What Is Bitcoin?
Bitcoin is a cryptocurrency designed by Satoshi Nakamoto, a pseudonym used by its creator (or creators)—its true identity remains unknown. Launched in 2009, Bitcoin exists solely online, independent of banking systems or national sovereignty, unlike traditional currencies like the US Dollar or Brazilian Real. Its operational code is BTC.
All Bitcoin transactions are recorded on the blockchain, a decentralized ledger created by Nakamoto. The blockchain consists of encrypted blocks of data (block) linked in a chain (chain), ensuring secure and transparent validation of cryptocurrency transactions.
While Bitcoin isn’t the only cryptocurrency, it’s often used synonymously with "crypto." Many people say they’ve "bought Bitcoin" when they’ve actually purchased other cryptocurrencies.
What Is a Cryptocurrency?
A cryptocurrency is virtual money not issued by any government.
Think of it like digital cash—instead of paper bills, Bitcoin is a virtual currency built on cryptographic principles. This encryption prevents fraud, ensures security, and enhances the efficiency of digital payments.
Key advantages of Bitcoin payments:
- No intermediaries: Faster, cheaper transactions.
- Global accessibility: Send/receive funds worldwide without limits.
- Enhanced security: Reduced risk of fraud.
What Is Bitcoin Used For?
Bitcoin serves three primary functions:
- Facilitating commercial transactions.
- Acting as a store of value (like gold).
- Functioning as a unit of account (pricing goods/services against other currencies).
How Does Bitcoin Work?
Bitcoin operates on a peer-to-peer (P2P) network, eliminating the need for central servers or banks. Benefits include:
- Lower fees: No transfer or maintenance costs.
- Instant transactions: No delays between institutions.
Bitcoin Mining Explained
Mining validates transactions and adds them to the blockchain, generating new Bitcoins as rewards. Here’s how it works:
- High-performance computers solve complex calculations (Proof of Work).
- Each solved block earns miners Bitcoin rewards.
- Every 4 years, rewards halve (an event called halving). In 2024, miners earn 3.125 BTC per block, down from 6.25 BTC in 2020.
⚠️ Note: Mining consumes significant energy, raising environmental concerns.
