Embodiment Construction

[0036] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:

[0037] An energy data upload and consensus system based on on-chain and off-chain collaboration, such as figure 1 As shown, it includes: a plurality of user units, block chain side chains and block chain main chains; the plurality of user units are respectively connected through corresponding block chain side chains and block chain main chains; the user unit It is used to collect and upload energy data, and upload the generated signature to the blockchain side chain; the blockchain side chain is used to receive and store the signatures of each user unit, and send the homomorphic signature calculated after aggregation To the main chain of the block chain; the main chain of the block chain is used to verify the homomorphic signature information transmitted by the side chain and make the final record.

[0038] In this embodiment, the subscriber units...

Abstract

The invention relates to an on-chain and off-chain collaboration-based energy data uploading and consensus system and method. The system comprises a plurality of user units, a block chain side chain and a block chain main chain, the plurality of user units are respectively connected with the block chain main chain through the corresponding block chain side chains; the user unit is used for collecting and uploading energy data and uploading a generated signature to the block chain side chain; the block chain side chain is used for receiving and storing the signature of each user unit, and sending the homomorphic signature which is calculated after aggregation to the block chain main chain; and the block chain main chain is used for verifying the homomorphic signature information transmitted by the side chain and making a final record. According to the invention, the problems of block chain storage capability and data credibility in an energy data uploading process can be solved.

Description

technical field [0001] The invention belongs to the field of blockchain technology and energy data technology, and relates to an energy data upload and consensus system and method, in particular to an energy data upload and consensus system and method based on on-chain and off-chain collaboration. Background technique [0002] Blockchain technology is referred to as BT (Blockchaintechnology), also known as distributed ledger technology. Blocks, as the basic unit of the blockchain, are connected to each other in chronological order. In the blockchain, there are many distributed nodes, each node can store transaction information, and the digital ledger is arranged on each node. The information stored by the node is shared with other nodes through the peer-to-peer (p2p) network, and then the accuracy is verified through the consensus mechanism, and then stored in the node's ledger. After encryption, the information stored in the ledger on each node cannot be modified. Theref...
