The Bitcoin integration and ckBTC is already controlled by the NNS, so it’s the NNS DAO and NNS that could be held responsible if there is a regulatory crackdown.
I think it’s prudent to get ahead of this and put in place a KYT system, where the system itself is owned by a DAO and transparent to both regulators and ckBTC users.
I’d be in favor of this KYT software system to be decoupled from the protocol itself and to go through an SNS, allowing ckBTC users, dapps, and exchanges the opportunity to invest and have a say in the software and process by which “tainted” UTXOs are defined/identified.
