Abstract
Systems and methods for identity verification to provide access to restricted goods or services. A first device may receive, from a second device operated on behalf of a user, a first request to purchase a restricted good or service. The first device may transmit, to the second device responsive to the first request, a second request comprising an identification of information of the user, and an identification of validation system; and may receive the requested information of the user. The first device may generate an attestation key comprising a hash of the requested information of the user and the identification of the validation system; and may determine that a record in a centralized or distributed ledger at an address corresponding to the attestation key is associated with a non-zero transaction value. Responsive to the determination, the first device may provide the restricted good or service to the user.
