The Technology Stack Working Group and its Taskforces incubate, design, test and recommend for adoption the components and combinations of technical elements that span all four layers of the ToIP stack and comprise a complete, interoperable instance of the model.


Define (directly or by reference) the technical standards, test suites, and interoperability certification standards for the Trust over IP architecture stack as defined in Hyperledger Aries RFC 0289 (or its successor as identified in the RFC document itself).



US/EU: meetings are held bi-weekly, every second (TBC)
