我们描述了PeerReview，该系统在分布式系统中提供问责制。 PEERREVIEW确保最终检测到由正确节点观察到的效果的拜占庭断层，并与故障节点无可辩驳。同时，PeerReview确保正确的节点可以始终捍卫自己免受虚假指控。对于跨越多个管理域的系统，这些保证尤其重要，这些系统可能彼此不信任。PeerReview可以通过维护每个节点发送和接收的消息的安全记录来起作用。该记录是自动检测到节点的行为何时偏离给定参考实现的行为，从而暴露出故障节点。 PEERREVIEW广泛适用：仅要求正确的节点的操作是确定性的，节点可以签名消息，并且每个节点都会通过正确的节点定期检查。我们通过将其应用于三种不同类型的分布式系统：网络文件系统，点对点系统和覆盖多播系统来证明PEERREVIEW是实用的。
We describe PeerReview, a system that provides accountability in distributed systems. PeerReview ensures that Byzantine faults whose effects are observed by a correct node are eventually detected and irrefutably linked to a faulty node. At the same time, PeerReview ensures that a correct node can always defend itself against false accusations. These guarantees are particularly important for systems that span multiple administrative domains, which may not trust each other.PeerReview works by maintaining a secure record of the messages sent and received by each node. The record isused to automatically detect when a node's behavior deviates from that of a given reference implementation, thus exposing faulty nodes. PeerReview is widely applicable: it only requires that a correct node's actions are deterministic, that nodes can sign messages, and that each node is periodically checked by a correct node. We demonstrate that PeerReview is practical by applying it to three different types of distributed systems: a network filesystem, a peer-to-peer system, and an overlay multicast system.
