#+title: Social Protocol Overview
#+filetags: :passepartout:social-protocol:network:dids:

Passepartout Social Protocol is the decentralized identity and communication layer that connects [[id:28c46769-c14b-42aa-ac7a-69d310157f8f][Passepartout]] instances:

- **Self-sovereign identity** via HD key derivation (BIP-44)
- **Encrypted messaging** via DIDComm (agent-to-agent and agent-to-human)
- **Notes** as atomic, content-addressed, signed data units (mapped from Passepartout memory-objects)
- **Relay Network** for censorship-resistant message routing
- **Personal Data Store (PDS)** — the Merkle fact store exposed as a network-addressable service
- **[[id:3c6b0449-a8fb-5b89-b82a-34efb21ef5b5][Compute marketplace]]** where instances offer symbolic engine capacity
- **Contracts and liquid democracy** infrastructure

The PDS is Passepartout's in-process memory — the Merkle tree, the fact store, the memory-objects. Every memory-object already has a SHA-256 hash, which maps directly to the social protocol's CIDv1 content addressing.

Revenue paths from the social protocol:
- [[id:2e390c1d-65f3-5fb3-b898-ac3fc4291ee7][Premium username registry]] — $10M/yr at scale
- [[id:1a2b38df-20ba-58ca-ba55-a072be67bd0d][PDS as a service]] — $18M/yr at scale
- [[id:3c6b0449-a8fb-5b89-b82a-34efb21ef5b5][Compute marketplace]] — venture-scale
- [[id:64708e1f-00e9-4cb7-b44b-ea0b98e5296d][Smart contracts + contract marketplace]] — the kill app
