Client Side Proving and Verification with Valida
While most ZK systems today are optimized for server-side execution, there is a growing need for client-side proving—where proofs are generated and verified directly on end-user devices.
Use Cases
Client-side proving and verification with Valida zkVM opens up a range of innovative use cases in blockchain contexts, including:
- Trustless Light Clients for Blockchains: Users can verify blockchain state transitions without relying on a centralized server, enabling decentralized and trustless interactions.
- Private Transactions: Users can prove the correctness of transactions without revealing sensitive data to third parties.
- Decentralized Identity Verification: Users can prove their identity or credentials without exposing personal information to service providers.
How We Implemented Client-Side Proving
We compiled Valida’s execution engine, prover, and verifier to WASM using wasm-pack, enabling browser compatibility.
Key optimizations:
- Minimized memory usage to handle resource constraints.
- Replaced panics with proper error handling for smoother UX.
- Base64-encoded guest programs for easy embedding into apps
Future Improvements:
- Continuations: Breaking long computations into smaller chunks.
- Usability Improvements: Enhancing the DevEx for client-side proving.
- Edge Case Optimization: Ensuring performance in low-memory/power environments.
