Summary

BlockAthena is a forensic framework for analyzing long-term on-chain crimes in account-based blockchains. It segments long-term transaction topology into subgraphs based on crime evolution periods, modeling direct and co-occurrence transactional behaviors. Experiments report an average 18% improvement in F1-score and up to an 80% reduction in memory overhead compared to the best-performing baseline.
