Design And Implementation Of Leasing Platform For Major Scientific Research Devices Based On Blockchain

With the continuous expansion of the leasing industry market,there are new changes in the types and forms of leasing items.However,in the traditional centralized device leasing platform,the evaluation,description and data generated in the leasing process are all collected by a proprietary non transparent internal database,which may lead to problems such as asymmetric credit information,evidence collection of leasing disputes,difficulty in proof,and opaque credit transactions.As a distributed network architecture,blockchain uses chain block structure to verify and store data,uses distributed node consensus mechanism to package transactions and generate blocks,uses cryptography to ensure the security of access and data transmission,and uses smart contracts to write applications and exchange data,which can effectively solve the problems of appeal.Therefore,this thesis combines the blockchain to innovate the leasing form of major scientific research instruments,and proposes the design and implementation of the leasing platform of major scientific research device based on the blockchain.Firstly,this thesis introduces the background and significance of the research,and summarizes the research content.Then from the traditional device leasing platform,blockchain,Hyperledger Fabric project three aspects to introduce the technology used,and analyze their technical characteristics.Then it analyzes the requirements of the major scientific research device leasing platform based on the blockchain,and designs the hierarchical structure of the platform,mainly including the data transmission layer,the ledger layer,the service layer and the application layer.After that,according to the design scheme,the specific implementation of each level is carried out.Finally,the functional integrity of the platform,the effectiveness of the incentive strategy,the protection of private data,and the performance of the platform were tested,proving that the platform can make sure the data generated by the device leasing process to be monitorable,traceable and immutable in a decentralized way.
