Expand description

Configuration data used by the BABE consensus engine.

Fields

slot_duration: u64

The slot duration in milliseconds for BABE. Currently, only the value provided by this type at genesis will be used.

Dynamic slot duration may be supported in the future.

epoch_length: u64

The duration of epochs in slots.

c: (u64, u64)

A constant value that is used in the threshold calculation formula. Expressed as a rational where the first member of the tuple is the numerator and the second is the denominator. The rational should represent a value between 0 and 1. In the threshold formula calculation, 1 - c represents the probability of a slot being empty.

genesis_authorities: Vec<(AuthorityId, BabeAuthorityWeight)>

The authorities for the genesis epoch.

randomness: Randomness

The randomness for the genesis epoch.

allowed_slots: AllowedSlots

Type of allowed slots.
