区块链大型巡回播放第175期“区块链是什么”

区块链可以解决互联网的痛点，价值交换的唯一性、交换双方相互信任等。区块链致力于成为一种工具，它具有自身可审计特性，参与者之间产生信任。区块链按照时间顺序排列，当前区块包含了上一个区块的哈希，想要作恶，重新交易需要重新计算区块的所有区块，计算难度很大，所以它称得上是可审计的工具。

区块链又称为一种去中心化的协议，区块链上的所有数据不可修改，所以它称为信任制造者。区块链为了方便理解，我们可以看成是一个很大的账本，中间加入的是公开的数据库，主要特点是点对点记账、通过数据传输达成共识。这个数据库内部含有过去的所有交易记录，有了区块链所有人类文明都将传承下来，最关键的是这些信息通过分布式存储，分布式储存的优势在于节点很多，相对于传统的单个服务器，节点越多越安全，数据遭到破坏的难度越大，恢复起来越方便。

Blockchain can solve the pain point of the Internet, the uniqueness of value exchange, the exchange of mutual trust between the two sides. Blockchain is committed to being a tool that has its own auditable nature and generates trust among participants. The blockchain is arranged chronologically, and the current block contains the Hasche of the previous block. To do evil, a new transaction would require recalculating all the blocks in the block, which is very difficult to do, so it can be called an auditable tool. Blockchain is also called a decentralized protocol.

All data on the blockchain can not be modified, so it is called a trust maker. For ease of understanding, the blockchain can be viewed as a large ledger with a public database in the middle, featuring peer-to-peer bookkeeping and consensus-building through data transmission. This database contains all the past transactions, with the blockchain all human civilization will be passed down, the key is that this information through distributed storage, distributed storage advantage is many nodes, compared with the traditional single server, the more nodes, the more secure, the more difficult the data is destroyed, and the more convenient it is to recover.
