Functions ¶

func GenerateProof ¶

func GenerateProof(
	ctx context.Context,
	leavesCounter prometheus.Counter,
	treeCfg TreeConfig,
	labelHashFunc func(data []byte) []byte,
	merkleHashFunc merkle.HashFunc,
	deadline time.Time,
	securityParam uint8,
	persist persistFunc,
) (uint64, *shared.MerkleProof, error)

GenerateProof generates the Proof of Sequential Work. It stops when the given deadline is reached.

func GenerateProofRecovery ¶

func GenerateProofRecovery(
	ctx context.Context,
	leavesCounter prometheus.Counter,
	treeCfg TreeConfig,
	labelHashFunc func(data []byte) []byte,
	merkleHashFunc merkle.HashFunc,
	deadline time.Time,
	securityParam uint8,
	nextLeafID uint64,
	persist persistFunc,
) (uint64, *shared.MerkleProof, error)

GenerateProofRecovery recovers proof generation, from a given 'nextLeafID'.

func GenerateProofWithoutPersistency ¶

func GenerateProofWithoutPersistency(
	ctx context.Context,
	treeCfg TreeConfig,
	labelHashFunc func(data []byte) []byte,
	merkleHashFunc merkle.HashFunc,
	deadline time.Time,
	securityParam uint8,
) (uint64, *shared.MerkleProof, error)

GenerateProofWithoutPersistency calls GenerateProof with disabled persistency functionality. Tree recovery will not be possible. Meant to be used for testing purposes only. It doesn't expose metrics too.

func GetLayerFactory ¶ added in v0.9.4

func GetLayerFactory(minMemoryLayer uint, datadir string, fileWriterBufSize uint) cache.LayerFactory

GetLayerFactory creates a merkle LayerFactory. The minMemoryLayer determines the threshold below which layers are saved on-disk, while layers equal and above - in-memory.

Types ¶

type TreeConfig ¶ added in v0.6.1

type TreeConfig struct {
	MinMemoryLayer    uint
	Datadir           string
	FileWriterBufSize uint
}
