FAQ
Questions about how NodeScholar itself works — whether you need an account, how progress is saved, and what the labs are. For crypto-concept questions, see the modules and the glossary; for common myths and misconceptions, see Misinformation & Misnomers.
No. There are no accounts, no login, and no server. All of your progress is stored locally in your browser (in localStorage) and is never sent anywhere or shared with anyone.
No. NodeScholar is educational content only. Nothing here is a recommendation to buy, sell, or hold any asset, or to take any legal position. See the disclaimer in the footer of every page.
Yes. The site is 100% client-side; once a page is loaded it runs in your browser with no external API calls. Sources are cited with URLs for you to look up later — they are never fetched automatically.
Yes. The Reset button in the header clears all module, lab, learning-path, flashcard, and final-exam progress stored in your browser. It cannot be undone.
19 modules, 10 interactive labs, and a final exam. Each module shows an estimated time (roughly 8–20 minutes). You can take it in any order and at any pace; the Learning Paths suggest sensible orders for different goals.
A sandbox is a safe, simulated environment where you can experiment with no risk to real money, real keys, or real transactions. Everything in a NodeScholar sandbox stays in your browser. The labs are all sandboxes.
Progress lives only in your current browser's localStorage. Clearing browser data, using private/incognito mode, or switching to a different browser or device starts you fresh. There is no server-side copy to restore from.
Because handling real funds in a teaching tool would be unsafe. All lab coins (NSC and others) are simulated and hold no monetary value — they exist only so you can learn how sends, fees, confirmations, and tracing work without risk.
No. The labs are simulations only; there is no way to transact, hold, or move real funds from this site. NodeScholar teaches the concepts — it is not a wallet, an exchange, or a payment app.
