Integrity Layer

SHA256 snapshot verification

Every published market-state snapshot can be fingerprinted and independently validated.

Verification objective

The verification model prevents silent edits to historical signal context. A snapshot payload and its SHA256 digest are paired at publication time. Any later content mutation changes the digest and fails validation.

  • Deters hindsight performance rewriting.
  • Supports reproducible research workflows.
  • Improves accountability for signal publications.

Verification flow

  1. Download or copy the published snapshot payload exactly as posted.
  2. Hash the payload with SHA256 using a local tool.
  3. Compare your output digest with the published digest.
  4. If digests match, the snapshot integrity is confirmed.

Linux/macOS

sha256sum snapshot.json

Windows PowerShell

Get-FileHash .\snapshot.json -Algorithm SHA256

Canonicalization note

Hashes are deterministic only when the payload bytes are identical. If tooling reformats JSON or changes line endings, digest values can diverge. Verification should use the exact canonical snapshot bytes as published by SignalX Intel.
