An immutable ledger for legal evidence, and a tool whose only job is proving it wasn’t touched

Description and use

Opencomplai provides immutable evidence storage and an independent verifier to ensure audit logs cannot be tampered with after creation.

Problem

How to prove that a compliance evidence store was not altered after being written

Outcome

The verifier independently confirms that the evidence chain has not been altered, providing stronger assurance than editable audit tables

Workflow

• 1. Store evidence as content‑addressed immutable artifacts in evidence‑vault
• 2. Record each artifact’s hash as its address
• 3. Use tools/verify‑ledger to walk the evidence chain
• 4. Verify that each record’s hash matches its content and that the chain is unbroken
• 5. Run the verifier against the raw ledger to prove integrity

Evidence

Opencomplai's evidence-vault service stores every piece of compliance evidence, scan results, eval reports, sign-offs, as content-addressed immutable artifacts.

Source

An entry's address is a hash of its content. Change the content later and you get a different address, not a changed record.

Source

A standalone verifier. It walks the evidence chain and confirms nothing was tampered with, and it doesn't depend on the service that wrote it.
