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.

At MARA Foundation, we are privileged to contribute to the Stratum V2 Working Group 💪

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!

Veteran Bitcoin developer @TheBlueMatt shares his case for a "Pay-to-Taproot-V2" output type for post-quantum signatures—in lieu of BIP 360's proposed "Pay-to-Merkle-Root" output type.

More detail on BIP 360's competing proposals in new MFTV interview below.

"A lot of Bitcoin developers have gotten involved recently enough that they haven't been involved in the process of doing a soft fork and maybe don't feel comfortable with it"

@TheBlueMatt shares why developers may be more conservative about soft forks now than they were 8-10 years ago.

“There’s a laundry list of things we know of that we really need to clean up,” Matt Corallo (@TheBlueMatt) said. “All of these issues are real concerns that could impact Bitcoin negatively, but they’re not like, ‘Oh, the sky is falling.’”

The developer behind the Great Consensus Cleanup believes BIP 54 will be the network’s next soft fork, which has been revised by Antoine Poinsot (@darosior).
