BeaconChain represents beacon chain behavior

type SubnetSubscription

type SubnetSubscription struct {
	ValidatorIndex   types.ValidatorIndex
	CommitteeIndex   types.CommitteeIndex
	CommitteesAtSlot uint64
	Slot             types.Slot
	IsAggregator     bool
}

SubnetSubscription contains data to subscribe on subnets
