Overview

Cypher is a Layer 3 blockchain protocol built on Ethereum, designed to harness the capabilities of Fully Homomorphic Encryption (FHE). This enables secure computations directly on encrypted data, preserving confidentiality throughout computational processes.

Unlike traditional blockchain solutions that require plaintext data for processing, Cypher's architecture eliminates the need for decryption at any stage, mitigating exposure to data breaches or malicious actors.

By integrating FHE within its core, Cypher pushes the boundaries of secure, decentralized computation, offering a robust solution for applications with critical privacy and security requirements. These include, but are not limited to:

• Healthcare: Privacy-preserving patient record analysis and diagnostic model execution.

• Finance: Encrypted financial transactions and real-time risk modeling.

• AI-Powered Analytics: Federated learning and privacy-preserving AI inference on sensitive datasets.

Key Technologies

• FHE Integration: Enables computation on encrypted data with secure multiparty operations and dynamic key management.

• Layer 3 Enhancements: Scalable encrypted rollups, compact state proofs, and privacy-focused EVM extensions.

• Privacy Management: Encrypted state persistence, ZKPs for trustless validation, and multi-layer encryption for efficiency.
