Bitcoin Inquisition 29.4 is now available from

This includes support for the following proposed consensus changes:

BIP 118 SIGHASH_ANYPREVOUT (PR#84)
BIP 119 OP_CHECKTEMPLATEVERIFY (PR#85)
BIN-24-1 aka BIP 347 OP_CAT (PR#83)
BIN-24-3 aka BIP 348 OP_CHECKSIGFROMSTACK (PR#87)
BIN-24-4 aka BIP 349 OP_INTERNALKEY (PR#86)
BIP 54 Consensus Cleanup (PR#90, PR#99)
BIP 446 TEMPLATEHASH (PR#100)

The first two of these have been active on the default signet since block 106704 (2022-09-06), the third since block 193536 (2024-04-30), and the fourth and fifth have been active since block 272592 (2025-10-06), and the sixth has been active since block 291168 (2026-02-12).

The seventh has been triggered as of block 314315 and should be active as of block 314928 (around 2026-07-26).

Note that transactions making use of these new features will not be relayed by nodes that don’t support these features, so if you’d like your transaction to get to a miner, you’ll need to peer with other inquisition nodes. An easy way to do this is to specify addnode=inquisition.bitcoin-signet.net. By default, Bitcoin Inquisition nodes will advertise themselves via the subversion string, which can be viewed with bitcoin-cli -netinfo 3. See the 23.0 announcement for more details.
