docker-compose.mining.yml

# Optional overlay: run Zebra's internal miner. TESTNET ONLY.
#
# This forces the network to Testnet and enables Zebra's experimental
# internal miner, building zebrad from source with --features internal-miner.
# Set ZEBRA_MINER_ADDRESS to a testnet transparent (tm...) address.
#
# Usage:
#   docker compose --env-file .env.docker \
#     -f docker-compose.yml -f docker-compose.mining.yml up -d
#
# See https://dannywillems.github.io/blog/2026/06/02/zcash-mining-zebra-stratum/
