Variables

var ErrNotEnoughSignatures = errors.New("not enough signatures in block")

ErrNotEnoughSignatures signals that a block is not signed by at least the minimum number of validators from the consensus group

var ErrWrongSizeBitmap = errors.New("wrong size bitmap has been provided")

ErrWrongSizeBitmap signals that the provided bitmap's length is bigger than the one that was required

Types

type ArgsHeaderSigVerifier

type ArgsHeaderSigVerifier struct {
	Marshalizer       marshal.Marshalizer
	Hasher            hashing.Hasher
	NodesCoordinator  sharding.NodesCoordinator
	MultiSigVerifier  crypto.MultiSigVerifier
	SingleSigVerifier crypto.SingleSigner
	KeyGen            crypto.KeyGenerator
}

ArgsHeaderSigVerifier is used to store all components that are needed to create a new HeaderSigVerifier

type HeaderSigVerifier

type HeaderSigVerifier struct {
	// contains filtered or unexported fields
}

HeaderSigVerifier is component used to check if a header is valid

func NewHeaderSigVerifier

func NewHeaderSigVerifier(arguments *ArgsHeaderSigVerifier) (*HeaderSigVerifier, error)

NewHeaderSigVerifier will create a new instance of HeaderSigVerifier

func (*HeaderSigVerifier) IsInterfaceNil

func (hsv *HeaderSigVerifier) IsInterfaceNil() bool

IsInterfaceNil will check if interface is nil

func (*HeaderSigVerifier) VerifyRandSeed

func (hsv *HeaderSigVerifier) VerifyRandSeed(header data.HeaderHandler) error

VerifyRandSeed will check if rand seed is correct

func (*HeaderSigVerifier) VerifyRandSeedAndLeaderSignature

func (hsv *HeaderSigVerifier) VerifyRandSeedAndLeaderSignature(header data.HeaderHandler) error

VerifyRandSeedAndLeaderSignature will check if rand seed and leader signature is correct

func (*HeaderSigVerifier) VerifySignature

func (hsv *HeaderSigVerifier) VerifySignature(header data.HeaderHandler) error

VerifySignature will check if signature is correct
