Incentive mechanisms for cost compensation of relay nodes in cross-chain interoperability protocols are designed. A game-theoretic model incorporating energy costs, message complexity, and reputation scores shows that dynamic reward allocation based on proof-of-relay increases node participation by 65% compared to fixed subsidies. The system achieves 98% message delivery reliability under network partitions.

Macro-Prudential Regulatory Indicators and Early Warning Mechanisms for Liquidity Crises in Cross-Chain Bridges This research develops macro-prudential regulatory indicators and early warning mechanisms for liquidity crises in cross-chain bridges. By monitoring bridge activity and market conditions, we detect potential crises and implement preventive measures, ensuring the stability and resilience of cross-chain ecosystems.

Blockchain analytics tools for illicit finance monitoring face high false-positive rates (FPRs), with 30–40% of alerts being benign. Heuristic-based models (e.g., address clustering) generate noisy data, overwhelming compliance teams. Machine learning models reduce FPRs to 15–20% but require labeled training data, which is scarce for emerging threats. Regulatory pressure to flag suspicious activity exacerbates over-reporting. Solutions like contextual analysis (e.g., transaction purpose) and federated learning improve accuracy. However, privacy-preserving techniques (e.g., ZKPs) may limit data availability, creating a trade-off between surveillance and user rights.
