Result Details

The result field will be an object containing:
  • slotsPerEpoch: <u64>
    • The maximum number of slots in each epoch
    • Defines the total slots allocated for a single epoch
  • leaderScheduleSlotOffset: <u64>
    • Number of slots before the beginning of an epoch used to calculate the leader schedule
    • Determines when the leader schedule for an upcoming epoch is computed
  • warmup: <bool>
    • Indicates whether epochs start short and gradually grow
    • true means the initial epochs have fewer slots before reaching full length
  • firstNormalEpoch: <u64>
    • The first epoch with a standard (full) number of slots
    • Calculated as log2(slotsPerEpoch) - log2(MINIMUM_SLOTS_PER_EPOCH)
  • firstNormalSlot: <u64>
    • The first slot of the first normal-length epoch
    • Calculated as MINIMUM_SLOTS_PER_EPOCH * (2^firstNormalEpoch - 1)
