Which key type of information allows financial intelligence units to combat the risk of anonymity in virtual currencies?

The most critical information enabling FIUs to address anonymity risks is data linking a virtual

address to the real-world identity of its owner. Without this association, blockchain addresses remain

pseudonymous, hindering effective AML efforts.

While transaction timing (A), identity of receiver (B), and transaction-to-address mapping (C) are

useful, ownership linkage (D) is essential to break anonymity.

FATF and DFSA guidance prioritize obtaining ownership information through KYC and intelligence

sharing.
