BlockAthena: A Scalable Approach for Long-Term Blockchain Crimes Analysis

BlockAthena is a new forensic framework designed to detect long-term crimes on blockchains (distributed ledgers that record transactions) by analyzing transaction patterns over extended periods. The system identifies criminal behavior by recognizing botnet-style activity (coordinated malicious networks) and APT tactics (advanced persistent threat methods used by sophisticated attackers), segmenting transaction data into meaningful chunks based on crime phases, and using graph analysis to spot suspicious patterns while using less computer memory than previous approaches.
