Bitcoin is a decentralized digital currency that was created in 2009 by an anonymous individual or group known as Satoshi Nakamoto. It allows for secure and seamless peer-to-peer transactions on the internet without the need for traditional intermediaries like banks. Bitcoin transactions are verified through a shared public ledger called the blockchain, which is copied across every computer connected to the bitcoin network. The verification process involves a consensus system called proof of work, which requires significant computing power to secure the network and prevent fraudulent transactions. Bitcoin can be bought, sold, and exchanged through various platforms and wallets, and its value is determined by market demand and supply.
