Study on the Power Data Assets and Trading System Design of Blockchain

The sensitive data such as electric power data suffer from the easily abuse in the traditional centralized data trading system. To solve this problem, the blockchain-based power data's capitalization and trading system were proposed in this study. Given the trust for blockchain technology, this work established a multi-party trusty network between multiple parties in the distributed ledger with cryptographic algorithms, and distributed multi-party consensus protocol. The system development with Hyperledger's consortium blockchain framework Fabric made the power data safe, transparent and immutable. The local development environment for testing included a operating system MAC OS 10.14.6, six-core CPU 3.0 GHz, RAM 16 GB. A single machine is configured with multiple block chain network nodes, an ordering node, and two organizations Org0 and Org1, each of which has two nodes Peer0 and Peer1, and adopts the Solo consensus mechanism. The experimental results show that the system run well in the integrated test, satisfied the design requirements, and had low maintenance costs and improved security. Compared with the traditional data trading system, the blockchain-based power data's capitalization and trading system demonstrated the comprehensive functionality and security advantages in the study.
