[Glossary](https://blnkfinance.com/glossary) AML # What is AML? AML AML is anti-money laundering: the program that watches how money moves after you onboard someone. KYC asks who they are. AML asks whether the activity looks like crime. A ledger does not decide that. It gives you the history an AML system reads: amounts, counterparties, velocity, and who owns the wallet. ## How does AML work in a product? You set rules: velocity, geographies, counterparties, product types. A system scores activity and raises alerts. A human or a model decides to hold, file, or close. The hold is a ledger action. The filing is not. ## AML vs KYC vs OFAC KYC is onboarding. OFAC is a list check on names and banks. AML is the ongoing watch. Teams collapse the three into “compliance.” The posts differ. An OFAC hit should block a specific transfer. An AML case may freeze an identity and every wallet under it. ## What do you need from the book? A complete, immutable path from source to destination, with identity on the wallets. If fees and hops are missing, the AML file is fiction. Do not run AML on the bank statement alone. The statement has one pot. ## How it works with Blnk Blnk is the history AML reads. Your rules engine is not inside the ledger. When a case says freeze, stop posting from those wallets in your app, or move the funds to a hold balance you control.
