  区块链作为一种新型的技术组合,综合了P2P网络、共识算法、非对称加密、智能合约等新型技术,是一种在对等网络(也称分布式网络、点对点网络)环境下,通过透明和可信的规则,构建可追溯的块链式数据结构,具有分布式对等、链式数据块、防伪造和防篡改、可追溯、透明可信和高可靠性的典型特征


  数据作为新型生产要素,能为实体经济带来放大、叠加和倍增作用,是做强做优做大数字经济的关键。


  Establishing a reliable data circulation system to enhance the availability,credibility,circulation,and traceability of data is an important way to activate the potential of data elements and empower the real economy.区块链技术具有去中心化、共识机制、不可篡改、可以追溯、规则透明等特点。

  *Alternatively,{ERC165Storage}provides an easier to use but more expensive implementation.
