CAIN-42 MCPGateThe niche: tamper-evident records for AI systems
Anyone who must later prove that their AI records were not altered: AI vendors answering customers, teams preparing for an audit or a dispute, and builders of agent platforms who want their logs to be believable. It is the trust layer under many of the other products.
Why this niche exists now
- AI agents act on their own, so disputes about "what really happened" are becoming common.
- Ordinary logs are controlled by the party being questioned, so they convince nobody in a dispute.
- Buyers and auditors increasingly ask for evidence that records were not changed.
- Blockchains solve this but are slow, costly and carry a reputation many businesses avoid.
What people use today, and where it falls short
| What teams do today | Where it falls short |
|---|---|
| Keep logs on your own server | You can edit them, so a sceptic will assume you did. |
| A single timestamping service | One operator; if it errs or is compromised, nobody notices. |
| A public blockchain | Slow, fees, and a reputation problem for many buyers. |
| A notary or lawyer | Fine for one document, impossible for thousands of logs a day. |
What makes Quorum-QaaS (4-region PBFT) different
- Byzantine fault tolerant: one faulty or lying server cannot fake a receipt.
- Content never leaves the client: only a fingerprint is sent.
- The receipt is checked offline by a small checker with no CAIN code.
- Pinned keys: the checker refuses a receipt from a cluster you did not pin.
How big is the opportunity?
Do not quote market-size statistics on a call. Most published figures are surveys or vendor estimates, and a smart buyer will ask for the source. Size the opportunity per prospect instead, with these questions:
- Have you ever had to prove your logs were not changed?
- Who asks you for evidence about your AI system: customers, auditors, insurers, lawyers?
- How many records a day would you want sealed?
- Do you already keep AI decision logs?
If the honest answers are "no" or "not yet", they are not a buyer today. Note it and move on; that is good selling, not failure.

Quorum-QaaS gets a record confirmed by four servers in four regions, so nobody, including us, can quietly change it later.
Practise saying this out loud until you can do it without reading. Then say it in your own words.

Sell it together with
Buyers rarely have just one problem. When this product fits, these often fit too:
| Product | Why it goes together |
|---|---|
| Black Box flight recorder | notarize the recording's seal |
| Offline verifiers (NULLIUS) | how receipts are checked |
| Verify-yourself page | live proof the cluster works |
Rule: open with one product. Mention a second only after the first is agreed.
