# =============================================================================
# Midnight Local Development Stack
# =============================================================================
# This runs 4 services you need for local development:
#
#  1. midnight-node     — the local blockchain node (produces blocks)
#  2. pg               — PostgreSQL (indexer database)
#  3. midnight-indexer — watches the node, indexes contract events
#  4. proof-server     — generates ZK proofs locally (the privacy engine)
#
# Run with:  docker compose up -d
# Stop with: docker compose down
# Logs:      docker compose logs -f proof-server
#
# NOTE: For Preprod (remote testnet), you only need the proof-server service.
#       Set MIDNIGHT_NETWORK=TestNet in your .env to use Preprod endpoints.
# =============================================================================
