😄 Totally fair reaction! We're building this with input from the real people we meet in each city and, right now, that means just a handful of users per location. So yes, some early data might feel off.

But that's the vision: as more travelers join and contribute, we'll be able to show cost of living based on your standards, your network, and your lifestyle, not some generic average (that comes from the power of the Nostr Social Graph).

In the future, your Satlantis experience will reflect a personalized view of the world, shaped by people like you.

We're just getting started and each one of you is helping shape it.

Satlantis is a social network for nomads and travelers, where your map meets your social graph.

It shows you where your people are: Bitcoiners, sovereign individuals, frequent travelers, digital nomads... and what's happening in each city. No constant GPS tracking. No creepy surveillance. Just meaningful connections in the cities you look into.

Whether you're looking for the best Bitcoin meetup in Barcelona, coworking buddies in Medellín, or a freedom-loving café in Lisbon, Satlantis makes it easy to discover people, events, and local gems that actually match your lifestyle.

Built on Nostr, it's decentralized, censorship-resistant, and yours to own. No fees, no ads, no algorithms trying to trap you.

If you believe in freedom, privacy, and global community, Satlantis isn't just another travel app. It's your sovereign companion on the road.

Sure!! The Barcelona Bitcoin Community is a passionate collective of enthusiasts, developers, and advocates dedicated to promoting the adoption and use of Bitcoin. We believe in the power of decentralization and the importance of financial freedom for all. Our community is driven by the desire to make Bitcoin accessible to everyone, and we offer various free services to support this mission. We're not here to make a profit, we're here to empower people!

As a frequent traveler, digital nomad, startup entrepreneur, events manager... I felt like Satlantis was for me, so I reached out to him once I saw his presentation in BTC Prague in 2024, just when he was starting to build Satlantis.

Here's some more info about how I got there: https://www.youtube.com/watch?v=8x4j1RxFgCY&lc

I've been there! I remember my first flight as a teenager. I was even alone in the airplane for the first time!!

The anxiety comes from the fear of the unknown. The easier first step to overcome that fear is learning how a plane flies. Let me try to put it with a metaphor:

Think of the air like a road, and the plane's wings like a car's wheels. Turbulence is just like bumps or potholes. It feels shaky, but it's not dangerous. Planes are built to handle way more than that, and pilots deal with it all the time.

You've got this ✈️💛

I think I already attached a lightning wallet. Is that what you are suggesting?

What a difficult question!!!! Can you give me a small list to choose from?!?!?! I'm starting with the blue light blockers, but I think it's not a conspiracy theory...

hahahah, that's the pilot life 😅

It’s called "Collections".

Basically, it lets you save all your favorite spots in each city you travel to (restaurants, coworking spaces, cool landmarks, whatever). Think of it like creating your own personal map for every city you've loved.

And the best part? You can share those lists. Publicly, if you want to help others. Or privately, just with friends. So next time someone asks you “where should I go in Mexico City?” Boom, just send them your Collection.

I've wanted this for ages. It makes Satlantis feel like your travel brain, but organized and beautiful.

Launching very soon. Can't wait to use it myself. 🙌🌍

I used to fly to most major airports in Europe, North of Africa and West of Russia. I have very good memories of Nice Côte d'Azur Airport, it's a piece of land surrounded by water, so... you better land where you are supposed to... or else... sleep with the fishes 🐟🐟🐟

Done! Thank you :)

Great question to start with!

As an airline pilot, one of the first things you learn in flight planning is that the Earth is a globe, not just because it’s what textbooks say, but because you see and fly it every day. Pilots don’t just rely on visual confirmation from high altitudes (though yes, you can see the curvature from a cruising altitude of 35,000 feet on a clear day); we also have to understand the shape of the Earth to fly efficiently.

Let me explain:

🌍 We fly Orthodromic Routes (great circles) When planning long-haul flights, we don’t fly in a straight line on a flat map. We use what’s called the orthodromic route, or great circle route, the shortest path between two points on a sphere. On a 2D map, this looks curved, but in 3D space, it’s actually the shortest distance.

That’s why a flight from New York to Tokyo, for example, curves up over the Arctic instead of going straight west. If the Earth were flat, the shortest path would be a straight line across the Pacific, but that’s not how it works.

🧭 Loxodromic Routes are for simplicity, not efficiency Sometimes, especially in older navigation systems or short-distance flights, we might use a loxodromic (rhumb line) route: one that maintains a constant compass bearing. On a flat map, it looks straight, but on a globe, it's longer and spirals toward the poles. It's easier to follow but less fuel-efficient.

The fact that we even distinguish between these two types of navigation proves we’re dealing with a curved surface, not a flat one.

✈️ High Altitude Views Seal the Deal From 35,000 feet, with good visibility, you can see the horizon gently curve, especially over oceans or polar regions. It's subtle, but real. And the higher you go (like in a business jet or Concorde), the more obvious it becomes.

So from my experience, I'd say that the Earth isn’t flat. If it were, our navigation systems, flight routes, fuel calculations, and even satellite communications wouldn’t work the way they do.
