blockchain/docker/docker-compose.nodes.yml

# Lethean Chain Nodes Only — minimal network simulation
# 3 nodes + miner, no explorer/trade (for testing consensus, HF activation, reorgs)
#
# Usage:
#   docker compose -f docker-compose.nodes.yml up -d
#   # Start mining on node1:
#   docker exec lthn-node1 curl -X POST http://127.0.0.1:36941/start_mining \
#     -H 'Content-Type: application/json' \
#     -d '{"miner_address":"YOUR_iTHN_ADDRESS","threads_count":2}'
#   # Check sync status:
#   for n in 1 2 3; do
#     echo -n "node$n: "; docker exec lthn-node$n curl -s http://127.0.0.1:36941/json_rpc \
#       -H 'Content-Type: application/json' \
#       -d '{"jsonrpc":"2.0","id":"0","method":"getinfo"}' | python3 -c "import sys,json; print(json.load(sys.stdin)['result']['height'])"
#   done
