Traceability systems have changed the way food safety is managed and data is stored. Blockchain tracking services now provide customers with an infrastructure that allows them to easily access data online. However, there are limitations to these new capabilities, such as a lack of transparency and the existence of privacy and security challenges. Additionally, as the need for more agile, private, and traceability secure data solutions continues to grow exponentially, rethinking the current structure of blockchain agricultural traceability is mission-critical for a country. By leveraging and building upon blockchain's unique attributes, including tamper-evident, security hash crypto-data, and distributed ledger, we have proposed a prototype that allows traceability data to be reliably stored via blockchain while simultaneously being secured, with completeness auditing to enhance credibility. The result, the trusted auditing chain (TA chain), is a flexible solution that assures data security and solves challenges such as scalability and privacy-preserving. The TA chain works through Schnorr-style non-interactive Zero-knowledge proof to support security automatical choose privacy augmented. In addition, The TA chain can audit more than 1000 transactions within 1ms, and its error stabilizes below the 250 μs, which proves a security and fair traceability system to assure that data is distributed and reliably, and provably audited.
可追溯系统改变了食品安全管理和数据存储的方式。区块链追踪服务现在为客户提供了一种基础设施，使他们能够轻松地在线访问数据。然而，这些新功能存在局限性，例如缺乏透明度以及存在隐私和安全挑战。此外，随着对更灵活、私密且可追溯的安全数据解决方案的需求呈指数级持续增长，重新思考区块链农业可追溯性的当前结构对一个国家来说至关重要。通过利用和基于区块链的独特属性，包括防篡改、安全哈希加密数据和分布式账本，我们提出了一个原型，该原型允许可追溯数据通过区块链可靠存储，同时确保安全，并进行完整性审计以增强可信度。结果，可信审计链（TA链）是一种灵活的解决方案，可确保数据安全并解决诸如可扩展性和隐私保护等挑战。TA链通过施诺尔风格的非交互式零知识证明来工作，以支持自动选择增强隐私的安全性。此外，TA链可以在1毫秒内审计超过1000笔交易，其误差稳定在250微秒以下，这证明了一个安全且公平的可追溯系统，以确保数据得到分发、可靠且可证明地经过审计。
