Functions

func GenVRF

	ctx context.Context,

Types

type Config 

type Config struct {
	// ConfidenceParam specifies how many layers into the epoch hare uses active set generated in the previous epoch.
	// For example, if epoch size is 100 and confidence is 10 hare will use previous active set for layers 0-9
	// and then generate a new activeset.
	//
	// This was done like that so that we have higher `confidence` that hare will succeed atleast
	// once during this interval. If it doesn't we have to provide centralized fallback.
	ConfidenceParam uint32 `mapstructure:"eligibility-confidence-param"`
