How UVRN Works

UVRN — the Universal Verification Receipt Network — is an open protocol that measures whether independent sources agree on a claim. It gathers evidence, scores how well the sources corroborate one another, and issues a tamper-evident receipt of what it found. Receipts over vibes.

Every claim is scored once, with a formula defined once in the protocol core and never redefined:

• Completeness — how much of the input evidence yielded usable signal.
• Parity — how closely the independent sources agree once normalized.
• Freshness — how recent the corroborating evidence is.

The Delta-Engine runs a consensus check across sources and returns a continuous parity signal plus a verdict. A high-agreement result is consensus; meaningful divergence is indeterminate — not an error, but a real signal that sources differ in substance or emphasis. Parity works as a leading indicator: a score drifting downward across batches warns of degradation before a claim fails outright.

Each run emits a cryptographic receipt — a hash, the score, and the verdict — that anyone can verify without calling the issuer. Public receipts are searchable on the registry ledger.

UVRN measures whether your sources agree with each other — not whether they are correct. It helps you find and track correlations and generates a receipt of its findings. Final trust of any output rests with the user. UVRN is in active development (Alpha).
