How does Bitcoin work? Think of it as a shared notebook that everyone can see, but nobody can erase.
When you send Bitcoin to someone, you’re basically announcing to the network: “I’m sending 1 Bitcoin from my address to Bob’s address.” Thousands of computers hear this announcement and check if it’s valid. Do you actually have 1 Bitcoin? Is your signature real? If yes, they approve it.
Once approved, the transaction gets written into the shared notebook—permanently. Everyone’s copy updates at the same time. Now the whole network knows Bob has that Bitcoin, and you don’t anymore.
Here’s why this works: everyone has the same notebook. If someone tries to cheat—like spending the same Bitcoin twice—the other computers catch it immediately. Their notebooks don’t match. The fake transaction gets rejected.
No bank needed because the network itself does the bank’s job. Thousands of computers verify transactions, keep records, and prevent cheating. All through math, not trust.
So how does Bitcoin work? You announce a transaction. The network verifies it. Everyone records it. Done. It’s like email for money—direct, no middleman, and the network keeps everyone honest.
