Messaging protocol to faciliate demand-based messaging

A system comprising:

• a receiver device to receive information defining each of a set of message types, wherein each of the set of message type templates comprises a cost transaction and message criteria for executing the cost transaction;
• a sender device to:
• receive, via a user interface (UI) for selecting among the set of messages types, a selection of a message type from the set of messages types and message content;
• and
• transmit a user message having the selected message type and the message content to the receiver device;
• and
• a central messaging server to:
• create a message transaction to monitor one or more actions taken by the receiver device with respect to the user message to determine whether message criteria associated with the selected message type has been satisfied;
• and
• in response to determining that the message criteria associated with the selected message type has been satisfied, process a cost transaction associated with the selected message type between the sender device and the receiver device.

A non-transitory computer-readable medium having instructions stored thereon which, when executed by a processing device, cause the processing device to:

• receive from a sender device, a user message, wherein the user message comprises a message of a selected type among a set of message types, wherein each of the set of message types comprises a cost transaction and message criteria for executing the cost transaction;
• transmit the user message to a receiver device;
• create, by the processing device, a message transaction to monitor one or more actions taken by the receiver device with respect to the user message to determine whether message criteria associated with the selected message type has been satisfied;
• and
• in response to determining that the message criteria associated with the selected message type has been satisfied, processing a cost transaction associated with the selected message type between the sender device and the receiver device.
