We met at ETHBratislava or one of the side events. corpus.core builds blockchain core technology for Ethereum and other L1s and L2s. With the colibri.stateless, we develop a Trustless Stateless Ultra-Light-Client. Never again simply trust data from any RPC provider. With colibri.stateless, every data can be validated by trustless proofs. No sync is needed, no state is stored. It is so small that it runs on any IoT hardware, mobile, and web apps, etc. We love to connect with you to support integration in your dApp or extend colibri.stateless to your ecosystem. This is how blockchain access is meant to be.

ETHBratislava 2025 is not just another Ethereum conference, it is our bold attempt to put Central Ethereum Europe (CEE) on the map. Again. For the second time we bring together builders, dreamers, and skeptics from 14+ countries to talk about real-world use cases, restaking, regulation, and yes, also challenges. This POAP is for those brave enough to show up, learn, ship, or simply survive two days of talks, hackathon chaos, and the legendary BratisRave. Thanks for being part of this madness.

Get ready for the next ETHBratislava, celebrate Global Pizza Day 🍕 with us ​Join us under the open sky as we kick off ETHBratislava with a rooftop launch party celebrating two things that shaped crypto history—hackers/builders, and… pizza. 🍕 ​Just like Laszlo’s legendary 10,000 BTC pizza purchase marked a moment in crypto prehistory, ETHBratislava is the next step forward, fuelling innovation, collaboration, and the decentralized future. This is where ideas get baked (just like pizza, but with fewer toppings and more cartoon animals and smart contracts).
