Introducing Zinc , where we tackle the problem of arithmetizing and proving computations unfriendly to finite fields. Examples: classic hashes, hash signature, lattice ops., etc. We prove 7 SHA-256 compressions followed by the ECDSA MSM with:

I published a blog post on how to design a more efficient lattice-based folding scheme based on LatticeFold and SNARKs-inspired tricks. osdnk.me/blog/l2-folding-sch… I relied on the work of @Charles_Chen533, @danboneh, @russell_wf_lai ,@KhanhCrypto & myself (& authors w/o x account)

The journey of startup no. 1 has come to an end. (Sadly, it's not because we have been acquired 😅) Learned a lot of new things, about tech and also about people. Maybe in the future I will try once again, with some other ideas I have in my head :3

Just wrote a post about the approach I used to build react-simple-code-editor. It's a very lightweight editor that we use on snack.expo.dev embeds. satya164.page/posts/how-to-w…

PSA: @Google is quietly killing 3rd party appointment booking services like @Calendly in favor of their own newly launched competitor... And of course this "spam prevention" measure doesn't apply to meetings booked through their own new competitive software, which naturally doesn't support any video meetings options but Meet... 🙄 What changed: Google recently auto-opt-in'd most user's to default to NOT show 3rd party invites in calendar UNLESS the booker has previously emailed the host (defeats the point of booking software) or they explicitly accept the invite in email (massively more friction). It's causing major issues for us @GrainHQ where users book time and assume all is well, but accidentally miss meetings b/c it never appeared on their calendar. It still shows as normal on the booking owner's end... These moves are so blatantly anti-competitive and anti-consumer... all under the guise of "spam prevention"... which they could easily manage for google accounts using 3rd party booking software. Any chance @FTC / @TheJusticeDept gets involved to protect consumers? twitter.com/rachel_l_woods/s…
PSA unrelated to AI After some digging - looks like Google might have auto-opted in people to this new setting that hides calendar invites from unknown senders Supposedly to prevent calendar spam But has now caused me to miss 2 meetings with no idea that they were scheduled

Very proud to be part of this story and to work on the unique intersection of cryptography, blockchain, and mobile/front-end engineering. I deeply believe that MPC and AA will be the two wings elevating EVM chains to the top.

Jak to jest możliwe, że można tutaj legalnie pisać takie rzeczy pod informacją o czyimś samobójstwie?

Morning in Ukraine starts with an air raid alarm for the entire country because of the 60 russian missiles in our air space flying to destroy our electricity infrastructure to make sure we all freeze to death this winter. They're incapable of anything, but pure terrorism.

Maybe I’m a bit dummy, but why anyone talks about Kraken in the context of FTX crisis?

New theory: As more and more L1s role out, EVM compatibility will become: A) less important B) a negative signal Why such a radical change of opinion? When I previously thought EVM compatibility was critical for a blockchain success? A mini thread-
