This project analyzed alternative ways to enable transparency for stakeholders in a trust service-based ecosystem, besides traditional third-party certification. One of the most popular trends in this area is Certificate Transparency (CT) initiated by Google. The underlying principles of CT or other transparency-related efforts (such as Revocation Transparency, Key Transparency, etc.) are not specific to a domain and can be used to add transparency in general to a trust model. This Transparency paradigm allows for a more decentralized way of generating trust. This project analyzed the data structures and their applications that would enable adding transparency to a trust model and investigated further trust ecosystems that this model can benefit.
