# FIPS: Free Internetworking Peering System
A distributed, decentralized network routing protocol for mesh nodes
connecting over arbitrary transports.
> **Status: Experimental / Pre-release**
>
> FIPS is under active development. The protocol and APIs are not stable.
> Expect breaking changes.
## Overview
FIPS is a self-organizing mesh network that operates natively over a variety
of physical and logical media — local area networks, Bluetooth, serial links,
radio, or the existing internet as an overlay. Nodes generate their own
identities, discover each other, and route traffic without any central
authority or global topology knowledge.
FIPS uses Nostr keypairs (secp256k1/schnorr) as native node identities,
making every Nostr user a potential network participant. Nodes address each
other by npub, and the same cryptographic identity used in the Nostr ecosystem
serves as both the routing address and the basis for end-to-end encrypted
sessions across the mesh.
## Features
- **Self-organizing mesh routing** — spanning tree coordinates and bloom
filter candidate selection, no global routing tables
- **Multi-transport** — UDP/IP overlay today; designed for Ethernet,
Bluetooth, serial, radio, and Tor
- **Noise encryption** — hop-by-hop link encryption plus independent
end-to-end session encryption
- **Nostr-native identity** — secp256k1 keypairs as node addresses, no
registration or central authority
- **IPv6 adaptation** — TUN interface maps npubs to fd00::/8 addresses for
unmodified IP applications
- **Metrics Measurement Protocol** — per-link RTT, loss, jitter, and goodput
measurement
- **Zero configuration** — sensible defaults; a node can run with no config
file
## Quick Start
### Requirements
- Rust 1.85+ (edition 2024)
- Linux (TUN interface requires `CAP_NET_ADMIN` or root)
### Build
```
git clone https://github.com/jmcorgan/fips.git
cd fips
cargo build --release
```
### Run
```
# With default configuration (ephemeral identity, default ports):
sudo ./target/release/fips
# With a configuration file:
sudo ./target/release/fips -c fips.yaml
```
See [docs/design/fips-configuration.md](docs/design/fips-configuration.md) for
the full configuration reference.
### Multi-node Testing
See [testing/](testing/) for Docker-based integration test harnesses including
static topology tests and stochastic chaos simulation.
## Documentation
Protocol design documentation is in [docs/design/](docs/design/), organized as
a layered protocol specification. Start with
[fips-intro.md](docs/design/fips-intro.md) for the full protocol overview.
