Struct pallet_babe::CurrentBlockRandomness
source · pub struct CurrentBlockRandomness<T>(_);👎Deprecated: Should not be relied upon for correctness, will not provide fresh randomness for the current block. Please use
ParentBlockRandomness instead.Expand description
Randomness produced semi-freshly with each block, but inherits limitations of
RandomnessFromTwoEpochsAgo from which it derives.
