How does Bitcoin work in simple terms?
Posted to: Bitcoin
Can someone explain how Bitcoin works in the simplest way possible? I’ve heard about it being a digital currency and something to do with blockchain technology, but I’m still not quite sure how it all fits together. How do transactions get verified without a bank or middleman? And what’s this process of mining I keep hearing about? I’d love an easy-to-understand explanation that breaks it down step by step.

Bitcoin is a type of digital money, but unlike the dollars in your bank account, it’s completely decentralized. That means no banks, no governments, and no single company controls it. Instead, it’s run by a network of computers all over the world. These computers work together to maintain a digital ledger called the blockchain. You can think of the blockchain as a giant public spreadsheet that records every Bitcoin transaction ever made. Everyone can see it, and because it’s stored across so many computers, it’s almost impossible to tamper with.
Here’s how it works: when you send Bitcoin to someone, your transaction is broadcast to this network. The computers, called nodes, check to make sure the transaction is valid—like, did you actually have enough Bitcoin to send? Once it’s verified, your transaction gets bundled with others into a "block." But before that block can be added to the blockchain, it has to be confirmed by a process called mining.
Mining is kind of like a lottery. Miners, who are people or groups with super-powerful computers, compete to solve a really tough math problem. The first miner to solve it gets to add the block of transactions to the blockchain and earns a reward in Bitcoin. This mining process does two things: it secures the network from fraud and ensures that new Bitcoin is slowly released into circulation.
The beauty of Bitcoin is that it’s decentralized, so no single person or entity can mess with it. It’s also completely transparent because anyone can view the blockchain to see what’s happening. And since it’s digital, you can send Bitcoin to anyone, anywhere in the world, anytime, without needing a bank or paying crazy fees. It’s like having a global currency that’s not tied to any government—it’s really a fascinating system once you dig into it.
