==Test Vectors and Reference Code==

Test vector data for creation of P2MR UTXOs can be found [https://github.com/bitcoin/bips/blob/master/bip-0360/ref-impl/common/tests/data/P2MR_construction.json here].
Test vector data for creation of P2MR UTXOs can be found [https://github.com/bitcoin/bips/blob/master/bip-0360/ref-impl/common/tests/data/p2mr_construction.json here].

These test vectors build off of the test vectors for [[bip-0341.mediawiki|BIP 341]] (Taproot). One important distinction is that the P2MR test vectors do not include keypath spend scenarios.

Also included are test vectors in [https://github.com/bitcoin/bips/tree/master/bip-0360/ref-impl/rust rust implementation] and [https://github.com/bitcoin/bips/tree/master/bip-0360/ref-impl/python python implementation]. One of these tests demonstrates a tapscript that requires a secp256k1 signature to spend the P2MR UTXO (modeled after one of the extremely valuable examples provided by [https://learnmeabitcoin.com/technical/upgrades/taproot/#example-3-script-path-spend-signature this Taproot script path spend example]. Similar to BIP 341 test vectors, all signatures are created with an all-zero (0x0000...0000) [[bip-0340.mediawiki|BIP 340]] auxiliary randomness array.
