Ethena's USDe I think doesn't have blacklist function (still not sure) on their contract but USD0 which is introduced by Usual and supposedly branding themselves as decentralized apparently also have blacklist function
but moving forward I'd expect any decentralized non algorithmic stablecoin in existence will implement blacklist function because that's their only option.
That's the thing. These so-called decentralized protocols and stablecoins adopt KYC/AML techniques, making them no different than traditional banking. If they want to make a difference, they'd need to be as free (as in freedom) and open as possible. Sadly, the number of truly-decentralized apps and stablecoins is diminishing each day. If this keeps up, all "De-Fi" will turn centralized. They should change the name of the term into "Ce-Fi" or "CeDe-Fi" (which stands for centralized/decentralized finance).
It's governments' game now. We should have expected this sooner. Especially with stablecoins tied to the value of centralized Fiat currencies. I guess most people don't care because they're in it for the money. Convenience goes above all else. At least DAI/Maker's code is open source. What's stopping someone from making a truly-decentralized fork in the long run?
