A prepaid computer service operating on a personal computer and a networked computer is activated at a point of sale. The secondary display presents a count of messages that are waiting to be accessed by the mobile device user. In both upsteam and downstream modes of operation, the transmission is bypassed to increase flywheel energy storage and use, as well as expanding the functionality of the flywheel. In another embodiment, the auction operator computes the auction results and publishes proofs of the results’ correctness. A search result is then received from the database and provided to the user.
