Abstract: To solve the lack of credit relationship among suppliers, producers, users and other multi-participants in logistics service transactions, improve the efficiency of contract formulation, avoid interfering with the normal execution of contracts and the repudiation, tampering and non-traceability of traditional contract. Logistics service transaction blockchain and ant colony smart contract algorithm is proposed. Firstly, it analyzes the problems existing in the traditional logistics service transaction model, proposes a new conceptual model of logistics service transaction contract, and utilizes the characteristics and advantages of blockchain and smart contract technology, as well as the information release, negotiation, bargaining, contracting in the logistics service transaction, and other trading links and blockchain links, and it also constructs a decentralized smart contract blockchain model for logistics service transaction. Then, based on the model, and according to the workflow of logistics service transaction contract, logistics service transaction blockchain and ant colony smart contract algorithm is designed. Finally, experiments are carried out on the multi-node logistics service transaction simulation platform. The experimental results show that the algorithm realizes the creation, storage and automatic execution of multi-logistics user service transaction smart contracts based on blockchain. The whole process is transparent, traceable, consensus and tamper-resistant. Therefore, The algorithm is an effective method to solve the problem of logistics service transaction based on blockchain.
