Bitcoin Cash is a permissionless, open network. It empowers you to engage with your fellow human beings without intrusion. As usage grows, old power structures will erode while fresh ideas blossom. It may help usher in the greatest peaceful revolution the world has ever known. The network fee for a typical Bitcoin Cash transaction is less than one penny.

If you want to convert your BCH into fiat currency, such as US dollars, you can do that through merchant processors for a cost that is still much lower than credit card processing. Unlike credit cards, there are never any automatic voids, refunds, chargebacks, or other unexpected fees.

Fraud protection is built into the system with no cost to the merchant. A growing number of patrons are choosing Bitcoin Cash as a preferred payment method. They favor merchants who offer this payment option and actively seek them out.

By accepting Bitcoin Cash, merchants can gain free listings in website and app directories, gaining even more customers. They can also take advantage of this new trend and generate press for their business. In , he released the first bitcoin software that powered the network, and it operated smoothly for several years with low fees, and fast, reliable transactions.

Unfortunately, from to , Bitcoin became increasingly unreliable and expensive. This was because the community could not reach consensus on increasing the network capacity. Instead, they preferred Bitcoin become a settlement layer. Fortunately, a large portion of the Bitcoin community, including developers, investors, users, and businesses, still believed in the original vision of Bitcoin -- a low fee, peer to peer electronic cash system that could be used by all the people of the world.

On August 1st, , we took the logical step of increasing the maximum block size, and Bitcoin Cash was born. The network now supports up to 32MB blocks with ongoing research to allow massive future increases. 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 bitcoincashresearch. For those wishing to implement changes to the Bitcoin Cash protocol, it is recommended to seek early peer-review and engage collaboratively with other developers. Peer-to-Peer Electronic Cash. Fast Transact in seconds. Get confirmed in minutes. Reliable A network that runs without congestion. Low Fees Send money globally for pennies.

Simple Easy to use. One additional problem is that if multiple people are mining, using the same service string, they must not start with the same x or they may end up with the same proof, and anyone looking at it will not honor a duplicated copy of the same work as it could have been copied without work, the first to present it will be rewarded, and others will find their work rejected. This is what hashcash version 1 and bitcoin does.

In fact in bitcoin the service string is the coinbase and the coinbase includes the recipients reward address, as well as the transactions to validate in the block. Bitcoin actually does not include a random start point x, reusing the reward address as the randomization factor to avoid collisions for this random start point purpose, which saves bytes of space in the coinbase.

For privacy bitcoin expect the miner to use a different reward address on each successful block. A lot of hashcash design choices are motivated by simplicity. Of course because of luck the block time actually has quite high variance, but the average is still more accurately targeted by the introduction of fractional k. Bitcoin also defines a new notion of relative difficulty which is the work required so that at current network hashrate a block is expected to be found every 10 minutes.

In principle a miner should therefore for privacy use a different reward-address for each block and reset the counter to 0. Why Satoshi's early mined bitcoins were potentially linked, was because while he changed the reward-addresss, he forgot to reset the counter after each successful mine, which is a bitcoin mining privacy bug.

In fact with bitcoin the counter also should be obscured otherwise you would reveal your effort level, and if you have a lot of mining power that may imply who the coin belongs to. Bitcoin does this via the nonce and extra-nonce. Nonce starts at 0, but extra nonce is random. Together these form a randomized counter hiding the amount of effort that went into the proof, so no one can tell if it was a powerful but unlucky miner who worked hard, or a weak miner who was very lucky. Additionally with the introduction of mining pools, if the miner uses the same reward address for all users, which is what the current mining protocols do, then there is risk that users may redo work.

To avoid users redoing work, miners hand out defined work for the users to do. However this creates an unnecessary communication round trip and in early protocol versions perhaps was a factor in the decision to have the pool send the actual block to mine, which means the miners are not validating their own blocks, which delegates validation authority, though not work, to the pool operator, reducing the security of the bitcoin network. The more recent mining protocol version allows the user to add their own block definition, but still unnecessarily incur round trips for handing out work allocation.

Because the new pooled-mining protocol has a miner chosen extraNonce this acts as a random start factor so there is actually no need to talk to the pool for work allocation, a pool could have a static published address, and miners could just do work of whatever size they chose, and submit it to the pool as a UDP packet.

If privacy is required by the miner, it could use the public derivation method from BIP 32 to allow the node to tell the miner via an encrypted message with the mining work, which factor to multiply the static public key by. It is a misunderstanding to talk about the Scrypt proof-of-work. Scrypt is not intended as a proof-of-work function, but a stretched key-derivation function, and while it is by design expensive to compute with high iterations, it can not be used to make an efficiently publicly auditable proof-of-work, as verifying costs the same as creating.

Hashcash with the internal hash function of Scrypt may be denoted hashcash-Scrypt 1. Scrypt, by Colin Percival, is a key-derivation function for converting user chosen passphrases into keys. This does not use the key-stretching feature of Scrypt so mining is not actually using Scrypt directly, but only the inner Scrypt hash accessed by setting the iteration parameter to one iteration.

So Scrypt's key-stretching function is not being used at all to contribute to the hardness, unlike its normal use for key protection eg in deriving the encryption key from user passphrase to encrypt bitcoin wallets. The reason Scrypt's key-stretching can not be used for mining is because that simultaneously makes it more expensive to verify by the same factor.

The other major scrypt parameter denotes the amount of memory used usually kB. The kB Scrypt memory footprint makes it arguably less vulnerable to centralization of mining power arising from limited access to or ownership of ASIC equipment by users. This simplicity ensures that many people will do it and ASICs should become available. Conversely it is somewhat more difficult in comparison to make an hashcash-Scrypt 1 ASIC so perhaps it will prove in the mid-term actually worse for centralization, if a well funded commercial entity corners the market by having faster, but proprietary, not available on the market, hashcash-Scrypt 1 ASICs that render scrypt GPU mining unprofitable.

It is actually the output that partially matches, not the pre-image, so could perhaps more accurately called a pre-image with a partial output match, however partial pre-image effectively a short-hand for that. The miner varies counter c until this is true. The service string could be a web server domain name, a recipients email address, or in bitcoin a block of the bitcoin blockchain ledger. One additional problem is that if multiple people are mining, using the same service string, they must not start with the same x or they may end up with the same proof, and anyone looking at it will not honor a duplicated copy of the same work as it could have been copied without work, the first to present it will be rewarded, and others will find their work rejected.
