I’ve been running experiments on the Bitcoin Inquisition signet, starting with OP_CAT. For this first round I built a witness-locked script: data lives in the witness, the script only verifies the hash — only the holder of part_a/part_b can spend.

One observation: commit transactions show up on both standard signet explorers (mempool.space) and Inquisition nodes, but reveal/spend transactions only appear on Inquisition nodes — standard nodes reject the block entirely. The two networks fork at the first block containing a new-opcode spend. Expected, but worth noting for anyone trying to verify via public explorers.
CSFS, CTV, and INTERNALKEY experiments next.
