Zero-Knowledge Proof Based Private Data Query Services

We design and implement zero-knowledge circuits tailored to your specific data query logic (e.g., proving credit score > X, age verification, transaction history). Built using industry-standard frameworks like Circom and Halo2 for optimal proving efficiency and security.

Deployment of gas-optimized, audited smart contracts that verify ZK proofs on-chain. We ensure compatibility with EVM chains (Ethereum, Polygon, Arbitrum) and L2s, providing a trustless verification layer for your dApp's private queries.

Scalable backend infrastructure for proof generation, handling variable workloads with low latency. We architect systems using Rust/Golang provers and managed cloud services to deliver sub-second proof generation for complex queries.

Secure pipelines to attest off-chain data sources (APIs, databases) for use in ZK proofs. We implement TLSNotary or similar techniques to cryptographically prove data provenance, bridging Web2 data to Web3 privacy.

Comprehensive TypeScript/JavaScript SDKs and APIs that abstract ZK complexity. Enable your frontend and mobile teams to integrate private data queries with simple function calls, accelerating development.

Rigorous security review of the entire stack: ZK circuits, smart contracts, and backend infrastructure. We partner with leading audit firms and employ formal verification methods to eliminate logical vulnerabilities.

Enable selective data sharing for KYC/AML and financial reporting without exposing raw user data. Our ZK circuits generate verifiable proofs of compliance, meeting GDPR and MiCA requirements.

Sell insights from private datasets (e.g., user behavior, transaction patterns) while keeping the source data encrypted. Clients verify query results via ZK proofs, creating a new revenue stream with zero data leakage.

Verify user credentials, asset ownership, or eligibility in under 500ms without revealing the underlying data. Integrate privacy-preserving checks directly into your dApp's user flow for seamless experiences.

Maintain a tamper-proof, cryptographically verifiable audit trail of all data queries and computations. Every proof is anchored on-chain, providing immutable evidence for internal audits or regulatory reviews.

Eliminate the cost and complexity of managing siloed, encrypted databases and complex data-sharing agreements. Our service handles the cryptographic heavy lifting, letting you focus on core product logic.

Launch features competitors can't match: private credit scoring, anonymous voting, confidential DeFi positions. Use privacy as a product feature to attract security-conscious enterprise and institutional users.
