchange with you however always ask for the reputation of the seller inside a group and never respond to private messages unless it is a confirmed reliable trader just to avoid losing and being scammed. Feel free to find out more about how to buy in Lebanon at http://www.bitcoinduliban.org/

If I have a bank account outside Lebanon, can I use bitcoin to transfer money from Lebanon to my bank account outside?

It is possible to transfer Bitcoin to an international account in the USA or EU for example, you would need to use recognized exchanges such as coinbase.com kraken.com and many others. It would be as simple as sending BTC to your coinbase account, converting to USD and withdrawing it to your account. However you must take few precautions, if you are sending a significant amount of BTC and converting it to USD you will need some kind of proof that these funds are yours otherwise you might get investigated for money laundering. So is it convenient to send ? I do not think so, if you managed to get what we call now in Lebanon “ Fresh USD” it would be much less of a hassle to simply initiate an international transaction.

Why would I want to send Bitcoin to my family or friends in Lebanon ?

This is where I believe BTC can shine for us, you can use exchanges as coinbase,kraken or any prefered place to purchase some bitcoin that can be transferred to your family wallet within minutes. Your family or friends can exchange bitcoin or part that is needed with local traders to LBP at desired exchange rate therefore you are not forced to exchange at rates given by WesterUnion, after which they will be able to do their daily purchases and mitigate inflation rates to some extent. You can send as little as $1 and the transaction costs less than $1 for any amount.

Why is the Bitcoin price so volatile ?

Indeed it can be, sudden swings of 20% both ways are considered normal if you look at daily data, however bitcoin since 2009 had only one trend which is upward, 80% chance is if you bought BTC at any moment in past 2 years is that you are on break even or positive not loss. Feel free to try this exercise by going to https://dcabtc.com/

Should I invest?

NO. Now since we got the short version of this, let me elaborate. By the end of the day it is a new class of an asset, the price is still in the discovery phase and it could cause a lot of pain and sleepless nights if you invest more than you can chew to possibly lose. No one can advice you what to do with your money and how to position them, however i highly encourage to read, educate yourself on money before investing in BTC a good start would be https://bitcoinduliban.org. Please ask more knowledgeable bitcoin users and double check sources , once you feel confident enough that you understand this monetary system you can try dipping your toes with small amounts and build your position from there. Just stay away from quick gains schemes such as “online mining” “cloud mining” and anything that offers 100% returns in a very short time, if it's too good to be true then it's a scam.

Scams, BE AWARE.

Due to our difficult situation we are being targeted by constant advertisement of potential new solutions using “newly developed cryptocurrencies“ , unfortunately such new technology does not exist and they are trying to take advantage of us by promising fake solutions.
Even Bitcoin can not provide you with a solution to your hard worked money being inaccessible in any Lebanese bank.
Here are few typical scam msgs:

RMT Fix Suggestion / Idea

If anything I hope the staff sees this and reads this.
First a change to punishment protocol.
Confirmed seller: Ban
Confirmed buyer: 3 day suspension, account wipe, next time ban. (Edit: it has been pointed out that wiping would permanently punish someone who was hit under a false positive and therefore struck)
Might be a hot take, but why not suspend? Allow people to learn from their mistakes. RMT is a bad thing to do, but is not on par with hacking, even if it enables hackers. RMT is normalized throughout online games and therefore is a problem in the gaming culture/community and can be changed. However, no company has been successful in removing RMT with these methods. So this is what I suggest.
  1. Restrict the players ability to bring in items that are not medical, food, combat or gear related. There is no reason to bring in a GP coin or Bitcoin that I am aware of and they have stated that they don't want you to bring your friends items. This would fix both problems. You could make an exception if the item is quest related. RMT sellers would have to find other items to drop, which may include guns and expensive pieces of gear but with that will come the risk of having to extract successfully with it, greatly increase the time it would take to deliver an item and greatly increase the price of virtual roubles to real US dollars. You would still be able to do a raid with your friend and exchange gear you found inside of that raid or on enemy players.
  2. Change the way the flea market works. Generally I am for a free market, but because of the rampant abuse of RMT sellers and buyers, this can no longer be the case. Every item has a set sell value and if sold by a vendor an inherent buy value. You could use the percentage of the depreciation of an item when you sell it vs when it is bought to find the value of all items IF they were sold by the vendor. You could take this value and allow it to be sold on the flea market for no more than 200% or 250% of that value. You can also make it so the barter value can also no exceed that percentage total as well. Nikita has said that he does not like the inflation of items and this would solve a lot of RMT issues, his issues with the market as well as price gouging. It would also slow down progression. If BSG is unhappy with the value of an item, they only need to tweak the sell value and it would scale with the set percentage for depreciation.
It is clear from the podcasts that Nikita has been on that they are devoting a lot of time to combat this issue. They could shut down the flea market for a week in order to put this system into place and work on the changing in raid issues as well and the game would be better for it. The supply and demand for these services will always be there and reluctantly I would say there is no alternative solution. Getting into a banning tug of war with buyers and sellers will only end with the draining of BSGs resources, which are precious towards the continuation of development. The only good thing to come out of soft banning accounts is that they purchase new accounts, but how many of those accounts are bought with stolen cards that are charged back.
As an American I am well aware of our infatuation with instant gratification and I believe that is also another source that fuels RMT. We want our gear now, we want it easy and we want it fast. Putting these measures in place would force players to play the way the game is intended to be played.
The only issue that I think cannot be solve currently is paid Sherpa services that are available online. I would say that the price you would pay to play with someone comes with the risk of losing all of your items to other players.
I know people do not like the idea of regulating the in game market as it will take roubles out of the pockets of those who are used to selling high value items legitimately, but it is a necessary evil for the betterment of the game as well as the sustainability and longevity of Tarkov.
Thoughts?

