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.
Solitude is attained while making other transaction data public by not identifying owners of bitcoin addresses. Bitcoin users will not be identified by name, but trades could be linked to individuals and companies.[69] also, bitcoin exchanges, where people buy and sell bitcoins for fiat money, may be needed by law to gather personal advice.[70] To preserve fiscal seclusion, a distinct bitcoin address for every trade is recommended.[71] Transactions that spend coins from several input signals can reveal the input signals might have a common owner. Users concerned with privacy can use so-called mixing services which swap coins they possess for coins with different transaction histories.[72] It has been suggested that bitcoin payments shouldn't be considered more private than credit card payments.
