How Does Bitcoin Work?
Bitcoin runs on a peer-to-peer network where users validate transactions through a process called mining. Miners use powerful computers to solve complex mathematical puzzles, and the first to solve it adds a new block to the blockchain and earns a reward in This process is known as proof of work.
Each transaction is secured using cryptographic keys and recorded on the blockchain, ensuring that no one can alter the transaction history. The system is designed to be secure, transparent, and resistant to fraud.
