Why this exists
This book began as a question I could not answer to my own satisfaction: if privacy is a property of money rather than a feature bolted onto it, which money actually has it — and how would you check?
I hold EPIC, and I have for years. Assume that colours everything here, then check the work anyway. Every number in this book is either arithmetic, visible on a public chain, or attributed to a named source with a date.
I have also been wrong about timing, repeatedly. The argument is meant to stand without me: a test sharp enough to settle the question without the author in the room.
This site is free. There is nothing to buy, no email to give, no account to create. Read a chapter, or let it be read to you.
The whole book as a PDF — 135 pages, the same text you have been reading, and the same version.
This is a living document. It is revised as new research arrives and as readers send corrections, which is why the version and date above are printed on it. What you download here is always the current edition — not a snapshot from whenever this page was built.
