A blockchain-based power trading system, consensus method, device, and storage medium.

Abstract

This invention provides a blockchain-based power trading system, consensus method, device, and storage medium, including a reputation module, a sharding module, an intra-shard consensus module, and a cross-shard consensus module. The sharding module divides nodes into multiple shards based on their reputation values ​​and geographical locations. The reputation module, composed of a reputation chain, calculates the reputation value of each node within a shard based on its operational data. The intra-shard consensus module verifies node transactions within a shard using an intra-shard consensus algorithm based on the node's transaction information and proposes cross-shard transactions for nodes within the same shard. The cross-shard consensus module verifies cross-shard transactions through a multi-level cross-shard consensus mechanism. This invention, by incorporating nodes into shards based on a reputation mechanism, ensures security within each shard. The multi-level cross-shard consensus mechanism verifies cross-shard transactions, guaranteeing secure and efficient transaction processing.
