Second-hand transaction and item lending system based on alliance chain

Abstract

The present invention proposes a second-hand transaction and item borrowing and returning system based on the alliance chain, which reduces the coupling between the front end and the back end and the coupling between the back end and the alliance chain by performing on-chain authority authentication on the front-end login users, and at the same time through the four-layer architecture Mode, effectively reducing the burden of the alliance chain in the system, reducing the physical hardware requirements of the system; making it easier for users to register as alliance chain users, with lower thresholds, and system managers can directly control the number of users using the alliance chain in the system; In turn, it automatically regulates the chaining and query of all records, reduces the cost of confirmation of rights, and realizes the transparency of credit records for borrowing and returning items and the authenticity and credibility of transaction information between buyers and sellers.

Description

technical field [0001] The invention relates to the technical field of blockchain, and in particular to a second-hand transaction and item loan and return system based on a consortium chain. Background technique [0002] For second-hand trading, the current second-hand trading software generally has the situation that merchants and buyers deceive each other. When such a situation occurs, the investigation cost of the administrator is high, and it is difficult to obtain evidence. The basic interests of the seller, so every step of the user's purchase operation is recorded on the blockchain, and the blockchain itself is used to reduce the cost of investigation and make every investigation result authentic and credible. . [0003] For the loan and return of goods, the current domestic credit reporting system is only for large-amount credit registration such as housing loans, taxes, and credit loans, but for low-value borrowing and credit behavior such as borrowing money from f...

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
