I'm a bit late but https://tornado.cash is cool
If bitcoin is turing complete it means you could build that inside an UXTO. Anyone could deposit/withdram money to that UXTO and pay eachothers with that UXTO (meaning that when I pay someone the money won't leave the UXTO).
I'm not sure if that's possible. But if it is, it's insane
lol you gonna build them? I do want to see someone build FOMO3D on BSV, but do it in a gray area where it's neither legal (it's never completely legal) nor completely illegal.
