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).

This POAP proves you have attended ETHDenver 2025. ETHDenver is a Community-Owned Innovation Festival. With community members on six continents, ETHDenver has proven itself one of the most important events on the annual calendar. ETHDenver Is The World’s Largest & Longest Running Ethereum #BUIDLathon Event.

🎊 Thank you for joining Rollcon Brunch, brought to you by Kakarot and the Starknet Foundation. . ​🥕​ About Kakarot ​Kakarot is a zero-knowledge Ethereum Virtual Machine (zkEVM) written in Cairo. It aims to allow users to leverage the scaling benefits of validity rollups while maintaining compatibility with the Ethereum ecosystem. . ​​About Starknet Foundation ​StarkNet is a permissionless decentralized Validity-Rollup (also known as a “ZK-Rollup”). It operates as an L2 network over Ethereum, enabling any dApp to achieve unlimited scale for its computation – without compromising Ethereum’s composability and security, thanks to StarkNet’s reliance on the safest and most scalable cryptographic proof system – STARK.
