Core concepts

Learn the fundamentals of the PEAC Protocol.

Receipts

Signed JWS tokens with Ed25519 signatures. The core proof artifact.

Policy (peac.txt)

Machine-readable terms at /.well-known/peac.txt. Discoverable by agents.

Verification

Offline, deterministic. Zero network calls to the issuer.

Evidence bundles

Portable peac-bundle/0.1 archives for audits, disputes, and incident review.

Protocol Scope

Access, Attribution, Commerce, Consent, Compliance, Privacy, Provenance, Safety, Identity, Purpose.

Wire format

peac-receipt/0.1 (stable) + interaction-record+jwt (Wire 0.2 preview). Ed25519 + compact JWS.

Guides

Step-by-step integration guides for common use cases.

Express middleware

Add automatic receipt issuance to Express.js. One middleware, every response gets a signed header.

MCP server

5 MCP tools: verify, inspect, decode, issue, bundle. AI agents verify receipts natively.

OpenClaw capture

One-call setup with activate(). Spool store, deduplication, structured export counters.

Payment rails

x402, Stripe, Razorpay, card networks. Attach payment evidence to receipts.

---

Architecture

Package layering

7-layer dependency model. Dependencies flow down only.

Kernel-first design

JSON specs drive implementation. Codegen, not convention.

Error codes

11 categories, RFC 9457 format. Every failure is structured.
