blockchain英文介绍

A block chain, or blockchain, is a distributed database that maintains a continuously-growing list of data records hardened against tampering and revision. It consists of data structure blocks—which hold exclusively data in initial blockchain implementations, and both data and programs in some (for example, Ethereum) of the more recent implementations—with each block holding batches of individual transactions and the results of any blockchain executables. Each block contains a timestamp and information linking it to a previous block.

The block chain is seen as the main technical innovation of bitcoin, where it serves as the public ledger of all bitcoin transactions. Bitcoin is peer-to-peer, every user is allowed to connect to the network, send new transactions to it, verify transactions, and create new blocks, which is why it is called permissionless. This original design has been the inspiration for other cryptocurrencies and distributed databases.

Blockchain是一种分布式数据库技术，通过密码学和共识算法保证数据的不可篡改性和去中心化。它被广泛应用于数字货币、智能合约、供应链管理等领域，能够实现数据的透明性、安全性和高效性。它是未来数字经济发展的重要基础设施之一。
