🔗 Trust Chains
How linked, signed statements form an unbreakable chain
Build a Trust Chain — Step by Step
A Trust Chain is an ordered sequence of Entity Statements, starting with the subject's Entity Configuration and ending at a Trust Anchor's Entity Configuration.[1] Each intermediate link is a Subordinate Statement that cryptographically vouches for the entity below it.
Step 1 — Leaf Entity Configuration
How Verification Works
Verification proceeds top-down — start from the Trust Anchor whose key you already trust, and work your way down to the leaf.[2]
1. Start at Trust Anchor
Real-World Analogy
Imagine applying for a job abroad. Your resume (Entity Config) is backed by your professor's recommendation letter (Subordinate Statement), which is backed by the university president's confirmation (another Subordinate Statement), which terminates at the university's own identity document (TA Config). Each letter is signed by a different person, and the employer verifies them in order from the top.
