The Bitcoin blockchain was launched on 3 Jan 2009 by its pseudonymous creator, Satoshi Nakamoto. Nakamoto had developed the idea of blockchain (sometimes called a decentralized ledger) as a solution to the problem of "double spending" in digital currencies. Previous systems had relied on a centralized authority (or "trusted third party") to make sure that transactions were legitimate, which fell short of Nakamoto's libertarian ideal of a truly unrestricted peer-to-peer currency. A blockchain is essentially a cryptographically secure public ledger containing every single transaction that has ever been made. When new transactions happen, they are verified by the network validators, using a cryptographic hashing algorithm, and are “waiting” in a queue to be added to a block. Once a block has been approved, it is added to the chain, containing the verified transactions, and transactions are confirmed.
