Methods and systems of providing verification of the identity of a digital entity using a centralized or distributed ledger

摘要

Providing verification of the identity of a digital entity may include including receiving information and a public key of the digital entity, the information having been previously attested to in an attestation transaction stored within a centralized or distributed ledger at an attestation address, the centralized or distributed ledger providing a record of transactions. The system may derive an attestation address using the information and the public key of the digital entity. The system may verify the existence of the attestation transaction at the attestation address in the centralized or distributed ledger and verify that the attestation transaction has not been revoked. The processor associated with the user may receive a cryptographic challenge nonce signed by the digital entity's private key; and may verify the digital entity's identity with the cryptographic challenge nonce signed by the digital entity's key.
