storing, using a decentralized bot, in persistent storage of a blockchain-associated smart contract, message-specific information comprising a message body and a message identifier, and user-specific information comprising a user identification for an intended recipient of the message;
issuing, through a notification provider, a push notification associated with the message to the intended recipient using the user identification, wherein the push notification permits the user to retrieve the message body and the message identifier; and
permitting the user to verify, based on a comparison of the message identifier and using the decentralized bot, that the message was sent by the smart contract.
