摘　　要：本文提出了一种基于幂域理论的信誉系统,通过分布式排列机制,在系统运行过程中动态地选择最有信誉的关键节点,如果其表现出不可接受的行为,这些节点将被动态更换,最后在不断交易的过程中,据其在本地的行为形成该节点在整个系统的信誉评价。We present a new P2P reputation system based on power law and power trust.According to distributed ranking system, the most reputable power nodes would be found.If it performances unacceptable behaviors, these node will be replaced dynamically in the running process.The global reputation will be formed in accordance with its behavior in the local area during the process of the transaction.
