Design and implementation of smart contracts for power networked command system

Abstract

The current power networked command system is usually centrally deployed, and there is a risk of data tampering during the command process. This article utilizes the technological advantages of blockchain tamper resistance and traceability to design smart contracts for the entire commanding process, achieving full process tracking of the commanding, orderly storage of instruction information, and effective verification of the operation process. This article first analyzes the security issues existing in the current networked command system and explains the necessity of instruction authentication and verification. Then, combined with the command process, the technical architecture and business logic of the smart contract were designed, including a scheduling instruction certificate contract, a content consistency verification contract, and a sequence verification contract. Finally, according to the scheduling instruction execution scheme of the smart contract, a typical networked ordering process is implemented. Tests have shown that the ordering contract has anti tampering and traceability characteristics, and its performance meets the system requirements.
