Abstract: Efficiency of a mining rig is improved by altering clock speed of an ASIC. Cock speed can be modified as a function of values for (B) a block reward for mining the cryptocurrency, (R) exchange ratio of a price of a cryptocurrency reward to a currency of a country, (D) difficulty or network hashrate, and (P) unit cost of electricity used to operate the ASIC, according to the function, B×R/D?P×?E/?i+?G/?i, where for overclocking by i percentage, an effective hashrate is 1+i, Ei is a change in an amount of electricity consumed, and Gi is a degradation or economic loss of the processor. ?E/?I can be inferred from temperature measurements and historical or calculated data. A mining rig can communicate with a blockchain network via a mining pool, with information from an oracle or a centralized crypto exchange.

Abstract: A method for execution by a marketplace server begins by receiving an indication of an intention to utilize an exchange item to support a purchase transaction associated with a computing device, where the exchange item is associated with an exchange item rule set. The method continues by determining one or more exchange items associated with the computing device and determining purchase requirements of the purchase transaction. The method continues by identifying alternative exchange items to potentially support the purchase transaction based on the purchase requirements, the one or more exchange items, and the exchange item rule set. The method continues generating a list of exchange item utilization solutions to support the purchase transaction. The method continues by the marketplace server sending the list of exchange item utilization solutions to the computing device.

Abstract: A method includes receiving exchange item information regarding an exchange item from a computing device of an exchange item marketplace network. The method further includes obtaining second exchange item information regarding a plurality of exchange items associated with the exchange item marketplace network based on the exchange item information. The method further includes determining an acquisition approach from a plurality of acquisition approaches for the exchange item and determining, based on the acquisition approach, an acquisition threshold for the exchange item based on the exchange item information, the second exchange item information, and acquisition rules associated with the exchange item.

Abstract: A method includes receiving, by a warehouse server, flash sale data file from a retail-type server. The method further includes storing, by the warehouse server, the flash sale data file in a database that functions as a virtual warehouse of flash sales. The method further includes interpreting, by the warehouse server, the information of the flash sale data file to determine flash sale parameters. The method further includes determining, by the warehouse server, whether a computing device has customer-device data that corresponds to the flash sale parameters. The method further includes, when the computing device has the customer-device data that corresponds to the flash sale parameters, generating, by the warehouse server, a customer specific coupon regarding the flash sale. The method further includes transmitting, by the warehouse server, the customer specific coupon to the computing device.
