What is bitcoin?


Bitcoin is a decentralized digital currency that operates without the intervention of a government or central bank. Unlike traditional fiat currencies, such as the dollar or euro, it does not have a physical form and exists only in the digital world. One of the most surprising features of Bitcoin is its divisibility: it can be divided into smaller units called satoshis, which represent one ten-thousandth of a Bitcoin.


How does the Bitcoin network work?


Bitcoin works thanks to thousands of computers distributed around the world, known as “nodes”. This decentralization ensures that there is no central entity controlling or supervising the system. Improvements to the Bitcoin protocol are carried out through formal proposals called Bitcoin Improvement Proposals (BIPs). Anyone can submit a BIP, and the community collectively approves or rejects proposals that modify Bitcoin's consensus rules, sometimes leading to forks.
