# bitcoin By [lukas](https://paragraph.com/@lukas-3) · 2024-02-17 --- Bitcoin is a digital currency that operates on a decentralized network known as blockchain technology. It was invented in 2008 by an anonymous person or group of people using the pseudonym Satoshi Nakamoto and released as open-source software in 2009. Bitcoin is often referred to as a cryptocurrency because it relies on cryptographic techniques to secure transactions and control the creation of new units. At its core, Bitcoin allows peer-to-peer transactions without the need for an intermediary like a bank or government. Instead, transactions are verified by network nodes through cryptography and recorded on a public ledger called the blockchain. This ledger is distributed across thousands of computers worldwide, making it highly resistant to censorship or manipulation. One of the key features of Bitcoin is its limited supply. Only 21 million bitcoins will ever be created, a rule hardcoded into its protocol. This scarcity is intended to mimic the properties of precious metals like gold and is often cited as a reason for Bitcoin's potential as a store of value. Bitcoin transactions are pseudo-anonymous, meaning that while the transaction history is publicly available on the blockchain, the identities of the parties involved are obscured by cryptographic addresses. However, it's important to note that these transactions can still be traced and analyzed to a certain extent. The price of Bitcoin has been subject to extreme volatility since its inception, experiencing dramatic fluctuations over short periods. Its value is influenced by various factors including market demand, investor sentiment, regulatory developments, and macroeconomic trends. Bitcoin's price reached an all-time high in late 2021, surpassing $60,000 per coin, before experiencing significant corrections. Despite its volatility, Bitcoin has garnered attention from both mainstream investors and institutions as a potential hedge against inflation and economic instability. Additionally, its underlying blockchain technology has inspired the development of numerous other cryptocurrencies and applications beyond currency, including decentralized finance (DeFi), non-fungible tokens (NFTs), and smart contracts. However, Bitcoin also faces challenges and criticisms. Its energy consumption, particularly through the process of mining – the computational process by which new bitcoins are created and transactions are verified – has drawn criticism for its environmental impact. Additionally, concerns about its scalability, regulatory uncertainty, and potential use in illegal activities have led to ongoing debates about its long-term viability and utility. Overall, Bitcoin represents a groundbreaking experiment in decentralized currency and has sparked a global conversation about the future of money, finance, and technology. Its journey continues to be closely watched by investors, regulators, technologists, and enthusiasts alike. --- *Originally published on [lukas](https://paragraph.com/@lukas-3/bitcoin)*
