On-Chain Forensics

Definition ∞ On-chain forensics is the practice of examining transaction records and other data directly on a blockchain to investigate illicit activities or trace asset flows. This process involves analyzing transaction histories, wallet associations, and smart contract interactions to reconstruct events. It is a critical tool for law enforcement and security professionals in the digital asset space.
Context ∞ The application of on-chain forensics is increasingly prominent in news reports concerning cryptocurrency-related fraud, money laundering, and asset recovery efforts. Discussions often highlight the challenges and successes of tracing funds through complex transaction networks and the collaboration between forensic analysts and regulatory bodies. The development of sophisticated analytical tools and techniques is continuously shaping the effectiveness of these investigations.
