Bitcoin Inquisition 29.2 Brings BIP 54 Consensus Cleanup to Signet Testing
Bitcoin Inquisition 29.2 added experimental support for BIP 54 Consensus Cleanup alongside other proposed consensus changes on signet. The release represented a real testing stage for BIP 54, not activation on Bitcoin mainnet.
On February 7, 2026, Bitcoin Inquisition 29.2 was released as an experimental Bitcoin implementation based on Bitcoin Core 29.3 release-candidate code. Bitcoin Inquisition exists to make proposed consensus changes usable on signet, giving developers and advanced users a place to test features under realistic network conditions without changing Bitcoin mainnet.
The 29.2 release included experimental support for BIP 54, known as Consensus Cleanup, along with previously supported proposals such as ANYPREVOUT, CHECKTEMPLATEVERIFY, OP_CAT, CHECKSIGFROMSTACK, and OP_INTERNALKEY. In Bitcoin Inquisition terminology these proposals can be given “heretical activation” on signet so software and transaction behavior can be exercised before any mainnet consensus decision.
BIP 54 sought to clean up several long-standing edge cases and legacy consensus behaviors. The February release therefore represented a meaningful maturity stage: the proposal was not merely being discussed on a mailing list, but had entered a runnable environment where its behavior could be tested with actual blocks and transactions.
The distinction from activation is important. Nothing in Bitcoin Inquisition 29.2 changed Bitcoin mainnet consensus, and the release should not be described as adoption of BIP 54. Its historical value is narrower: it records the movement of an important consensus-cleanup proposal from design work into a functioning signet experiment.
