Transaction platform based on block chain

Abstract

The invention discloses a transaction platform based on a block chain. The transaction platform comprises a basic capability layer, a block chain layer, a service layer and an application layer, and is characterized in that the basic capability layer comprises a carbon emission monitoring unit, a data transmission unit, an attribute-based encryption infrastructure unit and a database unit, and is used for providing basic support for various functional services of the transaction platform; the block chain layer comprises an interface sub-layer, an interconnection sub-layer and a contract sub-layer, and is used for constructing a system related to block chain services; the service layer comprises a security management unit, a transaction management unit, a traceability management unit and a data management unit, and is used for realizing a specific service process; and the application layer comprises a carbon resource holder unit, a carbon index seller unit, a carbon index purchaser unit and a government supervisor unit, and provides corresponding applications for users in the transaction platform. According to the invention, through the data interaction among the layers, the tampering prevention, privacy protection and traceability tracking of the carbon transaction data are realized, and the problems of high management cost, high implementation difficulty and low transaction efficiency in the carbon transaction process are solved.

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
