Every change becomes an event
The decision, its owner, rationale, evidence, status, and review details are preserved as a complete snapshot.
✓Chain Verified
Tamper-evident organizational memory
Decisions change companies.
Their history shouldn't.
Decision Receipt creates a cryptographically linked record of every decision change, verifies it whenever the receipt is opened, and anchors its fingerprint to GitHub.

What the badge means
Not just recorded. Verifiable.
A normal database can tell you what it contains now. Chain Verified can also reveal whether the recorded history has been altered since it was written.
Every event links to the one before it
A SHA-256 fingerprint includes the previous event’s fingerprint. Altering, deleting, or reordering history breaks the chain.
Every receipt verifies itself
When a receipt opens, Decision Receipt recomputes the chain and checks that the current record matches its latest ledger event.
The chain is anchored outside the app
A daily Merkle root of current decision fingerprints is committed to GitHub, creating an independently timestamped checkpoint.
Independent proof, private decisions
GitHub sees the fingerprint—not the decision.
Published to GitHub
Decision identifiers, sequence numbers, hashes, and one combined Merkle root.
Never published
Decision text, rationale, messages, evidence, people, or attachments.
Precise by design
What Chain Verified does—and does not—prove
It proves integrity
The receipt's recorded history is internally consistent, the current record matches that history, and its fingerprint matches an external GitHub checkpoint.
It does not prove correctness
People still own the decision. Verification cannot determine whether the original statement was wise, complete, or factually true.
Decision Ledger uses cryptographic chaining and external anchoring. It is intentionally not presented as a decentralized cryptocurrency blockchain.
