[Justin Drake @drakefjustin]

Today I call upon the blockchain industry to calmly begin planning for "bunker mode". My personal recommendation is to set in motion a controlled mass migration of assets to fresh addresses, i.e. addresses whose pubkeys remain hidden behind a hash.

Holders, starting with large and sophisticated ones, should consider moving the bulk of their funds to addresses that have never signed a transaction. And when they do sign one, they should also move remaining funds to a new address (possibly generated from the same seed phrase).

Don't rush. While I believe there is cause for action a rushed migration would do more harm than good. Don't panic either. Moving assets to protected addresses is a simple, preventative step which does not require new cryptography or new wallets.

IMO it is now reasonable to brace for the possibility that ECDSA breaks before qday, in the worst case in months not years. By "break" I mean fast private key recovery (e.g. in one week) on available hardware (e.g. a large GPU cluster).

Recent days have been humbling for human mathematical intuition. Long-held, unquestioned hypotheses have fallen. This includes the n log(n) bound for integer multiplication and the 3SUM conjecture. In hindsight, May's unexpected disproof of the Erdős unit distance conjecture was our warning shot.

Yesterday's OpenAI drop made it clear that mathematical superintelligence is upon us. They say there are weeks where decades happen. We are about to live through weeks where centuries of mathematical progress happen. Could our magic 64-byte ECDSA signatures be too good to be true? Was it just security through obscurity all this time?

Elliptic curves feel especially vulnerable to superintelligence. Curves carry rich structure, with room for fancy tricks like Schoof, Frobenius, pairings. (By contrast, hashes are designed to minimise algebraic structure.)

Separately, as Ewin Tang can attest, an efficient quantum algorithm sometimes foreshadows an efficient classical one. We should be open to the possibility of a classical counterpart to Shor that breaks elliptic curves and RSA at once.

Also noteworthy is the striking under-representation of cryptographic breakthroughs among the 722 mathematical results OpenAI published. I've witnessed first-hand the US government censoring academic quantum cryptanalysis results. Backroom interventionism is my base case.

I urge large, sophisticated actors to lead by example. Project11's "risq list" (bitcoin-risq-list.projecteleven[.]com) is a great tracker of exposed BTC pubkeys. Binance, Bitbank, Robinhood, Bitfinex, and Tether have an opportunity to harden their cold storage. Next month I'll address institutions in London in a live Q&A (forum.ethereuminstitutional[.]org/london-2026).

Again, please do not rush. Wallets holding under 50 BTC enjoy partial cover from "Satoshi's shield", i.e. his 20K exposed addresses that hold 50 BTC each. Load-bearing signers like oracles and L2 security councils should consider rotating ECDSA pubkeys with every signed message and/or multi-signing with a hash-based schemes like SPHINCS.

Exiting bunker mode safely will require post-AI cryptography. My inclination is to go all-in on hash-based cryptography and avoid structured mathematical assumptions entirely, whether from curves, lattices, or isogenies. A single battle-tested hash (e.g. from the SHA or BLAKE families) yields plausible post-AI security.

The Ethereum roadmap on strawmap[.]org fully embraces hash-based cryptography with end-to-end formal verification as a response to the quantum threat. Those timelines must now be revisited and accelerated in light of mathematical superintelligence. I'll be pushing for maximum defensive acceleration.

Israeli strikes have killed at least 39 people, wiping out entire families, in a single day of attacks across Lebanon during a so-called ‘ceasefire.’ Here are some of their stories.

[Tamer Nahed @Tamer_Alnoaizy]

One of the most horrific scenes in human history has been leaked.

When Israel forced thousands in Gaza to run after a loaf of bread under gunfire.

A moment the world should never forget.

[Void.hl @voidHL]

The points meta is broken.

we farm for months. wait on a TGE.
get rugged by allocations & repeat.

@tradewithonyx built UPI to fix this.
every week, their users auction their points for a real share of the fee pool funded 100% by trading activity on the platform.
the winners get paid out.

the bid points get burned and remaining points get scarcer.

this is what a points program is supposed to look like.

[Onyx @Onyx_terminal]

Gearing up for public launch.

Gearing up for HIP-4.

Gearing up to change the game.

🇮🇱🇵🇸Holy shit, Haaretz published a list of atrocities Israeli soldiers did and saw in Gaza, and the details are stomach churning:

•⁠ ⁠Soldiers pissing on a bound, blindfolded detainee while laughing and joking about October 7
•⁠ ⁠Interrogators torturing detainees by tying cable ties around their genitals
•⁠ ⁠An officer executing an unarmed Palestinian who had surrendered with hands up, then covering it up as a “terrorist killed”
•⁠ ⁠Widespread excitement in units over “special means” used to kill people in tunnels, while one soldier said it reminded him of the Holocaust
•⁠ ⁠A tank gunning down five Palestinians crossing a line (four killed), followed by a D9 bulldozer burying the bodies in sand
•⁠ ⁠Soldiers opening fire on unarmed civilians, including an old man and three teenage boys who turned out to be completely unarmed
•⁠ ⁠Looting Palestinian homes, burning photos, and urinating on personal belongings for fun

The impact back home has been brutal.

