bitcoin transaction
Finney is commonly suspected to have invented Bitcoin. Beyond the fact that coders are often their own first users and business-founders their own first customers, Finney certainly had the chops to design something like Bitcoin, which combined several pre-existing cryptographic and computational ideas in a novel way. Bitcoin makes use of public-key cryptography to ensure the integrity of transactions created on the network. In order to transfer bitcoin, each participant has pairs of public keys and private keys that control pieces of bitcoin they own. A public key is a series of letters and numbers that a user must share in order to receive funds. In contrast, a private key must be kept secret as it authorizes the spending of any funds received by the associated public key. Nakamoto, S. Bitcoin: A peer-to-peer electronic cash system.
