P2MR script-path spend of input 0

The node checks this spend by hashing the revealed leaf, walking the Merkle path in the control block up to a root, and requiring that root to equal the output's 32-byte witness program. This page recomputes the same steps.

ML-DSA-44 leaf (OP_CHECKMLDSA44)

OP_CHECKMLDSA44 is an experimental opcode of this test network, not part of BIP-360. Once the rule applies, a template leaf protects only the spending path of its own output.

Block 16973 is at or above the activation height 8600: nodes that enforce the rule checked this signature.

Template: S1: the ML-DSA-44 public key in three pushes, then OP_CHECKMLDSA44
ML-DSA-44 public key: 1312 bytes in 3 pushes (520 + 520 + 272)
Public key fingerprint: 8e71afa71bc838a1… · SHA-256 dbdac6980e01a21f…
Signature chunks: 520, 520, 520, 520, 340 bytes
Tree: ✓ The other leaf can only fail (6a, OP_RETURN): this is the template tree.
