Beta completeApplications closed
The invite-only Beta review is complete.
A small qualified cohort reviewed focused paths through the book. One participant supplied substantive technical feedback; every received finding was adjudicated without calling the process peer review or an audit.
The cohort opened August 3 and closed August 21, 2026. The resulting RC4 candidate is now available through Paid Early Access.
Review design
Specific readers. Specific failure reports.
The completed small qualified cohort covered focused technical reading and format feedback. It was not a broad sample and does not support claims of peer review, audit, or market validation.
CRYPTO / ZK

Self-study and device testers
Find unclear prerequisites, broken learning flow, EPUB/PDF defects, and zh-TW localization problems.
What invited readers received
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 the review requested
Evidence, not endorsement.
- Review a bounded path rather than promise a whole-book read
- 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
- Report concrete failures without requiring a positive recommendation
Reader tracks
Go deep where you can be specific.
Readers could choose more than one area; invited participants received a bounded assignment rather than a 300+ page obligation.

Privacy and confidentiality
Only the information needed to select a useful cohort.

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.
