Functions

func Prove

func Prove(txid Hash256Digest, merkleRoot Hash256Digest, intermediateNodes []byte, index uint) bool

Prove checks the validity of a merkle proof

func VerifyHash256Merkle

func VerifyHash256Merkle(proof []byte, index uint) bool

VerifyHash256Merkle checks a merkle inclusion proof's validity. Note that `index` is not a reliable indicator of location within a block.

Types

type Hash256Digest

type Hash256Digest = chainhash.Hash

func Hash256

func Hash256(in []byte) Hash256Digest

Hash256 implements bitcoin's hash256 (double sha2)

func Hash256MerkleStep

func Hash256MerkleStep(a []byte, b []byte) Hash256Digest

Hash256MerkleStep concatenates and hashes two inputs for merkle proving

type Merkle

type Merkle struct {
	// contains filtered or unexported fields
}

Merkle is a wrapper around "github.com/btcsuite/btcd/blockchain" merkle tree. Additionally, it provides a method to generate a merkle proof for a given transaction.

func NewMerkle

func NewMerkle(txns []*btcutil.Tx) *Merkle

func (*Merkle) BuildMerkleProof

func (m *Merkle) BuildMerkleProof(txIndex int) ([]byte, uint, error)

BuildMerkleProof builds merkle proof for a given transaction index in block.

type Proof

type Proof struct {
	TxBytes []byte `protobuf:"bytes,1,opt,name=tx_bytes,json=txBytes,proto3" json:"tx_bytes,omitempty"`
	Path    []byte `protobuf:"bytes,2,opt,name=path,proto3" json:"path,omitempty"`
