Abstract
A method of verifying telecommunications messaging traffic between two entities and monetizing the verified traffic. A receiving entity receives a message from a sending entity. The message includes a hash value computed by the sending entity based on the content of the message. The hash value is encrypted using a private key of the sending entity. The receiving entity identifies, within a blockchain, a Decentralized Identifier (DID) associated with the sending entity, resolves the DID into a DID document, and retrieves therefrom a public key associated with the sending entity. The receiving entity decrypts the hash value provided by the sending entity using the retrieved public key. The receiving entity independently computes a hash value based on the message content and compares the computed hash value against the decrypted hash value. If the hash values match, the message is verified and routed to its target recipient.
