Project Overview
The Client-Side Proving project aims to develop practical and efficient zero-knowledge (ZK) proving systems tailored specifically for mobile devices. By exploring various proving systems - including Binius, Spartan, Plonky2, Scribe, and WHIR - we provide benchmarks, insights, and optimized implementations that enable performant client-side applications.
Objective
Our primary objective is to identify and optimize ZK proof systems that require minimal resources, have no trusted setup, and maintain post-quantum security. These efforts are particularly focused on supporting applications in digital identity, secure communications, and privacy-preserving credential management.
Project Status
- Stage: MVP Development
- Status: Active
- Team Lead: Alex Kuzmin
- Team Members: Guorong Du
Technical Approach
The project rigorously benchmarks mobile-friendly ZK proving systems based on critical criteria including computational complexity, RAM efficiency and proof size. Key innovations and strategies include:
- Benchmarking Binius, Spartan, Plonky2, and Scribe for mobile usability.
- Optimizing RAM usage through streaming techniques.
- Evaluation and integration of lookups to enhance proving efficiency in computationally intensive ZK circuits.
Milestones
- April 2025: Established baseline benchmarks for common mobile hardware.
- May 2025 (planned): Comprehensive benchmarking results published for selected ZK proving systems.
- June 2025 (planned): Optimization of Spartan using WHIR PCS and/or Scribe's read-write streaming techniques.
- Q3 2025 (planned): Collaboration with an Identity initiative, integrating optimized proving systems.
Applications
Client-Side Proving enables numerous privacy-focused mobile applications, including:
- Mobile Digital ID wallets ensuring user privacy.
- Anonymous online communication and collaboration tools.
