Bitcoin is a decentralized electronic cash system using peer-to-peer networking, digital signatures and cryptographic proof to enable irreversible payments between parties without relying on trust. Payments are made in bitcoins (generally quantified in BTC units - 100,000,000 of the "raw" bitcoin), a digital money issued and transferred by the Bitcoin network. Transactions were not broadcast by nodes to the network, which records them after validating them with a proof-of-work system.[3]
The Bitcoin network started on January 3, 2009 with the issue of the first bitcoins.[4] In exactly the same month the creator, Satoshi Nakamoto, released the initial Bitcoin client as open-source software.
Various possible assaults to its own use as a payment system and the bitcoin network, theoretical or actual, happen to be considered. The bitcoin protocol contains several characteristics that shield it against a few of those strikes, including unauthorized spending, twice spending, counterfeiting bitcoins, and tampering together with the block chain.[45] Other assaults, including larceny of private keys, demand due care by users.
