var ErrInvalidChainID = errors.New("invalid chain ID")

ErrInvalidChainID signals that an invalid chain ID has been provided

View Source
var ErrInvalidReferenceChainID = errors.New("invalid reference Chain ID provided")

ErrInvalidReferenceChainID signals that the provided reference chain ID is not valid

View Source
var ErrNilHeaderVersionHandler = errors.New("nil header version handler")

ErrNilHeaderVersionHandler signals that the provided header version handler is nil

View Source
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

Functions

func NewHeaderIntegrityVerifier

func NewHeaderIntegrityVerifier(
	referenceChainID []byte,
	headerVersionHandler factory.HeaderVersionHandler,
) (*headerIntegrityVerifier, error)

NewHeaderIntegrityVerifier returns a new instance of a structure capable of verifying the integrity of a provided header

Types
