Flux is a decentralized cloud infrastructure powered by an incentivized network of independently operated FluxNodes. Fluxd is the blockchain daemon that provides the consensus layer and coin functionality for the Flux ecosystem, including the Flux decentralized cloud and Arcane OS.
- PoUW v2 (Proof of Useful Work): Also known as PON (Proof of Nodes), activated at block 2,020,000 - see the whitepaper
- FluxNode Network: Incentivized node operators power the decentralized cloud infrastructure at cloud.runonflux.com
- Arcane OS: Distributed operating system built on Flux infrastructure
- LWMA3 Difficulty Algorithm: Provides smooth difficulty adjustments
- Delegate System: Supports P2SH-based FluxNode delegation
- fluxd: Full node daemon
- flux-cli: Command-line interface for RPC interaction
- flux-tx: Transaction utility for creating and manipulating transactions
Supported platforms:
- Ubuntu 20.04, 22.04, and 24.04
- Other Linux distributions (see build dependencies)
- macOS
- Windows (via cross-compilation)
