A fork referring to a blockchain is defined variously as a blockchain split into two paths forward, or as a change of protocol rules.
Accidental 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.
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. Two significant forks took place in August. One, Bitcoin Cash , is a hard fork off the main chain in opposition to the other, which is a soft fork to implement Segregated Witness.

In summary, FinCEN's decision would require bitcoin exchanges where bitcoins are traded for traditional currencies to disclose large transactions and suspicious activity, comply with money laundering regulations, and collect information about their customers as traditional financial institutions are required to do.
Basic money-services business rules apply here.

There are also faucets that dispense alternative cryptocurrencies. The first bitcoin faucet was called "The Bitcoin Faucet" and was developed by Gavin Andresen in Faucets usually give fractions of a bitcoin, but the amount will typically fluctuate according to the value of bitcoin. Some faucets also have random larger rewards. To reduce mining fees , faucets normally save up these small individual payments in their own ledgers , which then add up to make a larger payment that is sent to a user's bitcoin address.
Because bitcoin transactions are irreversible and there are many faucets, they have become targets for hackers interested in stealing bitcoins. Advertisements are the main income source of bitcoin faucets. Faucets try to get traffic from users by offering free bitcoin as an incentive.

In August , the German Finance Ministry characterized bitcoin as a unit of account ,   usable in multilateral clearing circles and subject to capital gains tax if held less than one year.
