Abstract：Tosolve the problem of untrusted nodes inexisting relay-based cros-chain mechanisms，this paper proposed areputationmanagement modelforrelaychain nodes.The modelaimedtopredictthe likelihoodof malicious behaviorovertime.It improvedthePowerTrustalgorithmandintegrateditintotherelaychainframework.ItintroducedadynamicMarkovdecision process tooptimizethedistributed hash mechanism.Italsousedstrong nodes toacceleratereputationagregation.Themodel assessed node trustworthinessbyanalyzingrecenttransactionrecordsand node-specificatributes.Experiments showthatthe method effctivelycalculates nodereputationovertime.Itquicklyadjusts reputationscores whennodesactmaliciously.Itselects reliable relay chain nodes for cross-chain transactions and improves overall system security.
