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.

Tripwired leaf (leaf version 0xe0)

M3 is an experimental rule of this test network, not part of BIP-360. From height 30000, nodes run leaves of version 0xe0 as tapscript; once the drill tripwire is spent, from the next block on, elliptic-curve signature checks in such leaves fail.

This page marks only the leaf this spend took. The output's other leaves stay hidden in the spend, so the page says nothing about whether another path could spend the output.

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 40573 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: 4ecdfdf72819ca88… · SHA-256 7e3e01f6857f5200…
Signature chunks: 520, 520, 520, 520, 340 bytes
Tree: ✗ This is not the template tree (two leaves at depth one, the other 6a OP_RETURN): another leaf may spend this output without an ML-DSA-44 signature.
