基于区块链的家政服务交易群智合约算法研究

BLOCKCHAIN-BASED HOUSEKEEPING SERVICE TRANSACTIONGROUP SMART CONTRACT ALGORITHM

为解决家政服务交易存在第三方平台上信息的不透明性、可篡改性,且在服务交易过程中缺少智能化,导致了家庭用户、家政服务提供者和家政服务交易平台等多方参与者之间存在信任问题,提出基于区块链的家政服务交易群智合约算法。根据家政服务的业务流程和交易特征,结合区块链的技术,并提出家政服务交易的区块链基本概念,构建去中心化的家政服务交易智能合约区块链模型。运用粒子群算法的群智特点,建立一种区块链的家政服务交易群智合约算法。通过实例和实验验证,该算法实现了去中心化和智能化,整个交易过程中信息公开透明、不可篡改。因此,该算法是解决家政服务交易信任问题的一种有效方法。

To solve the opacity and tamperability of information on the third-party platform for housekeeping service transactions,as well as the lack of intelligence in the service transaction process,which has led to the existence of the problem of trust among multi-party participants such as home users,housekeeping service providers and housekeeping service trading platforms,a smart contract algorithm based on blockchain for housekeeping service transactions is proposed.Based on the business process and transaction characteristics of housekeeping services,combined with the technology of blockchain,the basic concept of housekeeping service transaction blockchain was proposed.A decentralized housekeeping service transaction smart contract blockchain model was constructed.By using the swarm intelligence feature of PSO,a smart contract algorithm based on blockchain for housekeeping service transactions was established.The examples and experimental verification show that the algorithm is decentralized and intelligent,and the information is open and transparent and cannot be tampered with during the entire transaction process.Therefore,this algorithm is an effective method to solve the trust problem of housekeeping service transactions.
