[aguzmant103]

Explore a list of ideas and cool projects to build with Semaphore. Even if some iterations of these ideas have already been built, you can take inspiration from them to build something new. If any of these ideas are interesting to you, comment on the discussion or join us on Telegram and we can expand on a possible implementation with you!

• Build a private “Secret Leader Election” protocol for validators.
• MPC - Simple Semaphore 3PC.

We recommend focusing on identifying existing open-source projects in a specific area and enhancing them with Semaphore rather than building a complete solution from scratch. For example, if you want to build an app to share anonymous feedback, you could enhance existing public platforms like Decidim (an open-source participatory democracy tool) by integrating Semaphore as an extension instead of re-implementing an entire infrastructure.
