This ToIP wiki page is a starting point for anyone new to the concept of Trust over IP who wants to start with a high-level picture of introduction to the ToIP stack and the ToIP Foundation.

At the very core of ToIP is the ToIP stack—a the ToIP stack—a four-layer model for interoperable decentralized digital trust infrastructure. Below is a static picture of this stack, but the best way to learn about the this stack is using via this interactive model on the ToIP website.
Evolution of the ToIP Stack
As work on the ToIP stack progressed, in November 2022 the Foundation published a new document called Evolution of the ToIP Stack to provide an overview of the four stages that development is progressing through. We highly recommend this document to put the work of the ToIP Foundation into context.
Design Principles for the ToIP Stack
If you are intrigued by what you have read above, another resource that can help you understand ToIP at a deeper level is the Design Principles for the ToIP Stack. Produced through by 22 ToIP Foundation members via a series of community writing workshops held over four months in the fall of 2021, this 58-page document explains the 17 design principles guiding the development of the ToIP stack across all ToIP Foundation working groups and task forces.

The concept of the ToIP stack originated with ToIP Foundation Executive Director John Jordan and a group of Internet architects who were deeply involved with decentralized digital identity, sometimes called self-sovereign identity or SSI. These architects were convinced that the core concepts of decentralized digital wallets and credentials could and credentials—and the combination of cryptography and governance that made them work—could be the basis for finally establishing an interoperable trust layer for the Internet that could address longstanding issues in cybersecurity, privacy, data protection, and digital trust. After developing a core design for the ToIP stack, they published an article called The Trust Over IP Stack in the December 2019 special issue of IEEE Communications Standards Magazine called The Dawn of the Internet Identity Layer and the Role of Decentralized Identity.
