Downloads
ferminux-geth is the network's node and CPU miner in a single static binary. The desktop miner wraps it in a point-and-click app.
The Windows ZIP adds double-click START-MINING.bat and START-NODE.bat wrappers plus a plain-English README — extract it before running anything. The binary is unsigned, so SmartScreen shows a "Windows protected your PC" warning: More info → Run anyway.

Quickstart
The genesis is baked into the binary — an empty datadir joins ChainID 3961. No config files, no flags required.
# Install in one line (Linux / macOS — verifies SHA-256)
curl -fsSL https://ferminux.net/install.sh | bash
# Zero config — an empty datadir syncs the Ferminux Network (ChainID 3961)

# With local JSON-RPC for wallets and tooling
ferminux-geth --http --http.api eth,net,web3Chain data lives in ~/.ferminux (macOS: ~/Library/Ferminux; Windows: %LOCALAPPDATA%\Ferminux). The node discovers peers through the built-in bootnodes at boot1–3.ferminux.net.
# Mine with N CPU threads; rewards go to your address (6 FMX per block)
ferminux-geth --mine --miner.threads 4 --miner.etherbase 0xYourAddressFirst start generates the Ethash DAG (~1 GB, a few minutes). Blocks seal immediately after. Any address from any EVM wallet works as the etherbase.
# Any stock Ethash miner works. Point lolMiner at the public stratum endpoint:
lolMiner --algo ETHASH --pool stratum+tcp://pool.ferminux.net:3333 --user 0xYourAddress.rig1Mining solo? Run the stratum proxy from the /proxy component of this repo next to your own ferminux-geth node and point the same command at it.
