Data exchange, proof attached

Cross-agency and cross-border data sharing where every payload carries a zero-knowledge proof — verify the data is valid without exposing it.

What it does

What it does.

Cross-agency and cross-border data exchange.

Every payload carries its own zero-knowledge proof.

Policy-bound sharing — purpose limitation enforced in code.

Settles over the neutral network with privacy preserved.

How it stays private

The receiving agency verifies that a payload satisfies a policy without seeing the underlying record — the data is checked, not copied.

Verify a claim, never reveal the data.
