Second-hand transaction and article borrowing and returning system based on alliance chain

Abstract

According to a second-hand transaction and article borrowing and returning system based on the alliance chain provided by the invention, the coupling between the front end and the rear end and betweenthe rear end and the alliance chain is reduced by performing on-chain permission authentication on front-end login users, and meanwhile, the burden of the alliance chain in the system is effectivelyreduced and the physical hardware requirements of the system are reduced through a four-layer architecture mode; users can be registered as alliance chain users more simply it is more easier for usersto register to become users of the alliance chain, the threshold is lower, and system managers can directly control the number of the users using the alliance chain in the system; therefore, the uploading and query of all records are automatically standardized, the right confirmation cost is reduced, and the transparency of article borrowing and returning credit records and the authenticity and credibility of transaction information of buyers and sellers are realized.

Description

technical field [0001] The present invention relates to the field of block chain technology, in particular to a second-hand transaction and item lending system based on alliance chain. Background technique [0002] For second-hand transactions, it is common for merchants and buyers to deceive each other in the current second-hand transaction software. In such cases, the investigation costs for managers are high and evidence collection is difficult. Most of the cases are ignored, which damages consumers and The seller’s basic interests, so every step of the user’s purchase operation is recorded on the blockchain, and the use of the blockchain’s own anti-counterfeiting, traceability and non-tampering characteristics can reduce the cost of investigation and make every investigation result authentic and credible . [0003] For the borrowing and returning of goods, the current domestic credit reporting system is only for large-amount credit registrations such as housing loans, t...

Problems solved by technology

[0004] However, the application of alliance blockchain technology to realize the information records of the above-mentioned second-hand transactions and items borrowed and returned still has problems such as heavy system burden and high demand for physical hardware. Whether it is an individual or an enterprise unit, the material cost and shared resources of establishing an independent alliance organization There is always a certain contradiction in the balance of information leakage; and the coupling between the alliance chain smart contract and software function development greatly reduces the application implementation scenarios and requirements; and the bigger problem is that when multiple users access the alliance chain, The efficiency of certificate configuration is low. Blockchain has the advantages of distributed, consensus mechanism, high security, strong survivability, decentralization, and trust establishment. It can effectively avoid single point of failure, improve certificate configuration efficiency, and solve multi-CA The problem of mutual trust; but the defects it brings are also obvious, first: the coupling between the blockchain and users is greatly increased; second: the threshold for users to use the blockchain is also extremely increased; third: the Greatly increase the computer resources of the blockchain network environment, even if many application scenarios do not need
