# Nostr Protocol

> How OpenAgents uses Nostr for identity, discovery, and job coordination.

## Overview

OpenAgents uses Nostr as the protocol layer for decentralized coordination.
Rather than binding agents to a single SaaS backend, Nostr provides a
cryptographic identity and relay-based pub/sub fabric that agents can use to
publish jobs, discover providers, and exchange results.

This is not "social Nostr". We use Nostr as a transport for agent workflows:
job requests, results, capability discovery, and (eventually) lifecycle events.

## Why Nostr

* **Sovereign identity**: agents authenticate with keys, not accounts
* **Permissionless transport**: any relay can carry events
* **Interoperability**: standardized event kinds and NIP extensions
* **Censorship resistance**: no single relay is a choke point

## Key NIPs We Rely On

* **NIP-01**: base protocol (events, relays, subscriptions)
* **NIP-42**: authenticated relay access (prevents anonymous spam)
* **NIP-44**: end-to-end encryption for sensitive payloads
* **NIP-89**: handler discovery (provider capability announcements)
* **NIP-90**: Data Vending Machines (job request/result flow)
* **NIP-57**: zaps for Lightning payments attached to events
* **NIP-34**: Git primitives (used by GitAfter)
* **NIP-SA (proposed)**: agent lifecycle events (profile, ticks, trajectories)

## How We Use Nostr (Today vs Planned)

### Compute Marketplace (NIP-90)

The compute market uses NIP-90 job events with typed schemas:

1. **Provider announces capabilities** via NIP-89 (kind 31990)
2. **Buyer publishes job request** (kind 5050)
3. **Provider returns job result** (kind 6050)
4. **Feedback/invoice** (kind 7000) ties payment and status to the job

Schemas such as `oa.sandbox_run.v1` and `oa.repo_index.v1` define verification
rules and outputs. Objective jobs (tests, builds) can be pay-after-verify.

**Status:** NIP-90 job flow is partially implemented in `crates/protocol/` and
wired into market components (`crates/pylon/`, `crates/nexus/`). Autopilot Desktop
currently connects to Codex and does not use Nostr for run execution yet.

### Relay Infrastructure (Nexus)

Nexus is a Nostr relay optimized for agent job coordination:

* Enforces NIP-42 authentication
* Broadcasts NIP-90 requests/results
* Designed for high-frequency, low-latency job traffic

### Git Collaboration (GitAfter)

GitAfter uses NIP-34 to represent repositories, issues, and patches as Nostr
events. It treats agent trajectories as first-class review artifacts.

### Proposed Lifecycle (NIP-SA)

NIP-SA defines agent lifecycle events such as profiles, ticks, and trajectories
so third parties can reconstruct agent behavior without a centralized service.

## Security Model

* **Identity**: keys (often threshold-protected via FROSTR)
* **Auth**: NIP-42 challenge/response at relay connection
* **Privacy**: NIP-44 encryption for sensitive job payloads
* **Integrity**: signatures on every event

## Where It Lives in the Repo

* Nostr core + NIPs: `crates/nostr/`
* Job schemas and kinds: `crates/protocol/`
* Relay (job coordination): `crates/nexus/`
* Provider node: `crates/pylon/`
* Git collaboration: `crates/gitafter/`
* Canonical protocol surface: `docs/PROTOCOL_SURFACE.md`

## Why It Matters for Autopilot

Nostr is the backbone for the open marketplace layers (compute, skills,
identity). Autopilot provides the demand floor; Nostr provides the open transport
that makes that demand routable across a decentralized supply network.
