Quick Start

First-Time Setup (new network)

git clone https://github.com/FairCoinOfficial/FairCoin.git
cd FairCoin
chmod +x genesis-mine.sh
./genesis-mine.sh

This script automatically installs dependencies, mines the genesis blocks, patches the source code, and compiles everything.

After running, generate your cryptographic keys following doc/GENERATE-KEYS.md, then recompile.
