Carbon data storage and transaction system based on block chain

Abstract

The invention provides a carbon data storage and transaction system based on a block chain, and relates to the field of carbon emission permit transaction. The system comprises: carbon transaction nodes, wherein each carbon emission control enterprise and a voluntary carbon emission reduction enterprise being a carbon transaction node to realize the transaction of carbon emission permissions; and a carbon checking nodes, wherein other authoritative units authorized by the generation and transformation committee or the government in each area are carbon checking nodes and are responsible for issuing carbon emission permit quotas, checking carbon residual quotas of emission control enterprises and checking total carbon residual quotas. According to the system, the transparency of carbon transaction information can be enhanced, the authenticity and reliability of transaction prices are ensured, and all authorized users have the right to query carbon transaction and carbon emission historical information; meanwhile, the management and supervision cost of transaction information can be reduced, the transaction efficiency is improved, and the activeness of a carbon emission transaction market is enhanced; and only the hash value generated by the transaction information of the buyer and the seller of the transaction node is stored in the block, so that the data capacity of each block in the block chain is reduced, and the transaction speed is improved.

Description

technical field [0001] The invention relates to the field of carbon emission right trading, in particular to a carbon data storage and trading system based on blockchain. Background technique [0002] Carbon emission rights refer to the total amount of greenhouse gases emitted during energy consumption, including available carbon emission rights and required carbon emission rights. According to the division of trading objects, the international carbon market can be divided into two categories: allowance trading market and project trading market. Emission reduction vouchers obtained by implementing projects to reduce greenhouse gases; according to the division of organization, the carbon trading market can be divided into on-exchange transactions and off-exchange transactions. Carbon trading is mainly conducted in the off-exchange market at first. The platform is gradually established; according to the division of legal basis, the carbon trading market can be divided into ma...

AI Technical Summary

Problems solved by technology

[0004] Under the traditional model of carbon emissions trading, due to the asymmetric trading information and opaque trading process, black-box operations and data falsification often occur in carbon trading; at the same time, the trading process is cumbersome, and the cost of supervision and supervision is too high. In the absence of uniformity, the authenticity and reliability of transaction price information cannot be guaranteed. At the same time, due to the excessive intervention of regulatory agencies and the existence of matching links by intermediary agencies, transaction efficiency is low, resulting in less and less active carbon market transactions.
