Many people have claimed that with AI-assisted bug finding, secure code (and hence trustless anything) will be impossible. I have a much more optimistic take, and AI-assisted formal verification is a major part of the reason why: https://vitalik.eth.limo/general/2026/05/18/fv.html

Sent another 64 ETH to the Animal Welfare Fund. I encourage others to think and act more in support of our non-human cousins too! The extreme suffering we're imposing on them in the billions is not something we talk about often, but it continues to be one of the larger blights on humanity. And I'm getting optimistic that this century we can finally end it. Farming practices are improving, synthetic alternatives are improving. Also, in my recent experience, good old low-tech vegetarian and vegan food has improved massively worldwide over the last ten years; I encourage anyone who has tried it long before and given up to take second look; there are far more healthier and tastier options today than the "pasta and salad" you would often get ten years ago.

This is a good decision. Preferenxe falsification is a big problem in society and we need to see people's honest views. It would be really cool if Farcaster follows it, by implementing ZK likes. Can probably borrow technology from zupoll. https://x.com/wanghaofei/status/1793096366132195529

The Tiergarten in Berlin has become one of my favorite parks and running tracks. Even though the longest (good) loop is only 4.3km, repeating it six times somehow doesn't feel overly repetitive. And today I learned that it has a long and fascinating history, and most of the trees there today are under 80 years old.

Protip: you can come in to Brussels through Amsterdam. Passport control line in AMS is negligible (at least at 5AM, though I'm sure it's not too bad at other times either), and it's only a 2h train ride straight from the AMS airport to Brussels.
