Expand description

Consensus constants

Fields§

§confirmation_depth_k: BlockNumber

Depth K after which a block enters the recorded history

§block_authoring_delay: SlotNumber

Number of slots between slot arrival and when the corresponding block can be produced

§pot: PotConsensusConstants

Proof-of-time consensus constants

§retarget_interval: BlockNumber

Period of time in blocks after which the solution range is adjusted

§slot_probability: (u64, u64)

Slot probability

§slot_duration: SlotDuration

The slot duration in milliseconds

§recent_segments: HistorySize

Number of latest archived segments that are considered “recent history”

§recent_history_fraction: (HistorySize, HistorySize)

Fraction of pieces from the “recent history” (recent_segments) in each sector

§min_sector_lifetime: HistorySize

Minimum lifetime of a plotted sector, measured in archived segments

§max_block_timestamp_drift: BlockTimestamp

Max block timestamp drift allowed

§shard_rotation_interval: BlockNumber

Number of beacon chain blocks between shard rotations.

Every this number of beacon chain blocks PoT entropy is taken to calculate the next shard assignment.

§shard_rotation_delay: BlockNumber

Delay in beacon chain blocks for the next shard rotation.

Delay after shard assignment is revealed before it actually takes effect (essentially the amount of time for a node to sync the corresponding shard).
