  1. CashAddress - Open Source JavaScript Client-Side Bitcoin Cash Wallet Generator

    A Bitcoin Cash wallet is as simple as a single pairing of a Bitcoin Cash address with its corresponding private key. Such a wallet has been generated for you in your web browser and is displayed above.

    To safeguard this wallet you must print or otherwise record the Bitcoin Cash address and private key. It is important to make a backup copy of the private key and store it in a safe location. This site does not have knowledge of your private key. If you are familiar with PGP you can download this all-in-one HTML page and check that you have an authentic version from the author of this site by matching the SHA256 hash of this HTML with the SHA256 hash available in the signed version history document linked on the footer of this site. If you leave/refresh the site or press the "Generate New Address" button then a new private key will be generated and the previously displayed private key will not be retrievable. Your Bitcoin Cash private key should be kept a secret. Whomever you share the private key with has access to spend all the bitcoins associated with that address. If you print your wallet then store it in a zip lock bag to keep it safe from water. Treat a paper wallet like cash.

    Add funds to this wallet by instructing others to send bitcoins to your Bitcoin Cash address.

    Check your balance by going to blockchair.com and entering your Bitcoin Cash address.

    Spend your Bitcoin Cash by downloading one of the popular Bitcoin Cash p2p clients and importing your private key to the p2p client wallet. Keep in mind when you import your single key to a Bitcoin Cash p2p client and spend funds your key will be bundled with other private keys in the p2p client wallet. When you perform a transaction your change will be sent to another bitcoin address within the p2p client wallet. You must then backup the p2p client wallet and keep it safe as your remaining bitcoins will be stored there. Satoshi advised that one should never delete a wallet.

    New Features
    On Chain Scalability - Bitcoin Cash follows the Nakamoto roadmap of global adoption with on-chain scaling. As a first step, the blocksize limit has been made adjustable, with an increased default of 8MB. Research is underway to allow massive future increases.

    New Transaction Signatures - A new SigHash type provides replay protection, improved hardware wallet security, and elimination of the quadratic hashing problem.

    New Difficulty Adjustment Algorithm (DAA) - Responsive Proof-of-Work difficulty adjustment allows miners to migrate from the legacy Bitcoin chain as desired, while providing protection against hashrate fluctuations.

    Decentralized Development - With multiple independent teams of developers providing software implementations, the future is secure. Bitcoin Cash is resistant to political and social attacks on protocol development. No single group or project can control it. The bitcoin-ml mailing list is a good venue for making proposals for changes that require coordination across development teams.

  5. What is it?
    A simple, secure way to pay your everyday Australian bills (electricity, rego, phone, credit card etc) with bitcoin.

    How do I use it?
    Enter the biller and ref code from your bill
    Pay with bitcoin to the address provided
    Get a confirmation number instantly

    Who is using it?
    Lots of Australians. Check out some statistics.

    Are there any payment limits?
    Individual transactions are limited to a maximum of $1000 each due to ASIC regulatory requirements.
    However if you wish to pay a bill that totals more than $1000, that's perfectly ok. You can simply create two or more bills with the same payment details (use the "copy details to new bill" button to make this easier). This will work for all BPAY and Bank Account payments.
    Full details are in our disclosure document.

    Why is it called "Living Room of Satoshi"?
    Our company is named in honour of Satoshi Nakamoto, the mysterious and pseudonymous creator of bitcoin. Nobody really knows for sure who he is, or what he is doing now.
    But we like to imagine that when Satoshi has a bill to pay, he kicks back at the end of the day and pays it in his living room. Hence "Living Room of Satoshi"!

  6. A community-curated list of sites/merchants that accept Bitcoin Cash, a peer-to-peer electronic cash system.

    This site was built as a means to connect consumers and merchants, while spreading awareness and promoting global adoption of Bitcoin Cash. It is our hope that as time goes on, more and more sites will be accepting Bitcoin Cash as a fast and secure payment method, with the added benefits of low fees, no third-party, atop a very strong decentralized network.

