AFAIK random.org offers to run lotteries for you (for a fee), but all participants still need to trust them to generate the numbers fairly. It’s obviously unlikely that there would in fact be any problem here, but we’re erring on the side of having something that’s easier for an external party to inspect.
Trusting random.org doesn’t seem so bad (probably a bit better than trusting IRIS, since IRIS isn’t in the business of claiming to be non-manipulable). I don’t know if they support arbitrary winning probabilities for draws, but probably there is some way to make it work.
(That does seem strictly worse than hashing powerball numbers though, which seem more trustworthy than random.org and easier to get.)
