# DChain node environment — copy to node1.env / node2.env / node3.env and
# customise per-host. These values are read by the node binary via ENV
# fallback (flags still override).
#
# Required:
#   DCHAIN_VALIDATORS      Comma-separated Ed25519 pubkeys of the initial
#                          validator set. All three nodes must agree on
#                          this list at genesis; later additions happen
#                          on-chain via ADD_VALIDATOR.
#   DCHAIN_ANNOUNCE        Public libp2p multiaddr peers use to dial this
#                          node from the internet. e.g.
#                            /ip4/203.0.113.10/tcp/4001
#
# Optional:
#   DCHAIN_PEERS           Bootstrap peer multiaddrs. Auto-filled by
#                          --join if omitted.
#   DCHAIN_GOVERNANCE_CONTRACT   Deployed governance contract ID (hex).
#   DCHAIN_RELAY_FEE       µT per message when registering as a relay.
#   ACME_EMAIL             Email for Let's Encrypt (TLS expiry reminders).
#   DOMAIN                 Public hostname — Caddy issues cert for this.
#
# Security:
#   Key files are bind-mounted at runtime; do NOT put private keys in this
#   file. Each node needs its own identity — generate with
#     docker compose run --rm node1 /usr/local/bin/client keygen --out /keys/node.json
#   and copy out with `docker cp`.
