Overview
Bitcoin and blockchain are often used interchangeably, but they are distinct concepts. Bitcoin is a cryptocurrency that utilizes blockchain technology, while blockchain is a decentralized, distributed ledger that enables secure and transparent transactions, as seen in the use of blockchain by companies like Microsoft and Google, and the implementation of blockchain-based systems by countries like Estonia, with the help of experts like Tim Berners-Lee and Vitalik Buterin, who have also worked on projects like Ethereum and the development of Web3.
