Participant Relationship Protocol

Communication around people

Participant Relationship Protocol

Choose who you connect with. Keep your identity independent of your connectivity provider. PRP explores a different foundation for communication: the relationships between participants.

Start here · Introduction

Meet PRP

A short introduction to PRP: communication built around participants and relationships, identities independent of connectivity providers, and household devices without mandatory manufacturer accounts.

Illustrated video with partial animation.

The idea

People and relationships come first.

PRP explores communication built around who you choose to connect with, rather than the network you happen to use. Its design separates identities from connectivity providers and aims to keep relationships useful as connections change.

The project is in the standardization stage. The films explain its ideas; they are not guarantees of availability or interoperability.

Roadmap

From candidate architecture to open interoperability.

The roadmap records technical gates, not promised dates. Work controlled by the project is distinguished from assignments and standards decisions made by external communities.

01 Active

PRP core

Stabilize the architecture, wire protocol, registries, security model, and version migration rules.

  1. Candidate architecture and working drafts
  2. Normative vectors and conformance suite
  3. Independent implementation interoperability
02 Active

IETF standardization

Develop Internet-Drafts and take the work through open technical and community review.

  1. Architecture Internet-Draft -00 published
  2. IPR, contribution, and registry governance
  3. Community discussion and draft revisions
  4. Working Group, DISPATCH, or sponsored path
  5. Possible RFC following IETF consensus
  6. Proposed PRP DNS resource record — revision pending
  7. IANA registration of the prp URI scheme — planned
03 Conditional

Carrier assignments

Request globally scarce identifiers only after each carrier binding is stable and independently justified.

  1. IANA service name and UDP user port
  2. IEEE EtherType for PRP over Ethernet
  3. Bluetooth assignment only if a future profile requires it
04 Independent

Ethernet discovery

Discovery is a carrier-side protocol, not part of the PRP wire protocol or a prerequisite for every deployment.

  1. Stabilize its own framing and lifecycle
  2. Preserve independent versioning and security
  3. Request its own EtherType if publicly deployed
05 Submitted / planned

Regulatory & data protection assessment

ANATEL consultation submitted; ANPD assessment planned.

  1. ANATEL consultation submitted

    A consultation has been submitted to ANATEL about identifier-retention obligations in native PRP communications without participant IP addresses.

    SEI process: 53500.146906/2026-42.

    Follow the process in ANATEL’s public SEI search by entering the process number in the “Nº SEI” field. The search requires JavaScript.

    This filing does not constitute regulatory approval or a compliance finding. PRP is in the standardization stage.
