Cardano founder Charles Hoskinson has released a free book aimed at explaining zero-knowledge systems to a broader crypto audience, framing it as both an educational project and an on-ramp into Midnight, Cardano’s privacy-focused network. The linked GitHub repository shows the work is being published under a Creative Commons Attribution 4.0 license, while the latest public release is now titled Proving Nothing: A Layered Guide to Zero-Knowledge Proof Systems. Cardano Founder Drops Free 337-Page ZK Book In a March 27 livestream, Hoskinson said the project grew out of what he described as a “shockingly low level of understanding” around zero-knowledge proofs and ZK cryptography. “So I wrote a 337 page book over the last few months,” he said. He described it as a non-technical manual, though one that still contains a significant amount of technical material, built around a seven-layer framework for understanding how ZK systems are designed from setup and languages down to proof systems, cryptography, and the verification environment. I wrote a book https://t.co/FrzBeFEQbS — Charles Hoskinson (@IOHK_Charles) March 27, 2026 That structure is central to the pitch. The Cardano founder said the framework is meant to help readers “understand all ZK systems from that lens,” then move upward into adjacent privacy-enhancing technologies and, eventually, Midnight itself. The repository’s README makes the same case in more formal language, describing the book as a guide to “the entire zero-knowledge stack from the ground up” and arguing that ZK systems do not remove trust so much as decompose it into smaller, testable pieces. The Midnight angle is not incidental. Hoskinson explicitly presented the book as “a good way of introducing Midnight to people,” and said one chapter is dedicated to the network, even if the broader work is designed as a general introduction to zero-knowledge . He also said the book goes beyond the seven-layer model into private smart contracts, the Aleo-linked ZEXE model, Midnight’s Kachina system, zkVMs, STARK-to-SNARK pipelines, and the wider market landscape for privacy and proof systems. That scope has already expanded since the version Hoskinson described on video. The GitHub release notes for v1.10, published on March 30, show the book was renamed from The Seven-Layer Magic Trick to Proving Nothing, and now ships in both EPUB and PDF formats. The file inventory in that release lists a 357-page dark-mode PDF, while the chapter notes show edits and additions across 14 chapters, including sections on zkVMs , market structure, eIDAS 2.0, rollups, and a more detailed Midnight case study. new release for my book: Version 1.1 of Proving Nothing is out https://t.co/KAbk2jyHza — Charles Hoskinson (@IOHK_Charles) March 30, 2026 Hoskinson also made clear that this is not a static publication. “This is the first edition, version 1.01,” he said in the livestream. “I’ll keep adding and changing and work on it throughout the weekends as more things come up and as more stuff in Midnight gets launched, I’ll add to this.” That matters because the book appears designed less as a one-off manifesto than as a living educational document tied to Midnight’s rollout and the broader commercialization of privacy tech. At press time, Cardano traded at $0.2468.
