Research on Network Trading System Using Blockchain Technology

Blockchain technology is actually a distributed database technology. It adopts a series of security technologies such as P2P network technology, asymmetric encryption technology and smart contract technology to ensure the security and reliability of transactions. It has advantages of decentralization, anonymity and traceability. In view of the problems existing in the current centralized network transaction mode, this paper creatively proposes the design scheme of “network trading system based on blockchain technology”, and proposes a safe and feasible network transaction system model to ensure the transaction in network data transmission, data processing and other aspects of security. In-depth research and elaboration of some key technologies and principles in the network trading system. Comprehensive application of P2P network technology, asymmetric encryption technology, consensus mechanism, smart contract and other technologies to solve the security problem of network transaction systems. The specific implementation process is given for the transaction system from the aspects of demand analysis, transaction process, interface design, data model design and storage scalability design. Finally, it summarizes the application of blockchain technology in network transactions and points out the future research direction.
