Types

type ShufflingEpoch

type ShufflingEpoch struct {
	Epoch      Epoch
	Shuffling  []ValidatorIndex              // the active validator indices, shuffled into their committee
	Committees [SHARD_COUNT][]ValidatorIndex // slices of Shuffling, 1 per slot. Committee can be nil slice.
}

With a high amount of shards, or low amount of validators, some shards may not have a committee this epoch.

type ShufflingFeature

type ShufflingFeature struct {
	Meta interface {
		meta.Versioning
		meta.EpochSeed
		meta.ActiveIndices
		meta.CommitteeCount
		meta.CrosslinkTiming
	}
}
