Berlin Hackathon 2025 - Cardano Community Event Recap

:construction: Cardano Takes Berlin

:clapper_board: Don’t forget to turn the CC on for English subtitles!

What happens when you mix curiosity, collaboration and caffeine in the heart of Berlin? You get a weekend where Cardano builders showed up, spoke up, and pushed the envelope.

Set during Berlin Blockchain Week, this grassroots gathering focused on doing what truly matters: building tools, asking the tough questions, and imagining what Cardano can become when it’s shaped by the people who use it every day.


:microphone: Real Talk, No Filters

Two Roundtable Talks became the pulse of the weekend.

  • Friday: Dev tools & the builder experience — what’s missing, what’s working, and where we go next.
  • Saturday: Sustainability on-chain — not just eco talk, but how to fund, govern, and evolve the ecosystem without losing its soul.

No keynotes. No scripts. Just real voices, real challenges, and a shared willingness to rethink how we’re building this chain. Stay tuned for this in the Cardano Community YouTube Channel https://www.youtube.com/@CardanoCommunity


:hammer_and_wrench: Beyond Hype, Into Code

Fresh from the NMKR Hackathon, teams demoed smart, practical prototypes.

One standout? A vocal AI agent that lets users interact with their wallets using natural language. Think: “Send 5 ADA to Anna”—and it happens.

It wasn’t about moonshots. It was about small, sharp tools that make life better for devs and users alike.


:camera_with_flash: Community Holds The Mic – Vol. 2

Back by demand, this series captured bite-sized interviews with developers, designers, and builders across Europe. The mood? Honest, energized, and ready to build. If the mic could talk, it’d ask for a coffee refill and a testnet.


:handshake: Powered by People

None of this happens without the humans behind the handles.

Big thanks to:

  • :brain: @nmkr_io – for leading with open tooling
  • :house: @w3_hub – for opening the doors (and the fridges) And to everyone who showed up to speak, code, or just listen.
  • :classical_building: @Cardano_CF – for presence and perspective

Berlin didn’t give us all the answers, but it gave us better questions.

And that’s a great place to build from.

What’s your favorite takeaway from the Berlin Hackathon?
