Abstract: In recent years, as more services become available on the internet, selecting the best quality services from a group of similar web services and ensuring their authenticity remains a challenge. This paper proposes a blockchain-based service selection method that combines blockchain and service selection to provide a decentralised and trustworthy service selection platform. A smart contract is designed and deployed on the blockchain to help solve service selection problems and prevent information tampering. The moth-flame optimisation algorithm is improved by introducing the mutation and crossover of the differential evolution algorithm for service selection on the blockchain. The experimental results demonstrate that the proposed method effectively prevents service quality tampering and reduces service prices compared to traditional service selection methods and other metaheuristic algorithms.
