Instead of watching an hour of Netflix watch this 30 minutes lecture and learn more about bitcoin mining than most people working at top Bitcoin companies learn in their entire careers. https://t.co/VI2kpaEBQl

Our Director @n1ckler on SHRINCS and SHRIMPS at @OPNEXT2026: SHRINCS converts systemic quantum network risk into localized device risk. Localized risk can be managed. SHRIMPS adds a second compact path for backup devices: ~3,000 bytes vs 580 bytes primary, 0.87 TPS vs 0.36 TPS baseline.

The quantum threat to Bitcoin may still be a decade away, but @blksresearch is already working on the solution. Adam Back (@adam3us) joined @FINTECHTVglobal at @consensus2026 Miami to explain how Bitcoin will be ready before quantum becomes a threat. https://t.co/qrRNCZh1vG

> What happened to you? We have been consistent for years. Read "The Blocksize War" chapter 7 Thinking that the main purpose of running a node is to relay transactions is a "large blocker" misconception. While a strong relay network is important, it is nowhere near as important as enforcement of the consensus rules

"Bitcoin has no undo, it's a bearer asset. Bitcoin's reliance on cryptography is another level, because it's bearer and final." @adam3us on why Bitcoin and traditional finance are fundamentally different, and why quantum readiness doesn't need to happen overnight. https://t.co/Cm5n5PHw1n

BITCOIN RAILS #59#: Post-Quantum Bitcoin Signatures (+ their tradeoffs) | with BIP 360 co-author @Ethan_Heilman and @Blockstream Head of Research @n1ckler 🔗 YOUTUBE: https://t.co/d57SQmKZ0J 🌿 SPOTIFY: https://t.co/Iij3xZ1Aw5 According to BIP 360 co-author Ethan Heilman, Bitcoin needs a minimum of two soft forks to become quantum resistant: P2MR (or an output type that can safely execute PQ signatures) + a post-quantum checksig (signature scheme). Ethan and the BIP 360 team (including myself and @cryptoquick) introduced the P2MR part via a BIP 360 update late last year—but the question remains, what’s the most appropriate PQ signature scheme for Bitcoin? They all have substantive tradeoffs, but hash-based signatures seem to be leading technical discourse—likely due to recent optimizations by @n1ckler and the broader @Blockstream research team. It was an honor to sit down with both of these men - arguably the two most influential and productive cryptographers in Bitcoin quantum mitigation right now - for an in-depth review of the leading PQ signature schemes and a temperature check on Bitcoin’s post-quantum planning process. TBH, if you want to skip the noise and jump straight to the signal on quantum, this is the interview to watch. In this episode, we discuss: - What needs to happen at the soft fork, infra, and mitigation levels to fully quantum-harden Bitcoin - Recent updates to BIP 360 + breakdown of the leading hash-based signatures schemes for Bitcoin (SHRINCS + SHRIMPS) - Why we may actually get consensus around a stateful scheme for Bitcoin - Comparisons of hash-based signatures vs Lattice and Isogeny-based schemes - Assessing the risks of both waiting too long and acting too fast (and why quantum is a better threat to be facing than a potential classical attack) This episode of Bitcoin Rails is brought to you by my NEW sponsors: - LayerTwo Labs @LayerTwoLabs — developing research, software, and technologies for scaling Bitcoin via the integration of Drivechains (BIP 300/301) - Hashi on @SuiNetwork — a primitive for executing Bitcoin Defi transactions, without having to trust a federated bridge or other centralized entity - BitBox @BitBoxSwiss — an open-source Bitcoin-only hardware wallet, with smooth UX and no compromises on security.

> After Bitcoin Core 0.14.0 and before Bitcoin Core 29.0, validating a specially-crafted block may cause the node to access previously freed memory. > An attacker capable of mining a block with sufficient proof-of-work could have exploited this to crash victim nodes.

Jonas Nick (@n1ckler) joined a technical panel on the open source stage at Bitcoin 2026 to discuss post-quantum signature schemes for Bitcoin, sharing why @blksresearch has been exploring hash-based signatures as the safer path forward. https://t.co/E7xAMolhRG

If you didn't catch it Friday, we had an incredible chat with legends @adam3us and @macrocrunch that we just had to run again. Adam breaks down where Bitcoin is now, where it's headed, and where he thinks the price is going next. If you missed it the first time, don't worry, I got you! @RoxomTV

Seems that some people are deeply disappointed that the 83 byte OP_Return limit wasn't a consensus rule and they think it ought to have been. Therefore they act as if it was a consensus rule. Very similar to how the larger blockers were deeply disappointed that the 1MB Blocksize limit was a consensus rule and tried to act as if it wasn't, act as if there was no such thing as consensus rules or act as if consensus rules are fuzzy. Maybe the OP_Return relay limit should have been a consensus rule, but it isn't. They need to accept that reality and accept the reality of what consensus rules mean.
