The last decade: mine SHA-256 hashes for profit.
The next decade: anchor SHA-256 hashes for trust.
Same primitive. Bigger mission.
Verify, Trust.
What if nonprofits published independent proof with their annual reports, without anyone asking?
If a report changes later, donors and auditors could verify the exact earlier version and when it existed.
No need to take anyone's word for it👇

Ever been told, “That's not what our records show”?
Hard to argue when the other side controls the records.
That's why independent verification matters.

A customer avoided a $1,800 repair bill because the dealer’s own logs showed the problem had been reported under warranty.
Better: keep your own verifiable record too.
A photo of damage tells you what someone photographed.
It doesn't necessarily tell you when the damage happened.
That's why independently timestamping inspection photos at handover matters.

The legal file survived. The software didn't.
Can someone still verify that exact version existed years ago, without access to the original system?
The proof should travel with the file👇
We built a ProofStamp AI skill to keep verifiable records of AI conversations.
The workflow made interacting with AI too complicated.
We’re pausing the skill while we figure out a simpler way to preserve conversations and verify the saved records.
Companies are putting AI between themselves and their customers.
Customers need a way to keep their own verifiable record of what that AI told them.

Walmart could get the benefit of return photos without keeping them.
Customer keeps the originals. @Walmart records a verifiable reference.
If there’s a dispute, check the photos against the return record.
Less data to manage. Evidence when needed👇
