Nakamoto was responsible for creating the majority of the official bitcoin software and was active in making modifications and posting technical information on the bitcoin forum.

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.

They cut up printouts of their private keys into pieces and then distributed them in envelopes to safe deposit boxes around the country, so if one envelope were stolen the thief would not have the entire key.
With Gemini, they have created a high-tech version of this process to hold customer money. Gemini got a license from New York State regulators that allows them to hold Bitcoins for regulated banks and asset managers — something essentially no other virtual currency companies can do.

Gemini is now expanding from its old 5,square-foot offices to new, 35,square-foot facilities in Midtown Manhattan.
