Abstract: An identity system is provided that may include an attestation service that is configured to communicate with a user computer device and a blockchain platform, and create a blockchain account for the attestation service on the blockchain platform, the account having an associated backend blockchain identity application. The attestation service may further be configured to determine that a user of the user computing device owns a user blockchain account by obtaining a signed message of the user. The signed message may include a user access token from the user of the user computer device and a blockchain address of the user to associate with the access token, the user access token having been generated by a trusted identity provider service. The attestation service may further be configured to identify one or more identity claims associated with the token, and store the identity claim for future presentation to a third party.
