Abstract: The invention is a system and method for time and frequency-restricted cryptocurrency transactions that use blockchain-based systems, tokens, coins, and exchanges to reduce energy consumption and increase energy efficiency. The system imposes time and frequency-specific restrictions on transactions to reduce temperature yield and lower the carbon footprint, which contributes to climate change. Transactions within the designated “open or free trade” period may incur zero or reduced fees, and any transactions outside of the transactors' designated time or frequency limits may result in higher fees, which a portion results in carbon credit offsets. The invention also includes an “ejection button” that allows transactors to buy or sell outside of their designated time or frequency limits without higher fees, with a percentage of the proceeds resulting in carbon credit offsets. The invention provides a more energy-efficient and environmentally-friendly alternative to existing cryptocurrency systems.

Abstract: A three mirror-plane reflectoscope target acquisition accessory, with no moving parts, which mounts to the top, side or under any gun and many other apparatus to allow the user to: view, acquire and/or take action accurately from a cover and hidden position, around a corner, situating their person 90° to the side, above or below what is known as a typical firing position to the gun or host to which the tactical reflectoscope is affixed.
