BIP-54 demo stream: Slow block validation on Signet
Wednesday, April 8, 2026In April 2026, Antoine Poinsot and Anthony Towns publicly demonstrated a few slow-to-validate blocks on the Signet test network. These blocks are currently valid, but would be invalid under the BIP-54 Consensus Cleanup rules. I covered this event by streaming the behavior of a Bitcoin Core (affected) and a Bitcoin Inquisition (unaffected) node.
I used a signet setup of my peer-observer tooling and infrastructure to run two nodes. A Bitcoin Core v31.0rc1 release candidate node and a Bitcoin Inquisition v29.2 node. Bitcoin Inquisition is a signet-only fork of Bitcoin Core used to test soft-forks on the Signet test network. Bitcoin Inquisition v29.2 has BIP-54 activated and will reject blocks that, for example, are very slow to validate. The Bitcoin Core node won’t reject these and will validate them.
Running both nodes allows me to show that Bitcoin Core will take a while to validate the blocks and that Bitcoin Inquisition, with BIP-54 active, will reject the blocks. I set up a livestream with a fork-observer instance showing the expected fork between the two nodes. Later a reorg makes sure the slow-to-validate blocks don’t remain in the chain forever.
After an initial test-run documented on BNOC: Slowish blocks on Signet, the event was annouced on Delving Bitcoin: Consensus Cleanup: demo of slow blocks on Signet. It consisted of three identical runs at different times to give everyone a chance to join.

Livestream
I streamed the three runs on YouTube, while Antoine streamed the runs on X. All three runs showed, as expected, that the Bitcoin Core node took a while to validate the blocks, while the Inquisition node rejected them.

Results
After the stream, I posted my debug logs to the Delving thread and extracted some of the validation times. Both nodes ran on the same Hetzner Cloud CX43 host with 8 shared CPU cores of an AMD EPYC-Rome Processor (2019) and 16 GB of RAM. Validation of the slow-to-validate blocks took between 60s and 100s for each block on this host.
