Abstract

The invention discloses a green electricity source tracing method and system based on an R-PBFT consensus algorithm and a timestamp. The method comprises the following steps: acquiring green electricity whole process data; generating a data abstract or a data identifier from the obtained green electricity full-process data through hash, storing the data abstract or the data identifier in a data block in a transaction mode, and processing the data abstract or the data identifier through a timestamp; after consistency confirmation is completed through a consensus algorithm, a new block is generated, and green electricity full-process data is stored in a block chain; and accessing the green electricity full-process data in the block chain through the intelligent contract, performing cross comparison, and judging whether the electricity consumption of the electricity consumption unit is all green electricity. According to the method, the block chain technology is combined, the key information of the whole process of'sending-transmission-distribution-transaction-use 'of the green electricity is chained, and the real and credible key information of the whole process of the green electricity is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of block chain application, and specifically relates to a method and system for traceability of green electricity based on R-PBFT consensus algorithm and time stamp. Background technique [0002] Blockchain is a distributed ledger of transactions. All complete client nodes existing in the system have a copy of the same ledger. All confirmed transactions in the blockchain system are stored in the ledger. These transactions are usually stored in blocks in the form of Merkle trees. Adjacent blocks are connected end to end to form a chain. This long chain of blocks is called a blockchain. . Blockchain is not a new technology, but a combination of various new technologies such as point-to-point transmission protocols, modern cryptography, consensus algorithms, smart contracts, etc. It has several characteristics: first, decentralization, blockchain technology Implementation and application do not depend on an...