    The community factor
    The site is open source, which allows for anyone to contribute, submitting new sites that either accept, or do not (yet) accept Bitcoin Cash. Please read our contribution guidelines to learn how to help. Any contributions are welcomed, and will be added once verified by others.

    The future
    Many believe that Bitcoin Cash is the true continuation of Satoshi's vision. We're committed to supporting this site in order to keep it updated with accurate information, as well as adding new features and functionality as the opportunity arises.

    Add a site if it's not listed by submitting a pull request, or creating an issue on the GitHub repo. Learn how to do either by reading our contribution guidelines.

  7. What is Coinmix?
    Coinmix is the first Bitcoin Cash coin mixer — a service to improve your privacy by breaking the link between you and your payment destination.

    How does it work?
    Coinmix has a large pool of pre-mixed coins. It puts your coins into the queue and uses the oldest coins in the pool to send your payment instead.

    It also combines multiple payments into a single large transaction, making it impossible to tell which input paid for which output.

    What is the "return address"?
    Return address allows you to break the amount. If you send 0.12345 and somebody receives 0.12345, it makes it easier to link those payments.

    You can instead send 0.12345 to your destination, but deposit 0.888 and return the rest (0.76455) back to your wallet.

    What is "delay"?
    You can delay your payment for a certain number of blocks.

    This allows you to send and return in different transactions, because the funds are always returned in the next mixing transaction, but sending will now be delayed.

    Adding a delay between your deposit and the final transfer makes it much harder to link your payments.

    What is the probability of me receiving any of my original coins?
    Our algorithm guarantees that no destination address will ever receive any of the deposits directly — the coins will always go through several mixing addresses first.

    What is "pool size"?
    It's the amount of pre-mixed coins available + all pending user transfers.

    If you want to help the mixer, you can increase the pool directly by donating BCC to our primary address:

    What is "prize" and "jackpot"?
    The mixer has a twist — it plays a little lottery with the fees to incentivise usage.

    Each mixing transaction collects all the fees for pending orders. It then adds part of it to the round prize and part to the jackpot. One user in the current round will win the prize (and maybe the jackpot) of the previous round. The round usually equals one block.

    Your chance of winning depends on the amount you send:

    This is done to incentivise people to mix amounts closer to the same value, making it harder to link payments.

    What fees does your service take?
    The fees are a bit random to improve privacy, but the average fee now is about 0.125% for 100+ BCC.

    If you send less, the fee will gradually rise all the way to approx. 50% for sending 0.001 BCC. For 1 BCC, for example, the average fee is 0.188% (0.00188 BCC).

    The fee is calculated based on the total (send + return) amount you move through the mixer.

    How exactly are fees distributed?
    Currently the fees are distributed like this:

    35% goes to investors.
    30% goes to the round prize.
    20% goes to the jackpot.
    10% goes into reserve.
    5% covers mixing transactions fees.
    What if I deposit less than asked?
    No problem, the system will tell you how much more you need to deposit and you can send another transaction.

    What if I deposit more than asked?
    To prevent cheating on fees, the system will not send any extra money you deposit along with your transfer.

    Any money above what was requested will be treated as a donation to increase the pool.

    Can I use the deposit address as a destination for yet another Coinmix transfer?
    No, such deposits will not be credited, so please don't do it.

    Who runs this service?
    Right now it's a "one-guy operation" :-)

    About me: as NxtChg I've been here for 3 years, in Bitcoin in general I was since the time Satoshi was still around. I ran nxtchg.com, then closed it and returned every single penny. Now I run Simcoin exchange and withdrawals are processed regularly. I am also trying to build my own coin (Simcoin). Some of my other projects are here.

    For any questions or suggestions about Coinmix you can reach me here: [email protected]

    What logs are kept?
    Orders are recorded in the database for the time it takes to process them. After 24 hours they are deleted automatically and the database record is overwritten with blank values. No IP's are stored in the database.

    You will also see the 'delete' button once the order is processed and can delete the database record immediately (don't forget to save the promise first).

    Currently the web server logs are enabled to monitor abuse, but they only link IP with order ID, which cannot be linked to your payment info without the database record.

