Welcome to the world of Blockchain! This guide will walk you through the basics of blockchain technology, its key features, and real-world applications.

🔗 What is Blockchain?

Blockchain is a decentralized digital ledger that records transactions across many computers. It ensures security, transparency, and immutability through cryptographic techniques.

📝 Key Characteristics

  • Decentralization ⚙️
    No single entity controls the network.

    Decentralization

  • Immutability 🛡️
    Once data is added, it cannot be altered.

    Immutability

  • Transparency 🔍
    All participants can view the ledger.

    Transparency

🧠 How Blockchain Works

  1. Blocks are created with transaction data.
  2. Blocks are linked via cryptographic hashes.
  3. Consensus mechanisms (e.g., Proof of Work, Proof of Stake) validate new blocks.
