// KZG ceremonies, the collection of witnesses to PoT pubkeys produce the

// with this is that there are n powers under G2 (excl. the case where PoT
// ceremonies _only_ have the first G2 power), and so the chance of collision
// by combination to a target value for s' is feasible such that a sum of a
// permutation of valid G2 powers could forge witness values to reach a
// a desired outcome, as there are matching pairs of the G1 and G2 powers to
// permute. When the number of G2 powers is low, or one, this reduces to the
// discrete log assumption and so the only viable attack is of
// O(sqrt(<bit size>)) per Pollard's Rho (barring any advancements), but in
// many cases the number of G2 powers is high enough such that n! naive
// combinations of additions are greater (and cheap, since the additions are
// first tested in G1) than the required time of testing the discrete log,
// and combined with many generated target values, significantly reduces the
// amount of time required to complete the attack. This means that in
// traditional KZG ceremonies, the last contributor to a ceremony can
// potentially control the secret. Or, we can just track the witnesses to the
// highest power in the ceremony and avoid the whole problem. :)
