Running a **Nostr node** typically means running a **Nostr relay**, which is a server that stores and forwards messages (called “events”) between Nostr clients. It's much simpler than running a full Bitcoin node or a Mastodon server — but you still need to understand a few key components.
Here’s what’s involved:
---
### ✅ 1. **Choose a Relay Server Implementation**
Popular open-source relay implementations:
* `nostr-rs-relay` (Rust, performant, widely used)
* `Nostream` (TypeScript/Node.js, extensible)
* `go-nostr` (Go, easy to set up)
---
### ✅ 2. **System Requirements**
* **Lightweight:** A small VPS or even a Raspberry Pi is usually enough
* **Requirements:**
* Linux (Ubuntu/Debian preferred)
* 1 CPU, 512MB+ RAM
* 10GB+ disk (depending on storage strategy)
* Public IP or accessible hostname
* Open port (default is 7777 or 443 if reverse proxy)
---
### ✅ 3. **Installation & Setup**
Example: Using `nostr-rs-relay`
```bash
git clone https://github.com/scsibug/nostr-rs-relay.git
cd nostr-rs-relay
cargo build --release
./target/release/nostr-rs-relay
```
Or use a prebuilt Docker image.
---
### ✅ 4. **Configuration**
You can configure:
* Port (default 7777)
* Database (SQLite or Postgres)
* Max events stored / time retention
* Authorization (public or private)
* Relay policy (e.g. NIP-11 support, whitelisting, event kinds)
---
### ✅ 5. **(Optional) Set Up a Reverse Proxy**
If you want your relay available over HTTPS:
* Use **Nginx** or **Caddy** with **Let's Encrypt** for TLS
* Forward requests from `wss://yourdomain.com` to the relay
---
### ✅ 6. **Announce Your Relay**
* Include your relay URL in your Nostr profile
* Submit it to relay lists (like on [nostr.watch](https://nostr.watch))
* Consider setting `read` and `write` permissions or rate limits
---
### ✅ 7. **Maintain It**
* Regularly update your relay software
* Monitor uptime and performance (use `htop`, `journalctl`, etc.)
* Optionally prune old events or set DB size limits
---
### 🚀 Bonus Features You Can Add
* NIP-05 verification
* Paid relay access (Zap splits, LNURL-pay)
* Logging & dashboards (Grafana + Prometheus)
* Peer relay federation (less common for now)
