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.

SLH1 leaf (OP_CHECKSLHDSA128S)

This leaf is SLH1 byte for byte: a 32-byte SLH-DSA-SHA2-128s public key followed by OP_CHECKSLHDSA128S, an experimental opcode of this test network, not part of BIP-360. It runs from height 32000; below that height the byte is OP_SUCCESS241.

Block 33522 is at or above the activation height 32000: nodes that enforce the rule checked this signature.
