Types

type LightDag

type LightDag struct {
	Name            string
	NumCaches       int // Maximum number of caches to keep before eviction (only init, don't modify)

	SeedEpochLength uint64 // ETC uses 30000 for the seed epoch length but 60000 for the rest
	NeedsL1         bool
	// contains filtered or unexported fields
}
