This the home page is a placeholder for a draft of the ToIP Trust Registry Protocol TSS (ToIP Standard Specification), a proposed Draft Deliverable of the TSWG developed by the Trust Registry Task Force. The drafting The Working Draft of this specification will proceed through three stages:

  1. Google doc: For ease of drafting and commenting during the early Draft Deliverable stage, the spec is initially starting as this Google doc <LINK TO BE ADDED ONCE PERMISSONS ARE CHANGED>. <== THIS IS THE CURRENT DRAFT FOR REVIEW.REVIEWS AND CONTRIBUTIONS
  2. Wiki page: Once the Google doc version of the spec is reasonably stable, it will move here to this page for final review and approval as a Working Group Approved Deliverable.
  3. GitHub Markdown file: content of the TSS prior to moving the document into a GitHub repo (where it  Once we reach a call for consensus on a Working Group Approved Deliverable, the spec will be converted into a Markdown document )and moved into a ToIP GitHub repo.

The following contributors each certify that they meet this requirement:

As with all layers of the ToIP stack, the purpose of a TSS 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.
