区块链是分布式数据存储、点对点传输、共识机制、加密算法等计算机技术的新型应用模式。所谓共识机制是区块链系统中实现不同节点之间建立信任、获取权益的数学算法
BlockChain is a new application mode of distributed computing technology, such as distributed data storage, peer to peer transmission, consensus mechanism, encryption algorithm and so on. The so-called consensus mechanism is a mathematical algorithm for establishing trust and obtaining rights between different nodes in block chain system.
区块链（Blockchain）是比特币的一个重要概念，它本质上是一个去中心化的数据库，同时作为比特币的底层技术。区块链是一串使用密码学方法相关联产生的数据块，每一个数据块中包含了一次比特币网络交易的信息，用于验证其信息的有效性（防伪）和生成下一个区块
BlockChain (QuKuaiLian) is an important concept of bitcoin. In essence, it is a decentralized database and the underlying technology of bitcoin. Block chains are a series of data blocks associated with cryptographic methods, each of which contains information of a bitcoin network transaction to verify the validity of its information (anti-counterfeit) and generate the next block.
