Block by block: A blockchain-based peer-to-peer business transaction for international trade
针对第三方参与商业交易带来的信息泄露、成本高等问题，提出基于区块链和智能合约的信用证机制，并用BPMN 2.0建模展示其运作。
Heterogeneity and complicated processes, risk of information leakage, and higher costs are some of the challenges that stem from third-party involvement in business transactions. This study proposes a novel mechanism to address the shortcomings of third-party-dependent transactions in the context of international trade. Moreover, we provide business process modeling, deployed in a business transaction scenario, to furnish a deeper perspective on the working of the mechanism based on Business Process Model and Notation (BPMN) 2.0 standards and guidelines. By analyzing and identifying blockchain roles and capabilities, this study proposes a blockchain technology-based letter of credit (BTLC), which is a mechanism providing letters of credit (LCs) that incorporate the benefits of blockchain and smart contracts.
