Validator OS
Validator OS is Mosaic Chain's plug-and-play operating system designed to make validator participation accessible to everyone—regardless of technical expertise.
Running a blockchain validator typically requires deep Linux knowledge, command-line expertise, and hours of manual configuration. Validator OS changes that.
What is Validator OS?
Validator OS is a custom Linux-based operating system (built on Ubuntu/Debian) that comes pre-configured for running Mosaic Chain validator nodes.
Instead of manually installing dependencies, configuring networking, setting up monitoring, and troubleshooting compatibility issues, Validator OS handles everything automatically.
Distributed as an ISO image:
Bootable installer for USB drives (minimum 16GB)
Complete operating system with all validator software pre-installed
No separate downloads or package installations required
Key characteristics:
✅ Plug-and-play design - Minimal configuration required
✅ Accessible to non-technical users - No deep technical knowledge needed
✅ Streamlined validator participation - Get your node running quickly
✅ Built for Mosaic Chain - Optimized for validator operations
✅ Pre-configured environment - All dependencies and tools included
The result: Running a validator node becomes as simple as installing software—no programming degree or IT expertise required. Once installed, your validator runs headless (no monitor or keyboard needed) and can be managed remotely via the validator dashboard.
Core Features
Guided Installation Wizard
Validator OS includes an intuitive installation wizard that walks you through the entire setup process.
What it handles:
Operating system installation
Network selection (Devnet or Mainnet)
Validator machine profile configuration
Validator node credentials creation
VPN registration and authentication
Security hardening
Blockchain synchronization
Installation time: Approximately 15 minutes (plus 2-5 hours for blockchain synchronization)
Integrated VPN Network
Validator OS includes built-in VPN connectivity for secure, reliable network access.
What it provides:
Secure connectivity for your validator node
Automatic configuration during installation
Two-factor authentication for access security
Managed via VPN dashboard
Registration: During installation, you'll register your validator node on the Mosaic VPN network using email verification and an authenticator app.
Security: Multi-layered authentication (machine credentials, VPN registration, two-factor authentication) ensures only you can access and manage your validator node.
Telemetry & Monitoring
Built-in telemetry monitoring tracks your validator's health and performance.
What's monitored:
Node status and activity
Blockchain synchronization progress
Access your data: View your validator's status and performance through the Mosaic Chain Explorer and validator dashboard.
Automatic Updates
Validator OS handles software updates automatically, ensuring your node stays up-to-date with the latest Mosaic Chain protocol changes.
How it works:
When Mosaic Chain rolls out a new update, Validator OS automatically updates your node to the latest version
Updates are applied seamlessly in the background
No manual intervention required
Your validator stays synchronized with the network
Benefits:
✅ No manual software updates required - Validator OS handles everything
✅ Seamless protocol upgrades - Forkless upgrades via Substrate runtime updates
✅ Security patches applied automatically - Stay protected without lifting a finger
✅ Always in sync with the network - Never fall behind on protocol changes
✅ Minimal downtime during updates - Updates are optimized for validator uptime
This is critical: Missing a protocol update could result in your node falling out of sync or being chilled. Validator OS eliminates this risk entirely.
Blockchain Synchronization
After installation, Validator OS automatically synchronizes your node with both Mosaic Chain and Polkadot Relay Chain.
Dual synchronization:
Mosaic Chain: Full sync from genesis block
Polkadot Relay Chain: Warp sync (faster synchronization method)
Parallel processing: Both chains sync simultaneously
Synchronization time: 1-3 hours depending on chain length
Two components:
Chain: Must be fully synchronized before binding Validator NFT
Indexer: Syncs from finalized blocks (does not affect chain operation)
Progress tracking: Monitor synchronization status via validator dashboard and Mosaic Explorer.
Network Selection
Validator OS supports both Devnet (testing) and Mainnet (production) networks. Choose your network during installation.
Switching networks: Requires reinstallation with the latest Validator OS ISO image (version 3.0.0+).
Auto-Restart After Power Outage
With proper BIOS configuration, your validator automatically restarts after power outages and resumes operation without manual intervention.
Recommended: Use an Uninterruptible Power Supply (UPS) for additional protection against power interruptions.
Hardware Requirements
Validator OS is optimized to run on modest hardware while maintaining high performance.
Minimum requirements:
CPU: 4 cores (recommended: 8+ cores)
RAM: 32 GB
Storage: 2 x 1 TB SSD
Network: Stable internet connection with at least 500 Mbps
USB: One USB port for installer (USB stick can be removed after installation)
Recommended setup:
Dedicated server or high-performance desktop
Uninterruptible Power Supply (UPS) for power stability
Ethernet (LAN) connection (more stable than WiFi)
24/7 uptime capability
After installation: Keyboard, monitor, and USB drive can be disconnected. Your validator runs headless.
