A blockchain-based trading platform

Abstract

The invention discloses a blockchain-based transaction platform, including a basic capability layer, a blockchain layer, a business layer and an application layer, and the basic capability layer includes carbon emission monitoring, data transmission, attribute-based encryption infrastructure and a database The unit is used to provide basic support for various functional services of the trading platform; the blockchain layer includes an interface sublayer, an interconnection sublayer and a contract sublayer, which are used to build systems related to blockchain services; the business The layer includes security management, transaction management, traceability management and data management units, which are used to realize specific business processes; the application layer includes carbon resource holders, carbon indicator sellers, carbon indicator acquirers and government regulator units, which are Users in the trading platform provide corresponding applications. The present invention realizes non-tampering, privacy protection and traceability of carbon transaction data through data interaction between layers, and solves the problems of high management cost, difficult implementation and low transaction efficiency in the process of carbon transaction.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things, in particular to a blockchain-based trading platform. Background technique [0002] In recent years, the effects of the greenhouse effect and global warming have made people around the world aware of the negative consequences of excessive carbon emissions, and carbon emissions trading schemes have emerged as the times require. In the emission trading system, the government issues a certain number of carbon emission permits to enterprises according to their needs or through auctions, which is the so-called primary market. In the secondary market, companies with excessive or insufficient carbon emission demands can meet their respective demands through transactions, so it is necessary to establish a carbon trading platform to regulate this market behavior. [0003] At present, 8 carbon trading platforms have been built in the country. These trading platforms are all traditional cent...

AI Technical Summary

Problems solved by technology

[0004] (1) User privacy issues. Enterprises participating in carbon trading will expose their business privacy data during the transaction process. In traditional blockchain systems, transaction information can be queried at will on the chain, so the privacy of participants is difficult. be guaranteed;

[0005] (2) The problem of data traceability. Some blockchain systems encrypt user data symmetrically or based on public key infrastructure to protect user privacy. However, this makes it difficult to trace the source of responsibility in the event of data leakage;

[0006] (3) Consensus mechanism issues. Some blockchain systems adopt PoW or PoW-like consensus mechanisms. By issuing additional tokens for participants to increase transaction enthusiasm, this will lead to a significant extension of transaction confirmation time and increase the energy consumption of some nodes. Contrary to the purpose of the carbon trading platform
