Types ¶

type Config ¶

type Config struct {
	MinNumUnits   uint32
	MaxNumUnits   uint32
	BitsPerLabel  uint8
	LabelsPerUnit uint64

	K1 uint32 // K1 specifies the difficulty for a label to be a candidate for a proof.
	K2 uint32 // K2 is the number of labels below the required difficulty required for a proof.
	B  uint32 // B is the number of labels used per AES invocation when generating a proof. Lower values speed up verification, higher values proof generation.
	N  uint32 // N is the number of nonces tried at the same time when generating a proof.

}

func DefaultConfig ¶

func DefaultConfig() Config

type InitOpts ¶

type InitOpts struct {
	DataDir           string
	NumUnits          uint32
	MaxFileSize       uint64
	ComputeProviderID int
	Throttle          bool
}
