RLTP — Real Life Trust Protocol

Specifications, schemas, and test vectors for a decentralized trust protocol rooted in encounters between people: two humans meet, recognize each other, and record that recognition as verifiable credentials. Trust is anchored in real meetings rather than in a certifying institution. Cryptography proves freshness and authorship; only a human can witness a human.

Published by the Real Life Organisation. The protocol grew out of the deployed Web of Trust app, whose ceremony flows have been exercised at festivals and community gatherings since 2026.

What is in this repository

Path Content
spec/encounter-layer.md RLTP Encounter Layer — how two people establish, record, and maintain mutual recognition: the one registered ceremony (encounter-scan, with a connected path and an offline path and free switching between them), contact cards, challenges, the own-challenge state model, the enactment binding, encounter credentials, edges
spec/delivery-contract.md RLTP Delivery Contract — how documents travel: private Trust Task types (encounter-bundle, delivery-ack, encounter-credential-delivery), the sealed envelope, staged dispositions, delivery promises
schemas/ Normative JSON Schemas for every wire artifact
contexts/ The pinned RLTP JSON-LD context
vectors/seal.json Deterministic seal test vector — implementations MUST reproduce it byte-for-byte
interop/ceremonies/ RLTP ceremonies expressed in the ToIP DTGWG ceremony-definition format
simulator/ Interactive browser simulator of the full ceremony (both paths, fault injections) + a Node reference engine
scripts/validate.mjs Publication checks: schema compilation, vector recomputation, and conformance fixtures that MUST fail

Status

Both documents are Editor’s Drafts, developed through an adversarial convergence process: each casting is reviewed by an independent adversarial reviewer, findings are triaged, and the document is fully recast — never patched — until a casting pair is judged blocker-free and compatibly implementable. The current pair (Encounter 0.19 · Delivery Contract 0.17) has reached that criterion — its final review round returned no findings. Notable in this pair: the two earlier ceremonies are unified into one with a connected and an offline path; a formally complete own-challenge state model (open / recorded / unknown) with a monotone aging latch makes every acceptance branch deterministic under challenge rotation, races, restarts, and backward-moving clocks; and sent cards carry boundTo so the optical receiver always knows which of its own challenges an enactment answers.

The Identity layer (the interim securing profile in Encounter §2.3 will move there), the Access layer, and the Data layer are in earlier stages and not yet published here.

Alignment with the ToIP DTGWG

RLTP deliberately aligns with the emerging ToIP Decentralized Trust Graph work where the two effort meet:

Where RLTP differs, it differs deliberately and says why in the specifications themselves: participant recognition rather than third-party witness, stable anchors rather than pairwise identifiers, and honestly stated correlation properties.
