I’ve been wanting to do a “Great Consensus Cleanup” episode for ages now - given that it’s one of the least well understood BIPs out there (IMO) and is looking more and more likely to instigate Bitcoin’s next soft fork activation. Seems about time we break this down on the show.

Thanks to its progenitor @TheBlueMatt for joining me — and grateful to @darosior for his work in reviving this proposal in the form of BIP 54 🙏🙏

Bitcoin’s Next Soft Fork: Quantum or the Great Consensus Cleanup? | MATT CORALLO

Following years of community gridlock post-Taproot, there’s growing confidence among experts that Bitcoin's next soft fork will be a low-controversy effort to address four long-standing consensus-level bugs through the activation of BIP 54, a.k.a. the “Great Consensus Cleanup.”

Originally put forward by today’s guest, Matt Corallo (@TheBlueMatt), and more recently revised by Antoine Poinsot (@darosior), the upgrade addresses the “cruft” of Bitcoin’s design — including edge-case vulnerabilities like certain kinds of poison blocks, time warp attacks, and others.

At the same time, developer resources are rapidly moving towards quantum resistance proposals for Bitcoin — including BIP 360 (co-authored by Hunter Beast, Ethan Heilman, and Head of MARA Foundation Isabel Foxen Duke) and the recently circulated “SHRINCs” signature proposal by the @blksresearch team and collaborators like Heilman (@Ethan_Heilman) and @conduition_io.

This episode of MFTV breaks down the Great Consensus Cleanup and the post-quantum output type debate — shedding light on key challenges of Bitcoin governance along the way.

Most people focus on decentralized template generation when they think of Stratum V2 — but there are arguably even more significant and immediate business benefits for miners making the switch.

I was floored to learn how common man-in-the-middle attacks (explained by @thebluematt in this clip) are, in part because Stratum V1, the longstanding mining communication protocol, has remained unencrypted for well over a decade.

Very proud to see @MARA adopting Stratum V2 and contributing to the Stratum V2 Working Group led by @pavlenex. Thanks to @avg_gary for sharing your expertise here as well!

“BitVM and Ark walk into a bar…”

I don’t know the rest of the joke, but these are definitely the most handsome scaling solutions in Bitcoin 🤷‍♀️

For anyone who wants to skip straight to the quantum portion of my interview with @TheBlueMatt, I thought I'd share this clip that specifically addresses his views on BIP 360 and other proposals for post-quantum Bitcoin output types.

This is a great time to remind folks that BIP 360 — and post-quantum output types in general — will only be *one* piece of a much larger Bitcoin quantum-resistance pie.

After we finalize an output type, we'll also have to settle on an actual post-quantum signature scheme (e.g. that proposed by SHRINCs team @n1ckler @conduition_io @kudinov_mikhail @Ethan_Heilman ), what to do about abandoned coins, recovery schemes, wallet upgrades, and much much more.

Finally home after 3 weeks of marathon-conferencing in Europe. I have to say @LuganoPlanB was a major highlight. One of the most high signal conferences I’ve been to in the most absolutely stunning location. Lugano really is the Bitcoin capital of Europe!

Thanks to @sbaaaam21 and team for all the special touches in top 🫶
