An internal model at OpenAI has produced a claimed refutation of ETH! Russell Impagliazzo, Mohan Paturi, and I have been asked to help organize an open and independent examination of this claim. 1/4

We’re sharing a solution to the Navier-Stokes Millennium Prize Problem, one of the deepest problems at the frontier of mathematics.
The proof was produced by a group of agents, using an OpenAI next-generation model significantly more capable than GPT-6 Astra.
The problem concerns whether the description of smooth three-dimensional fluid motion modeled by the Navier-Stokes equations can break down. It has remained unresolved for roughly 90 years.

Decentralized thoughts on 2 round BFT in Simplex style
With @ElodinStorm and Ling Ren

Unlike other “off-the-shelf” consensus implementations, consensus::simplex is refreshingly minimal.
It delivers simple agreement over opaque “blobs”. Functions that have historically motivated developers to create forks, like block broadcast, are abstracted as interfaces:

Today, we are excited to share our biggest release yet: consensus::simplex (our first of many upcoming consensus dialects).
consensus::simplex provides BFT agreement via a new, optimistically responsive construction inspired by Simplex Consensus:

For the latest Systems Seminar, @Vervious joins us to present Simplex Consensus.
Simplex has one goal: to be the simplest consensus protocol to prove, implement, and learn. Check it out here:

Discover new consensus protocols with our faculty Prof. Rafael Pass and PhD student Benjamin Chan @Vervious from Cornell. Don't miss out their latest cutting-edge research in #blockchain #consensus!
We have a new consensus protocol for you, called "Simplex Consensus". It's supposed to be fast and easier to understand than everything else out there. Joint work with Rafael Pass. Check it out at eprint.iacr.org/2023/463! 1/3

I know this is top secret information that you don’t normally share, but try opening your heart and tell me which coffee shops are perfect for reading and writing papers (around the world). I will bookmark this thread forever.
I’ll start: Here’s an option for when in Tel Aviv👇

Exciting updates about Streamlet: I'm giving a talk on Streamlet in Berkeley RiseLab tmw! Also stanford 251 cs251.stanford.edu/ is teaching Streamlet! @benediktbuenz . Also @Vervious is speaking about streamlet in AFT next week!

📢A preliminary (read: still very rough) draft my new textbook "Foundations of Distributed Consensus and Blockchains" is available at distributedconsensus.net i'm still updating/rewriting the textbook, pls check back for a later ver. feedback/suggestions are greatly appreciated.

An updated/rewritten version of the streamlet paper is available on eprint! eprint.iacr.org/2020/088.pdf including a crash-fault variant that is a minor tweak of the main protocol. strongly recommended for teaching consensus. Consensus protocols made extremely simple! @Vervious

Currently, the OPT program enables talented graduate students to work in the US for a period after they graduate. Eliminating this program will cause graduate students, with newly minted PhDs, to be forced to leave the US, hurting US competitiveness.
