What Is Cryptocurrency & Blockchain?

Cryptocurrency and blockchain are two of the most transformative technologies of the 21st century. While cryptocurrency is a digital currency designed for secure online transactions, blockchain is the underlying decentralized ledger technology that powers it.

The combination of these innovations has sparked a financial revolution — offering decentralized, secure, and transparent transactions without the need for traditional banking systems.

How Blockchain Technology Works

At its core, blockchain is a distributed digital ledger that records transactions across multiple computers. This ensures that records are secure, tamper-proof, and transparent.

🔐 Key Features of Blockchain:

• Decentralization: No central authority controls the data

• Immutability: Once data is recorded, it cannot be altered

• Transparency: All participants have access to the ledger

• Security: Uses cryptographic algorithms to ensure trust

Each block in the blockchain contains:

• A batch of transactions

• A timestamp

• A reference (hash) to the previous block

This chain of blocks makes the system highly secure and verifiable.
