Functions

func NewHeaderIntegrityVerifier added in v1.0.117

func NewHeaderIntegrityVerifier(
	referenceChainID []byte,
	versionsByEpochs []config.VersionByEpochs,
	defaultVersion string,
	versionCache storage.Cacher,
) (*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
	NodesCoordinator        sharding.NodesCoordinator
	MultiSigVerifier        crypto.MultiSigVerifier
	SingleSigVerifier       crypto.SingleSigner
	KeyGen                  crypto.KeyGenerator
	FallbackHeaderValidator process.FallbackHeaderValidator
}

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
