Towards a Dynamic Reputation Management Scheme for Cross-chain Transactions

EasyChair Preprint 8508

Abstract

Recently, research communities have dedicated their efforts to the development of versatile and innovative Blockchain-based application systems. These systems are usually independent and thus difficult to be integrated and cooperated with each other during cross-chain transactions in terms of the interoperability perspective. In addition, there may be potential risks once external malicious attackers desire to control or manipulate nodes in cross-chain systems. It is necessary to have a solution preventing users’ misbehaviors during the process of information and value exchange among different blockchains. In this paper, we propose a dynamic reputation management scheme which can effectively detect misbehaviors and identify potential security risks during cross-chain transactions. Our scheme conducts a mechanism evaluating reputation and trustworthiness of nodes and chains, respectively, through their current state and transactions history. This characteristic can help any cross-chains system well-react and be resistant against ongoing-endangered behaviors within a reasonable computation time.
