Block chain-based power data cross-domain supervision method and system, and storage medium

The invention relates to a power data cross-domain supervision method and system based on a block chain and a storage medium, and the method comprises the following steps: a monitoring node module scans a block to capture a cross-chain event and traverses the generation of a new block; the block chain network adds a cross-domain event identifier to the event based on the captured cross-chain event; a communication node of the block chain network finds a corresponding event according to the cross-domain event identifier, and uploads the event to a center chain for consensus contract audit verification; and the center chain sends data consensus information to the target chain according to an audit result of the consensus contract, so that behaviors of the event are synchronously stored on the target chain, the source chain and the target chain reach a consensus, and cross-chain tracing and exception discovery functions are provided for the target chain. According to the method, the center chain is established b
