CSR---PDOS: Byzantine faults in a rational world

这个项目的目标是发展理论和实践来构建拜占庭和理性容错（BRFT）分布式系统。BRFT系统在理性节点的集合上适当地操作，所述理性节点可以任意地偏离任何建议的协议，以便最大化它们自己的净利益，并且它还容忍少量的 拜占庭节点可以出于任何原因（包括故障、错误配置或恶意）任意偏离任何建议的协议。 BRFT旨在对跨多个管理域的协作系统和应用程序进行建模-示例包括Internet路由、无线网状路由、P2P网络中的文件分发、归档存储或协作备份。目前还没有令人满意的方法来模拟这样的系统，在没有中央权威的情况下，正确和错误节点之间的经典二分法变得不够：所有节点，而不仅仅是错误的节点，可能会偏离建议的协议。

The goal of this project is to develop the theory and practice for constructing Byzantine and Rational Fault Tolerant (BRFT) distributed systems. A BRFT system operates properly upon a collection of rational nodes that can arbitrarily deviate from any suggested protocol in order to maximize their own net benefits, and it also tolerates a small number of Byzantine nodes that can arbitrarily deviate from any suggested protocol for any reason including malfunction, misconfiguration, or malice. BRFT is intended to model cooperative systems and applications that span multiple administrative domains---examples include Internet routing, wireless mesh routing, file distribution in P2P networks, archival storage, or cooperative backup. Currently there exists no satisfactory way to model systems such as these, where, absent a central authority, the classical dichotomy between correct and faulty nodes becomes inadequate: all nodes, not just the faulty ones, may depart from the suggested protocol.
