信誉证明：区块链系统的另一种共识机制
Proof-of-Reputation: An Alternative Consensus Mechanism for Blockchain Systems
摘要：
区块链结合了其他技术，如密码学、网络和激励机制，以实现参与节点之间交易的创建、验证和记录。在区块链系统中使用共识算法来确定分布式节点之间的共享状态。任何基于区块链的系统的一个重要组成部分是其共识机制，它主要决定整个系统的性能和安全性。由于对等网络的开放性和动态性，节点可以随意加入和离开网络，极大地增加了网络的安全风险。因此，重要的是要有一个系统，可以检查恶意行为。在这项工作中，我们为基于区块链的系统提出了一种基于声誉的共识机制，即声誉证明（PoR），其中具有最高声誉值的节点最终成为决定区块链状态的共识组的一部分。
英文摘要：
Blockchains combine other technologies, such as cryptography, networking, and incentive mechanisms, to enable the creation, validation, and recording of transactions between participating nodes. A consensus algorithm is used in a blockchain system to determine the shared state among distributed nodes. An important component underlying any blockchain-based system is its consensus mechanism, which principally determines the performance and security of the overall system. As the nature of peer-to- peer(P2P) networks is open and dynamic, the security risk within that environment is greatly increased mostly because nodes can join and leave the network at will. Thus, it is important to have a system that can check against malicious behaviour. In this work, we propose a reputation-based consensus mechanism for blockchain-based systems, Proof-of-Reputation(PoR) where the nodes with the highest reputation values eventually become part of a consensus group that determines the state of the blockchain.
