Before you ask

Eight things you're probably wondering.

Every answer below links to a live proof on this site. No marketing prose, no waiting for a call, no email gate.

You ask
Is this real?
The answer
You just saw it work on your own file. The receipt is real. Verify it on Bitcoin right now.
Verify on Bitcoin
You ask
What if Bonis Systems goes out of business?
The answer
Your anchors live on Bitcoin, not our server. The verify script runs air-gapped. We could vanish tomorrow — your proof still holds.

How much does it cost?

You ask
Will this slow my system down?
The answer
Measured p50 anchor latency: 158 ms. Async by design, failure-safe, off your critical path. If Knox is unreachable, your primary operation still completes.
