The mission of  the TSWG Technical Architecture Task Force (TATF) is to draft a TSS (ToIP Standard Specification) that defines the overall technical requirements for the four layers of the ToIP stack. This TF will be specifically focused on adapting the current version of the Hyperledger RFC defining the ToIP stack to become our foundational TSS. Note: this TSS is intended to serve as a direct a counterpart to the ToIP Governance Architecture TSS deliverable from the GSWG Governance Architecture TF.


  1. ToIP Technical Architecture TSS—a specification of the overall architectural requirements for each of the four layers of the ToIP stack and how they are abstracted from the layer below. It is anticipated that this TSS will lay the overarching foundation for four more future TSS—one for each layer of the stack—that will specify detailed interoperability requirements for each layer.
