Abstract: Embodiments described herein are directed to a verifiable identity map that maintains identities and public keys associated with the identities. The map is maintained by a ledger database that provides tamper-resistant/evident capabilities for tables (comprising the map) thereof. For instance, when a materialized view of the database is generated, the database provides a digest representative of a state thereof to computing devices that access the map for the keys. When the database receives a request from a device to access the map, the digest is received along therewith. The database is validated based on the digest to determine whether the database has been tampered with since the provision of the digest. Responsive to a successful validation, the database provides access in accordance with the request. When a key in the map is updated, the database subsequently generates a new digest, which is provided to the computing device.
