What is blockchain

A blockchain, originally block chain, is a continuously growing list of records, called blocks, which are linked and secured using cryptography.

区块链(英语:blockchain 或 block chain)是用分布式数据库识别、传播和记载信息的智能化对等网络, 也称为价值互联网。

一句话:分布式账本

区块链通过去中心化,解决了信任问题,但是带来了性能问题。

对于一致性(共识),由于存在拜占庭问题,区块链并不能使用传统分布式系统常用的 Paxos 或 Raft 算法,而是使用 PoW(Proof-of-Work 工作量证明)、PoS(Proof-of-Stake 权益证明)或 DPOS(Delegated Proof-of-Stake-of权益证明)等共识算法。
