The ToIP Technology Stack WG originally created the TRTF in June 2021 in response to the market gap identified during the work on the Good Health Pass Interoperability Blueprint. The first-generation TRTF worked quickly to create a first-generation ToIP Trust Registry Protocol specification, which it published in September 2021 for community review. At that point, the attention of the TSWG moved to the Technology Architecture Task Force (TATF) to develop the ToIP Technology Architecture V1.0 Specification (TAS). With the publication of the first public review draft of the TAS in December 2022, and with market demand increasing for decentralized trust registries (aka trust lists), the TSWG started up the second generation of the TRTF in December 2022 to produce a complete, production-ready ToIP Trust Registry Protocol Specification that can then be submitted to a formal SDO such as ISO. Furthermore, as related work has is now underway at the Decentralized Identity Foundation, the second-generation TRTF will be working in collaboration with the DIF Claims and Credentials Working Group work on Trust Establishment. 

Objectives

The primary objective of this Task Force is to develop the ToIP Trust Registry Protocol as a ToIP Specification. The purpose of this deliverable to enable interoperability between ToIP-compliant trust registries.
