Think of it as a shared document where every participant has a copy, ensuring no single entity controls the data.

Key Components 🔗

  • Blocks: Data packets containing transaction records and timestamps
  • Chain: Linked list structure connecting blocks sequentially
  • Consensus: Mechanisms (PoW, PoS) to validate and add new blocks
  • Decentralization: Distributed network eliminates central authority

Each block is encrypted and tied to the previous one, creating an unbreakable chain.

Real-World Applications 🌐

  1. Cryptocurrencies (e.g., Bitcoin, Ethereum)
  2. Supply Chain Management
  3. Smart Contracts
  4. Decentralized Identity Systems
