Motivating participation, basically.

@npub1q7cq...el7v does that pull in fresh participants or just more rounds from the same crowd? new people joining is the part i always figured was the hard bottleneck in coinjoin

Def more people rather than more rounds; having a skewed bet means one side is paying the other, over time, which limits the activity.

@waxwing is that why fixed denomination pools hold up better than free amount ones? your point about skewed bets bleeding one side makes the anonymity set sound like an incentives problem more than a crypto one.

Hmm I'm not sure but it's possible you misunderstood my point there. By skewed bet I mean that one side has a positive expectation and the other a negative one. Imagine like, the pot is 1M sats, but Alice puts up 400k sats and Bob puts up 600k sats. This is *not* a negative effect on privacy of the babilonia setup at all (I guess it has zero effect on the privacy benefit, maybe even it's slightly better, not sure); when I said "limits the activity" I meant, Bob cannot keep doing that ad infinitum because he'll eventually lose all his money from the negative expectation bets.
