# zkBob ETHGlobal Tokyo Retro By [BOB](https://paragraph.com/@bob-16) · 2023-04-21 --- The zkBob team had an enlightening trip to Tokyo to share our vision of a stablecoin future enhanced with personal financial privacy. The community was extremely welcoming, and we met some 🧰 💪🎌 hackers building the next generation of applications to supercharge the Ethereum universe. 18 projects in Tokyo explored adding zkBob into their Dapps! It was difficult to narrow the winners down, but in the end we chose 5 teams that came up with interesting use cases and incorporated privacy into their projects with [zkBob](https://zkbob.com/). 🇯🇵 Community -------------- We’re grateful for our community members around the globe 🌎🌍🌏! Our friend [@zuckzuckland](https://twitter.com/zuckzuckland) in Japan helped with the booth and to spread the word about the BOB stablecoin, optional privacy, and compliance best practices. ### A nice walkthrough of the zkBob app in Japanese! ### Bloggers and media were more than happy to spread the word about zkBob!

Thanks to everyone who stopped by our booth to chat, and to all the hackers who chose to work with zkBob. Basic personal privacy is needed for so many different applications, and it’s great to see new implementations with zkBob at each hackathon we attend. We are excited to see how these projects continue to unfold over the coming months and help bring basic, responsible privacy to all blockchain users. We look forward to seeing you at the next event! 💜 The zkBob Team --- *Originally published on [BOB](https://paragraph.com/@bob-16/zkbob-ethglobal-tokyo-retro)*
