Abstract
A communication system configured to provide blockchain-driven certification of iterative electronic communications such as e-mail-based communications. The system provides blockchain-driven certification by storing the hash of an e-mail thread in a blockchain each time the message or its elements are modified. This allows the system to verify whether or not the thread has been tampered with since it was last modified, when the last verified message was added to the thread. The system creates a baseline that is used towards creating trust certificates ensuring the recipients of such iterative electronic communications that the message has not been breached during its iterations that are shared between two or more parties, e.g., communications participants including senders and recipients.