    For law enforcement agencies: please do not contact us with requests to help with your investigations, since no information is kept that could assist you.

    Why didn't you make a trustless mixer like CoinShuffle?
    CoinShuffle (or CashShuffle) has some major drawbacks:

    1. You need to wait until enough people are willing to transact at the same time. This also means that the number of concurrent users will be less than in a mixer, where payments are spread out throughout the day.

    2. Your money must be present in the final transaction, which makes it easier to track, especially if there are not that many participants, compared to a mixer that does both — combines inputs and uses other people's money to pay for your transfers.

    3. CoinShuffle works if everybody sends the exact same amount, which limits you to fixed amounts (don't use any CoinShuffle service that allows arbitrary amounts — it makes it a lot easier to link your payments).

    What about Monero or ZCash?
    The problem with advanced, complex cryptography is that it might be broken at some point in the future. Complexity also means more chances for a critical bug, as indeed happened in Monero.

    A well-respected cryptographer released a tool called monerolink.com, which can link all transactions from 2014–2016 with 100% probability, and all transactions from 2016–2017 with probability depending on mixin size.

    This is a huge problem. Once such cryptography is broken, all the past transactions recorded on the public blockchain become linkable!

    A good mixer, on the other hand, destroys information irreversibly, making it next to impossible to link payments with any sort of reliability.

    Didn't companies like chainalysis.com "solve" mixers?
    You keep reading articles about how chain analysis "solved" mixers for the simple reason that these companies need to convince people that they did, and journalists being journalists will repeat anything said to them, without any kind of fact checking, sometimes even writing paid posts.

    The reality is — if the mixer is good (many people using it + large pool of coins), it becomes theoretically impossible to link payments.

    Here's a simple example: if Alice and Bob both send 1 BCC in the same transaction to Charlie and Dick, there is absolutely no way to tell who sent what to whom.

    But what about temporal analysis?
    Temporal analysis can be used when one wallet regularly sends coins to another wallet, and if the attacker figured out which addresses belong to each wallet.

    To make it harder, do this:

    Create your private wallet.
    Fill it up with one or two relatively large transactions (1-3 BCC). Set random delay.
    Use it for smaller transactions until it's empty.
    Throw it away and repeat.
    Have you thought about open sourcing it so we can have multiple people running these mixers?
    The quality of mixing greatly depends on: a) the amount of money in the pool, b) the number of people using it. So one big mixer would do a much better job. Several small mixers will ruin the whole point of joined transactions.

    But what if your single big mixer is a honeypot?
    The difference is that if you do trust the mixer, you get great mixing quality (and protection from retroactive linking in the future).

    If you don't and want to use the small mixers, you have no mixing quality at all, and all your payments are linked as well, only now publicly.

    If my mixer is a NSA honeypot, they will not go after regular people. They are after some serious crimes.

    Small mixers, on the other hand, produce poor-quality transactions recorded on the public blockchain, ready to be analysed by anyone.

    Are there any wallets that integrate coin mixing?
    Yes, I've integrated Coinmix into The Simplest Bitcoin Wallet: https://tsbw.io/bcc/

    How can I invest?
    Investments are private, 1 BCC minimum. Mixers are high-risk ventures, so we don't recommend general public to invest. If you are still interested, contact me to discuss it.

    35% of fees is distributed among investors proportionally to their share of the pool size. Dividends are paid automatically, once a minimum amount is reached. First few weeks expect erratic times as usage grows.

    Investors agree to accept any losses that might result from a server hack or bugs in the software. You can withdraw your investment at any time (allow up to 24 hours to process).

    Can I help any other way?
    Spread the word! The quality of mixing service depends on the number of people using it.

    How can I improve my privacy further?
    Here are some tips:

    Use VPN or TOR to hide your IP.
    Use incognito mode in the browser or at least clear your browsing history.
    Use a different wallet for mixed coins.
    Pass your payments through large exchanges before and after the mixer.
    Always use return address and random delay.
    Send several smaller transfers instead of a large one.
    Pick round amounts: 0.01, 0.1, 2, 5, etc.
