Zero-Install Architecture

The Zero-OS implements a network boot architecture that delivers the operating system to nodes entirely over the internet, eliminating local installation requirements and enabling a stateless computing environment.

Technical Implementation​

The Zero-Install architecture consists of several distinct technical components:

Bootstrap Process​

  1. Bootloader Initialization: A minimal bootloader (supporting ISO, PXE, USB protocols) initializes hardware components and establishes network connectivity.

  2. Node Identity Verification: The bootloader securely retrieves and validates the node's identity from hardware identifiers or trusted platform modules.

  3. Network Configuration: IPv6 and IPv4 connectivity is established, with support for multiple network interface configurations.

  4. Grid Registry Query: The bootloader securely queries the grid registry for information about which operating system components to retrieve based on the node's identity and hardware profile.

  5. Component Retrieval: Required software module metadata is retrieved and verified against cryptographic signatures and hash values.

  6. Kernel Initialization: The Linux kernel boots with minimal configuration optimized for stateless operation.

  7. Core-0 Activation: The primary Zero-OS process (Core-0) initiates and performs self-verification procedures.

  8. Service Activation: Core services including the Zero-Stor filesystem, networking components, and the zero image service initialize to enable workload deployment.

Security Architecture​

The Zero-Install implementation includes several security mechanisms:

  1. Boot Verification Chain:

    • Optional secure boot parameters in system BIOS
    • Optional cryptographic bootloader verification using BIOS certificates
    • Kernel component verification through hash validation
    • Runtime binary verification before execution

  2. Stateless Architecture Benefits:

    • No persistent local state to compromise
    • Fresh operating system on each boot
    • Immune to many persistent malware threats
    • Reduced attack surface

  3. Network Security:

    • Encrypted bootstrap communication
    • Certificate-based authentication
    • Secure channel establishment for component retrieval

Technical Advantages​

The Zero-Install architecture delivers several technical benefits:

  1. Reduced Operational Complexity:

    • No physical installation or on-site maintenance required
    • Automatic updates through network boot process
    • Simplified hardware requirements (no local OS storage needed)

  2. Enhanced Reliability:

    • Consistent operating environment on each boot
    • Elimination of state-related failures
    • Hardware failure isolation through stateless design
    • Simplified recovery through node replacement without data migration

  3. Deployment Efficiency:

    • Rapid provisioning of new nodes
    • Zero-touch deployment capability
    • Consistent environment across heterogeneous hardware
    • Centralized OS version control and update management

Node Deployment Process​

The full deployment sequence for a Zero-OS node follows these technical steps:

  1. Hardware Deployment: Compatible hardware is deployed at the desired location
  2. Resource Farm Configuration: The system is registered on the grid explorer interface
  3. Bootloader Configuration: A minimal bootloader is implemented via USB media or network boot
  4. Network Initialization: Internet connectivity is established and hardware powered on
  5. Boot Sequence: The system automatically retrieves Zero-OS components from the network
  6. Cryptographic Verification: All components are verified against published signatures
  7. Service Initialization: Core services activate and register with the grid
  8. Workload Readiness: The node becomes available for workload deployment

This architecture enables Zero-OS to operate without installation on local storage media (hard disk, SSD), implementing a true stateless architecture that enhances security, reliability, and operational efficiency.

Implementation Status​

The Zero-Install architecture is fully implemented and in production use, providing the foundation for all Zero-OS deployments in the distributed grid infrastructure.
