The problem aadhaar-semaphore solves

Aadhaar Semaphore is a project that integrates the Semaphore protocol with Aadhaar verification, allowing for anonymous group membership and signaling while leveraging Aadhaar for initial identity verification.

1. Aadhaar verification using ZK circuits
2. Anonymous group membership with Semaphore
3. Private signaling within groups
4. On-chain group management
5. Efficient data indexing and querying with The Graph

Challenges I ran into

1. Understanding Semaphore contracts
2. Testing with contracts with mutiple data
