How it's Made

orta integrates a sophisticated suite of technologies.

Software Components:

• Remote Attestation Framework:

  • Phala DStack SDK: Leveraged for managing aspects of the remote attestation process.

  • Custom Attestation Logic: For MRENCLAVE/MRSIGNER validation.

• Smart Contracts (Optional Blockchain Integration):

  • Solidity: Language for smart contracts.

  • Foundry: Toolkit for Ethereum application development.

  • Purpose: Registering trusted values, token incentives, on-chain proofs.

• Mainframe (Manager/Scheduler):

  • Rust: Chosen for performance and memory safety.

  • Key Rust Crates (Hypothetical): tokio, tonic/actix-web, serde.

• TEE Runtime:

  • Gramine LibOS: Core for running unmodified Linux apps in SGX.

• Hardware Interface (Worker Nodes):

  • Intel SGX Driver & Platform Software (PSW): Essential for interacting with SGX hardware.

• Containerization:

  • Docker Runtime: For packaging applications.

  • OCI Image Spec Compatibility.

• ZK-Proof Verification Components:

  • Custom Implementations in Rust and Golang: Flexible for different proof systems.

  • Standardized Interface: For interaction with verifiers.

• Attestation Service:

  • Dedicated Service Microservice: For quote validation, collateral management, trusted registry.

Hardware Requirements (per Node):

• CPU: Intel processor with SGX support enabled in BIOS/UEFI.

• Memory (RAM):

  • System RAM: Sufficient for host OS and Vorta components (e.g., 16GB+).

  • Enclave Page Cache (EPC): Critical hardware resource allocated in BIOS (e.g., 92MB-256MB).

• Storage:

  • OS/Application Storage: SSD recommended.

  • Secure Storage for ZK Proofs & Execution Traces: High-throughput NVMe SSDs.

• Network: High-bandwidth, low-latency NICs (1 Gbps min, 10 Gbps+ recommended).

• Platform Security: TEE-enabled server/cloud instance, Secure Boot, optional TPM.
