Bitcoin was born in 2008 when a person or group under the pseudonym **Satoshi Nakamoto** published a technical document proposing a decentralized digital money system. In January 2009, the Bitcoin network was launched, with Nakamoto mining the first block, known as the **genesis block**

Bitcoin is based on **blockchain** technology, a chain of blocks that securely and transparently records all transactions. It operates without intermediaries like banks, allowing users to send and receive money directly. Its security system is based on cryptography and a mechanism called **proof of work**, which requires miners to solve mathematical problems to validate transactions

Since its creation, Bitcoin has evolved from being a revolutionary idea to becoming a speculative asset with a significant impact on the financial world
