Thanks, and in the spirit of doing something useful and not only complaining, I opened an issue on your coinjoin-workshop repo to get a bit more into the weeds of how blame would work for that kind of protocol.. well, 'useful' might not be the right word but anyway ;)
Thank you waxwing, I added your correction and gave a response in some follow up tweets. https://twitter.com/super_testnet/status/1788287748618723651
I copy/paste my response here:
Joinmarket's coordination model is unique and awesome because the coordinator is just one of the people in the coinjoin (the "taker"), changes in ~every round, and does not take a fee -- rather, they pay fees to the makers.
I do not like that the coordinator in joinmarket can map everyone's inputs to their outputs. This could be fixed with blind signatures and I am happy to help make this happen if it would be a welcome change in joinmarket. I also do not like that there *is* a coordinator.
If it's possible to do this stuff without a coordinator, why have one? A deterministic protocol like emessbee removes variables introduced through the coordination mechanism. And it also might keep some people out of jail til the feds criminalize mere participation too.
