Introduction
EthereumZuric.ch hackathon, co-organized by UTXO Foundation and hosted on Devfolio, united the Ethereum community in the most crypto-friendly country, which is also the cradle of blockchain research.
Zürich was one of the last European cities that hadn’t had a major Ethereum-focused event despite its clear importance and the fact it’s home to numerous blockchain & Ethereum startups. But, not anymore!
The Ethereum Zürich hackathon kicked off on 14th April 2023, supporting the local crypto-friendly community, connecting it with industry professionals, and creating new beneficial projects under the guidance of world-class judges, mentors, and advisors.
The areas of interest expanded wide from Ethereum development to virtual machines, blockchain execution, zero-knowledge proofs, data availability & security, cryptography, and academic research. And voting for winning projects was not only up to dedicated judges, but also enabled the hackathon participants themselves to choose their favorite projects through quadratic voting!
Featuring talks across various fascinating topics like Programming Languages, Cryptography, ZKP, Data Availability, P2P Networking, Ethereum Community, Regulations & Compliance, and Tokenomics, the hackathon helped the participants learn about the Ethereum ecosystem at a granular level.
