Abstract: Aiming at the problems of low data reliability, differentiated sharing and data right confirmation in traditional energy data supervision, this paper proposes a trusted supervision model of energy data based on alliance chain. This scheme relies on the data resource directory to establish a directory blockchain, store directory data on the chain, and store actual energy data off the chain, realizing the prechain supervision of data. For the actual data sharing stage, the access process records are uploaded to the chain, and an index structure is added to facilitate data query and realize the onchain supervision of data. The regulatory authority can verify the authenticity of offchain data by combining the chain of custody information, thus providing ideas for the supervision of energy data.

Key words: energy data, blockchain, onchain and offchain mapping, data supervision, data security, data sharing
