Product · Proof of Priority

Timestamped evidence of digital priority.

Proof of Priority documents the state of a digital asset at a specific point in time — beweissicher, hash-sealed and verifiable. Not a backup. Not a screenshot. A digital priority record.

The Problem

The question is not whether you have a copy.

In any dispute over digital priority — design, content, product page, campaign — the relevant question is: can you later prove that this asset already existed at this point in time?

Backups, archives and screenshots do not answer that question. A documented priority record does.

The Solution

A documented state of a digital asset at a specific point in time.

Proof of Priority captures the asset, seals it with a cryptographic hash and a verifiable timestamp, and stores it as part of a chain of custody — ready to be referenced years later.

How it works

One shared Evidence Engine.

  1. 01

    Baseline

    Initial state of every channel is captured.

  2. 02

    Snapshots

    Continuous, scheduled capture per channel.

  3. 03

    Delta Analysis

    Structural changes are detected over time.

  4. 04

    Evidence Chain

    All events are hash-sealed into a verifiable chain.

Evidence Timeline

A chronological record — not a folder of screenshots.

Every captured event is filed onto a single, verifiable timeline. Every entry carries a timestamp, a SHA-256 hash and a link to the underlying snapshot.

Architecture

Built on the shared Evidence Engine.

Baseline · Snapshots · Delta Analysis · Evidence Chain — the same architecture that powers every EvidenceFirst product.

Evidence Report

A self-contained, legally usable document.

  • Asset identity and URL
  • Captured state (HTML, screenshot, PDF)
  • SHA-256 hash and verifiable timestamp
  • Chain-of-custody record

Preserve priority. Before it is challenged.

A digital priority record is created once and stands for years.
