Yes, I hate the idea of future public lotteries, published ahead of time. The entire idea is to be resistant to a nation-state attack; lotteries seem pretty far down the chain.<p>If you&#x27;re in love with lotteries, you could do something like order all lotteries in the world in a published list, and then choose them based on the last digits of bitcoin block hashes over a certain period.<p>I&#x27;m not sure what bitrate you could get through sunspots, but I agree we shouldn&#x27;t worry about subversion from that angle.
