you can just do things. you can just have a stupidly simple idea for a drone detection system, so obvious in your head that surely it already exists you can just spend the next weeks hyper focusing on research, only to realize it's not that simple, and maybe you're onto something you can just join a European defense hackathon and get the parts for your first prototype delivered 1 hour before it starts you can just spend 48 hours manically soldering, 3D modeling, printing, hot gluing, taping, cutting, coding firmware, fixing bugs, unrolling fiber optic cables, testing with a mini drone, building a pitch deck, and demoing it on stage where it kind of works but doesn't quite detect the drone you can just apply to an official FPV drone detection crash test in Ukraine, run by Ukraine's Ministry of Defense, without even having a working prototype yet, and get officially invited a few weeks later you can just realize you now have one month to build a working version from scratch, pack all your tools, and fly to the middle of Romania, to your cofounder's house, to spend 3 weeks hacking from 10am to 3am while frantically ordering more parts and bashing your heads against the infinite struggle of building hardware, electronics and software all tightly coupled together you can just try to open a company and a bank account in Portugal while in Romania, and fight the bureaucracy so hard that your bro has to call his mom to physically walk into a civil registry office in the countryside of Portugal, so she tells the registry lady to call you, so you can unlock the company formation process you can just fly back to Portugal to open the bank account in person, go to a Portuguese army innovation conference, and realize how hard it is to innovate in defense without being at war, and how far most European armies still are from the reality of what's happening in Ukraine right now you can just track down and buy the only Mac Studio M4 Max in Portugal, second hand, from a guy in the middle of the country, because it's sold out everywhere with an 8 week waiting list, since it's the only computer with enough compute and low enough power draw to live inside our portable field hub and detect FPV drones in real time you can just decide to travel to a country at war to test your product, and have the trip land just one week after the largest combined Shahed and cruise missile attack that country had seen in over four years of war you can just fly to Budapest, meet your cofounder and spend 2 days in a tiny hobbit house outside the city assembling and soldering the last sensor node, then drive last minute to a field full of wild horses to test the full system with a simple DJI drone, not really sure if it's going to work on the crash test you can just race to the Budapest train station straight off the field, buried in luggage, and board a 20 hour overnight train to Kyiv all by yourself, then talk your way past the Hungarian border police when they get scandalized that a Portuguese guy is rolling into wartime Ukraine with what looks like a weapon in a huge peli case, when it's really just a computer and homemade microphones connected by fiber optics you can just get to Kyiv and spend 2 days locked in your hotel room finishing the system hub, failing to get a GPS fix indoors to test the setup from your hotel bed, while air raid alerts go off every day and you head down to the shelter to wait them out with the other guests, passing around a plastic cup of Ukrainian champagne from Crimea you can just rent a car on the outskirts of Kyiv, get lost because the address was missing one letter after the number, walk 20 minutes at night to find the rental office, and finally get a reliable Skoda to drive to the crash test site at an undisclosed location you can just offer to pick up another participant from the train station on the morning of the test, whose train runs late because it had to be evacuated midway, and strike up a great conversation about defense, AI, Ukraine and acoustic detection the whole way there you can just show up late because you had to navigate to the site on pure vibes and old school map reading, and then start setting up alone while nothing seems to be working you can just beg the organizers for a stronger powerbank to feed the hub, realize after an hour of troubleshooting that the 4th node is dead (and you need at least 4 to detect anything), swap its GPS module right there in the field, and watch it all come alive 5 minutes before the first FPV test flight you can just spend the whole day in the field, eating dust under sun, wind and rain, alongside a field of other manufacturers all chasing the same problem in their own way, while your system hums along detecting and tracking real combat-grade FPV drones in real time, 50 meters out, plotting them on a map like radar, built from a pile of prototyping parts hacked together beautifully, to become a passive acoustic system that nothing can jam, made of 4 homemade microphones connected by fiber optics to a central compute hub you can just not have the official numbers yet, because the organizers are still processing them, but know exactly what you saw with your own eyes, a handmade system tracking combat drones in real time in the middle of a war and use that as fuel to drive you even more obsessed with cracking this problem you can just then take an overnight train to Lviv with all your gear, to compare notes with one of the leading Ukrainian acoustic-detection companies, only to evacuate the station over a bomb threat with your suspicious-looking giant peli hardware case you can just carry on toward Poland, meet a lovely Ukrainian soldier on the train who hands you drip coffee and gives you genuinely great product feedback, but ultimately fails to convince the border officer that you're not transporting a bomb you can just be pulled off the train with all your luggage and spend the next 12 hours questioned by 3 different teams of customs officers, in varying levels of broken english, about who you are, what you're doing, and what every single piece of electronics you're carrying actually does you can just have your whole prototype held at the border for further inspection, maybe to be returned in a couple of months, because nobody could quite believe it's just a regular computer and a bunch of homemade microphones connected by fiber optics you can just find a way to still make it to Vilnius in time for day 2 of the NATO-Ukraine innovators forum, despite losing your flight, and schmooze your way onto the stage to pitch in front of a panel of European defense VCs, running on coffee and zero sleep, in a way that makes sure they remember you you can just do all of that in 80 days, from the initial idea in your head to a working prototype, built with your own hands, that detects and tracks fiber optic guided FPV combat drones in real time, the ones that cannot be detected any other way, in a real test in the middle of Ukraine, so that fewer soldiers die at the frontline to this new class of weapon that has redefined modern warfare forever you can just start doing things and end up with a passive, electronic-warfare-immune acoustic detection system for FPV drones, cheap enough to blanket the frontline, holding up under live battlefield conditions in the most battle hardened country on earth right now you can just do things.

