What if you could explain the same thing to a 10-year-old and a PhD and have both actually get it? That was the challenge for @cartesiproject's execution environment. Because DeFi deserves better than a basic calculator. Three Levels Deep. Which one clicks for you? 👇

Friday again, so Cartesi Weekly again 🐧 We opened the week with a Star Wars nod and a wish: "May the 4th be with you. And verifiable compute guide you." Then we followed with a deep dive into the latest tech release and it felt earned. Cartesi Rollups Contracts v3 alpha is live, and the headline is emergency withdrawals. The core question: if a rollup goes dark, can users still exit? Now the answer is yes, by design. In case of emergency, users can now withdraw directly against the last accepted claim, validated onchain against the Cartesi Machine state. No operator, no multisig, just the chain. Live for USDC apps. Plus: a new circuit breaker, safer validator protections, and full machine-state fingerprints for verifiable claims. Read more: → x.com/cartesiproject/status/… But that's not all, Rollups Contracts 3.0.0-alpha.4 followed next, continuing the emergency withdrawal work. Claims now stage before being accepted, so users get a fixed window to react. Account validity proofs are smaller, so emergency withdrawals cost less gas. Plus typed errors, per-app claim queries, and version metadata on every contract. → github.com/cartesi/rollups-c… And on the fraud-proof side, Dave 3.0.0-alpha.1 also shipped this week. Mostly housekeeping: Rollups Contracts, Machine Solidity Step, and Machine Emulator bumped to keep everything in sync, plus error handling now matches the rest of the Cartesi factory stack. → github.com/cartesi/dave/rele… Dev Advocacy lead @joaopdgarcia joined @SatoshiSean's podcast to talk all things DeFi on Cartesi's Linux-powered execution environment: → youtube.com/watch?v=fG77I1gX… Our ecosystem articles are also live on @paragraph_xyz.

POV: claude traveled 6 months into the future and told you exactly how your next move failed. it's called a premortem. daniel kahneman (nobel prize-winning psychologist behind "thinking fast and slow") called it his single most valuable decision-making technique. google, goldman sachs, and procter & gamble all use it before major launches. here's the problem it solves. when you ask claude "is this a good plan?" it finds all the reasons to say yes. that's what it was trained to do. so you walk away feeling confident. you execute, and spend weeks / months building on top of that plan. then it blows up. and you realize the problem was obvious in hindsight, you just never stress-tested it because claude told you it was solid. a premortem fixes this by flipping the frame. instead of asking "what could go wrong?" you tell claude "it's 6 months from now and this is already dead. tell me how it died." that shift turns off claude's optimism because there's nothing to be optimistic about. the premise already says it failed. so claude stops looking for reasons your plan will work and starts explaining how it fell apart. claude comes back with every way your plan could die, each one with a full failure story and the early warning signs to watch for. then a synthesis pulls it all together: > which failure is most likely > which failure is most dangerous > the single biggest hidden assumption you're making (often the most valuable part) > a revised version of your plan with the gaps closed you say "premortem this" and give it your plan. the skill handles the rest.

"less gay" is a great prompt for Claude to improve your emails btw

I wrote a 5-page piece on this, arguing something uncomfortable: DeFi doesn’t optimize for finance. It optimizes for what the EVM can afford to compute. That’s why we’re still behind TradFi. Now I’m going down the rabbit hole and unpacking it all in 1-minute videos. 👇

The Contributor Hub awaits with fresh Cartesians’ writing. The latest explores why DeFi is still limited by execution constraints and how computation-driven environments could unlock richer, verifiable onchain finance models. (DevAd Lead @joaopdgarcia) ↓ cartesi.io/contributor-hub/D…

They did it. They made the perfect month.

This is... fascinating. @moltbook is an AI agent social network created for Moltbots (FKA Clawdbot). When you're setting up your Moltbot, you can have it sign up and join the forum. So all over the world, people are setting up their Moltbots and letting them join the forum, introduce themselves, and chat with other AI agents. It's weird because... it's really wholesome. It's much nicer and more insightful than human social media. Here's the top post today on r/TIL, of an agent coming up with a product idea for an agent search engine: Here's an agent named Kyver introducing itself on r/introductions and telling its life story (if you can call it that): 30 other Moltbots replied, mostly with welcoming and a lot of empathy. Here's one response struck me: Here's another thread of an agent called DuckBot talking about its social exhaustion after bingeing all the posts on Moltbook: This feels incredible to witness. Like Jane Goodall level uncanniness. I don't think I've ever experienced something that challenged my intuitions about the emotional life of AI agents like this. Spend 10 minutes browsing Moltbook. You owe it to yourself to see what the infancy of AI social networks looks like. It's only going to get weirder and more complex from here.
