Limit disclosure
Design the output around the decision. Share an approved threshold result instead of routinely exchanging complete records.

03 / ZK Validation
Share the answer.
Keep the record.
Zero-knowledge validation for checks that need a fact, not a full personal record. Let a counterparty verify a defined statement using a cryptographic proof.

Ask only what the decision needs
An age-restricted service needs to establish eligibility. A name and a full date of birth reveal more than that decision requires.

Agree on the statement, its inputs and the party responsible for verifying them.
Interactive illustration · Fictional data · No live requests
Less information exchanged to make a decision.
Selective disclosure · Verifiable proofsWHY THIS LAYER
A decision without the dossier.
Make the check explicit
Agree on one statement with the verifier. Define time, thresholds and accepted evidence before choosing a circuit.
Separate responsibilities
Identify who validates source information, who creates the proof and who decides whether to accept it.
TECHNICAL EVALUATION
What must a verifier actually check?
Define the evidence for your pilot before making a production decision.
Source evidence
Identify who validates the original fact and when it expires.
Document the issuer, evidence provenance and freshness requirement.
Statement & circuit
Agree on public inputs, thresholds and an accepted circuit version.
Obtain the circuit specification, verification key and available review materials.
Acceptance
Bind the proof to the intended decision and receiving system.
Test valid, modified, stale and replayed evidence with the intended verifier.
FROM INTEREST TO INTEGRATION
Agree on what the proof means.
Define success for one workflow before expanding the scope.
Plan it with an architect- 01
Define the decision
Write down what the counterparty must learn and what should stay private. Age, ranges and membership are useful starting points.
- 02
Review evidence and circuit
Confirm input provenance, circuit availability, public inputs and verification requirements with the technical team.
- 03
Test with the verifier
Try valid, invalid and stale evidence. Agree on acceptance rules and the operating process before rollout.
