Abstract: The present disclosure may provide methods, systems, and computer-readable instructions for enabling the following operations: generating a secret key based on, at least in part, a target party's public key; encrypting a payload with the secret key, the payload comprising an auth token with a limited time to live (TTL); broadcasting, to a public blockchain, a message comprising the encrypted payload; receiving a request to establish a channel of communication outside of the public blockchain; receiving, with the request, the auth token within the TTL; validating the auth token within the TTL; establishing the channel of communication upon a validation of the auth token; engaging in a data-exchange over the channel of communication; verifying matching properties of the exchanged data with at least one internal system of record; and mapping an internal identifier within the at least one system of record to a decentralized identifier associated with the target party.
