Introduction to Blockchain Technology
Blockchain serves as the foundation for Bitcoin and other cryptocurrencies. This decentralized technology offers transparency, security, and immutability through its distributed ledger system.
Key Components of Blockchain
- Digital Signatures: Ensure authentication and non-repudiation
- Immutable Records: Once added, data cannot be altered
- Consensus Mechanisms: Validate transactions without central authority
