What is blockchain analytics in compliance terms?
Tooling that links on-chain addresses to real-world entity attributions (exchanges, mixers, sanctioned services, ransomware operators, darknet markets) and traces fund flows. Used for transaction monitoring, sanctions exposure assessment (especially after OFAC designations of mixers like Tornado Cash and addresses associated with North Korean actors), SAR / SMR investigations, and pre-transaction risk scoring. Major providers include Chainalysis, TRM Labs, Elliptic, and Crystal.
