The emergence of peer-to-peer (P2P) systems has enabled rapiddeployment of Internet-scale distributed applications over theInternet. This project focuses on cooperative peer-to-peer systems, inwhich peer nodes form a "community of common interest" with sharedgoals and mutual benefits. Services that can be supported bycooperative P2P systems cover the gamut of networkedapplications and distributed computing. Since the value and utility of a cooperative P2P system is in theservice it offers to its users, ensuring its correct and efficientoperation despite the existence of potentially untrustworthy nodes isof utmost importance. The goal of this project is to understand and address the challengesand problems in building large-scale, robust cooperative P2P systemsthat are trustworthy, accountable and secure. The project includesdeveloping implementations of several innovative concepts andmechanisms: efficient and correct "Distributed Hash Table" routing,randomly rotating "witness" nodes, and virtualized protocolevaluation.

对等（P2P）系统的出现使得Internet规模的分布式应用能够在Internet上快速部署。该项目的重点是合作对等系统，其中对等节点形成一个具有共同目标和互利的“共同利益社区”。 协作P2P系统所支持的服务涵盖了网络应用和分布式计算的所有领域。 由于协作P2P系统的价值和实用性在于它为用户提供的服务，因此即使存在潜在的不可信任节点，也要确保其正确、高效地运行。 该项目的目标是了解和解决在构建大规模的，健壮的合作P2P系统是值得信赖的，负责任的和安全的挑战和问题。 该项目包括开发几个创新概念和机制的实现：高效和正确的“分布式哈希表”路由，随机旋转的“见证”节点，以及虚拟化协议评估。
