@CryptoOrrDun But a paper can not have non-attributed facts. This can be enforced easily using AI. And attributions would be easy to verify if bibliographic references would be enhanced (again, easy to do now).
@CryptoOrrDun If you want to forbid something it is more than just okay with being called XXX. There must be deep reasons not to just dislike but prohibit a certain way of doing research.
@CryptoOrrDun This further convinces me that AI-assisted papers should come with a package of additional materials that simplify third party verification : prompt history, snippets from cited papers, AI-friendly latex source, etc.
Quantum computers (if and when they do in fact get powerful enough) would break Ethereum’s BLS signatures, so what can be done now to mitigate?
For the second instalment of the @leanEthereum miniseries. Nico sat down with Benedikt Wagner and Dmitry Khovratovich (@Khovr) from the @ethereumfndn
We unpack leanSig, a hash-based multi-signature scheme designed to replace BLS in a post-quantum world.

Скоро будет 24 февраля — 4 года полномасштабного вторжения в Украину.
Я считаю, что лучше оставить тот день для полной поддержки украинцев. Украине нужно много помощи — чтобы продолжать защищаться и чтобы минимизировать человеческие страдания от атак на жилые дома, энергосистему и т. д. Сегодня выскажу своё мнение с ��очки зрения будущего России.
Я смотрю на эту ситуацию частично с внутренней и частично с внешней перспективы. Я родился в России, моя семья вся русская, но вырос я в Канаде. Политическую ситуацию я всё время наблюдал. В 2017 году даже послал Навальному один биткоин, но сильно вовлечён не был. Я слежу за ситуацией через интернет, как все. И у меня есть свои политические инстинкты после 15 лет в крипте и всякой борьбы в Твиттере (Иксе?). У каждого есть право меня слушать или не слушать — как хотите.
Здесь напишу две части:
1. Почему я поддерживаю Украину и говорю, что эта война — преступная агрессия, а не «сложная ситуация, где обе стороны вели себя грязно», как говорят некоторые?
2. Про будущее: сегодняшний «тупик», идея «мира с народом России», и на основе каких идей может быть создано более положительное будущее России, и правильная роль идей «децентрализации», «цифровой демократии» и.т.д.
Ethereum Foundation is releasing detailed requirements for the zkVM architecture whitepaper -- a document to be delivered over three milestones.
Modern zkVMs aren't monolithic circuits. They are composed of many moving parts: segmentation, buses, memory, recursion. Each component may be sound on its own, but system-level security depends on how they fit together.
The whitepaper should cover not only the architecture details but also the security argument behind the recursive proof structure. We expect the final versions to be ready in December 2026 along with the zkVM proofs being <300 KB long at the 128-bit provable security level.

Today marks an inflection in the Ethereum Foundation's long-term quantum strategy.
We've formed a new Post Quantum (PQ) team, led by the brilliant Thomas Coratger (@tcoratger). Joining him is Emile, one of the world-class talents behind leanVM. leanVM is the cryptographic cornerstone of our entire post-quantum strategy.
After years of quiet R&D, EF management has officially declared PQ security a top strategic priority. Our journey began in 2019, with the "Eth3.0 Quantum Security" presentation at StarkWare Sessions. Since 2024, PQ has been central to the @leanEthereum vision. The pace of PQ engineering breakthroughs since then has been nothing short of phenomenal.
It's now 2026, timelines are accelerating. Time to go full PQ:
→ PQ ACD: Antonio Sanso (@asanso) kicks off a bi-weekly All Core Devs PQ transactions breakout call next month. These sessions focus on user-facing security, covering dedicated precompiles, account abstraction, and longer-term transaction signature aggregation with leanVM.
→ PQ foundations: Today we are announcing a $1M Poseidon Prize to harden the Poseidon hash function. We are betting big on hash-based cryptography to enjoy the strongest and leanest cryptographic foundations. Check out our other $1M PQ initiative, the Proximity Prize.
→ PQ devnets: Multi-client PQ consensus devnets are live! Shoutout to pioneers @zeamETH, @ReamLabs, @PierTwo_com, @geanclient, @ethlambda_lean, as well as established consensus teams Lighthouse, Grandine, and soon Prysm. This incredible teamwork is coordinated by @corcoranwill via weekly PQ interop calls.
→ PQ workshops: Building on last year's PQ workshop in Cambridge (see photo), the EF is hosting another 3-day PQ event in October. Top experts from around the world will convene. In addition, a PQ day is set for March 29 in Cannes just ahead of EthCC.
→ PQ FV and AI: Last week Alex Hicks (@alexanderlhicks) ran a specialised maths AI for 8 hours, at a $200 cost. It one-shotted a formal proof one of the hardest lemmas in the foundations of hash-based snarks. Mind-blowing. Applied cryptography will never be the same.
→ PQ roadmap: A comprehensive breakdown of the EF's proposed PQ strategy will be shared soon™ on pq[.]ethereum[.]org. The roadmap targets a full transition in coming years with zero loss of funds and zero downtime. Stay tuned :)
→ PQ education: The ZKPodcast (@zeroknowledgefm) is producing a 6-part video series on Ethereum's PQ strategy. EF Enterprise Acceleration is also preparing material for enterprises and nation-states. Finally, Ethereum is now represented on the PQ advisory board that Coinbase announced yesterday.
Believe in something. Believe in PQ security.
zkEVMs crushed the 2025 boss: real-time proving ✅
2026 boss: 128-bit provable security👾
New blog post on the next level for Ethereum zkEVMs: three milestones, paving the path to mainnet-grade L1 zkEVMs.
https://t.co/mueR1JWW6c
Game on.
Craaazy 365 days of @leanEthereum progress. Cheers to the builders. Cheers to the dreamers. Cheers to anti-fragility, too :)
Devcon, Bangkok — Nov 12, 2024. The suspense is real. The room overflows; hundreds can't get in. An "announcement of an announcement" had sparked wild speculation about my "most ambitious initiative".
Who knew the beam chain vision would evolve into lean Ethereum? Next-level ambition, seeping into all layers of L1. Snarks for consensus and execution. Fort mode and beast mode.
What's new? zkEVMs. Real-time proving. Full validation in a tab, on a phone. Let's pump L1 gas with the exponential snark curve. Starting in months, not years. To me it all points to 10K TPS, the gigagas frontier.
Dream bigger dreams for L1. Believe in something.
