What is Bitcoin (BTC)?

Bitcoin is the first and most widely recognized cryptocurrency. It enables peer-to-peer exchange of value in the digital realm through the use of a decentralized protocol, cryptography, and a mechanism to achieve global consensus on the state of a periodically updated public transaction ledger called a ‘blockchain’.

Bitcoin’s Origin, Purpose, and Technology

Bitcoin was created by an anonymous entity under the pseudonym “Satoshi Nakamoto” who published the Bitcoin whitepaper in 2008 and released it as open-source software in 2009. The stated purpose was to create “A purely peer-to-peer version of electronic cash that would allow online payments to be sent directly from one party to another without going through a financial institution.”

Some of the key technical innovations of Bitcoin include:

• The blockchain – a public and immutable ledger
• Proof-of-work consensus mechanism for validating transactions
• Limited supply of 21 million coins
• Halving events approximately every four years
• Decentralized governance structure

Bitcoin’s Market Position

Bitcoin maintains its position as the largest cryptocurrency by market capitalization and is often referred to as “digital gold” due to its store of value properties. It has inspired thousands of other cryptocurrencies and blockchain projects, which are collectively referred to as altcoins.
