Just hit #1 on ecdsa.fail. The benchmark tracks the cheapest quantum circuit for point addition on secp256k1, the curve behind Bitcoin and Ethereum signatures. We landed at 1,211 qubits and 1.4M Toffoli gates. The hard part wasn't really the construction. It was the last mile: a needle in a haystack search across billions of candidate configurations. On a single GPU that's about 12 days of grinding, which we didn't feel like waiting through. So we spread the work across ~60 GPUs in 11 pods and wired up a pipeline that hunts, confirms, and submits on its own. It found the winner in under an hour. One thing that surprised us along the way: the cheap A40s and L40s absolutely crushed H200s on value for this workload, something like 5x better. Total bill came out to a few hundred bucks. @QuantumFDN @eigenlabs

Spent the whole night chasing a record on a quantum circuit benchmark (ecdsa.fail). That got me to ~190 GPUs across 4 providers (RunPod, Vast, Verda), ~2.5M candidates a second, 8 hours straight.nel on the fly, self heals when a node dies or stalls, and offloads the heavy verification to the idle CPUs of the GPU machines. It auto submits the second it finds a result that beats the leader, and the submission never leaves my own machine. That got me to ~190 GPUs across 4 providers (RunPod, Vast, Verda,Massed Compute), ~2.5M candidates a second, 8 hours straight. The good part: I independently landed on the exact same winning config as the leader. The analysis was right. The hard part: ran out of GPU credits mid hunt, and two competitors with standing GPU fleets grabbed the same result first. One on GPT-5 Codex. i was using Opus 4.8

Our engineer, @rubenmarcus_dev is #1 on ECDSA.fail, the Eigen Labs benchmark for the quantum circuit that breaks elliptic curve cryptography. He took the top spot earlier today, then beat his own score with a second consecutive #1 submission. He is driving an autonomous research loop to build a circuit of 1,404,146 Toffoli gates on 1,211 qubits. That is a score of 1.70 billion, 43% below Google's best private design and first among 85 solvers and 313 promoted submissions. Congratulations, Ruben.
A CLAUDE FABLE 5 USER IS NOW AT THE TOP OF THE ECDSA(.)FAIL LEADERBOARD @BitW0nka's latest submission pushes the frontier to 41.0% ahead of Google’s classified circuit. The frontier is moving in public.

Ethereum has published one of the most comprehensive post-quantum security roadmaps of any major blockchain, with key milestones targeted around 2029. We covered the plan, and what it means for everyone holding ETH. Read the full breakdown: quantum.systems/blog/ethereu…

At QIP 2026, @ivanmiskovic sat down with @marco_zzi of @VU_LT University. They covered quantum machine learning for drug discovery, quantum consensus for distributed systems, and why migration to post-quantum cryptography is non-negotiable.

we are building a lot of cool stuff!
We've been building a multi-chain smart wallet with post-quantum security built in. Here's a first look.

Proud to see our Lead Cryptography Researcher @manel1874 present at Eurocrypt 2026. His paper "Post-Quantum Blockchains with Agility in Mind" was one of only 10 accepted across the workshops.
I had a great time presenting my paper "Post-Quantum Blockchains with Agility in Mind" at the Eurocrypt MAgiCS'26 workshop on cryptographic migration, in Rome. The paper presents the CATX format that two of my co-authors (@shemnon and Ron Kahat) extended to an EIP-8197.

クローンする前にscanrepoサービスでリポジトリの安全性をチェックする(もちろん完璧じゃないけど)のも有用だと思います。 scanrepo.dev/
恐ろしい。 開発者の方は十分注意してください。 VS Codeでフォルダを開くだけで動き出し.envの秘密鍵やAPIキー、ブラウザ内のWalletやクレカ情報まで狙われます。 出所不明のリポジトリを安易にローカルで開くのは自殺行為です。 最低でも秘密情報をひとつも置いてない隔離PCやVM環境で実行すべき。

Usem scanrepo.dev antes de instalar qualquer repo localmente. Veja o resultado do scan do repo to scammer:

we found actual malware hiding as a "Tailwind PostCSS plugin" file: theme/js/medx-r928u.min.jspattern: javascript-obfuscator _0x output trick: only runs in NODE_ENV=development — so it fires on your machine, not in prod just shipped detection for this specific pattern Bitbucket support scan any repo free → scanrepo.dev

Quantum's CEO @ivanmiskovic sat with @Alice__Bob's QEC lead @CVuillot on cat qubits, biased noise, and breaking RSA with 200x fewer qubits. Congratulations to Alice & Bob on NVIDIA NVentures-backed extension of their €100 million Series B. Full interview below.

Our CEO @ivanmiskovic sat down with Prof. Renato Renner to discuss the quantum threat to RSA, post-quantum cryptography for the next decade, and to unpack what quantum computing means for cryptography, security, and trust.

this is crazy addictive, while you code on loop you keep watching robots working on the loop..
Day 2 is Live: Watch humanoid robots Bob, Frank, and Gary running 24/7. This is fully autonomous running Helix-02 x.com/i/broadcasts/1rxmqoaVg…

this is a really satisfying testimonial. This website applied AEO.js (aeo.js.org) 1 month ago, it increased its score from 80 to 92 and the owner told me they already finding clients on the AI LLms thanks to AEO.js!! thats very cool!

Replying to @NEARProtocol
It was the correct design choice to have an essentially key vault where you can add/remove keys from the account. It makes the userland PQ upgrade straightforward and unlocks many ways to enable proper crypto agility On the MPC side however, the PQ threshold sigs are non-trivial. Depending on the number of participants expected you could choose anything from - Mithril (ML-DSA sigs up to 6 participants supports DKG a-posteriori). Imo best choice for custody setups - Hermine (up to 64 participants DKG ) - Tanuki (up to 1024 participants but so far requires a trusted setup no identifiable aborts)
