基于混合链的原子性匿名竞拍系统
Atomic anonymous auction system based on the hybrid chain
摘要
Abstract
To address the limitations of existing blockchain-based auction schemes regarding efficiency,privacy preservation,and cross-chain atomicity,this paper proposes an atomic anonymous auction system based on a hybrid chain architecture.First,to enhance system scalability and achieve load balancing,this paper designs a hybrid blockchain architecture comprising a main chain and multiple sub-chains thus effectively mitigating the issues of data confusion and system overload in single-chain architectures.Second,to address the risk of privacy leakage caused by the frequent use of user certificate public keys,a traceable ring signature-based certificate management scheme is proposed which ensures anonymity while enabling identity tracing under compliant conditions.Furthermore,targeting the challenges of data synchronization and transaction atomicity in multi-chain environments,this paper designs an auction protocol based on hashed time-lock contracts.By utilizing the synergistic mechanism of time locks and hash locks,the atomicity of auction opera-tions is guaranteed.To prevent malicious bidding behaviors,a dynamic deposit mechanism based on the Bayesian Nash Equilibrium theory is designed to ensure that the expected payoff of malicious behavior remains lower than the deposit cost.Experimental results demonstrate that in high-frequency and large-scale auction scenarios,the proposed scheme outperforms comparative schemes in transaction throughput,while keeping CPU usage within a reasonable range.Additionally,the deposit mechanism effectively constrains malicious bidders,making their returns when acting maliciously significantly lower than those of honest participants.关键词
