Block Generators (a role taken outside of the Provisioner) participate in a non-interactive lottery to be able to forge a candidate block. In order to decide which Block to select among the various candidates, the Block Generators propagate a score associated with their candidate block, which is the result of the lottery run in a non-interactive fashion. Together with the score, the Block Generators publish a zero-knowledge proof of correctness of the score computation according to the rules outlined in the Blind Bid algorithm.
