I just got out of hospital. While I can somewhat function, life will never be the same. There is no cure. This is difficult but I need to share with you all how this happened. Stay indoors. Wear a mask. If you hear anyone say 'gud' or ramble about data privacy, RUN.

Britain is a great country, but unless we reignite growth, we can’t pay for any of our other goals. Was great to talk about this at @lfg_uk Make or Break this week👇
"Whatever you care about, whatever your vision for this country, it will be much easier to achieve it if we make the UK rich again." @matthewclifford at LFG: Make or Break 🚀

I want to use this reminder to highlight a topic that got almost no attention despite all the talk about encrypted compute. Until we get iO, there’s a trade-off between privacy and liveness. Any system that wants private shared state without trusting a single operator or TEE
Regular reminder: A key property of a blockchain is that even a 51% attack *cannot make an invalid block valid*. This means even 51% of validators colluding (or hit by a software bug) cannot steal your assets. However, this property does not carry over if you start trusting

6 years ago, when i first started working in zk, it was a tiny community of cryptographers and i understood nothing plus there were no resources to learn today, i read this and understood 80% of it go find the thing that literally melts your face and try to understand it

You want my credentials? I’m one of the few people alive who has written more books than they’ve read. That’s founder energy right there.

Shameless plug - every zkVM running in prod (except @RiscZero ) runs on ZK tech built by our team at Polygon Zero - including @SuccinctLabs @openvm_org @brevis_zk etc. What’s more Ethereum-aligned than developing the ZK future of the entire protocol? Plonky2 and Plonky3 were
I really appreciate both @sandeepnailwal's personal contributions and @0xPolygon's immensely valuable role in the ethereum ecosystem. To recap: * Polygon hosts @Polymarket, which is probably the single most successful example of a "not just boring finance" app that has actually

Victor Davis Hanson: If You Think Trump Is a ‘King,’ Just Look in the Mirror Who’s more of a “king”: Donald Trump, who ran for election three times, won the popular vote, the Electoral College, and all the swing states in 2024, or Joe Biden, who was appointed by Democratic Party

zkevms are built for scaling. 'zkzkevms' aims for private smart contract interactions. Still very limited though. And waiting for iO as proposed means another 5-10y of very little progress. We can do better. Already now. Private Shared State on coSNARKs & oblivious hashmaps ⬇️

Barry my dude I love you and this is a great research topic, but you’ve gotta be joking if you think this is easy to implement. If you don’t want users to give decryption keys to zkEVM provers then you immediately fall into a complexity spiral that ends up producing something

Yes, the goal of @paradigm and many other VCs is to suck as much value as possible from the Ethereum and broader ecosystem, while also adding value to the ecosystem in the service of maximizing their own gains. Paradigm is particular good at this. Subgoals include progressing the

The rush of ppl building private transactions is great news for the industry, but there is still only one team doing private compute The Private World Computer stands alone on @aztecnetwork
Base is building private transactions. We acquired the Iron Fish team back in Mar 2025 to start working on this. More to share soon.

The new Goku is here and great! Better articulations enable more effective posing than ever! The paintbrush job is on point, too! A must have! For your next S.H.Figuarts, HOBBY GENKI!

Peer-to-peer money needs to resemble real-world, web2 transactions in order to be adopted. Until now, the best privacy blockchain could offer was either anonymity (hiding identity) or confidentiality (obfuscating transactions). Neither of those instills confidence in most people

Noir isn’t a zkDSL anymore. It’s the only programmable cryptography language out there.
Want to build privacy-preserving apps but intimidated by MPC? Good news: if you know Circom or Noir, you can already start. Here’s how we’ve made ZK + MPC usable for devs 🧵👇

Today's been a day and a half... get woken up by PagerDuty at 2AM. The Sepolia Fusaka upgrade has been fun. Have been hunched over my keyboard ever since... 15 hours straight minus a coffee run. Time to touch some grass 🪿🌲 and eat some tacos 🌮

before the Solana foundation donated 500k before the EF stepped up to help Alexey publicly before Paradigm helped Roman Storm when it was still taboo to do it remember who was willing to stand with Roman & Alexey and say that developing privacy on Ethereum was not a crime ✌️
I remember conversations advising me that I was too close to Tornado Cash and that I should flee the US or else risk being arrested as well but I stayed and helped coordinate raising millions of dollars for the Alexey & Roman legal defense fight together, or die alone 🫡

The more I am shipping with Aztec, the more I am knowing that we have something really cool, something really novel, special and groundbreaking!
You can onramp someone on Aztec, with a partial note, with complete privacy! A Partial note allows someone to receive a digital asset on Aztec, without them knowing you are actually on Aztec. The onramp provider will know they paid some address `x` amount on Aztec, but not to

Working on marketing a new technology is weird. Sometimes I feel like Gutenberg’s hype man, and I’m all amped about the printing press coming out. Then I write some articles about how books are going to change everything. Maybe make a diagram about type setting. But
