⚙️ How Bitcoin Works (classic)

The original under-the-hood track

The original Pillar 4, kept as an elective: the shared ledger, mining and block rewards, the 21-million cap and halving, and the self-adjusting difficulty clock — no code or math.

The Shared Ledger

Before miners or math, Bitcoin is really just a very clever notebook.

  1. 📒 The Shared Notebook
    What "the blockchain" actually is — minus the jargon.
  2. 👀 Why No One Can Cheat
    No bank, no referee — so who enforces the rules?

Mining

How new pages get added — and why anyone bothers.

  1. ⛏️ What Miners Actually Do
    Hint: they’re not digging, and it’s basically a raffle.
  2. 🎁 Getting Paid to Keep the Books
    Where new bitcoin comes from, and who mints it.

The Rules That Never Bend

The two rules that make Bitcoin’s money supply predictable forever.

  1. ✂️ The Halving & 21 Million
    Why the supply is capped — and knowable decades ahead.
  2. 🌡️ The Self-Adjusting Clock
    The quiet mechanism that keeps everything on schedule.
