The High Assurance VID Task Force (HAVTF) is a task force of the ToIP Technology Stack Working Group, which will explore how to bridge . Its mission is to create a specification and implementation guidance for how the controller of a verifiable identifier (VID) can enable greater assurance in the integrity of that VID though mechanisms that enable the controller to bridge across different:
“VID Flavours”: including VID flavours—including Decentralized Identifiers (DIDs), X.509 certificates and the Domain Name System (DNS) records) with high records—to provide both higher cryptographic assurance and strong stronger semantic linkage; and,
“Trust Realms”: including how contrasting approaches to VID-based trust architecture can share common “Roots” of trust to establish interoperability between “trust realms”.
Through strong linkage between these different VID approaches, the Task Force intends to establish a foundation for establishing profiles for High Assurance (HA) Trust Registries, Governance Frameworks and Digital Credential Ecosystems that are agnostic to the underling VID used.
...
Trust realms (aka trust domains) so the same VID can be verified from more than one trust roots to increase human trust and enhance interoperability.
This “bridged approach” to VIDs will lay the foundation for High Assurance (HA) VID Profiles that can work with many different types of VIDs. This approach allows decision-makers to choose the most suitable VID for specific contexts and purposes without foregoing interoperability between VID systems. Below is one example of how such an HA VID identifying an example company could be deployed based on a DID, a DNSSEC record (following the High Assurance DIDs with DNS RFC), and an X.509 digital certificate containing an LEI (following ISO 17442 Part 2).
...
By designing a framework that supports and acknowledges theunique benefits of each VID flavour, different flavours can co-exist rather than compete. This results should result in a more robust, scalable, flexible and High Assurance high assurance architecture for VIDs that enable ToIP ecosystems to select the best VID for the specific context and purpose, without forgoing interoperability with other VID systemsthe implementation of ToIP digital trust ecosystems.

...
The deliverable of this Task Force is the High Assurance VID Specification, intended to create common patterns for establishing trust between different “VID Flavours”VID flavours. Accordingly, a VID must meet the requirements of a Verifiable Identifier (VID) as specified in the ToIP Technology Architecture V1.0 Specification and the draft ToIP Trust Spanning Protocol Specification. The requirements in this specification must interoperate with other ToIP component specifications as explained in the Evolution of the ToIP Stack.
