Dfinity contains a randomness beacon which generates new randomness by VRF with input from new confirmed block. They use the randomness to select a leader and electors for a round. By hypergeometric distribution, Dfinity only samples hundred of users to notary a block instead of all users, and this is correct with high probability. But this reduces the tolerance ability of Byzantine. For example, to achieve the majority of users is non-Byzantine with probability less than , it needs to sample at least 423 users from 10K users with maximum 1/3 Byzantine users. However, Dfinity is chain-based, so its throughput is limited. ## EOS -- cgit v1.2.3
