Bitcoin is a decentralized digital currency, often referred to as a cryptocurrency. It was created in 2009 by an unknown person or group of people using the pseudonym Satoshi Nakamoto. Bitcoin operates on a peer-to-peer network, meaning transactions occur directly between users without the need for an intermediary like a bank.
Key Features of Bitcoin:
1. Decentralization: Unlike traditional currencies, Bitcoin is not controlled by any central authority. Instead, it relies on a distributed ledger technology called blockchain, which records all transactions across a network of computers.
2. Limited Supply: There will only ever be 21 million bitcoins in existence. This scarcity is built into the system to mimic the finite supply of precious metals like gold.
3. Transparency and Security: All Bitcoin transactions are recorded on the blockchain, which is publicly accessible and immutable. This ensures transparency and security, as each transaction is verified by network nodes through cryptography.
4. Anonymity: While transactions are transparent, the identities of the users involved are pseudonymous. Users are identified by their wallet addresses rather than personal information.
5. Low Transaction Fees: Bitcoin transactions typically have lower fees compared to traditional banking systems, especially for international transfers.
How Bitcoin Works:
- Mining: New bitcoins are created through a process called mining, where powerful computers solve complex mathematical problems. Miners are rewarded with bitcoins for their efforts, which also helps to secure the network.
- Transactions: Users can send and receive bitcoins using wallet software on a computer or mobile device. Each transaction is broadcast to the network and included in the blockchain after being verified by miners.
Uses of Bitcoin:
- Many people buy and hold bitcoins as an investment, hoping that its value will increase over time.
- BTC can be used to purchase goods and services from merchants who accept it as a form of payment.
