Mission

The Trust Spanning Protocol Task Force (TSPTF) is a task force of the ToIP Technology Stack Working Group. The mission of the TSWG is to draft the ToIP Trust Spanning Protocol V1.0 Specification to meet the requirements for ToIP Layer 2 as specified in the ToIP Technology Architecture V1.0 Specification. Since this protocol is the keystone for interoperability of the ToIP stack, the TSPTF intends to reach out across all other orgs in the space (e.g., Decentralized Identity Foundation, Hyperledger, OpenWallet Foundation, W3C Credentials Community Group) for collaboration on this effort.

For a complete overview of the development process for the ToIP technology stack, see Evolution of the ToIP Stack. See also this ToIP blog post announcing the launch of this new task force.

Deliverables

The deliverable of this Task Force is the ToIP Trust Spanning Protocol Specification that must meet the 18 requirements for the ToIP Layer 2 protocol as specified in the ToIP Technology Architecture V1.0 Specification. The requirements in this specification must interoperate with other ToIP component specifications as explained in the Evolution of the ToIP Stack.

At the 2024-05-24 special meeting of the TSWG, a second deliverable was requested of the TSPTF: a VID Appraisability Framework for assessing the security characteristics and trust basis for a verifiable identifier (VID).

Milestones

A first Implementers Draft of the ToIP Trust Spanning Protocol V1.0 Specification was announced in this ToIP blog post. The goal of the TSPTF is now to advance that Implementers Draft based on implementation feedback to the point where we can announce a Public Review Draft by the end of 2024.
