互联网上的贸易,几乎都需要借助可信赖的第三方信用机构来处理电子支付信息。这类系统内生性地受制于“基于信用的模式”。
区块链技术是构建比特币区块链网络与交易信息加密传输的基础技术。其中基于密码学原理的特性,使得任何达成一致协议的双方直接支付,从而不需要第三方机构的参与。
什么是区块链?
区块链(Blockchain)技术自身仍然在发展中,目前还缺乏统一的规范和标准。Wikipedia 给出的定义为:
A blockchain —originally, block chain —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 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.
Wikipedia 给出的定义简单说来:区块链(原始区块链)是一个分布式数据库,它维护着一个不断增长的数据记录清单,加强了算法的篡改与修改。
