ethereum rng:
probability 0 1 ... 100
prob = probability*2^32

max number of owners in a branch of rep. issues w/ sending rep etc
zeroing of array values (e.g. people in the rep index after they have 0 rep left)
consensus bond mechanism cheaper + reporting on outcome + if not certain onchain as fallback
possibly enable people to choose their own resolution scripts
