Understanding Blockchain and Cryptocurrency

Blockchain Fundamentals

Blockchain technology represents a paradigm shift in how we think about trust and verification in digital systems.

How It Works

At its core, a blockchain is a distributed ledger—a database that's replicated across many computers. Each block contains transaction data and is cryptographically linked to the previous block.

This creates an immutable record that's nearly impossible to tamper with.

Beyond Currency

While cryptocurrency is the most famous use case, blockchain has applications in supply chain, healthcare, voting systems, and more.
