Black Belt Legacy
Preserve, verify, explore, and share your martial arts legacy — through profiles, lineage trees, rank history, curriculum, certifications, and community knowledge.
Launched June 19, 2026.
What is Black Belt Legacy?
Black Belt Legacy is the heritage-and-community home for martial artists — the place where identity, lineage, rank history, instructors, schools, stories, and trust signals come together.
Martial arts history is scattered across personal sites, gym pages, social posts, old photos, and fading memories. A practitioner can be real, influential, and historically important — and still be impossible to verify online. Black Belt Legacy fixes that: a verifiable profile, a provable promotion timeline, and a living lineage network, built to be worthy of the arts it records.
