Bitcoin is the pioneering digital asset that revolutionized finance by introducing cryptocurrencies to the world. From individual investors to institutional giants, Bitcoin has captured global attention as a decentralized alternative to traditional money.
Introduction: Core Principles of Bitcoin
Bitcoin is built on groundbreaking principles that challenge conventional financial systems:
- Decentralization: No central authority controls Bitcoin. Transactions are verified by a distributed network of nodes.
- Scarcity: Only 21 million BTC will ever exist, making it a deflationary asset.
- Pseudonymity: Transactions are public, but users aren’t required to reveal personal identities.
- Open-source: Bitcoin’s code is transparent and community-driven.
- Peer-to-peer (P2P): Users transact directly without intermediaries.
How Bitcoin Works: Blockchain, SHA-256, and Proof of Work
Bitcoin operates on a blockchain—a decentralized ledger that records transactions chronologically. Key components include:
Blockchain Basics
- Blocks contain transaction data, timestamps, and a cryptographic hash of the previous block.
- New blocks are added roughly every 10 minutes via mining.
SHA-256 Encryption
Bitcoin uses SHA-256, a secure hashing algorithm that converts data into a unique 256-bit hash. This one-way function ensures tamper-proof transactions.
Proof of Work (PoW)
Miners compete to solve complex mathematical puzzles to validate transactions. The first to succeed earns newly minted BTC and transaction fees.
