Overview
ArcaneOS is a specially designed, hardened Linux-based operating system built exclusively for FluxNodes. Unlike generic server operating systems, ArcaneOS is stripped down to only the essential components needed to run a FluxNode securely and efficiently, minimizing the attack surface and maximizing performance.
At its core, ArcaneOS implements a cryptographic attestation system that verifies the authenticity of the hardware running each node. This ensures that every node on the network is backed by genuine hardware, preventing spoofing and maintaining the integrity of the entire Flux network. ArcaneOS is a mandatory requirement for Progressive Node Rewards (PNR), making it essential for node operators who want to maximize their earnings.
Key Features
Hardware Attestation
Cryptographic proof of genuine hardware through a secure attestation protocol. Prevents spoofing and ensures every node contributes real compute resources to the network.
Secure Boot Chain
Verified boot process from firmware to OS. Each stage cryptographically validates the next, preventing unauthorized modifications to the boot sequence.
Runtime Integrity Monitoring
Continuous system integrity checks detect tampering or unauthorized modifications in real-time, automatically alerting the network of any anomalies.
Automatic Security Updates
Seamless over-the-air updates keep nodes protected with the latest security patches without requiring manual intervention or extended downtime.
PNR Integration
Full integration with the Progressive Node Rewards system. ArcaneOS attestation is a mandatory requirement for PNR eligibility and enhanced rewards.
Network Hardening
Pre-configured firewall rules, port management, and network isolation ensure nodes are protected against common attack vectors and unauthorized access.
Why Providers Need ArcaneOS
ArcaneOS is not just recommended — it's essential for any serious hosting provider. Here's why it matters for your business:
Required for PNR eligibility — clients on ArcaneOS earn maximum rewards, increasing satisfaction and retention
Automatic security updates reduce maintenance overhead and minimize downtime across your fleet
Hardware attestation provides verifiable proof of hardware quality to prospective clients
Network hardening minimizes security incidents, reducing support tickets and operational costs
