Zero-Knowledge Proof Development

Keyko develops zero-knowledge cryptographic systems for Web3 applications, with proven expertise in implementing privacy-preserving solutions and ZK-based identity systems. Their ZK capabilities focus on practical implementations that solve real-world privacy and security challenges.

ZK Implementation Expertise

Zero-knowledge soulbound tokens (zkSBT): Advanced implementation of privacy-preserving soulbound tokens combining ZK proofs with non-transferable NFT mechanics

Privacy-preserving applications: Building systems that enable verification without revealing underlying data

ZK-based identity solutions: Decentralized identity systems leveraging zero-knowledge proofs for credential verification

Custom ZK implementations: Development of ZK circuits and proving systems tailored to specific application requirements

Masa Network zkSBT Implementation

Keyko's flagship ZK project is the zero-knowledge soulbound token system for Masa Network, a decentralized AI & LLM network. This implementation demonstrates Keyko's ability to combine cutting-edge cryptography with production-scale deployment:

• Deployed zkSBT system supporting 1.4 million users
• Enabled privacy-preserving identity verification and data contribution
• Integrated ZK proofs with decentralized AI data network infrastructure
• Facilitated 41.2 million data points contributed while preserving user privacy

Technical Approach

Keyko's ZK development combines:

• Security-first implementation: Rigorous testing and cryptographic security validation
• Multi-chain deployment: ZK systems deployed across Ethereum, Celo, NEAR, and other platforms
• Production scalability: ZK implementations designed to handle real-world user volumes
• Integration expertise: Seamlessly integrating ZK proofs with smart contracts, frontends, and backend systems

Use Cases

Keyko has delivered ZK solutions for:

• Decentralized identity: Soulbound tokens for privacy-preserving credential systems (Masa Network)
• Data privacy: Enabling users to contribute data to AI networks without revealing personal information
• Verification systems: Proving attributes or credentials without disclosing underlying data

Innovation Focus

Keyko explores cutting-edge applications of zero-knowledge proofs beyond standard implementations, helping clients identify meaningful ZK applications that create real user value while preserving privacy and security.
