⚙️ How Bitcoin Actually Works

Okay, but how does it work?

Under the hood, in plain language. What actually proves you own bitcoin, what happens between hitting send and being confirmed, why mining secures anything at all, how blocks chain together, and who checks that everyone is playing by the rules.

Ownership & Payment

The secret that proves it's yours — and what happens when you spend it.

  1. 🔑 Keys & Wallets: Your Digital Vault
    You don't store bitcoin. You store the secret that proves it's yours.
  2. 📡 Sending a Transaction
    What actually happens between "send" and "confirmed."

The Machinery

Mining, the chain, and the computers that keep everyone honest.

  1. ⛏️ Mining & Proof of Work, Simply
    Nobody's digging anything up. It's a race — and the race is the security.
  2. ⛓️ The Blockchain: A Ledger Everyone Can Check
    Rip out one page and every page after it looks wrong.
  3. 🖥️ Nodes: Verify, Don't Just Trust
    Miners build the blocks. Nodes decide whether to accept them.
