Regardless of the specific application, the common theme of all blockchain technology is establishing trust across multiple independent parties. That is also the mission of digital identity technology, and over the past three years digital identity and blockchain technology have come together into a new decentralized identity model known as self-sovereign identity (SSI). As SSI has matured, it has spawned a four-layer interoperability stack very much like the TCP/IP stack that enabled that enabled the Internet. This talk will trace the origins of the Trust over IP (ToIP) stack, describe the purpose of all four layers (blockchain is only the first layer), explain why it is a “dual stack” of both technology and governance, and finally it will examine the business, legal, and social impacts of enabling a trust layer for the Internet.
