# Lethean Home Node
# A self-contained chain node for home users who want to support the network.
# Syncs the chain, runs a wallet with PoS staking, and exposes P2P for peering.
#
# Usage:
#   cp .env.example .env   # edit WALLET_PASSWORD at minimum
#   docker compose -f docker-compose.node.yml up -d
#
# What it does:
#   - Syncs and validates the Lethean blockchain
#   - Peers with other nodes (P2P port 46942)
#   - Runs a wallet that stakes automatically (PoS mining)
#   - Optionally mines with ProgPoWZ (connect external GPU miner)
#
# Earnings:
#   - PoS staking rewards (proportional to balance)
#   - PoW block rewards if mining
#
# Ports:
#   46941 — Daemon RPC (local tools)
#   46942 — P2P (open this on your router for full node)
#   46944 — Wallet RPC (local tools)