Ghosted by Coinberry, Frozen Withdrawal

TLDR: Withdrew bitcoin successfully twice. Tried again on May 26th and it has been frozen in "processing" for over 2 weeks and Coinberry has not responded. Support has disappeared and updates have stopped. 387 users affected on May 30th, 123 remain affected on June 5th, my issue is unresolved on June 10th. Funding confirmations requested by and sent to Coinberry on June 4th. Still no response.
First of all, Coinberry claims that there has been substantial delays for various reasons. They claim that they are having issues on their side pertaining to account verifications and increased traffic. Status updates were being posted to Coinberry's official status page, but have stopped since June 5th, and customer support email, chat, and phone are all down. The fishiest part however is that, according to their website, only 123 users of the 327 initially affected remained on June 5th. It is hard to believe that they managed to get through ~50 users a day and still have not been able to resolve my issue or AT LEAST respond to my emails. Another fishy part is that Coinberry claims they cannot see my funding on "their ledger" but they keep a "Receipt No." for every transaction in the activity log, which (along with the e-transfer confirmation emails), I sent back to Coinberry on June 4th.
As many others have posted, I've had this withdrawal stuck as "processing" for over 2 weeks. My issue is not with the initial delay. However, the issue is that their customer support seems to have disappeared. I have been trying to reach support through email for two weeks now. The only response I received was about a week ago, requesting for proof of the e-transfer confirmations relating to the transactions on my account. I replied, with the confirmations, within minutes and have not heard back since. I have sent several follow-up emails trying to reach support as well as message them on facebook, but still, there is still no response. The least Coinberry should do is provide each affected user with an expected timeline for resolution. The CEO posted a blog "addressing" the speculation around Coinberry's insolvency. Honestly, this blog seems worthless as it is essentially saying is that they are "having issues but not insolvent" so he is chalking it up to service issues and claiming that "the team is working to resolve it asap". If this really was the case, it would be nice to receive a response from support to confirm that the resolution is on way. On that blog it states that "you may need to re-verify" or there will be delays if you "used a different bank account (#1 reason)", but my account IS verified and I emailed support confirming the transactions. Still no response, so I am assuming it is not being resolved.
I had chosen Coinberry because I found it to be very easy-to-use and trustworthy (considering they boast their "PIPEDA/FINTRAC" compliance) and the platform seemed to be one of the best I had used personally. Now, I am posting here in hopes that others take caution before depositing any funds into Coinberry, as well as in hopes that they may respond to me here as it seems to be the only place where people have been able to contact support. Again, they WILL NOT RESPOND to any queries that I have tried, so think twice before depositing any funds (during this time, at least).
I do not think Coinberry is necessarily a "scam" or a "Quadriga 2.0" as many others are claiming, and I think that they may legitamitely be working to resolve the issue. However, the fact that customers need to resort to research and reddit to find answers about situations like these, combined with the sketchy stories of past crypto exchanges, has made me rather disappointed with Coinberry at this time. Right now is definitely a shaky time in terms of how trustworthy Coinberry really is/whether it is setting up for a Quadriga-type scenario.
I will update the thread if I receive a response from Coinberry support. Feel free to post your own experiences.
*Update (10/06/2020) - DM'd u/CoinberryOfficial, awaiting further response.
*Update (11/06/2020) - Received initial DM response saying the same thing as the email I received a week ago, awaiting for further contact.
*Update (12/06/2020) - No further response via reddit or email. Coinberry status page updated on 11/06/2020 "Mobile app versions prior to 111.8 (on iOS) and 1.11.8 (on Android) were decommissioned on June 11, 2020". Updates about upgrading a mobile app but nothing about numerous counts of delayed withdrawals and locked accounts? Still no email or DM response.
*Update (12/06/2020) - Contacted back by u/CoinberryOfficial stating "Hi apologies for the delay, on our end the withdrawal is indicated as processed and completed, can you kindly verify on your end?" but I have not yet received my withdrawal. Working through the issue over DM.
*Update (13/06/2020) - Working slowly with u/CoinberryOfficial but for now, I have been given the exact same answer as I was in the only email I have received from support in the 3 weeks since I tried to withdraw my mere 0.01989 BTC. The response I received was "No your withdrawal is currently still processed and will be sent out once we can locate the deposit that was credited to your account on may 15th. We are unable to locate the deposit made on may 15th , but can locate the second one made on may 26th. We do not require further verification but do require to verify on your end that it was not accidently blocked by your bank. For the security of your information we do kindly ask that you continue this correspondence with support via email." Now, I have to wait till monday because it is after office hours (like that means anything, been trying to reach them all week lol). This is frustrating because I have already sent proof and confirmations over a week ago of interac e-transfers, bank statements, and Coinberry activity, but the support team never replied. It makes no sense as to how it "cannot be located" because I had successfully withdrew all the BTC purchased from the funds on the 15th and simply hadn't funded it again until the 26th. Next update on 15/06/2020 -.-
*UPDATE (15/06/2020) - Still NO RESPONSE from support or u/CoinberryOfficial. Don’t know when I’m going to get my funds at this point, as on Reddit I was told this would be “resolved first thing Monday morning”. So disappointed.
*UPDATE (16/06/2020) - u/CoinberryOfficial responded this morning stating "Sorry for the delay, support will make contact with you shortly". 5 hours later, still no response. I am assuming "business hours" are also over for the day now too. Update posted by the CEO, full of bullshit from what I can tell, referring to these issues and stating "all hands on deck", "we doubled customer success staff" and worst of all "This meant getting customers’ funds to them promptly...our customer success team can monitor, in real time, what our customers may need and where an issue could arise, as well as being alerted to any potential customer service delays...has allowed our customer success team to ensure a seamless, consistent customer experience". Ridiculous.
UPDATE: As of today (25/06/2020), I have received my funds and the issue has finally been RESOLVED. Thanks to Barry from Coinberry support. Reached out on the websites live chat and seem to have gotten extremely lucky that Barry was there and remained online, chatting to me, until the issue was completely resolved. Although the delays throughout this whole month were a major issue, it is a relief that Coinberry does in fact seem to be resolving these issues.

