How Blockchain Technology Works (Explained Simply)

Introduction:
Blockchain is the backbone of cryptocurrency, but many beginners find it confusing. In this article, we’ll explain blockchain in the simplest way possible, covering blocks, nodes, and mining.

🔹 What is Blockchain?

Blockchain is a digital ledger where data is stored in blocks. Each block is connected to the previous one, forming a chain.

🔹 Key Features of Blockchain

• Decentralized: No central authority controls it.
• Transparent: Anyone can verify transactions.
• Immutable: Once recorded, data cannot be changed.

🔹 How Does Blockchain Work?

1. A transaction is requested.
2. Nodes (computers) verify the transaction.
3. The transaction is added to a block.
4. The block is added to the chain permanently.

🔹 Why is Blockchain Secure?

Because thousands of computers verify every transaction, hacking a blockchain is nearly impossible.

Conclusion:
Blockchain is not just about cryptocurrency—it can be used in finance, healthcare, supply chain, and more. It’s one of the most important technologies of the 21st century.
