Looking Back At ETHBerlin³: A Hackathon Extravaganza ✨

Looking Back At ETHBerlin³: A Hackathon Extravaganza ✨
Here’s a recap of ETHBerlin³ 2022 — a hackathon extravaganza, a cultural festival, an educational event, a platform for hacktivism, and a community initiative to push the decentralized ecosystem forward.

ETHBerlin³ hackathon, organised by the Department of Decentralization and hosted on Devfolio, kicked off on September 16 and brought together hundreds of developers, mentors, and judges to innovate & build on the latest technologies. An astounding 100 projects were built during this 3-day hackathon.

After successful events in 2018 and 2019, ETHBerlin decided to reaffirm its commitment to the ecosystem and founded the Department of Decentralization. The DoD is responsible for initiatives beyond organizing hackathons; and also seeks to support the projects coming from their community.

In 2022, they pushed even further into becoming a festival for people from all backgrounds and, most importantly, a hub where builders were able to get their creative juices flowing by discovering various cultural and educational experiences spread across the weekend.

Developers from around the globe ranging from high school students to PhD scholars joined the hackathon and built various projects. It was thrilling to see projects built on diverse ideas such as the EVMs, smart contracts, ZK proofs, DAOs, NFTs, IP-NFT, etcetera, and won bounties from a pool of over 55,000 DAI. The event also included keynotes, panel workshops, fireside chats, and mentorship sessions, making the atmosphere completely immersive and energetic.
