Bitcoin is a digital currency, sometimes referred to as an encrypted currency, known as the first truly decentralized digital currency in the world. Trading is done on a peer-to-peer basis with a distributed ledger, Blockchain, and the exchange rate is determined to the US Dollar and other major currencies in terms of supply and demand as is the case with other global exchange rates. Pitcone's value has proved to be volatile through many boom and bust demand. But in the end, many see it as a store of value against government-backed banknotes.
Existing communications and computer architecture are increasingly being limited by the pedestrian speed of electrons moving through wires, and the future of high-speed communication and computing is in optics, experts say. The Holy Grail of results would be "wireless interconnecting," which operates at speeds 100 to 1,000 times faster than current technology. The new discovery, made by researchers at Oregon State University, the University of Iowa and Philipps University in Germany, has identified a way in which nanoscale devices based on gallium arsenide can respond to strong terahertz pulses for an extremely short period, controlling the electrical signal in a semiconductor. The research builds on previous findings for which OSU holds an issued patent.
