OpenDSU：PharmaLedger中的数字主权
OpenDSU: Digital Sovereignty in PharmaLedger
摘要：
分布式账本网络，主要是那些基于区块链技术的网络，目前正预示着下一代计算机系统，旨在满足现代用户的需求。近年来，区块链、脱链策略以及去中心化和自主身份系统的几种技术发展如此之快，以至于协议的标准化滞后，严重阻碍了不同方法的互操作性。此外，目前大多数分布式账本解决方案都集中在家庭用户或企业用例场景上，未能提供满足两者需求的集成解决方案。在此，我们介绍OpenDSU平台，该平台允许在域中组织并可能以分层方式级联的通用区块链技术进行互操作。为了实现这种灵活性，我们无缝集成了一组精心设计的OpenDSU组件，以编排链下数据，这些数据具有粒度解析和加密安全的访问级别，这些访问级别与不同域的主权身份嵌套。将我们的平台应用于PharmaLedger，这是一个用于制药行业和医疗保健数据处理标准化的欧洲网络，我们证明OpenDSU可以在性能和处理实质上不同的业务策略方面应对异构用例的通用需求。重要的是，虽然可用的解决方案通常需要一组预定义的固定组件，但OpenDSU中不存在对区块链技术或身份系统的供应商锁定限制，使构建在其上的系统能够灵活地适应未来发展的新标准。
英文摘要：
Distributed ledger networks, chiefly those based on blockchain technologies, currently are heralding a next generation of computer systems that aims to suit modern users' demands. Over the recent years, several technologies for blockchains, off-chaining strategies, as well as decentralised and respectively self-sovereign identity systems have shot up so fast that standardisation of the protocols is lagging behind, severely hampering the interoperability of different approaches. Moreover, most of the currently available solutions for distributed ledgers focus on either home users or enterprise use case scenarios, failing to provide integrative solutions addressing the needs of both. Herein we introduce the OpenDSU platform that allows to interoperate generic blockchain technologies, organised - and possibly cascaded in a hierarchical fashion - in domains. To achieve this flexibility, we seamlessly integrated a set of well conceived OpenDSU components to orchestrate off-chain data with granularly resolved and cryptographically secure access levels that are nested with sovereign identities across the different domains. Employing our platform to PharmaLedger, an inter-European network for the standardisation of data handling in the pharmaceutical industry and in healthcare, we demonstrate that OpenDSU can cope with generic demands of heterogeneous use cases in both, performance and handling substantially different business policies. Importantly, whereas available solutions commonly require a pre-defined and fixed set of components, no such vendor lock-in restrictions on the blockchain technology or identity system exist in OpenDSU, making systems built on it flexibly adaptable to new standards evolving in the future.
