| The current university student innovation and entrepreneurship platform adopts a centralized working model,and there is a problem of centralized trust crisis.Malicious administrators can use their own rights to achieve the purpose of seeking public benefit.For example,malicious administrators take the user's entrepreneurial projects as their own or resell other users through transactions,causing losses to platform users.In order to solve this problem,this paper proposes a college student innovation and entrepreneurship information data service platform based on blockchain technology.The main work of the paper is as follows:First,it introduces the relevant concepts of blockchain technology,and analyzes in detail the technical advantages of blockchain technology in solving the difficulties in the development of college students' innovation and entrepreneurship platforms:(1)College students innovation and entrepreneurship data service platform based on blockchain technology A decentralized working model is adopted,which eliminates the need for administrators to maintain the platform and eliminates the problem of centralized trust crisis.(2)Blockchain technology can accelerate the transmission of entrepreneurial information.Once the smart contract is coded,it will be uploaded to the blockchain network,which will be received by all network verification nodes.Based on this feature,when a user obtains the consensus of most users,they can upload their own entrepreneurial information,and users across the entire network will be notified as soon as possible,speeding up the transmission of information.(3)Blockchain technology solves the problem of ownership of entrepreneurial information through timestamp and verification signatures.Each block contains a timestamp and a signatures.The timestamp when the new timestamp is formed.signatures is the signature of the transaction information by the user using his own private key when accounting.First,the location of the block can be queried on the blockchain through the time stamp,and then the hash on the block is verified using the user's public key.If the verification is passed,this user is the new owner of this venture.Based on this feature,it can be proved that who is the holder of this entrepreneurial information.Then,based on the business defects and technical difficulties of the existing college student entrepreneurial platform,the research uses blockchain technology to design optimization solutions,and proposes the overall design and system architecture of the college student entrepreneurial platform based on blockchain technology.The system architecture is divided into four levels: application interaction layer,business logic layer,blockchain layer and bottom-level services.Among them,the application interaction layer mainly implements Web applications that the system interacts with users,providing users with convenient front-end pages;the business logic layer mainly divides functions according to system requirements,provides interface services for the system application layer,and implements user-system interaction functions;The blockchain layer mainly includes smart contracts,PBFT consensus mechanism and core components of the blockchain;the bottom layer provides the required services to the system,including P2 P network,asymmetric encryption algorithm,distributed storage and other basic services.Finally,analyze the operating results of the platform.The analysis shows that the designed system is safe,reliable and decentralized,which technically overcomes the deficiencies of the existing entrepreneurial platform for college students. |
