AI 中文摘要
现代供应链越来越依赖互不信任的异构利益相关者之间的敏感业务数据交换。传统集成方法通常依赖中心化中介或要求大量数据披露，这阻碍了协作、合规性与创新。我们提出一种用于供应链中隐私保护、无信任数据共享的通用参考架构。该架构结合了许可制分布式账本、基于物联网（IoT）的证据采集以及模块化隐私机制，以实现可控透明度：利益相关者可提取可验证的见解并支持审计，同时将数据暴露降至最低。我们在MoreMedDiet项目的背景下实例化该架构，该项目旨在推广可持续的从农场到餐桌食品体系及地中海饮食的应用。通过将MoreMedDiet用例映射到我们的架构中，我们展示了通道拓扑结构、物联网到账本的数据流以及基于智能合约的质量保证（QA）如何支持安全数据交换、透明度、互操作性和监管合规。我们的概念验证表明，去中心化身份（SSI）和W3C可验证凭证（VCs）可对Hyperledger Fabric通道提供可移植且可审计的访问治理。所得设计为包括农业食品和制药领域在内的多参与者供应链提供了可复用蓝图。此外，所实现的性能——向供应链下一个利益相关者出示一份可验证凭证耗时130毫秒——具有良好前景，证明了该方法在现实世界供应链环境中的潜在适用性。
英文摘要
Modern supply chains are increasingly dependent on the exchange of sensitive business data between heterogeneous stakeholders who do not trust each other. %under partial trust. Conventional integration approaches typically rely on centralized intermediaries or require extensive data disclosure, which hinders collaboration, compliance, and innovation. We propose a generic reference architecture for privacy preserving, trustless data sharing in supply chains. The architecture combines permissioned distributed ledgers, IoT-based evidence ingestion, and modular privacy mechanisms to enable controlled transparency: stakeholders can extract verifiable insights and support audits while minimizing data exposure. We instantiate the architecture in the context of the MoreMedDiet project, which promotes sustainable farm-to-fork food systems and adoption of the Mediterranean diet. By mapping the MoreMedDiet use case into our architecture, we demonstrate how channel topologies, IoT-to-ledger data flows, and smart contract-based quality assurance (QA) can support secure data exchange, transparency, interoperability, and regulatory alignment. Our proof-of-concept illustrates how Self-Sovereign Identity (SSI) and W3C Verifiable Credentials (VCs) can provide portable and auditable access governance over Hyperledger Fabric channels. The resulting design offers a reusable blueprint for multi-actor supply chains, including agri-food and pharmaceutical domains. Moreover, the performance achieved -- presenting a verified credential to the next stakeholder in the supply chain in 130 ms -- is promising and demonstrates the potential applicability of the approach in real-world supply chain environments.
