Verified Anonymous

Project Description

Verified Anonymous provides verification with POAP and protects user privacy with Semaphore.

Source Code

https://github.com/taijusanagi/verified-anonymous

Live App

https://verified-anonymous.vercel.app/

The Demo only works on a local network, see the contracts package to run the local setup.

For the mainnet functionality check, see the below script.

Benefit

This approach offers the following key benefits:

• Reviewers
  • Can give honest feedback while remaining anonymous
  • Verification ensures the authenticity of reviews
• Viewers
  • Read honest reviews from verified users, providing greater trust and confidence in the feedback

How It Works

Technical Detail

• Only targeted POAP users can join the group
• The signal is public, but the actual sender remains hidden with Semaphore.

Team

This project was developed by taijusanagi, a solo hacker who is passionate about decentralized identity.
