Instructor
Sora Han
Sora designs documentation drills for digital-asset operations teams. She previously led internal control writing for a Korea-based administrator and now focuses on teaching clear custody language at Logicdata Lab.
Module 5 forced me to delete three paragraphs of speculation from our incident template. The shorter note held up better in review.
Clear structure. I still wish the cold-storage module covered more vendor-specific quirks — the lab is honest that it teaches method, not every device menu.
FAQ
Do I need prior crypto trading experience?
No. You need familiarity with how your organization moves or stores digital assets, even at a basic level. Trading skill is not part of the rubric.
Will you review our live production ledgers?
Only redacted samples you choose to share. We do not accept seed phrases, private keys, or unrestricted system access.
What is a real limitation of this course?
We do not certify you as an auditor, lawyer, or licensed advisor. Completing the modules improves documentation habits; it does not replace regulated professional engagement in Korea or elsewhere.
