Proof, Stamp, Verify.

A movement for verifiable digital proof

Trust less.
Prove more.

ProofStamp helps people and businesses make important digital claims easier to verify – without exposing the underlying private data.


◎ Public education

Plain-language guides that explain hashes, timestamps, privacy, verification, and the limits of digital proof.

◇ Open principles

Encouraging independent verification, interoperable proof formats, honest claims, and privacy-conscious design.

↗ Practical experiments

Working prototypes and partner pilots that turn cryptographic infrastructure into understandable trust workflows.

$+ Business onboarding

Helping teams identify where proof trails can reduce uncertainty, disputes, and audit friction..

Lost trust has a cost🍁

Canadians reported more than $704 million in fraud losses in 202 – —and authorities estimate that only 5–10% of fraud is reported.

– PRINCIPLES

Strong proof starts with honest design.

Private by default

Keep original files off-chain and hash locally.

Independently verifiable

A proof should remain checkable without trusting one company or interface.

No crypto friction

Normal users should see a clear proof receipt—not wallets, gas, nodes, or jargon.

VERRIFY – TRUST – TRANSACT

What people say

We’re moving from “find the fake” to “provenance by
default.”
Trust is no longer something you verify after the fact. Trust is
cryptographically verifiable, privacy preserving, and built into the architecture of Web3 itself.

    Trust begins where certainty ends. We trust that the person we are speaking with is who they claim to be. We trust that a document has not been quietly altered. We trust that a photograph represents something that happened. We trust that a company will deliver, a bank will protect our money, and an institution…
