The Bitcoin Blockchain Explained

How does the blockchain actually work?

In this video, I break down the entire process step-by-step in the simplest possible way - what Bitcoin is, how blocks are created, how miners solve cryptographic puzzles, how nodes verify transactions, and why the blockchain is considered the most secure financial network in the world.

Whether you're brand new or already deep into crypto, this is the clearest explanation of how blockchain technology works - without hype, without jargon, and without confusing technical nonsense.

The blockchain is the foundation of Bitcoin - a global network where thousands of computers agree on the same truth without trusting each other. This video explains how blocks link together, how proof-of-work functions, and why Bitcoin’s decentralized design makes it almost impossible to alter or fake transaction history.

If you've ever wondered:
“How does the blockchain work?”
“How does Bitcoin actually work?”
“What is a block? What is a node? What is mining?”
“Why is the blockchain secure?”

this video answers all of that clearly and visually.

Understanding how the blockchain works is the first step to understanding Bitcoin, crypto, and the future of decentralized technology. This is the exact explanation I wish I had when I first discovered Bitcoin.
