Blockchain technology has been a game-changer in the digital world. It's a decentralized, secure, and transparent way to record transactions. Let's dive into the basics and explore how it works.

What is Blockchain?

A blockchain is a chain of blocks. Each block contains a list of transactions. Once a block is filled with transactions, it is added to the chain. The process is secure because each block contains a unique code that links it to the previous block, creating an immutable record of transactions.

How Does Blockchain Work?

  • Decentralization: Unlike traditional banking systems, blockchain operates on a decentralized network. This means that no single entity has control over the entire system.
  • Security: Transactions are secure due to advanced cryptography. Each transaction is encrypted, and the encryption keys are distributed across the network.
  • Transparency: All transactions are recorded on the blockchain, making it easy to verify and audit.

Use Cases of Blockchain

  • Cryptocurrency: The most famous use case of blockchain is cryptocurrencies like Bitcoin.
  • Smart Contracts: These are self-executing contracts with the terms of the agreement directly written into lines of code.
  • Supply Chain Management: Blockchain can help track and verify the origin of goods and products.
