Problems solved by technology

However, since all information on the blockchain is publicly visible, the issue of privacy protection on it has always been an urgent problem to be solved
However, the method described in this patent cannot guarantee the credibility of the chain after data collection, and the specific energy data sharing scheme is not disclosed
In addition, this patent document does not use the homomorphic commitment to ensure the credible process, the privacy protection is weak, and it cannot ensure the credibility of the statistical data decryption results

Abstract

The invention relates to an energy data credible sharing system and method based on a block chain. The system comprises a plurality of electricity utilization ends, the block chain, an intelligent contract on the block chain, a central mechanism and a plurality of statistical result query parties. The plurality of power utilization terminals are respectively connected with the block chain and the smart contract on the block chain, the output ends of the block chain and the smart contract on the block chain are connected with the central mechanism, the output end of the central mechanism is respectively connected with the statistical result query party, the statistical result query party makes a query result request to the central mechanism, and the central mechanism decrypts and shows the query result. According to the invention, the privacy protection problem in energy data sharing management can be solved.

Description

technical field [0001] The invention belongs to the technical field of blockchain and energy data, and relates to an energy data trusted sharing system and method, in particular to a blockchain-based trusted energy data sharing system and method. Background technique [0002] Blockchain is a decentralized digital transaction ledger. Users can conduct peer-to-peer transactions without the need for a third party. Transaction data is stored in blocks through encryption technology and grows continuously in a chain structure, and is long-term reserve. Due to the unique chain structure and the consensus mechanism of point-to-point transactions, the blockchain is tamper-proof, and information can be safely stored, transmitted and processed in the blockchain. However, since all information on the blockchain is publicly visible, the issue of privacy protection on it has always been an urgent problem to be solved. [0003] At present, the data privacy protection based on the blockch...
