Module solana_sdk::epoch_schedule

Configuration for epochs and slots.

Epochs mark a period of time composed of slots, for which a particular leader schedule is in effect. The epoch schedule determines the length of epochs, and the timing of the next leader-schedule selection.

The epoch schedule does not change during the life of a blockchain, though the length of an epoch does — during the initial launch of the chain there is a “warmup” period, where epochs are short, with subsequent epochs increasing in slots until they last for DEFAULT_SLOTS_PER_EPOCH.

Structs

• EpochSchedule

Constants

• DEFAULT_LEADER_SCHEDULE_SLOT_OFFSET
  The default number of slots before an epoch starts to calculate the leader schedule.
• DEFAULT_SLOTS_PER_EPOCH
  The number of slots per epoch after initial network warmup.
• MAX_LEADER_SCHEDULE_EPOCH_OFFSET
  The maximum number of slots before an epoch starts to calculate the leader schedule.
• MINIMUM_SLOTS_PER_EPOCH
  The minimum number of slots per epoch during the warmup period.

Type Aliases

• Epoch
  The unit of time a given leader schedule is honored.
• Slot
  The unit of time given to a leader for encoding a block.
