A Bitcoin AML score is a triage aid built from UTXO graph evidence. It ranks which BTC wallet needs manual review; it is not a cleanliness certificate.
Evidence enters before any band is assigned
The model maps inputs and outputs to attributed entities: sanctioned coins, darknet clusters, CoinJoin coordinators, ransomware payout addresses, and stolen-funds trails from cases such as Mt.Gox forensics and the Bitfinex recovery work. Direction and value share matter as much as the entity name.
Bitcoin-specific signals inside the total
Shared-input clustering, peel-chain distance, and CoinJoin breaks are BTC-native inputs. A remote hop through a broad market neighborhood should not receive the same weight as a direct sanctioned payment. Keep category contributions visible so analysts can challenge stale tags.
Read the four bands as review priorities
0-25 low: no material flags in available data. 26-59 medium: collect context on limited or indirect exposure. 60-84 high: investigate the material finding before processing funds. 85-100 critical: stop the routine flow and escalate direct severe exposure.
Next step
Open the category breakdown beside the number and document the transactions behind material flags. Policy and jurisdiction decide the final action. This information is not legal or financial advice.
