 The justification of a checkpoint can sometimes finalize blocks from two or more epochs ago, especially during periods of high latency, network partitions, or attacks, You can find more such cases, discussed in the Gasper paper. These scenarios are exceptional and not the norm.

 Validators submit one attestation per epoch, containing both an LMD GHOST and an FFG vote. These attestations have 32 chances per epoch for inclusion on-chain, with earlier inclusions receiving higher rewards. This means a validator may have two attestations included on-chain in a single epoch. Validators are rewarded the most when their attestation is included on-chain at their assigned slot; later inclusion has a decayed reward. To give validators time to prepare, they are assigned to committees one epoch in advance. Proposers are only assigned to slots once the epoch starts. Nonetheless, [secret leader election](https://ethresear.ch/t/low-overhead-secret-single-leader-election/5994) research aims to mitigate attacks or bribing of proposers.
