#特朗普就职百日 Bitcoin has freed itself from the constraints of third-party institutions through a public distributed ledger, referred to as the "blockchain" by Satoshi Nakamoto. Users are happy to contribute their mining machine computing power, running a special software to become a "miner," which forms a network to jointly maintain the "blockchain." In this process, they also generate new currency. Transactions also spread across this network, with computers running this software competing to solve irreversible cryptographic puzzles, which include multiple transaction data.
