Can you give a comparison of supernet, joinmarket, samourai whirlpool, wabisabi of wasabi
And whether your protocol is decentralised enough with no toxic changes
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.

By "supernet" I assume you mean Emessbee
The advantages of Emessbee are:
- there is no coordinator, so there is no one to shut down or "leave country X"
- due to no coordinator, there is no coordinator fee, so Emessbee is cheaper than alternative coinjoin implementations (except joinmarket, which pays you to coinjoin)
Drawbacks compared to Wasabi:
Wasabi has no toxic change, Emessbee does
Drawbacks compared to Samourai:
In Samourai you only pay for your first coinjoin, the other ones are free (for you). In Emessbee you pay for every coinjoin, so over time it's more expensive than Samourai
Drawbacks compared to Joinmarket:
Joinmarket pays you to coinjoin, Emessbee does not
> And whether your protocol is decentralised enough with no toxic changes
Emessbee does have toxic change
Also worth pointing out: Emessbee is not complete coinjoin software and is not ready for use on mainnet. It only demonstrates that doing a coinjoin without a coordinator is feasible and has significant benefits. IMO the other coinjoin implementations are better than Emessbee (because they are actually ready to use right now) and you should use those, not Emessbee. But I do think it would be good if the other coinjoin implementations "upgraded" to use Emessbee's coordination protocol instead of using a coordinator.
