Research And Application Of Consensus Mechanism In Transaction Alliance Chain Based On Reputation Model

The digital order trading platform is a new type of e-commerce platform that allows orders to be transferred and traded as digital assets,and has delayed delivery(futures)characteristics,which can reduce supply and demand side transactions and financial pressure.The platform utilizes the decentralized and tamper resistant characteristics of the alliance chain to provide a secure trading environment that meets the needs of users.Therefore,in the alliance chain environment where multiple roles,digital assets,and physical transactions coexist,how to achieve digital asset transactions,manage multi role users reasonably,and efficiently reach alliance chain consensus has become the key to whether the system can be efficient and fair.The default trust between users of the digital order trading platform cannot restrict user behavior.Node dishonesty,oligopoly and user inaction will have a negative impact on the fairness and stability of the platform’s trading environment.To address the issues of user dishonesty,monopoly,and inaction,this article proposes a reputation based alliance chain consensus mechanism,which personalized classifies and manages nodes based on user functions and assigns individual reputation to each user.This mechanism is used to quantitatively evaluate user behavior and reward and punish reputation based on user behavior.The main work of this article is as follows:(1)The user reputation model and dynamic discount calculation method are designed,and the user’s personal reputation,the historical transaction success rate and the historical block success rate are taken as the comprehensive standard to measure the user’s rights and interests,so that the user reputation evaluation standard is more comprehensive.(2)Based on the user reputation model,the alliance chain consensus mechanism is designed,and the user module,transaction module and reputation module are implemented according to the actual transaction demand,taking the alliance chain consensus cycle as the unit.(3)Combining alliance chain,user reputation,dynamic discount trading method and smart contract,demand analysis,system design and detailed design are carried out on the digital order trading platform,and a digital order trading platform system based on alliance chain is realized,which provides users with the coexistence of digital assets and commodities,the dynamic calculation of commodity discounts and the reliable service of delayed trading.And better solve the user trust,market monopoly and inaction,improve the quality of service and efficiency.This system is built on the underlying framework of the FISCO BCOS alliance chain,linking reputation rewards and punishments with user rights.It can motivate users to constantly manage their trading behavior and enhance reputation to gain more rights.Ultimately,it achieves an organic combination of alliance chain technology,multi role supply chain market,and digital asset trading,making the trading environment safer,more honest,and more fair.
