ENGINEERING
Security and software builders
Review assumptions, state, APIs, protocol integration, key lifecycle, and failure recovery.
Invite-only BetaNo purchase · no payment
Help stress-test a security-first guide to modern cryptography.
Read a focused path—not necessarily the whole book—and report where the definitions, proofs, examples, code, or formats fail you.
Target cohort opening: August 3, 2026. Release gates override dates. Applying does not guarantee selection.
Who this is for
Specific readers. Specific failure reports.
We are building a small 8–12 reader cohort across engineering, cryptography, zero knowledge, self-study clarity, localization, and real-device QA.
CRYPTO / ZK
Specialists and research learners
Attack definitions, reductions, encodings, constraints, public inputs, and verifier boundaries.
READING / FORMAT
Self-study and device testers
Find unclear prerequisites, broken learning flow, EPUB/PDF defects, and zh-TW localization problems.
What accepted readers receive
A focused review package.
- A named chapter track from the v1.0.0-rc.3 content-complete candidate
- English canonical edition; selected zh-TW companion review where relevant
- PDF, EPUB, Markdown, and educational code only as assigned
- A feedback guide, deadline, support route, and issue severity rubric
- Material corrections through the Beta window
What we ask
Evidence, not endorsement.
- Choose one path and commit the hours stated in your application
- Identify the exact chapter, section, version, device, or code example
- Describe observed versus expected behavior and reproduction steps
- Keep private review files and links confidential
- Submit focused feedback by the August 17 target when selected
Reader tracks
Go deep where you can be specific.
Applicants may choose more than one; accepted readers receive a bounded assignment rather than a 300+ page obligation.

Read the public English sample.
Choose PDF (177 KB), EPUB (125 KB), or Markdown (41 KB). The sample contains the front matter, Preface, study guide, Chapter 0, and Chapter 1 only; it does not expose paid chapters or companion code.
Privacy and confidentiality
Only the information needed to select a useful cohort.
The Zoho form asks for contact details, public technical context, track and device preferences, availability, and separate application/contact/optional quote choices. It does not request a phone number, home address, employer-confidential information, identity documents, financial information, or private keys.
Unaccepted applications are deleted or anonymized by November 15, 2026. Necessary accepted-reader contact and operating data may be kept through August 17, 2027, then deleted or anonymized. Anonymous aggregate statistics may remain without a fixed deletion date.
Application consent is not marketing consent. Read the privacy notice and contact [email protected] for access, correction, consent withdrawal, or deletion.
