But these coins can be divided into smaller parts with the smallest divisible amount one hundred millionth of a Bitcoin.

Fast Company' s investigation brought up circumstantial evidence linking an encryption patent application filed by Neal King, Vladimir Oksman and Charles Bry on 15 August , and the bitcoin.

The patent application contained networking and encryption technologies similar to bitcoin's, and textual analysis revealed that the phrase " The two researchers based their suspicion on an analysis of the network of bitcoin transactions.

Nakamoto's involvement with bitcoin does not appear to extend past mid Other clues suggested that Nakamoto was British: A newspaper headline he had encoded in the genesis block came from the UK-published newspaper The Times , and both his forum posts and his comments in the bitcoin source code used British English spellings, such as "optimise" and "colour".

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.
