System and method for autonomous mapping of enterprise identity

A method comprising:

• retrieving a target public key associated with a target party, wherein retrieving the target public key comprises utilizing a decentralized identifier associated with the target party and a requesting party;
• generating a secret off-chain based on, at least in part, the target public key associated with the target party and a private key associated with the requesting party;
• generating a payload off-chain configured to be used for establishing a direct private channel of communication between the requesting party and the target party for validating each party's identity, wherein the payload comprises an authentication token with a limited time to live (TTL);
• encrypting the payload off-chain using the secret;
• broadcasting a message comprising the payload to a public blockchain;
• determining whether an intended recipient, as represented by an internal identifier within the requesting party's system of record, will be able to provide the authentication token to the requesting party in order to establish that the intended recipient is the target party represented by the decentralized identifier used to retrieve the target party's public key;
• and
• mapping the internal identifier associated with the system of record connected to the requesting party to the decentralized identifier over the direct private channel of communication, wherein the mapping of the internal identifier comprises a conversion associated with a public key of the requesting party and a private key of the target party.
