I responded to that post, how did you miss it?
That's the insufficient response.
Wouldn't the coordinator be able to gain extra information from pairs of inputs that refuse to participate with each other?
It can conclude that Alice is probably remixing in the coinjoin she refused to join, but that's all. The coordinator doesn't know which one is her remixed coin.
As I previously said, I'm not a Whirlpool expert. My insights stem from observations of technically proficient people who discuss Samourai. I don't completely trust Samourai after reading about what's been said and done throughout the years. Usually, people behind Samourai typically refute criticisms of its ineffectiveness. Could you give me an article that would justify your critique on Whirlpool?
