Cypher Layer 3 Tech Integration

Cypher's Layer 3 architecture leverages advanced technologies such as Nitro, Orbit, and Anytrust to create a high-performance blockchain framework optimized for Fully Homomorphic Encryption (FHE). These technologies enable secure, scalable, and efficient encrypted computations, making Cypher ideal for privacy-centric decentralized applications.

Cypher Layer 3 Architecture

Cypher’s Layer 3 extends standard blockchain functionality by integrating specialized protocols to support privacy-preserving computations:

  • Secure Encrypted Computation: FHE operations allow data to remain encrypted throughout the entire computational process.

  • High Throughput and Scalability: Processes large volumes of encrypted data with minimal latency.

  • Application-Specific Protocols: Tailors its infrastructure to accommodate unique requirements of privacy-focused dApps.

Nitro Framework

The Nitro framework is at the core of Cypher’s rollup infrastructure, offering a high-performance execution layer:

Optimized Rollup Protocol

  • Aggregates encrypted transactions into efficient rollup batches, reducing gas costs and enhancing scalability.

  • Minimizes latency in processing encrypted workloads while maintaining robust security.

Full EVM Compatibility

  • Ensures seamless execution of encrypted smart contracts written in Solidity, enabling easy adoption by existing Ethereum developers.

WebAssembly (WASM) Support

  • Allows execution of complex computational tasks, essential for FHE-based operations, alongside standard EVM logic.

Orbit Framework

The Orbit framework provides the foundation for creating custom Layer 3 environments optimized for FHE:

Custom Execution Environments

  • Tailored for privacy-preserving computations, enabling specialized cryptographic workflows.

  • Facilitates enhanced privacy controls while maintaining compatibility with the overall ecosystem.

Independent Operations:

  • Supports standalone execution environments with unique consensus protocols and decentralized governance.

Anytrust Technology

The Anytrust framework ensures efficient and secure data availability for encrypted computations:

Efficient Data Handling

  • Reduces dependency on primary blockchain layers by distributing encrypted data among trusted committee members.

  • Ensures verifiable and consistent availability for encrypted contract states.

Performance Optimization:

  • Minimizes bandwidth usage for state transitions while maintaining high throughput and reliability for FHE workloads.

Confidential Computation with fhEVM

Cypher’s Fully Homomorphic Encryption Ethereum Virtual Machine (fhEVM) is the backbone of its privacy-preserving architecture:

Native Encrypted Computation

  • Supports mathematical, logical, and conditional operations directly on encrypted data without decryption.

  • Ensures sensitive data and computation states remain secure throughout the lifecycle.

Efficient Rollup Execution

  • Integrates seamlessly with Nitro rollups to enable fast and scalable encrypted transactions.

Data Integrity and Privacy

  • Uses Anytrust mechanisms to manage encrypted states securely, ensuring consistent access and storage.

Technical Repositories

Cypher’s technology stack is available in open-source repositories for developers to build and integrate with its Layer 3 environment:

  • Includes the primary blockchain implementation and encrypted rollup mechanisms.

  • Enables execution of encrypted smart contracts and fully homomorphic computations.
