Function: checkMerkleProof

Implement merkle proof per https://tsc.bitcoinassociation.net/standards/merkle-proof-standardised-format/

We extend the current standard by implementing targetType 'height' (binary value 3). This extension avoids the need to maintain a merkleroot or block hash index for all headers, reducing the space required by 50%.

Other extensions are not currently supported.

Supports partial and full binary format as well as hex strings.

External Assumptions:

  1. The raw transaction is in-hand and is either duplicated in the proof or matches the starting hash used to evaluate the merkle tree branch.

Checking the proof verifies these claims:

  1. The merkleRoot determined by the targetType is confirmed to match a block header on the active chain.
  2. Computing a merkleRoot value starting with the transaction hash, using the proof nodes yields a match for the target value.

Implications:

  1. The transaction in-hand is valid and was included in a block on the active chain.
export async function checkMerkleProof(txid: string | Buffer, proof: TscMerkleProofApi | Buffer, chaintracks: ChaintracksClientApi): Promise<BlockHeader> 
Function checkMerkleProof Details

The block header containing the verified merkleRoot

Function: getEnvelopeForTransaction

A transaction envelope is a tree of inputs where all the leaves are proven transactions. The trivial case is a single leaf: the envelope for a proven transaction is the rawTx and its proof.

Each branching level of the tree corresponds to an unmined transaction without a proof, in which case the envelope is:

  • rawTx
  • mapiResponses from transaction processors (optional)
  • inputs object where keys are this transaction's input txids and values are recursive envelope for those txids.

If storage is defined, any previously unseen txids that are required to build the envelope will be added to the proven_txs table, if they can be proven.

The options.maxRecursionDepth can be set to prevent overly deep and large envelopes. Will throw ERR_EXTSVS_ENVELOPE_DEPTH if exceeded.

export async function getEnvelopeForTransaction(services: CwiExternalServices, chain: Chain, txid: string | Buffer, options?: GetEnvelopeOptionsApi): Promise<EnvelopeApi>

  • txid
    • the transaction hash for which an envelope is requested.
