Bitcoin only.
No altcoins. No tokens. No "crypto." Other coins have other sites. We have one.
The Bitcoin School
For people who want to understand Bitcoin. Not flip it.
Plain language. Sourced chapters. Live on-chain data from a real node. Huge glossary, Rabbit Holes, and one opinionated Journey from "what is money?" to running a full node. No altcoins, no affiliate links, no newsletter pitch.
No bullshit.
No price predictions. No affiliate-bait. No fear marketing. Every chapter cites its sources, and the live on-chain numbers come straight from a full Bitcoin node.
Have fun.
Interactive, opinionated, well-crafted. Rabbit-hole vibes. Built by Bitcoiners for people who want to actually understand.
Down the rabbit hole.

The 2013 Chain Fork
On 11 March 2013 a software upgrade split Bitcoin into two chains. Developers, pool operators and exchanges argued it out in a public chat room and put it back together in under eight hours. This is the log, with the timestamps.
