Variables ¶
var ErrIndexNotSelected = errors.New("index is not selected")
ErrIndexNotSelected signals that the given index is not selected
var ErrIndexOutOfBounds = errors.New("index is out of bounds")
ErrIndexOutOfBounds signals that the given index is outside expected bounds
var ErrInvalidChainID = errors.New("invalid chain ID")
ErrInvalidChainID signals that an invalid chain ID has been provided
var ErrInvalidReferenceChainID = errors.New("invalid reference Chain ID provided")
ErrInvalidReferenceChainID signals that the provided reference chain ID is not valid
var ErrNilHeaderVersionHandler = errors.New("nil header version handler")
ErrNilHeaderVersionHandler signals that the provided header version handler is nil
var ErrProofHeaderHashMismatch = errors.New("proof header hash mismatch")
ErrProofHeaderHashMismatch signals that the proof header hash does not match the header hash
var ErrProofNotExpected = errors.New("proof not expected")
ErrProofNotExpected signals that the proof is not expected
var ErrProofShardMismatch = errors.New("proof shard mismatch")
ErrProofShardMismatch signals that the proof shard does not match the header shard
Functions ¶
func ComputeConsensusGroup ¶ added in v1.6.14
func ComputeConsensusGroup(header data.HeaderHandler, nodesCoordinator nodesCoordinator.NodesCoordinator) (leader nodesCoordinator.Validator, validatorsGroup []nodesCoordinator.Validator, err error)
ComputeConsensusGroup will compute the consensus group that assembled the provided block
func ComputeSignersPublicKeys ¶ added in v1.6.15
ComputeSignersPublicKeys will extract from the provided consensus group slice only the strings that matched with the bitmap
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 ¶
type ArgsHeaderSigVerifier ¶
type ArgsHeaderSigVerifier struct {
Marshalizer marshal.Marshalizer
Hasher hashing.Hasher
