## Mission & Principles

Block Clarity Hub is a purely educational, non-commercial cryptocurrency resource designed to help people understand blockchain technology, cryptocurrencies, and the broader digital asset ecosystem. The site contains no affiliate links, no sponsored content, and no financial advice. All content is written for progressive difficulty levels (Beginner, Intermediate, Advanced) so that both newcomers and experienced users can learn at their own pace.

All statistics are sourced from reputable organizations including FBI IC3 (Internet Crime Complaint Center), Chainalysis annual reports, and CertiK security research. Market data is provided by the CoinGecko API and refreshes every 15 minutes on applicable pages.

## Self-paced Courses

The site hosts structured, multi-lesson courses at `/courses`. Each course
is purely educational, uses static content + localStorage progress tracking,
and contains a final quiz that marks the course complete on pass. No
financial advice, no affiliate links, no paid placements.

  lessons (~20 min each) plus a 10-question final quiz. Covers the
