Aspects of the present disclosure are directed to verifying a communication identifier or electronic address using one or more blockchains. Implementations mint non-fungible tokens (NFTs) that correspond to the electronic addresses and/or communication identifiers. A person or company can communicate with third-party entities via the electronic addresses and/or communication identifiers. A given third-party entity can verify that a NFT that corresponds to the specific electronic address and/or communication identifier the given third-party is interfacing with has a corresponding minted NFT. The existence of such a minted NFT verifies that the specific electronic address and/or communication identifier has been registered with a trusted authority. The third-party entity can then safely interact with the electronic address and/or communication identifier once receiving the verification result.

Blockchain based verification of electronic addresses or communication identifiers

Mutual authentication and CSR verification techniques are described in this patent document. When a first person calls a second person, neither of them know that the other person is who he or she says he or she is. After a second person receives the call, the second person can log into a provider portal using a user device. After the second person logs in, the second person can see a verification of the call, can input on the user device a time passcode, or can receive such as passcode from a central system to authenticate the first person. The first person can provide the passcode to the second person. Upon receiving the inputted passcode, the second person can use his or her user device to indicate that the time passcode is correct so that the second person can be authenticated to access the first person's account.
