Blockchain-powered secure trading framework for power dispatch in metaverse

Power scheduling problem is a current research hotspot, and a meta-universe power trading operation system based on blockchain technology is proposed to address the problems of data silos, privacy leakage and low collaborative efficiency in traditional power scheduling system. By introducing homomorphic encryption, zero-knowledge proof and secure multi-party computing technology, it ensures the privacy protection of user data and realizes the safe aggregation and sharing of data. At the same time, Byzantine Fault Tolerance (PBFT) consensus mechanism is adopted to effectively resist the interference of potentially malicious nodes and safeguard the normal conduct of transactions and data security. In addition, by combining the Multi-Objective Particle Swarm Optimization (MOPSO) algorithm with smart contracts, the automation and decision-making optimization of power scheduling is realized, which significantly improves the operational efficiency of the scheduling system. The innovative data management scheme combining non-homogenized tokens (NFT) and interplanetary file system (IPFS) provides a secure and efficient data storage and transmission environment for the power trading market, which strongly protects the privacy and security of market data. This complete blockchain collaboration system has a broad development prospect and great application value for enhancing the security and operational efficiency of the power system in the context of meta-universe.