Soldiers are throwing out mirrors because they can’t look at themselves.

Others are breaking down crying in public. Many are struggling with suicidal thoughts, shame, and nightmares.

These soldiers will carry this for decades.

Heavy, painful reading.

Every Defi protocol should have:
1. Circuit breakers for deposit and withdrawals, and possibly other internal operations as well
2. Timelocks for any change
3. Security councils that can shut down protocols immediately

We don't need insurance, we need to do start doing the ffcking basics correctly. It's too early for this space to drive without any training wheels.

I beg you, sacrifice a tiny bit of UX to gain a lot of peace of mind. The worst possible UX is losing your user's money.

I don't think people understand the gravity of the situation as the UN is preparing for possible nuclear weapon use in Iran.

This is a picture of Tehran. For you uneducated, untraveled, never-served, warhawks licking your chops at the thought of bombing it. It's not some low population desert. There are families, children, family pets. Regular working class people with dreams. You're sick to want war.

Tehran is a city of nearly 10,000,000 people. Imagine nuking Washington, Berlin, Paris, London, or beyond, bombed with nuclear weapons.

I gave up my diplomatic career to leak this information. I suspended my duties so as not to be part of or a witness to this crime against humanity, in an attempt to prevent a nuclear winter before it is too late.

Yesterday, nearly ten million people protested “No Kings” in the United States. The possibility of the use of nuclear weapons must be taken very seriously. It's dangerous. Act now. Spread this message worldwide. Take the streets. Protest for our humanity and future. Only the people can stop it. History will remember us.

الحروب التي تستهدف المدنيين، من أي طرف كان، مرفوضة ومدانة بشدة، ويجب أن تُحاسَب. ماذا يحقق استهداف الأبرياء غير خلق المزيد من الكراهية في عالمٍ أصلاً مثقل بالعنف والقهر؟

أتابع ما يحدث في #لبنان، ويختلجني، كما كل إنسان لديه إحساس، غضبٌ وحزن. فما نشاهده اليوم من استهداف للصحافيين، مهما كان انتماؤهم، مؤلم وغير مقبول، ويطرح أسئلة لا يمكن تجاهلها.

أنا ضد #حزب_الله، وضد أي جهة تجرّ لبنان إلى مواجهات وصراعات بسبب حسابات أو ولاءات خارجية. لبنان يجب أن يكون قراره بيد أبنائه، ومصلحته فوق كل اعتبار. كما أننا لسنا مع أي طرف يجرّ المنطقة إلى صراعات، أو يضع مصالحه فوق مصلحة أوطاننا وشعوبنا.

لكن ما تقوم به #إسرائيل جرم لا يمكن السكوت عنه. هناك مبادئ لا يمكن التنازل عنها، وخطوط لا يجوز تجاوزها. استهداف المدنيين؛ صحافيين، أطباء، وعمال إغاثة، جريمة لا يمكن تبريرها تحت أي ظرف. هؤلاء يمارسون عملهم، ينقلون الحقيقة، ويخدمون الناس، ولا يجوز أن يكونوا أهدافاً.

ما الذي يُحقَّق من استهداف أشخاص يرتدون بوضوح سترات تُعرّفهم كصحافة، وهم يفترض أن يكونوا محميين بموجب الأعراف والقوانين الدولية؟ ومتى أصبح انتهاك هذه الأعراف مقبولاً، ويُبرَّر أو يُتجاهل، فقط بحسب هوية الطرف الذي ينتهكها؟

الإنسان يجب أن يبقى فوق كل الحسابات السياسية والعسكرية. وما نشهده اليوم يذكّرنا بأن كرامة الإنسان أصبحت، في كثير من الأحيان، آخر ما يُؤخذ في الاعتبار.

ألم يكفِ هذه الحكومة الإسرائيلية ما ارتكبته في غزة؟ وإلى متى تبقى دون محاسبة على جرائمها؟

نحن نريد الاستقرار، ونريد السلام، ونرفض أن تتحول منطقتنا إلى ساحة مفتوحة يدفع ثمنها الأبرياء. ما يحدث يجب أن يتوقف، لأن الدم لا يمكن أن يكون وسيلة لإيصال أي رسالة، وليس ثمناً مقبولاً لتحقيق السلام.
