Bitcoin Is a Volatile Asset; How Is Its Price Set?
Bitcoin is a cryptocurrency , a digital asset designed to work as a medium of exchange that uses cryptography to control its creation and management, rather than relying on central authorities.
Prior to the release of bitcoin there were a number of digital cash technologies starting with the issuer based ecash protocols of David Chaum and Stefan Brands. The first proposals for distributed digital scarcity based cryptocurrencies were Wei Dai 's b-money  and Nick Szabo 's bit gold. In the bit gold proposal which proposed a collectible market based mechanism for inflation control, Nick Szabo also investigated some additional aspects including a Byzantine fault-tolerant agreement protocol based on quorum addresses to store and transfer the chained proof-of-work solutions, which was vulnerable to Sybil attacks, though.

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.

Bitcoin is the original cryptocurrency released in as open-source software. It is a digital currency predicated on cryptographically secure transactions, a proof-of-work consensus model, and a decentralized, P2P distributed ledger network.

The network is entirely P2P, and there are no intermediaries or centralized control. Since its inception, Bitcoin has fueled the growth of an entire industry of cryptocurrencies.
