Bitcoin is a decentralized electronic cash system using peer to peer networking, digital signatures and cryptographic evidence without relying on trust to empower irreversible payments. Payments are created in bitcoins (normally quantified in BTC units - 100,000,000 of the "raw" bitcoin), a digital money issued and transferred by the Bitcoin network. Trades were not broadcast by nodes to the network, which records them after validating them using a proof-of-work system.[3]
The Bitcoin network started on January 3, 2009 using the matter of the very first bitcoins.[4] In exactly the same month the creator, Satoshi Nakamoto, released the initial Bitcoin client as open-source software.
Seclusion is achieved by not identifying owners of bitcoin addresses. Bitcoin users aren't identified by name, but transactions can be linked to individuals and businesses.[69] also, bitcoin exchanges, where people purchase and sell bitcoins for fiat money, may be needed by law to collect private information.[70] To maintain fiscal seclusion, a distinct bitcoin address for each transaction is recommended.[71] Trades that spend coins from multiple inputs can reveal the inputs may have a common owner. Users concerned about solitude can use so called mixing services that swap coins they own for coins with different transaction histories.[72] It has been proposed that bitcoin payments shouldn't be considered more private than credit card payments.
