ETHAmsterdam 2022

ETHAmsterdam was one of our best events yet—and we’re only getting started.

For one weekend this April, we brought the Ethereum Developer community together for the hackathon-to-end-all-hackathons. ETHAmsterdam was an event two years in the making, representing everything our team had learned along the way, and opening a window onto the bright future of our ecosystem. Three days, 165 Projects, 700 hackers, and 47 talks & workshops later, we think it’s safe to say ETHAmsterdam was one of our best events yet.

🏁 ETHAmsterdam Kick-off & Keynote

After two years of digital events, we were ready to bring the ETHGlobal community back together for the event we’d all been dreaming about in quarantine. Needless to say, a lot has changed since 2019. To kick things off in Amsterdam, we hosted a conversation with Vitalik Buterin on the state of the Ethereum community, what has changed since the first lockdowns, and what happens next for builders across the world. This riveting discussion brought the audience to the edge of their seats and set an optimistic tone for the rest of the event.

Don’t miss this incredible discussion on the future of Web3.

The main hall started to buzz as new teams and projects got their start. From the opening ceremony onwards, teams were able to work on their projects non-stop, opting to sleep only when physically necessary. Giant beanbag chairs littered the floor, and hackers got to work building their big ideas, as there was no time to waste.

As the hackers got to work, others poured in to our ETHAmsterdam Workshop sessions, catching talks from Konstantin Tkachuk, Đorđe Mijović, Ulysse Ramage, Eric Tang, and many more. These workshops were designed to give hackers valuable insights that could inform their hackathon builds, but many showed up just to meet and learn from our incredible speakers.

⏰ Hackathon Day 2

Saturday morning started early for most, with many hackers getting their days rolling by grabbing coffee and refreshments. New energy started to take shape within the crowd, replacing the calm that had fallen over the venue after the midnight talks had let out. Hackers were eager to participate in back-to-back workshops, build their projects, and meet new teammates, and Day 2 was packed with opportunities.

By noon, the Main Hall was once again buzzing with excitement. Workshops from Alex Gluchowski, Warren Paul Anderson, and David Lin sparked conversations that echoed through the walls of the Buers van Berlage. After a quick lunch, we hosted a number of talks from ecosystem leaders like Juan Benet, Marius van der Wijden, Yoav Weiss, Remco Bloemen, Chris Hager, and Georgios Konstantopoulos.

Our mission since day one has been to onboard as many developers and creatives to the Ethereum ecosystem as possible. These talks and workshops are one of the ways we support the progression of the space. You can view any of the ETHAmsterdam sessions by going to our YouTube channel.

Feeling the Magic

ETHAmsterdam was so much more than just hacking and workshops. We offered group activities for hackers looking to take a mental break from their projects throughout the weekend. Our events are for the community, in every sense of that word. Though high-level workshops are always sought after, sometimes it’s the more human moments from our events that stand out in our memories.

From Sound Baths to Delftware Tile workshops, hackers were able to let off steam in creative ways, adding a level of fun to the weekend.

🚀The Final Day

As the countdown to the submission deadline approached, a mix of nervous excitement could be felt throughout—no doubt spurred on by the collective all-nighter that had just occurred. A wave of relief spread through the Main Hall as each team successfully submitted their project, with high-fives and celebratory shots of Espresso all around.

Main Judging began almost immediately following the submission deadline. 21 Judges joined us to sort through the hackathon projects, giving teams vital face-time and feedback from ecosystem leaders. Partner Judging started shortly after, spanning into the early afternoon as hackers took time to live demo to Partner Teams at their booths.

Smiles all around as our teams submitted their hackathon projects.

As soon as the judge’s scores were in, our team went into overdrive preparing the announcements for the closing ceremony and contacting our chosen Finalists. After much deliberation, 13 teams were chosen to represent some of the most innovative and well executed projects to come out of ETHAmsterdam. These nascent projects offer a window into the future of our ecosystem, and we’re sure they’ll go far. Take a look at their winning projects below, and learn more about all the teams who participated via our Hacker Showcase.
