Run the project (macOS)
This guide gets you to a running node on macOS. Track 1 (Docker Compose) is the recommended path; Track 2 (bare metal) is documented at the bottom for advanced setups.
Track 1: Docker Compose (recommended)
Prerequisites
Verify both are present:
docker --version
docker compose version
Use the docker compose form (with a space). The legacy hyphenated docker-compose is the deprecated Python script and is not supported.
Three-step quickstart
git clone https://github.com/kynesyslabs/node.git && cd node
cp .env.example .env
docker compose up
The first run pulls images and builds the node container, which can take a few minutes. Subsequent starts are near-instant.
When the stack is healthy:
- Node RPC:
http://localhost:53550 — try curl http://localhost:53550/info
- Grafana:
http://localhost:3000 (default admin / demos)
- Prometheus:
http://localhost:9091
Tour of .env
.env.example is the canonical template. The defaults work for local development. The variables you are most likely to touch:
| Variable | Default | Notes |
|---|
CONSENSUS_TIME | 10 | Block production interval (seconds). |
RPC_FEE | 1 | Per-tx fee component. Total flat fee = RPC_FEE + NETWORK_FEE + BURN_FEE (default 1+1+1=3). |
NETWORK_FEE | 1 | Per-tx fee component. |
BURN_FEE | 1 | Per-tx fee component. |
RPC_PORT | 53550 | Host-mapped RPC port. Change if 53550 is taken. |
EXPOSED_URL | http://localhost:53550 | Public URL advertised to peers. Loopback default is fine for local dev — set it to your reachable address before joining a real network. |
OMNI_ENABLED / OMNI_PORT | true / 53551 | OmniProtocol binary RPC. Modes via OMNI_MODE: HTTP_ONLY, OMNI_PREFERRED, OMNI_ONLY. |
TLSNOTARY_ENABLED | true | Set to false to skip TLSNotary entirely. |
TLSNOTARY_SIGNING_KEY | (empty) | Leave empty in default docker mode — the sidecar manages its own key. Only set when TLSNOTARY_MODE=ffi. |
GRAFANA_ADMIN_PASSWORD | demos | Change this. |
COMPOSE_PROFILES | monitoring,tlsnotary | Which compose profiles to bring up (see below). |
Leave PG_HOST=postgres and TLSNOTARY_HOST=tlsnotary exactly as shipped — those are the in-network service names used by docker compose.
Old docs referenced RPC_FEE=5 and SERVER_PORT. Both are wrong. The current names are RPC_FEE (default 1, plus NETWORK_FEE=1 and BURN_FEE=1) and RPC_PORT.
Compose profiles
COMPOSE_PROFILES in .env controls the optional services:
| Profile | Adds |
|---|
| (none) | postgres + node — bare minimum |
tlsnotary | TLSNotary sidecar (HTTPS attestation) |
monitoring | Prometheus + Grafana |
full | node-exporter (host CPU/RAM/disk metrics) — pair with monitoring |
neo4j | Neo4j (only for CGC/KYC features) |
# Default — postgres + node + tlsnotary + monitoring (uses .env)
docker compose up
# Minimal — only postgres + node (also set TLSNOTARY_ENABLED=false in .env)
COMPOSE_PROFILES= docker compose up
# Add host-level metrics
COMPOSE_PROFILES=monitoring,tlsnotary,full docker compose up
Common operations
# Follow logs
docker compose logs -f node
# Update to the latest source
git pull
docker compose up -d --build
# Stop containers, KEEP volumes (your identity, chain data, etc.)
docker compose down
# Stop AND DELETE all volumes — nuclear, destroys identity + state
docker compose down -v
State persists in named Docker volumes prefixed demos_ (e.g. demos_node_state holds .demos_identity, demos_pgdata holds chain data, demos_grafana_data holds dashboards). They survive docker compose down but not docker compose down -v.
Going public
Before joining a real Demos network from a Mac that other peers should reach:
- Set
EXPOSED_URL in .env to your reachable address — public IP or DNS — not localhost.
- Open inbound TCP for
53550 (RPC), 53551 (OmniProtocol), and 7047 (TLSNotary, if enabled) on your router/firewall before advertising the public URL.
- Seed
demos_peerlist.json with bootstrap peers from the team. Do not invent hostnames; use the values the team publishes.
See INSTALL.md for the full peerlist seeding procedure.
Troubleshooting
| Symptom | Fix |
|---|
docker compose: command not found | You have the legacy Python docker-compose. Install the v2 plugin via Docker Desktop or the official guide. |
Port 53550 already in use | Set RPC_PORT (and EXPOSED_URL) to a free port in .env, then docker compose up -d. |
EXPOSED_URL warning at startup | Expected for local dev. Set EXPOSED_URL to a routable address before joining a network. |
| Postgres connection refused | Postgres takes a few seconds to become healthy on first boot. The node waits via depends_on. If it persists, check docker compose logs postgres. |
Track 2 runs the node binary natively via Bun and uses Docker only for a Postgres sidecar managed by the ./run script. Pick this path for core development, kernel-level debugging, or TUI-driven operation.
The macOS-specific quirks (source $HOME/.zshrc instead of .bashrc, Docker Desktop instead of apt-installed Docker) are handled by the upstream install scripts. The full walkthrough — prerequisites, ./scripts/install-deps.sh, identity generation, peerlist setup, and ./run flags — lives in the source of truth:
For the bare-metal path, override these in your .env:
PG_HOST=localhost
PG_PORT=5332
TLSNOTARY_HOST=localhost
