The Blocksize War is Jonathan Bier’s 2021 history of Bitcoin’s 2015–2017 scaling conflict. Bier writes largely from the small-block perspective; motives and causality remain disputed and should be checked against primary archives and alternative histories.
Written by Jonathan Bier and first published in 2021 by BitMEX Research.
Use this book as a route into the people, conflicts and primary records that shaped Bitcoin’s history. Its Atlas links connect the reading to the people, mechanisms and events it discusses.
Primary or authoritative records make these details checkable: Jonathan Bier reconstructs Bitcoin's 2015–2017 block-size conflict from nodes, miners, companies, mailing lists, software releases and contemporaneous statements, with a chronology readers can compare to primary records. They should be verified before using the coordinate in analysis.
The practical limit is: the narrative reflects one research selection and terminology, not a court judgment or complete account of every participant; disputed motives and causality should be checked against archived code, messages and alternative histories. A definition, office, chart pattern or published claim is not by itself a prediction or Bitcoin consensus rule.
