Fields§
§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: u64
The first epoch after the warmup period.
Basically: log2(slots_per_epoch) - log2(MINIMUM_SLOTS_PER_EPOCH)
.
first_normal_slot: u64
The first slot after the warmup period.
Basically: MINIMUM_SLOTS_PER_EPOCH * (2.pow(first_normal_epoch) - 1)
.
