Bitcoin employs peer-to-peer technology to operate without a central authority or banks; the network as a whole is responsible for handling transactions and issuing bitcoins. Since Bitcoin is an open-source project, anyone can participate, no one owns or controls it. Due to a number of its special characteristics, Bitcoin enables novel applications that were not possible with earlier payment systems.
High-performance computers are used for bitcoin mining to answer challenging computational arithmetic problems. These problems are so difficult to solve manually and are challenging enough to drain even the most powerful computers. The technique of producing new bitcoin by resolving a computer challenge is known as bitcoin mining. The transaction ledger that serves as the foundation for Bitcoin must be kept up to date through bitcoin mining. Over the past few years, miners have advanced significantly, using sophisticated technology to speed up mining operations.
