IHashCommittedP2WSH

Overview

The IHashCommittedP2WSH interface represents a P2WSH address with hash commitments for the CHCT (Censorship-Resistant Hash Committed Transaction) system. It includes the data chunk hashes, the actual data chunks for later reveal, the chunk starting index, and the P2WSH script public key.

The full source code is available on GitHub at IConsolidatedTransactionParameters.ts.

Interface

IHashCommittedP2WSH

Signature

interface IHashCommittedP2WSH extends IP2WSHAddress {
    readonly dataHashes: Uint8Array[];
    readonly dataChunks: Uint8Array[];
    readonly chunkStartIndex: number;
    readonly scriptPubKey: Uint8Array;
}

Description

The IHashCommittedP2WSH interface extends P2WSH address with hash commitments for CHCT system.
Each output commits to multiple data chunk hashes (up to 98 chunks per output).

Witness script structure:
OP_HASH160 <hash_N> OP_EQUALVERIFY ... OP_HASH160 <hash_1> OP_EQUALVERIFY <pubkey> OP_CHECKSIG

Witness stack when spending:
[signature, data_1, data_2, ..., data_N, witnessScript]

Parameters

Name	Type	Required	Description
dataHashes	Uint8Array[]	Yes	The HASH160 values of all data chunks this output commits to (in order).
dataChunks	Uint8Array[]	Yes	The actual data chunks (stored for later reveal, in order).
chunkStartIndex	number	Yes	The starting index of this output's chunks in the overall data sequence.
scriptPubKey	Uint8Array	Yes	The P2WSH scriptPubKey (OP_0 <32-byte-hash>).
