The first hackathon with fresh fish as the prize🐟🐟 If in ETHTokyo or around, this is a must go. Kesennuma is a really interesting place, and the local government is very receptive. They're looking into crypto based solutions for civic engagement I had the pleasure to meet

People often ask me why I wake up at 3am and what I work on at that hour. The answer to both questions is the same: My dreams. I’m working on my dreams.

Had some great memories at @Ethereum_JP and with our friends at @NyxFoundation and more! 🇯🇵 :) The ecosystem here feels so youthful! Innovative, bold, yet detail-oriented. Loved seeing how people loosely gathered, then came together with real focus to make things happen!

To make this vision a reality, we would like to begin conversations about next year's sponsorships while the memory of this year's ETHTokyo is still fresh. At this stage, nothing has been decided except our determination to make the hackathon happen again in Tokyo.

ethtokyo関連の情報が結構流れてきていて、特にハッカソンを見てとみに思うのですが、実際に手を動かして作る人というのは素晴らしいですよね。トークン右から左に動かすだけで何かに参与している気になってはいけない、と改めて思います。

During a government shutdown, maybe the legislators should have their paychecks stopped, restrict access to donations and any campaign funds. Could motivate Congressional and Senate lawmakers to do one of their main job responsibilities in a timely fashion.

I just listened to the pitches from the @Ethereum_JP finalists, and every single one of them was fascinating. Yes, Privacy is a human right. It was deeply encouraging to see that the core values of crypto are still alive and well here at a hackathon in Japan. #ETHTokyo2025
