Following up on @instagibbs’s January update, two related LN-Symmetry experiments on bitcoin-inquisition signet that may complement that direction:
-
APO+CTV eltoo (3-round Alice/Bob/Carol scenario): Eltoo State Chain on Signet: Three Rounds, Six Transactions (APO + CTV)
-
CSFS+CTV eltoo ‚ same 3-round scenario, with a key-rebinding ladder. In two transactions. Eltoo State Chain on Signet Again: Three Rounds, Two Transactions (CSFS + CTV, with rekey and ladder, no CAT) Spend TxID: b96324dac3e7…8382de (full TxID in the post)
The CSFS+CTV variant lands close to the TEMPLATEHASH+CSFS migration branch in spirit‚ using the post-Taproot opcode set that Inquisition already activated, with on-chain TxIDs as the validation point. The constructions are implemented as standalone Python scripts against the inquisition bitcoind RPC, so they’re straightforward to re-run on the LNHANCE signet (where CTV and CSFS are also active).
Happy to discuss any of the construction details, especially around the rebinding ladder.
