The real identity of Satoshi Nakamoto still remains a matter of dispute. A fork referring to a blockchain is what happens when a blockchain splits into two paths forward. Forks on the bitcoin network regularly occur as part of the mining process.
They happen when two miners find a block at a similar point in time. As a result, the network briefly forks. This fork is subsequently resolved by the software which automatically chooses the longest chain, thereby orphaning the extra blocks added to the shorter chain that were dropped by the longer chain. A blockchain can also fork when developers change rules in the software used to determine which transactions are valid. On 12 March , a bitcoin miner running version 0.
This created a split or "fork" in the blockchain since computers with the recent version of the software accepted the invalid block and continued to build on the diverging chain, whereas older versions of the software rejected it and continued extending the blockchain without the offending block. This split resulted in two separate transaction logs being formed without clear consensus, which allowed for the same funds to be spent differently on each chain.
In response, the Mt. Gox exchange temporarily halted bitcoin deposits. Miners resolved the split by downgrading to version 0. User funds largely remained unaffected and were available when network consensus was restored.

Bitcoin power brokers have been squabbling over the rules that should guide the cryptocurrency's blockchain network. On one side are the so-called core developers. They are in favor of smaller bitcoin blocks, which they say are less vulnerable to hacking. On the other side are the miners, who want to increase the size of blocks to make the network faster and more scalable. Until just before the decision, the solution known as Segwit2x, which would double the size of bitcoin blocks to 2 megabytes, seemed to have universal support.
Then bitcoin cash came along. The solution is a fork of the bitcoin system. The new software has all the history of the old platform; however, bitcoin cash blocks have a capacity 8 megabytes.
