I've thought about trustless lotteries quite a bit, and haven't really came up with a solution that works without using head-to-head brackets.

>A bad actor can't change the outcome of a flip but could prevent it from resolving.

The post glosses over this but it can get pretty bad. E.g. 99 actors have revealed their seeds and then the 100th decides whether to reveal or not, based on whether they or their confederates will be the winner after that final reveal.
