Bitcoin is a digital currency that was created in 2009 by Satoshi Nakamoto. It is decentralized, meaning that it does not have a central bank or government backing it. Instead, it is powered by a network of computers around the world that process transactions and verify each other’s work. Transactions are verified through a consensus system called “Proof-of-Work”, which requires miners to solve complex mathematical problems in order to add blocks to the blockchain. This process helps secure the network and prevents double spending of bitcoins.
