Prove · Verifiable receipts
Revoluzen Evidence
Signed, independently verifiable receipts for what ran. Hand someone the receipt and the public key and they can check it themselves — offline, with no access to our software, our servers or your systems.

A receipt, not a log line
A log says a system believes something happened. A signed verifiable execution record lets a third party confirm it, without trusting the system that produced it.
- 01Covers inputs, outputs, code version and result for a run
- 02Signed with Ed25519 at the moment of execution
- 03Tamper-evident: any change to the record invalidates the signature
Verification that does not need us
This is the part that matters. If verifying a receipt required our server, the proof would only be as durable as our company. It does not.
- 01Verification needs the receipt and a public key — nothing else
- 02The verifier is a standalone open-source tool
- 03Works offline, in an air-gapped environment, years later
- 04Proof outlives the subscription, the vendor and the deployment
What it is good for
The situations where 'trust me, it ran' has a real cost.
- 01Regulatory submissions: send the figure and the receipt together
- 02Processing on behalf of clients: show exactly which records a job touched
- 03Disputes: settle what ran from signed evidence, not expired logs
- 04Internal controls: evidence that a control actually executed
The details, in one table
The facts a technical evaluator checks first, without having to read a datasheet.

Open source
The verifier stands alone
Revoluzen Evidence ships as its own open-source package, separate from Flow, so an auditor can verify a receipt without installing the orchestrator at all.
Open-source commitmentsWhat this does not do yet
You would find these out eventually. Finding them out now is cheaper for both of us.
A receipt proves what the executing system recorded and signed. It is strong evidence of execution; it is not a proof that your business logic was correct.
Key custody is your responsibility. If you lose the private key, you cannot sign new receipts; if you leak it, the signature stops meaning anything.
Receipts are most useful when they are retained deliberately. They are evidence, which means somebody has to keep them.
