基于PowerTrust算法的中继链信誉管理模型
Reputation management model of relay chain based on PowerTrust algorithm
摘要
Abstract
To solve the problem of untrusted nodes in existing relay-based cross-chain mechanisms,this paper proposed a re-putation management model for relay chain nodes.The model aimed to predict the likelihood of malicious behavior over time.It improved the PowerTrust algorithm and integrated it into the relay chain framework.It introduced a dynamic Markov decision process to optimize the distributed hash mechanism.It also used strong nodes to accelerate reputation aggregation.The model assessed node trustworthiness by analyzing recent transaction records and node-specific attributes.Experiments show that the method effectively calculates node reputation over time.It quickly adjusts reputation scores when nodes act maliciously.It se-lects reliable relay chain nodes for cross-chain transactions and improves overall system security.关键词
