摘要：

[背景]国家电网在电力数据管理应用方面存在数据孤岛和价值孤岛的综合问题。[目的]可以借助区块链技术设计一种电力数据资产交易平台,使得电力数据可以跨部门、跨机构有偿共享。[方法]本文基于以太坊区块链技术,提出了基于智能合约的身份管理随机验证模型,采用了更适合于联盟链的POA共识机制作为链上节点的数据一致性方案,提出了基于区块链监听账户的周期性同步机制,使用了基于B+树的数据访问权追踪机制。[结果]基于以上方法,开发了基于联盟链的电力数据资产交易平台,实现了多验证节点参与的身份认证管理,避免了单点信任依赖造成的共谋作恶问题,兼顾了电力数据交易场景下共识过程的高效率与高安全性,解决了区块链在大量读操作场景下的效率低下问题,说明了访问权溯源追踪效率的综合性能优势。

Abstract:

[Background] In the application of power data management, the STATE GRID faces the problem of “data island” and “value island”. [Objective] It is possible to design and implement a trading platform for power data assets based on blockchain to share power data between different authorities. [Methods] Based on the Ethereum blockchain, we propose a random verification model of identity management based on smart contracts, adopt a POA consensus mechanism which is more suitable for consortium blockchain to keep data consistency among nodes on the chain, implement a periodic synchronization mechanism based on the blockchain monitoring account, and use B+ tree to make data access permission tracking mechanism. [Results] We develop a platform that integrates power data publication, purchase of access rights, and transfer of access rights based on consortium blockchain, achieve identity verification management involving multiple verification nodes, avoid wicked nodes’ bad behavior because of single node’s trust, guarantee the high efficiency and high safety, solve the problem of low reading efficiency of blockchain in some scenes, and demonstrate the advantages in tracking power data access rights.
