Background
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.
Objectives
The primary objective of this Task this Task Force is to develop the the ToIP Trust Registry Protocol as a ToIP Specification. The purpose of this deliverable to enable interoperability between ToIP-compliant trust registries.
...
Context
The mission of the ToIP Foundation is to define a complete architecture for Internet-scale digital trust that combines cryptographic trust at the machine layer with human trust at the business, legal, and social layers. The ToIP stack has two parallel halves—a technical stack and a governance stack—operating at four layers 1) Utility (DLT Blockchain), 2) Agent/Wallet, 3) Credential Exchange (Issuer/Verifier/Holder) and 4) Ecosystem (Application). See further details in the ToIP white paper.
...
As with all layers of the ToIP stack, the purpose of a ToIP specification is to enable the technical interoperability necessary to support transitive trust across different trust communities implementing the ToIP stack. In this case, the desired interoperability outcome is a common protocol that works between any number of decentralized trust registries operated by independent governing authorities representing multiple legal and business jurisdictions. One specific example of this need is the digital trust ecosystem defined by the Interoperability Working Group for Good Health Pass (GHP). The GHP Trust Registries Drafting Group produced an extensive set of recommended requirements for a GHP-compliant trust registry.

Note that this specification is initially being drafted as a Google doc which will then migrate to this wiki and finally move into GitHub for final publication.
- OpenAPI 3.0 API - managed in GitHub.
- X.509 DID Interop concept.
...
- Publication of the first Draft Deliverable as a ToIP wiki pagevia a GitHub repo.
- Publication of the final Draft Deliverable.
- Approval of the Draft Deliverable as a Working Group Approved Deliverable.

Meeting Schedule and Notes
The first meeting of this Task Force will be Thursday 17 June 2021 at 07:00-8:00 PT / 14:00-15:00 UTC. The Zoom link is available on the ToIP Calendar. At the first meeting we will decide on a regular meeting schedule (which may be multiple times a week to complete a spec quickly)TRTF holds two meetings — one on NA/EU time zones and one for APAC time zones — every Thursday. Please see the ToIP Calendar for the exact meeting times and Zoom links.
