Functions ¶

func VerifySignature ¶

func VerifySignature(sig *Signature, pk *PublicKey, msg []byte) (bool, error)

func VerifySignatureBytes ¶

func VerifySignatureBytes(msg [32]byte, sigBytes, pkBytes []byte) (ok bool, err error)

Types ¶

type ProcessManagerMetrics ¶

type ProcessManagerMetrics struct {
	VerifyTiming   *prometheus.HistogramVec
	RunningWorkers *prometheus.GaugeVec
}

type PublicKey ¶ added in v0.6.0

type PublicKey = bls12381.G1Affine

func PublicKeyFromBytes ¶ added in v0.6.0

func PublicKeyFromBytes(pkBytes []byte) (*PublicKey, error)

type Request ¶

type Request struct {
	Signature [96]byte
	Pubkey    [48]byte
	Msg       [32]byte
	// Unique identifier of payload
	// if needed to be passed back in response
	ID       int
	Response *StoreResp
}

VerifyReq is a request structure used in communication between api calls and fixed set of worker goroutines it's using return channel pattern, meaning that after sent the sender locks on that channel to get the response

type Resp ¶

type Resp struct {
	ID     int
	Type   int8
	Commit bool
	Err    error
}

Resp response structure - potential candidate for structure pool as it's almost constant size

type SecretKey ¶ added in v0.6.0

type SecretKey = fr.Element

type Signature ¶ added in v0.6.0

type Signature = bls12381.G2Affine

	VerifySubmitBlockCh       chan Request
	VerifyRegisterValidatorCh chan Request
	VerifyOtherCh             chan Request
	// contains filtered or unexported fields
}

func (rm *VerificationManager) GetVerifyChan(stack uint) chan Request

func (*VerificationManager) RunVerify ¶

func (rm *VerificationManager) RunVerify(num uint)

func (*VerificationManager) VerifyChan ¶