The @ethereumfndn research into post-quantum cryptography is becoming increasingly relevant. 🎥These two talks from the Post-Quantum Meetup held in Rome on May 8 provide a great look into the challenges, research, and implementation efforts already underway. 👇

AI agents, autonomous finance, and onchain coordination are reshaping the way digital economies operate. At ETHMilan 2026, the “Agentic Economy” panel will explore how AI and blockchain are converging across infrastructure, applications, and new economic models. Moderator: Stanislaw Koper @crypto_goblinz, Founder & Head Degen at Weaving Web3 & Canary Protocol Speakers: Ludovico Rossi @Ludovico__Rossi, CRO & Co-Founder at Brickken Alessandro Prandini @Alessandro0016, Co-Founder at unflat limone @limone_eth, Co-Founder at urbe.eth See our speakers in Milan this Thursday/Friday!

Farcaster gets interesting when you look at what people build with it. it’s a corner of the internet where new things get tested before they make sense anywhere else. that means some of it looks like inside baseball from the outside. most new internet behavior does at first. the important part is that people here actually try the early stuff. they use it, argue about it, improve it and keep going long enough for the weird thing to become obvious. that character took years to cultivate. you cannot manufacture it and you cannot recover it once it is gone. we are still figuring out exactly what comes next, but the starting point is simple: don’t break what’s working. make it easier for people here to put new things into the world, find their first curious users, get sharp feedback, and meet others willing to play with weird early ideas. if Farcaster becomes the place people go when they want to try something before the rest of the internet knows what to do with it, that would be a great outcome.

I’ve been thinking about farcon rome since getting back. it's farcaster's annual gathering, except farcaster doesn't run it. someone in the community puts their hand up every year, finds a venue, organizes the whole thing. we don't plan it or fund it. that's been true since the first one in boston in 2022, when maybe 40 people showed up, everyone left the venue together, and just found a restaurant. then LA, then new york, now rome, because the person who volunteered happens to be from rome. I've been to all of them and the thing that still gets me is that no one is obligated to be there. people come because they want to be around each other. a decade from now, in a world full of agents and ai-generated everything, I think events like these will be described as "made with love, by humans." didn't think I'd be forming core memories in rome. grateful to have been there.

The Ethereum Foundation dAI team supports Urbe Hub, Italy's official Ethereum Community Hub. Urbe Hub is the meeting point between AI and Web3: a physical space in Rome where builders, researchers, and the curious come together to build on the convergence between these two frontiers. With the support of the Ethereum Foundation dAI team, we'll keep building this here, in our city.

gg to @Gon0x_ and team it’s great to see them building, learning, scaling since the early Cody days, one of the most addicting miniapp game on World and Base Europe needs more teams and founders like them wish you the best for this next chapter!

I want to thank everyone who gave me feedback after presenting the Garden Project at Farcon Rome. Many people were incredibly supportive, asked how they could become part of it. 💛 🙏 I'd like to start by inviting you all to follow the @garden_org account. And here's a bit more about what’s happening behind the scenes: 1/ I’m deliberately taking my time: observing, researching, designing (literally having the time of my life!) I learned that for a product like the Garden OS, you can’t just manufacture synthetic conditions for success, you have to take your time cultivating it. Real growth emerges only when the underlying systems are healthy. 2/ Garden is not just a poetic metaphor. Nature has spent 3.8 billion years iterating on decentralized system designs for efficient resource distribution and growth. I’m basically trying to learn from the best in business. Additional note: I also like to think that every experience in my life, every person, every success, every failure, and every detour became part of this compost. Perhaps that was the point all along: to build a garden worth leaving behind. Grateful to be building alongside you all.

Last Friday, @VitalikButerin visited the Urbe Hub 🐺 We welcomed researchers from the Ethereum Foundation and a few external visitors for a full day of coworking focused on Ethereum’s post-quantum roadmap. Shoutout to @asanso as well for helping coordinate the day. We opened the Urbe Hub a little over a year ago with a simple goal: to create a place where builders, researchers, and people passing through could sit together, work together, and exchange ideas. Friday felt like a reminder of why we opened these doors in the first place. People helping shape Ethereum spent the day here doing exactly what this space was made for. If you’re building frontier tech, whether in Web3, AI, or beyond, if you live in Rome, or if you’re just passing through, the Urbe Hub is here. Come find us!

Thanks, Vitalik, for signing the @ETHRome logo ✍️
