Bitcoin Guides

Explainers for readers who want to understand Bitcoin properly rather than merely follow its price. Each guide starts from first principles and assumes no prior knowledge.

Start here

• What a bitcoin actually is, and what it means to own one.
• How a transaction travels from a wallet to a confirmed block.
• Why the 21 million limit is credible, and what enforces it.
• Fees, mempools and why a transaction can sit unconfirmed.
• Lightning: what it solves, and what it costs you in convenience.

Then go deeper

Once the basics are clear, the Analysis section carries longer pieces on market structure, mining economics and protocol development.
