yesterday's election was a neon signal to crypto making the bed with fascists is a clear losing, industry killing strategy. if this is what we associate with, the backlash will be extreme, regardless of the technology let us show the world this is a small corrupt minority only

An exciting update from myself and @benediamond ( https://t.co/bKwowXYcMB). We show that the ๐ถ๐ฑ-๐ต๐ฐ-๐ค๐ข๐ฑ๐ข๐ค๐ช๐ต๐บ proximity gaps conjecture is ๐ณ๐ฎ๐น๐๐ฒ. More precisely, given any pair c, d we construct codes whose error grows faster than nแถ / (q โ

For each positive integer $c^*$, we construct an infinite sequence of ReedโSolomon codes $C \subset \mathbb{F}_q^n$, together with ball radii $z$, for which the proportion of $\mathbb{F}_q^n$...

Just published a simpler proof of the RBR soundness of FRI! Work with @0xAlbertG and Benedikt Wagner I also wrote a blog post explaining the high level ideas of the proof. All you need to know is how to colour a graph! Links to paper and blog below 1/3

Privacy is also not just a value (unlike mentioned below). There are many dimensions to it. In the blockchain space, there is sender anonymity, receiver anonymity, relationship anonymity, unlinkability across 2 or more transactions, secrecy of tx value,
Privacy isn't a 'yes or no' feature, it's a 'how much?' feature.

I believe this is a radically underexplored (and high potential) direction and something that I've spent the last year working on https://t.co/NwM1v2XVKq

In defence of FOCIL Note: I genuinely think that more eyes on major EIPs are always a net positive. The more visibility and constructive feedback we get, the more likely we are to ship meaningful, important upgrades for Ethereum. โข FOCIL is about adding multiple proposers that

Excited for the opportunity to bring Ethereum to the world via faster, cheaper, safer, and more decentralized sequencing! ๐๐
Optimism is partnering with Flashbots to bring fast, verifiable sequencing to the Superchain ๐ด Faster confirmations = smoother user experience.

Talks are up [esp for folks in other geographies :)] Also including a link to a geographic decentralisation panel at MEV SBC which I thoroughly enjoyed
A critical part of the crypto mission is building global systems that can stretch across trust boundaries and unlock surplus doing so CR and credible neutrality are key How can we build systems that donโt end up concentrated in one country or region? https://t.co/AWyXGTrbI4?

TIL from @ronrothblum that you can compute all n Lagrange eq(x, i)'s in n + ~\log_2{n} field multiplications (and an inversion) as opposed to 2n๐

I was on a plane with no internet for a few hours and was thinking about cryptography, and then I remembered that Vitalik Buterin once off-handedly mentioned that Poseidon was older and better-studied than BLAKE3, and I got all steamed up about it again and wrote this rant: โคต๏ธ

I partnered with @Data_Always to provide our MEV perspective on the Glamsterdam upgrade. TLDR: While BALs are uncontroversially good for the EL, there is no standout candidate for the CL. Every option has clear pros & cons, some of which surprised us. https://t.co/T33AZU3GKo

A zero-knowledge proof demonstrates that a fact (like that a Sudoku puzzle has a solution) is true while, counterintuitively, revealing nothing else (like what the solution actually is). This...

ePBS ๐ค FOCIL compatibility TL;DR: ePBS and FOCIL are readily compatible, and the clean separation of beacon blocks from execution payloads we get from ePBS helps preserve chain liveness when payloads fail to satisfy IL conditions. ๐
