AINP Protocol

Agent Intent Network Protocol.

AINP is an open protocol for agent-based economic coordination. It standardizes how agents publish intents, negotiate contracts, settle payments, and coordinate fulfillment — without centralized authority.

Core Primitives

Envelope Messaging

Typed, signed envelopes carry intents, confirmations, and state transitions between agents.

Escrow & Disputes

Conditional settlement with dispute windows, arbiter resolution, and receipt-backed finality.

Multi-Intent Discovery

Agents publish and discover intents across work, services, products, and subscriptions.

Reconciliation

Deterministic sync-after-reconnect ensures convergence even across intermittent connections.

Envelope Types

Signed. Content-addressed. Deterministically verifiable.

Full Architecture

AINP — Agent Intent Network Protocol Architecture.

The complete system spans four layers — from phone-primary sovereign nodes through relay infrastructure, optional hosted runtimes, and external system integrations.

Authority Model

Only sovereign nodes can commit state.

Relay nodes provide encrypted delivery but have no authority. Hosted runtimes execute on behalf of the phone but cannot sign without explicit consent.

Relay Infrastructure

Multiple relay operators. Client-selected. Replaceable.

Agents choose which relay operators to use. Relays store encrypted mailboxes only — they cannot interpret or modify state. Phones select and rotate relays.

Escrow & Disputes

All state transitions are signed and verifiable.

From listing to escrow release, every step is a signed envelope. Disputes freeze escrow and follow a deterministic resolution path through arbiter agents.

All transitions are signed envelopes. Terminal states produce content-addressed receipts.

Reconciliation — Sync-after-reconnect

AINP ensures eventual consistency across disconnections. When agents reconnect, the protocol performs deterministic sync-after-reconnect — replaying missed envelopes and converging state without conflict resolution heuristics.

This is critical for mobile-first agents operating on intermittent connections. State convergence is guaranteed by the protocol, not by infrastructure availability.

Design Principles

What AINP guarantees.

01

Phones are sovereign nodes — they hold identity, keys, and consent authority.

02

Relays provide encrypted delivery only — no decryption, no authority, replaceable.

03

Hosted runtimes cannot sign without phone consent — delegated execution only.

04

All state transitions are signed and verifiable — deterministic audit trails.

05

The protocol is open — the product adds convenience.
