Quick Start

Get your node running in minutes

1. Run a Full Node

Download the binary and create a config file:

# Create config directory
mkdir -p ~/.ftc

# Create config file
cat > ~/.ftc/ftc.conf <<EOF
rpcuser=ftcuser
rpcpassword=ftcpass
rpcport=9332
port=9333
connect=3.35.208.160
connect=44.221.81.40
EOF

# Start the node
./ftcd

2. Start Mining

Point the miner at your local node or a seed node:

# Mine to your own node
./ftc-miner \
  --rpc-url=127.0.0.1 \
  --rpc-port=9332 \
  --rpc-user=ftcuser \
  --rpc-pass=ftcpass \
  --address=YOUR_FTC_ADDRESS \
  --threads=4

# Generate a new address
./ftc-wallet --generate

3. Build from Source

Requirements: C++20 compiler, CMake 3.20+, OpenSSL 3.x

# Clone
git clone https://github.com/Kristian5013/flow-protocol
cd flow-protocol

# Build (Linux)
mkdir build && cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
cmake --build . -j$(nproc)

# Run tests (184 tests, 791 checks)
./test/ftc_tests

4. RPC API

Query the node via JSON-RPC:

# Get blockchain info
curl -u ftcuser:ftcpass \
  -d '{"jsonrpc":"1.0","id":1,
       "method":"getblockchaininfo",
       "params":[]}' \
  http://127.0.0.1:9332/

# Other methods:
# getblock, getblockhash,
# getpeerinfo, getmempoolinfo,
# getwork, submitwork,
# getnewaddress, getbalance,
# sendtoaddress, listtransactions
