Privacy-Preserving Enterprise Access Control

Implement selective disclosure of user credentials using zk-SNARKs and zk-STARKs. Users prove eligibility (e.g., KYC status, role) without revealing underlying data, ensuring GDPR and CCPA compliance.

Define and enforce complex, multi-attribute access policies (e.g., department=Finance AND clearance>=3). Policies compile to verifiable ZK circuits for on-chain or off-chain evaluation.

Deploy access control logic across EVM chains (Ethereum, Polygon, Arbitrum) and non-EVM environments. Leverage Chainlink CCIP or native bridges for interoperable credential verification.

Optimized prover backends using PLONK and Groth16 for sub-second proof generation in browser and mobile environments. Includes managed proving services for enterprise-scale workloads.

Secure, non-custodial key management with social recovery (ERC-4337) and multi-party computation (MPC) options. Eliminates single points of failure for enterprise credential wallets.

Implement granular, on-chain role-based access control (RBAC) with multi-signature approvals. Define policies for executives, departments, and partners with enforceable, tamper-proof logic.

Maintain full ownership and cryptographic control over access policies and audit logs. Decentralized architecture prevents vendor lock-in and ensures business continuity.

Securely share data and system access with external vendors, auditors, and partners using verifiable credentials. Create temporary, revocable access tokens with precise permissions.

Mitigate insider threat and credential theft with cryptographic proofs instead of passwords. Every access attempt is verified on-chain, creating a transparent security perimeter.
