Struct sp_consensus_babe::BabeGenesisConfiguration [−][src]
pub struct BabeGenesisConfiguration { pub slot_duration: u64, pub epoch_length: u64, pub c: (u64, u64), pub genesis_authorities: Vec<(AuthorityId, BabeAuthorityWeight)>, pub randomness: Randomness, pub allowed_slots: AllowedSlots, }
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.
The authorities for the genesis epoch.
randomness: Randomness
The randomness for the genesis epoch.
allowed_slots: AllowedSlots
Type of allowed slots.
