Privacy-Preserving Data Management

Cypher’s infrastructure addresses core challenges in securely managing and querying encrypted data in a decentralized environment:

Encrypted State Persistence

• Ensures all data remains encrypted in storage and during retrieval.

• Incorporates searchable encryption techniques to enable real-time querying of encrypted datasets without decryption.

Zero-Knowledge Proofs (ZKPs)

• Integrates zk-SNARKs and zk-STARKs to validate encrypted computations trustlessly.

• Allows verification of encrypted operations without revealing plaintext inputs or outputs.

Multi-Layer Encryption Framework

• Combines Fully Homomorphic Encryption (FHE) with hybrid encryption techniques to achieve scalability and efficiency.

• Supports applications requiring layered encryption for multi-party data sharing.

Error Handling for Encrypted Smart Contracts

• Implements robust mechanisms for managing errors in encrypted workflows (e.g., tracking errors via TFHE.select).

• Avoids transaction reverts by recording errors and providing granular control over contract execution states.
