Block chain-based transaction method, transaction system and computer storage medium

Abstract

The invention relates to a block chain-based transaction method, a transaction system and a computer storage medium, which not only make full use of the significant characteristics of decentralization, non-tampering, anonymity and the like of a block chain technology to promote two transaction parties to form an overlay network and ensure the legal rights and interests and security performance of the two transaction parties, but also can improve the transaction efficiency based on a market benefit maximization principle. Compared with a traditional auction mechanism or a distributed optimization mechanism, the method has the advantages that a market settlement problem is expressed as an optimization problem, so that two parties of the transaction can flexibly and autonomously bargaining and determining the transaction number, complete transaction is completed on the basis of economic benefit maximization, the benefits of participants of the market settlement are maximized, and the market settlement efficiency is improved. And the transaction efficiency is ensured. Particularly, on the basis of a projection subgradient method, a total optimization problem is converted into a local sub-optimization problem, a convergence result is obtained through multiple iterations, legal rights and interests of two transaction parties can be fully guaranteed, calculation accuracy is high, efficiency is high, and the method is an efficient and high-quality optimization algorithm.

Description

technical field [0001] The present invention relates to the technical field of blockchain, in particular to a distributed transaction method. Background technique [0002] Traditional large-scale exchanges take place in centralized exchanges. Since the introduction of blockchain technology, distributed peer-to-peer (P2P) exchanges have become possible due to its open ledger and tamper-proof features. Distributed trading platform, also known as decentralized exchange, decentralized trading platform. The distributed trading platform provides a new credit mechanism and value exchange mode based on the digital information exchange method created by the blockchain that does not rely on third-party trust. [0003] As a new way of energy management in smart grid, P2P energy trading has promoted the active integration of a large number of small producers and consumers into the market, while effectively improving the utilization rate of electric energy. Therefore, in recent years, ...

[0004] However, due to the particularity of electricity transactions, it is generally purchased and sold by the manager uniformly. If the purchase price is lowered and sold at a higher price, it will inevitably cause market chaos, fail to protect the legitimate rights and interests of producers and consumers, and fail to maximize economic benefits. , which is not conducive to the healthy development of the market; or through the auction mechanism, selling or buying electricity, the interests of both parties cannot be maximized; and the general distributed optimization mechanism may be too coupled, and then introduce too many iterative negotiations, increasing transaction time