Cardano FAQ - V2

Cardano FAQ
What is Cardano? Cardano is an open source highly secure "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 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 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 - 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.
Gen 2 was Ethereum and other smart-contract platforms that allow other coins to be built on top of their infrastructure. These coins can interact with others on the platform, but cannot interact with other platforms like Stella, Bitcoin, cardano - and so on. Also most Gen 2 blockchains are also using Proof of Work likes Bitcoin, which effects scaling.
Gen 3 blockchains are using Proof of Stake to ensure scaling, Sidechains to allow the platform to interact with other platforms, like ethereum and bitcoin, and also include smart contracts that are developer friendly.
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 working on Cardano 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. (from https://www.cardano.org/en/help-support/)
What is the difference between PoS and PoW? 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 the network agrees, then the transaction is validated. Proof-of-Work (PoW) happens when a miner solves 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.
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? A stake pool is where the computing power of the network takes place. Currently there are 1200 registered stake pools while 300 are 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? If you had ADA in a Yoroi or Daedalus wallet before November 2019 then yes, you can stake. However if you have just purchased some or it was held on an exchange, then you will need to wait until August 18 (hopefully) for pools to start creating blocks, and first staking rewards will be 5 days later.
Where do I stake my ADA? Daedalus Flight wallet - Or Daedalus ITN, and Yoroi Wallet (as a chrome extension) are the current best options.
What are the staking rewards now and what can I expect on a return in the future? At the moment the Incentivised Test Net (ITN) is delivering 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. However it should not be completely dissimilar from the ITN, with most speculating 6%-10%pa compounding weekly….at this point there is no solid answer
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 100 pools with a 10,00ADA pledge will be overall less profitable than 1 pool with 1,000,000 ADA pledge. (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, Atilia, Mantis and possibly other Blockchain related programs and infrastructure.
Who is Charles? Charles Hoskinson is an American entrepreneur and cryptocurrency specialist. Charles is often cited in the media as the Co-founder of Ethereum, but 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? There is no official word specifically as to why Cardano is not on Coinbase, However there prevailing theory is that Coinbase requires the coins to be decentralised. and as Cardano is still being developed, it will not be added Shelley is released, or possibly never, it is totally up to coinbase. However Charles did mention in an AMA that IOG has been working with many exchanges for the Shelley rollout.
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

Cardano FAQ
What is Cardano? - Cardano is an open source highly secure blockchain 3.0 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 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 when evaluating transactions. (https://support.bitkub.com/hc/en-us/articles/360006678892-What-are-the-two-layers-of-Cardano-)
IHOK has the contract with an undisclosed party to develop the project until the end of 2020, at which point the community may elect another - 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. Amongst 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.
Who is the team behind Cardano? There are three organisations that are contributing to the development of Cardano.

Finally, to determine the number of that blockchain’s confirmations that are equal to six Bitcoin confirmations in terms of the amount of work done, the platform monitors the amount of time required on the other blockchain when at its dollars per second value that is equal to the total cost. Trading & Investing Bitcoin Exchange Guide News While some services are instant or only require one confirmation, many Bitcoin companies will require more as each confirmation greatly decreases the likelihood of a payment being reversed. It is common for six confirmations to be required which takes about an hour. How many bitcoin confirmations are needed? Six confirmations are widely considered to be safe and secure enough to prove your transaction will be valid and permanent. The initial transaction block represents the first confirmation, and you’re advised to wait until five additional blocks are added, resulting in a six-link blockchain.
