IOTA Hierarchies — Building Verifiable Authorization Structures

If Notarization is about how to record the "truth," then Hierarchies are about how to distribute "power." This is a crucial leap from "single-point trust" to "ecosystem trust." In this course, we will delve into the Hierarchies module of the IOTA Trust Framework, from the underlying Move model design to advanced SDK practice, and use real-world case studies such as ADAPT digital trade to demonstrate how to build a verifiable, programmable, and collaborative global authorization infrastructure across organizations.
