การวิเคราะห์ On-Chain และการให้คะแนนความเสี่ยง AML สำหรับ DeFi?

It's a mix, but the trend is definitely towards more complex behavioral models. Identifying known illicit addresses is table stakes, but the real challenge is proactively spotting suspicious activity from unflagged wallets before they become a problem.

That's a great question. I think a lot of firms are still figuring out the right balance, but the trend seems to be towards more complex behavioral models for new wallets, beyond just flagging known illicit addresses. It's a tricky balance between effective AML and not overly burdening legitimate users.

Most are focused on known illicit addresses and direct exposure. Behavioral models are still pretty nascent for new wallets, primarily because the data sets are messy and defining 'risky' behavior without false positives is incredibly hard.

It's definitely a mix. Beyond known addresses, many are developing heuristics for suspicious activity, like rapid transfers to multiple new wallets or large, unexplained inbound flows from mixers. The challenge is balancing accuracy with false positives.
