Before Trust Over IP Foundation, trust architects had a vision: a “trust layer” for the Internet could be achieved by following the same architecture as the Internet.
Each peer would be an instance of a standard “stack” of protocols, just as each device on the Internet runs an instance of the TCP/IP stack.
Today, that vision, with its combination of technology and governance, is seen in the two-sided, four-layer stack that we call the Trust Over IP Stack.
Note that the lower two levels focus on meeting the technical requirements of digital trust, while the top two layers focus on meeting the human requirements.
