slots_per_epoch: u64

The maximum number of slots in each epoch.

leader_schedule_slot_offset: u64

A number of slots before beginning of an epoch to calculate a leader schedule for that epoch

warmup: bool

whether epochs start short and grow

first_normal_epoch: Epoch

basically: log2(slots_per_epoch) - log2(MINIMUM_SLOTS_PER_EPOCH)

first_normal_slot: Slot

basically: MINIMUM_SLOTS_PER_EPOCH * (2.pow(first_normal_epoch) - 1)
