The story of Bitcoin began in 2008, when a person or group of people under the pseudonym "Satoshi Nakamoto" published a white paper entitled "Bitcoin: A Peer-to-Peer Electronic Cash System". In this paper, the concept of a digital cash system based on blockchain technology was introduced to secure and verify transactions without the need for central intermediaries.
In 2009, the first Bitcoin program was launched, and the mining of the first block in the Bitcoin network, known as the "Genesis Block" or block number 0, began. The first miner was rewarded with 50 Bitcoins for mining this block.
After that, the Bitcoin network began to grow, as users began to exchange Bitcoins among themselves. In 2010, the first Bitcoin transaction was made, where two pizzas were purchased for 10,000 Bitcoin, which helped demonstrate the value of Bitcoin as a medium of exchange.
Since then, Bitcoin has seen tremendous growth in popularity, and many other digital currencies have emerged, but Bitcoin is still considered the first and most popular digital currency.
