A transport stack may control identity information that may be owned by a user. An information record of the identity information may be stored on a distributed ledger. Transactors may request a viewing-share for the identity information to support transactions with the user. The transport stack may generate a grant record when a transactor is provided with a viewing-share of the identity information. The grant record may be stored on the distributed ledger. The distributed ledger may provide a verifiable record of the identity information content and history of viewing-share grants.
