About BeABitcoiner
Free, open-source Bitcoin education — explained from first principles, not financial headlines.
Why This Exists
To make Bitcoin understandable for everyone. Not the price, not the hype — how it actually works under the hood. Every concept is broken down from its fundamental parts: cryptographic primitives, consensus rules, network gossip, and incentive design. No paywalls, no email required, no financial advice. Just knowledge.
Free & Open
All content is completely free. No subscriptions, no paywalls, no email required. Knowledge about Bitcoin should be as permissionless as Bitcoin itself.
First Principles
We never assume prior knowledge. Every concept is traced back to its foundations — from why hashing matters to why 21 million is the supply cap.
Practical & Clear
Theory meets practice. Every algorithm includes working code you can run yourself. Interactive tools like the block explorer and hash demo make concepts tangible.
Unbiased Education
We don't promote coins, push trading agendas, or give financial advice. BeABitcoiner covers Bitcoin protocol — the facts of how it works, nothing more.
Every topic is explained twice — once for the general reader using plain analogies, and once for the technical reader with precise detail. Pick your depth.
The SHA-256 hash demo, the live block explorer, and the Bitcoin parser exist because understanding by doing beats understanding by reading.
Satoshi's original paper is nine pages. The curriculum follows its logical arc — from the problem of trust to the solution of proof-of-work and beyond.
The Foundation section is for complete beginners. The Cryptography and Lightning Network sections go deep enough for developers building on Bitcoin.
