Bitcoin is a decentralized digital currency introduced in 2009 by an anonymous entity known as Satoshi Nakamoto. Operating on a peer-to-peer network, Bitcoin eliminates the need for intermediaries like banks, relying instead on blockchain technology to secure transactions and maintain transparency.
Key Features of Bitcoin
- Decentralization: No central authority controls Bitcoin; transactions are validated by a distributed network of nodes.
- Limited Supply: Capped at 21 million coins, Bitcoin’s scarcity mimics precious metals like gold.
- Blockchain Technology: Transactions are recorded on an immutable public ledger, ensuring security and transparency.
- Pseudonymity: Users transact via cryptographic addresses, though complete anonymity isn’t guaranteed.
How Bitcoin Works
Mining and Supply
Bitcoin enters circulation through mining, where miners solve complex cryptographic puzzles to validate transactions and add blocks to the blockchain. Key aspects:
- Halving Events: Every ~4 years, block rewards halve to control inflation (3.125 BTC/reward as of 2024).
- Energy Use: Mining consumes significant electricity, driving innovation in renewable energy solutions.
- Final Bitcoin: The last coin will be mined around 2140, after which miners will rely solely on transaction fees.
Transactions
Bitcoin transactions involve:
- Sender initiates a transfer to a recipient’s wallet address.
- Network verifies the transaction via consensus.
- Blockchain records the transaction permanently after confirmation.
Layer-2 solutions like the Lightning Network enable faster, cheaper microtransactions.
