History Of Bitcoin!

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.[1] The presumed pseudonymous Satoshi Nakamoto integrated many existing ideas from the cypherpunk community when creating bitcoin.
Pre-history Edit

Prior to the release of bitcoin there were a number of digital cash technologies starting with the issuer based ecash protocols of David Chaum [2] and Stefan Brands. Adam Back developed hashcash, a proof-of-work scheme for spam control. The first proposals for distributed digital scarcity based cryptocurrencies were Wei Dai's b-money[3] and Nick Szabo's bit gold.[4][5] Hal Finney developed reusable proof of work (RPOW) using hashcash as its proof of work algorithm.[6]

In the bit gold proposal which proposed a collectible market based mechanism for inflation control, Nick Szabo also investigated some additional enabling aspects including a Byzantine fault-tolerant asset registry to store and transfer the chained proof-of-work solutions.[5]

There has been much speculation as to the identity of Satoshi Nakamoto with suspects including Wei Dai, Hal Finney and accompanying denials.[7][8] The possibility that Satoshi Nakamoto was a computer collective in the European financial sector has also been discussed.[9]
On 18 August 2008, the domain name bitcoin.org was registered.[10] In November that year, a link to a paper authored by Satoshi Nakamoto titled Bitcoin: A Peer-to-Peer Electronic Cash System[11] was posted to a cryptography mailing list.[10] This paper detailed methods of using a peer-to-peer network to generate what was described as "a system for electronic transactions without relying on trust".[12][13][14] In January 2009, the bitcoin network came into existence with the release of the first open source bitcoin client and the issuance of the first bitcoins,[12][15][16][17] with Satoshi Nakamoto mining the first block of bitcoins ever (known as the genesis block), which had a reward of 50 bitcoins.
