Protocol Features

Built for verification, not validation

Verifiable Receipts

Every claim gets a cryptographic receipt. The proof speaks for itself.

Portable Trust

Proof travels with your data. Verify anywhere, anytime.

Slop-Proof

Built to resist manipulation. Protocol-grade integrity.

UVRN Protocol

UVRN

Portable proof for the open web.

UVRN is the lightweight verification protocol that powers verifiable receipts—receipts that flow freely until you decide to block (canonize) them.

v5 · liveUVRN Packages v5 is the canonical 33-package protocol generation — all @uvrn/* packages live on npm (spine 5.0.0; mcp 5.0.1; store-sqlite 5.0.2; visual/chart-memory/track-record 5.0.1). The engine measures whether independent evidence about a claim agrees, disagrees, conflicts, or shows early potential — provably.

Core Idea

“Proof that flows. Block it when it matters.”

UVRN replaces heavy ledgers with tiny receipts: signed JSON records that prove who did what, when, and with what result.

Each receipt can stay loose (mutable, portable) or become blocked (canonical, permanent).

Tag Examples

Tags act like open-graph hashtags for proof context. They help index receipts across apps, agents, and people.

Tag	Meaning	Typical Use
#drvc3	DRVC3 certificate / protocol	Compliance, generic proof, schema version
#canonized	Finalized / blocked receipt	Locked record, NFT seal, or audit log
#uvrn	Universal Verification Receipt Network	Cross-registry sync
#proof	Generic evidence emission	Generic verification events
#vscore	Confidence-score event	Quality metrics / analytics
#ai-action	AI-initiated proof	Model run, agent act, automation
#human-sign	Human-signed receipt	Wallet, e-mail, or identity signature
#group-seal	Collective canonization	1155/721 supporter seals
#loglog	Human-readable twin entry	Sync to Hermes DevChronicle
#replayable	Contains replay instructions	Used by AI automations
#looseproof	Temporary verification	Draft, pre-publication proof

Each tag can appear in the receipt metadata:

"tags": ["#uvrn", "#drvc3", "#canonized"]

UVRN Protocol Outline

1. Receipt Structure — DRVC3 Schema

{
  "receipt_id": "abc123",
  "issuer": "app.example.com",
  "event": "content.publish",
  "timestamp": "2025-10-06T21:00Z",
  "integrity": {
    "hash_algorithm": "sha256",
    "hash": "sha256:…",
    "signature_method": "eip191",
    "signature": "0x…",
    "signer_address": "0xA9F1…"
  },
  "validation": { "v_score": 92, "checks": {} },
  "block_state": "loose",
  "certificate": "DRVC3 v1.0",
  "replay_instructions": {"service": "app.launcher", "params": {"id": "42"}},
  "tags": ["#uvrn", "#drvc3", "#replayable"]
}

2. Lifecycle (TVC Loop)

TEST → VALIDATE → CANONIZE

Test System or user emits a loose receipt.
Validate Cross-checks parity, completeness, freshness → V-Score.
Canonize (“Block”) – Optionally lock the proof; write to the Canon Log; issue DRVC3 certificate.

3. Endpoints

Method	Endpoint	Purpose
POST	/api/v1/receipts	Create / emit proof
GET	/api/v1/receipts/:id	Public verification
POST	/api/v1/canonize/:id	Finalize proof
GET	/api/v1/search?tag=#uvrn	Discovery / analytics

Delta Engine API (@uvrn/api)

Method	Endpoint	Purpose
POST	/api/v1/delta/run	Execute engine on bundle (returns receipt)
POST	/api/v1/delta/validate	Validate bundle schema
POST	/api/v1/delta/verify	Verify receipt (replay / hash)

4. Integration Pattern

Layer	Example
Apps	Substack, LK Hub, Figma plug-in, etc.
Auth	Wallet / OAuth signature
Network	Universal Verification Receipt Network (UVRN, open-source, neutral)
Optional On-chain Anchor	Ethereum / EVM hash reference

5. Principles

Open by default – No proprietary ledger.
Minimal and verifiable – Store hashes, not content.
Human + Machine friendly – Readable + executable.
Selective immutability – Block only what must endure.
Ethical proof design – Privacy-preserving verification.

Disclaimer: UVRN is in Alpha testing. The engine measures whether your sources agree with each other — not whether they're correct. Final trust of output rests with the user. Use at your own discretion. Have fun.

*UVRN makes no claims to "truth", the "verification" is the output of math — it is up to any user to decide if claim is actually "true" — Research and testing are absolutely recommended per use case and individual system!!
