Abstract

A service can be an intangible commodity in which no physical goods are transferred from the seller to the buyer. However, traditional trading platforms have many limitations in trading services due to dishonest buyers and brokers. In this paper, we propose a service trading ecosystem based on blockchain, named STEB, which combines blockchain, smart contract, encryption, and digital authentication techniques for service trading. In addition, a dual-chain architecture, which contains two types of blockchains, namely TraChain and SerChain, and a hierarchical encryption scheme of the data on the chain, are proposed to ensure the integrity of transaction data and fine-grained privacy protection of users. Furthermore, we describe a new set of smart contracts to ensure safe transactions for the entire service trading. Security analysis and simulation results confirm that the proposed STEB can achieve more efficient contract execution and enhance service transaction privacy.

摘要

服务可以是一种无形的商品，在这种商品中，没有实物从卖方转移到买方。然而，由于不诚实的买家和经纪人的存在，传统的交易平台在服务交易方面存在许多限制。在本文中，我们提出了一种基于区块链的服务交易生态系统，名为 STEB，它结合了区块链、智能合约、加密和数字认证技术来进行服务交易。此外，还提出了一种双重链架构，其中包含两种类型的区块链，即 TraChain 和 SerChain，以及链上数据的分层加密方案，以确保交易数据的完整性和用户的细粒度隐私保护。此外，我们还描述了一组新的智能合约，以确保整个服务交易的安全。安全分析和模拟结果证实，所提出的 STEB 可以实现更高效的合约执行，并增强服务交易隐私。
