Research And Application Of Ant Colony Smart Contract Algorithm For Logistics Service Transaction Based On Blockchain

Modern service industries such as e-commerce,logistics,finance,government affairs,and tourism have developed rapidly.However,their service transaction contracts are still in a manual or human-computer interaction phase,and the operation process lacks automation and intelligentize.The contract information related to the service transaction contract,such as data,content,pricing,payment method,etc.,has its credit center,and there are credit and security storage issues such as opaque,unrecognizable,tamperable and repudiable contract information.With the development of artificial intelligence and blockchain technology,new ideas have been provided for problems in modern service transactions such as logistics.The use of blockchain to solve the problem of decentralization,nontampering,untrackability,tampering and repudiation of service transactions;using swarm intelligence to solve the automation and intelligentize of logistics service transactions.Therefore,we integrate blockchain and swarm intelligence technology to study the logistics service transaction contract algorithm,which has important scientific significance and application value.Firstly,the traditional logistics service transaction model and its workflow are analyzed and researched.According to the current logistics service transaction system environment and architecture,a traditional centralized model of logistics service transaction is constructed.Then,according to the characteristics of the blockchain technology,the basic ideas for solving the problems existing in the traditional logistics service transaction centralization model are given.Converging the structure of the logistics blockchain,as well as the information flow,negotiation,contracting,payment and other transaction processes in the logistics service transaction and the link relationship of the blockchain,and constructing a decentralized logistics service transaction swarm intelligence contract model to solve the logistics Service transaction centralization model data centralization problem.Then according to the advantages of ant colony algorithm,the problem of intelligent matching of logistics service transactions is solved,and an improved ant colony algorithm is proposed.According to the blockchain-based logistics service transaction swarm intelligence contract model and the improved ant colony algorithm,a blockchain-based logistics service transaction ant colony intelligent contract algorithm is proposed.Finally,in the experimental environment based on Ethereum,the algorithm is simulated by multi-node logistics service transaction.The experimental results show that the proposed algorithm can realize the creation,storage and execution of multi-node and multi-user logistics service intelligent contracts,and solve the current logistics service centralization,the lack of intelligence in transaction operations and the existence of credit problems.
