Systems and methods described herein are directed to associating a distributed ledger identity of a user with a centralized identity of the user, and generating a verifiable claim including a reference to the user's centralized identity. In some implementations, a method includes: proving a claim using a distributed ledger identity; requesting that a server system create an attestation to the claim proven using the distributed ledger identity that includes a centralized identity of a user, authenticating the centralized identity at an authentication server; and receiving a confirmation message from the server system that a verifiable claim including the user's centralized identity has been created.
