Bitcoin

Bitcoin is a decentralized digital currency that enables peer-to-peer transactions over the internet without the need for a central authority or intermediary, such as a bank or government. It was created in 2009 by an anonymous person or group of people using the pseudonym Satoshi Nakamoto. Bitcoin transactions are recorded on a public ledger called the blockchain, which ensures transparency and security.Bitcoin operates on a technology known as blockchain, which is a distributed ledger maintained by a network of computers (nodes) that participate in the Bitcoin network. Each transaction is grouped into blocks and once validated by the network, it is added to the blockchain, making it immutable and verifiable.Bitcoin is often referred to as a cryptocurrency because it uses cryptographic techniques to secure transactions and control the creation of new units. The total supply of Bitcoin is capped at 21 million coins, which contributes to its scarcity and value proposition.As the first cryptocurrency, Bitcoin has inspired the development of thousands of alternative cryptocurrencies, collectively known as altcoins. It is often used as a store of value or a medium of exchange, and has gained varying degrees of acceptance in retail and investment markets.
