Back to: Blockchain 101 by EOS Union- 什么是区块链？

1. 区块链的基本组成中包含交易、区块和链三部分，若干交易信息被打包形成区块，区块间按发生顺序串联、延长成区块链；
2. 区块链是一个去中心化的数据库（系统）；
3. 区块链采用共识机制来对新增数据达成共识；
4. 区块链采用密码学的方法来保证已有数据不可能被篡改。

1. The basic composition of the blockchain consists of three parts: transaction, block and chain. Several transaction information is packaged into blocks, and the blocks are connected in series in the order of occurrence and extended into blockchains.
2. The blockchain is a decentralized database (system);
3. The blockchain uses a consensus system to reach consensus on new data;
4. The blockchain uses cryptographic methods to ensure that existing data cannot be tampered with.
