Functions

func RegisterTxServiceAmino

func RegisterTxServiceAmino(cdc *amino.Codec)

RegisterTxServiceAmino ...

func VerifySignature

func VerifySignature(tx *protobuf.Tx, pubKey secp256k1.PubKeySecp256k1) (bool, error)

Types

type Proof

type Proof struct {
	RootHash cmn.HexBytes
	Data     Tx
	Proof    merkle.SimpleProof
}

Proof represents a Merkle proof of the presence of a transaction in the Merkle tree.

func (Proof) LeafHash

func (p Proof) LeafHash() []byte

LeafHash ...

func (Proof) Validate

func (p Proof) Validate(dataHash []byte) error

Validate verifies the proof. It returns nil if the RootHash matches the dataHash argument, and if the proof is internally consistent. Otherwise, it returns an error.

type Service

type Service interface {
	SetTxs(txs [][]byte)
	GetTxs() [][]byte
	ParseNewTxRequest(uint64, uint64, *txProtoc.TransactionRequest) error // Accepts incoming protoc structured transactions and sets byte-wise tx transaction
	Hash(tx Tx) []byte                                                    // Hash computes the hash of the wire encoded transaction.
	String(tx Tx) string                                                  // String returns the hex-encoded transaction as a string.
	Index(tx Tx) int                                                      // Index returns the index of this transaction in the list, or -1 if not found
	IndexByHash(hash []byte) int                                          // IndexByHash returns the index of this transaction hash in the list, or -1 if not found
	MerkleHash() []byte                                                   // MerkleHash returns the simple Merkle root hash of the transactions.
	Proof(i int) Proof                                                    // Proof returns a simple merkle proof for this node.
	LeafHash(tx Tx) []byte                                                // LeafHash returns the hash of the this proof refers to.
	// Validate verifies the proof. It returns nil if the RootHash matches the dataHash argument,
	// and if the proof is internally consistent. Otherwise, it returns a sensible error.
	Validate(dataHash []byte) error
