func ComputeTxID(rawTxHex string) (string, error)

ComputeTxID computes the txid from raw transaction hex (display order, handles segwit).

func DecodeTransaction(rawTxHex string) (*wire.MsgTx, error)

DecodeTransaction decodes raw transaction hex into a wire.MsgTx.

func DecodeTxOutProof(txoutproofHex string) (*wire.MsgMerkleBlock, error)

DecodeTxOutProof decodes a txoutproof hex string into a wire.MsgMerkleBlock.

func ExtractOpReturn(rawTxHex string) (string, error)

ExtractOpReturn parses a raw transaction and returns the OP_RETURN data as hex.

func ParseBlockHash(txoutproofHex string) (string, error)

ParseBlockHash decodes a txoutproof hex string and returns the block hash (display order).

type MerkleResult struct {
	Valid        bool
	ComputedRoot *chainhash.Hash
	MatchedTxIDs []*chainhash.Hash
}

MerkleResult holds the result of a partial merkle tree verification.

func VerifyPartialMerkleTree(
	hashes []*chainhash.Hash,
	flagBytes []byte,
	totalTxs uint32,
	expectedRoot *chainhash.Hash,
) MerkleResult

VerifyPartialMerkleTree verifies a Bitcoin BIP 37 partial merkle tree. Takes the hashes and raw flag bytes from wire.MsgMerkleBlock directly.
