为干线铁路扩展基于区块链的铁路控制系统原型：进度报告
Scaling a Blockchain-based Railway Control System Prototype for Mainline Railways: a Progress Report
摘要：
铁路运营需要控制系统来确保安全和效率，并协调基础设施要素，如道岔、信号和训练保护。为了与这些系统的传统方法竞争，提出了一种基于区块链的方法，旨在构建一个更具弹性，集成和成本效益的系统。此外，开发的基于区块链的架构能够在云等现成平台上运行安全相关和以安全为中心的业务逻辑，而不是在专门的（和昂贵的）安全硬件上运行。在实现了基于区块链的铁路控制系统的原型之后，将该方法扩展到现实世界的干线和支线运营需要对设计选择进行彻底的验证。在这份技术报告中，我们展示了性能计算、长期技术前景和法律规定的规范如何影响架构、技术选择和制造-购买-重用决策。
英文摘要：
Railway operations require control systems to ensure safety and efficiency, and to coordinate infrastructure elements such as switches, signals and train protection. To compete with the traditional approaches to these systems, a blockchain-based approach has been proposed, with the intent to build a more resilient, integrated and cost-efficient system. Additionally, the developed blockchain-based architecture enables to run safety-relevant and security-focused business logic on off-the-shelf platforms such as cloud, rather than on specialized (and expensive) secure hardware. After implementing a prototype of the blockchain-based railway control system, scaling the approach to real-world mainline and branch operations required a thorough validation of the design choices. In this technical report, we show how performance calculations, long-term technology perspectives and law-mandated norms have impacted the architecture, the technology choices, and the make-buy-reuse decisions.
