摘要
在传统票据市场中,以电子商业汇票系统为核心的集中管理模式导致信息不对称、人工操作失误、监督溯源效率低等问题频发,因此,票据交易的真实性、安全性存疑。针对以上问题,该文利用区块链技术去中心化、不可篡改、可溯源的特性,提出了一种基于区块链的票据交易可信管理方案。通过设计去中心化的数据结构和验证机制,实现了交易合同的去中心化可信存储,确保了交易背景的真实性;并采用去中心化的验证方式建立了票据交易真实性和完整性验证机制,实现了交易数据的可信验证;此外,通过结合区块链技术和可信执行环境,建立节点身份远程验证机制,实现了节点身份信息的去中心化真实性验证,确保了参与方身份真实性。最后,采用Hyperledger Fabric区块链平台对方案进行了仿真实现和测试,结果表明,该方案实现了票据交易合同和签发的可信管理。
The conventional bill market faces challenges like information asymmetry,human errors,and low supervision efficiency due to its centralized management model centered on the electronic commercial bill system.Consequently,doubts arise regarding the authenticity and security of bill transactions.In response,we propose a trustworthy management solution for bill transactions based on blockchain technology.Leveraging the decentralized,tamper-resistant,and traceable nature of blockchain,the scheme designs decentralized data structures and verification mechanisms,which enables decentralized and trustworthy storage of transaction contracts,ensuring the authenticity of transaction backgrounds.Furthermore,a decentralized verification approach establishes a mechanism to verify the authenticity and integrity of bill transactions,facilitating trustworthy validation of transaction data.Additionally,by integrating blockchain technology with trusted execution environments,a remote verification mechanism for node identity is established,ensuring decentralized authentication of participant identities.Simulation implementation and testing of the proposed scheme using the Hyperledger Fabric blockchain platform validate its efficacy in achieving trustworthy management of bill transaction contracts and issuance.
