Bitcoin is a digital currency 🪙 that was born in 2009 with a clear mission: to enable financial transactions without the need for banks or intermediaries. Unlike traditional money, it does not exist in physical form and is based on a decentralized network of computers known as blockchain.
🧠 Origin: An alternative financial system
Bitcoin was created by a person (or group) under the pseudonym Satoshi Nakamoto, who published a technical document (white paper) in 2008 titled "Bitcoin: A Peer-to-Peer Electronic Cash System." In January 2009, the genesis block was mined, officially starting the Bitcoin network.
Its emergence occurred shortly after the financial crisis of 2008, as a response to the loss of confidence in the traditional banking system.
🔧 Technological foundation: the blockchain
Bitcoin is based on a technology called blockchain, which is a public and transparent ledger where all transactions are recorded.
Each transaction is verified by users of the network called miners, who, by solving complex mathematical problems, ensure the validity of the system. As a reward for their work, they receive new bitcoins.
Bitcoin has a limited supply: only 21 million coins will ever exist, which reinforces its value as a scarce asset.
