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.

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.

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.
