Black Belt Legacy

Black Belt Legacy is a public record of who promoted whom in the Machado / Bob Bass Brazilian Jiu-Jitsu lineage: a lineage tree where every rank names the teacher who awarded it and every claim is reviewed by a steward before it is marked verified.

It is for practitioners training in the Machado / Bob Bass BJJ line who want their rank and teacher on the public record, instructors whose students are part of that lineage, and visitors researching a person, school, or branch of the tree.

If you already appear on the tree as an unclaimed entry, you register for free, confirm your rank and the teacher who promoted you, and submit any supporting evidence; a steward reviews it before your account attaches to that record. If you are not on the tree yet, you can register and name your instructor even if that instructor has not joined, and you will be placed as a new entry under them.

Verified means a steward, a person with review permission, checked the record and marked it verified. It is never set automatically, and it applies whether the record was originally imported or submitted through a claim; a record that has not been reviewed shows as unverified or imported instead.

Claiming your profile and having your rank verified is free; there is no charge to be reviewed. Paid membership tiers add features to the profile itself, such as a fuller profile, video, and certificate, never the verification itself, and the verified badge is never for sale.

Submit a data request through the site's privacy request form (you must be signed in) and choose 'Correct or update my data'; a person handles it. Black Belt Legacy's stated policy is to keep disputed or historical information visible rather than deleting or silently rewriting it.

Black Belt Legacy is a first-party project of Ronin Dojo Design. Instructors and lineage figures named on the tree, including Rigan Machado and Bob Bass, appear as lineage facts the record keeps; their presence is not an endorsement, partnership, or approval of the platform.
