// TODO: This setup requires that the BN (beacon node) holds the block in state
// during the interval between the `GenerateProposalRequest` and the
// `SubmitProposalRequest`.
//
// This is sub-optimal as if a validator client switches BN during this process
// the block will be lost.
//
// This "stateful" method is being used presently because it's easier and
// requires less maintainence as the `BeaconBlock` definition changes.
