Types

type Block

type Block struct {
	SignedBlockHeader
	ReadQueries  []*types.Ack
	WriteQueries []*types.Ack
}

Block defines a block including a signed block header and its query list.

func (*Block) Sign

func (b *Block) Sign(signer *asymmetric.PrivateKey) (err error)

Sign signs the block.

func (*Block) Verify

func (b *Block) Verify() error

Verify verifies the block.

type BlockHeader

type BlockHeader struct {
	Version     int32
	Producer    proto.NodeID
	GenesisHash hash.Hash
	ParentHash  hash.Hash
	MerkleRoot  hash.Hash
	Timestamp   time.Time
}

BlockHeader defines a block header.

type DefaultHashSignVerifierImpl

type DefaultHashSignVerifierImpl struct {
	DataHash  hash.Hash
	Signee    *asymmetric.PublicKey
	Signature *asymmetric.Signature
}

DefaultHashSignVerifierImpl defines a default implementation of hashSignVerifier.

func (*DefaultHashSignVerifierImpl) Hash

func (i *DefaultHashSignVerifierImpl) Hash() hash.Hash

Hash implements hashSignVerifier.Hash.

func (*DefaultHashSignVerifierImpl) Sign

func (i *DefaultHashSignVerifierImpl) Sign(
	obj marshalHasher, signer *asymmetric.PrivateKey) (err error,
)

Sign implements hashSignVerifier.Sign.

func (*DefaultHashSignVerifierImpl) Verify

func (i *DefaultHashSignVerifierImpl) Verify(obj marshalHasher) (err error)

Verify implements hashSignVerifier.Verify.

type SignedBlockHeader

type SignedBlockHeader struct {
	BlockHeader
	DefaultHashSignVerifierImpl
}

SignedBlockHeader defines a block along with its hasher, signer and verifier.

func (*SignedBlockHeader) Sign

func (h *SignedBlockHeader) Sign(signer *asymmetric.PrivateKey) error

Sign signs the block header.

func (*SignedBlockHeader) Verify

func (h *SignedBlockHeader) Verify() error

Verify verifies the block header.
