vOPRF-ID

The Web2-ID Nullifiers project enables pseudonymous systems for Web2 identities using verifiable Oblivious PseudoRandom Functions (vOPRFs). It addresses the lack of nullifiers in Web2 IDs, which are essential for anonymous protocols. The project aims to build an infrastructure, like Semaphore, for Web2-ID registration and reuse across applications.

Features and Capabilities

  • Implements a vOPRF protocol for private, deterministic randomness generation.
  • Uses a multi-party computation (MPC) network to enhance security.
  • Employs ZK proofs to verify Web2 identity without revealing it.
  • Aims to create a global registry for Web2 identities.
  • Generates nullifiers for Web2 IDs, crucial for pseudonymous protocols.
  • Integrates with Web2-Web3 bridges like ZK Email and TLS Notary.

Developer Capabilities

  • Build pseudonymous systems for applications like anonymous voting and forums.
  • Create privacy-preserving applications for anonymous interaction with Web2 services.
  • Integrate the vOPRF protocol with existing infrastructure.

Applications

  • Anonymous Voting with Web2 identities.
  • Anonymous Airdrops to users based on Web2 identities (e.g., GitHub).
  • Pseudonymous Forums with limited accounts and spam prevention.

Key Concepts

  • Nullifiers: Prevent double-spending or multiple voting.
  • vOPRF: Allows private, deterministic randomness generation.
  • MPC: Enhances security via multi-party computation.
  • ZK Proofs: Verifies statements without revealing information.
