THE SITUATION ROOM · PROTOCOL SCHOOL
The Cipher School
How Bitcoin actually works, from first principles — a school that exists because randomness failures keep costing people their coins.
Eight modules take you from the idea of a ledger nobody can rewrite to the practice of holding your own coins for decades. Along the way the curriculum keeps returning to one uncomfortable truth: your security reduces to the quality of a random number, and randomness must be verified, not trusted. Every module carries an interactive demo you can break with your own hands, a reading ladder, and a field test. Work through them in order and a hardware wallet stops being a magic box.
The curriculum
8 MODULES
First Principles
4 MODULES
The ideas the machine is built from. A shared ledger nobody can rewrite, keys that prove ownership without revealing themselves, the randomness those keys stand on, and the twelve words that encode it all.
The Machine
3 MODULES
How the system actually runs. Coins as unspent outputs, the mining lottery that orders history, and the full nodes that hold every miner to the rules.
Field Craft
1 MODULE
The practice of holding your own. Threat models, single signatures versus multisig, and the discipline that keeps a stack safe for decades.
