Bite #8: The Backbone of Bitcoin — Understanding Nodes

👋 Hello, Bitcoin Enthusiast!

Today’s topic is all about Nodes! Let’s break it down in simple terms so you can understand why they’re important and how they relate to Bitcoin.

🔍 What is a Node? 

In the world of Bitcoin, a node is a computer that participates in the Bitcoin network. Nodes communicate with each other to verify transactions, enforce the rules, and keep the entire system running smoothly. Think of it as a checkpoint in a big digital ledger that ensures everyone’s following the rules.

💡 Why does it matter? 

Nodes are crucial because they help maintain Bitcoin's decentralization. Without them, the network would rely on a few central entities, which could lead to censorship, fraud, or manipulation. Nodes keep Bitcoin honest and secure by ensuring that every transaction follows the same rules.

⚙️ How does it work? 

When you run a Bitcoin node, your computer downloads a full copy of the Bitcoin blockchain—this is like a giant history book of all Bitcoin transactions ever made. Your node then checks each new transaction against this book to make sure it’s valid. If everything checks out, your node shares this information with other nodes, helping to keep the entire network updated and accurate.
