Thanks to @WPReadingClub for having us! 🙏
Two sessions back to back: crypto meeting rural Japan's population decline, and how @ethereum block-building is being rebuilt.

The second session, led by @ETHGasOfficial, went deep on the future of block building & MEV.
Ethereum's 12-second block is being split into 50–100ms execution windows — turning sequencing rights into a tradeable market.

🌍 8 countries. One fishing town.
Last year, 14 developers came to Kesennuma and spent two weeks living and building alongside the local community and government.
Different backgrounds.
Different perspectives.
One shared challenge: imagining new possibilities for Kesennuma.
From conversations with the community to ideas built with technology, this is what Hackatsuon is all about. 🌊

🎨 From last year's banner to this year's website.
The visual identity of Hackatsuon was created by @virkkk_, an Argentine artist, inspired by the unique experience of a residency × hackathon in Kesennuma.
Her work first appeared across our event visuals last year.
Now, it welcomes visitors to the Hackatsuon 2026 website. 🌊
A visual story that continues to evolve with Hackatsuon.
