CAIN-42 MCPGateThe niche: long-lived records and post-quantum readiness
Organisations keeping signed records for years: finance, legal, government suppliers, and anyone asked about post-quantum plans.
Why this niche exists now
- NIST published its first post-quantum signature standards in 2024.
- Government and finance buyers increasingly ask vendors about post-quantum readiness.
What people use today, and where it falls short
| What teams do today | Where it falls short |
|---|---|
| Classical signatures only | May be forgeable in the long term. |
| Wait | Records signed today stay signed the old way. |
What makes PQC Hybrid Signing different
- Hybrid: both must verify.
- Uses the NIST standard (FIPS 204).
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Do not quote market-size statistics on a call.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:
- How long must your signed records stay trustworthy?
- Has a buyer asked about post-quantum plans?
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.

Sell it together with
Buyers rarely have just one problem. When this product fits, these often fit too:
| Product | Why it goes together |
|---|---|
| Quorum-QaaS (4-region PBFT) | notarize records |
| Signed decision receipts | signed decisions |
| Offline verifiers (NULLIUS) | check signatures offline |
Rule: open with one product. Mention a second only after the first is agreed.
