Hedera Guardian 3.7.1 Release: Standardizing Sustainability with IWA dMRV 3.0

The latest release of GBBC member Hashgraph’s Hedera Guardian (v3.7.1) introduces enhanced schema templates designed to maintain policy consistency and reduce downstream authoring costs, including an upgrade to use GBBC's InterWork Alliance (IWA) digital Measurement, Reporting, and Verification (dMRV) 3.0 Framework.

IWA empowers organizations to adopt and use token-powered services in their day-to-day operations, across use cases and networks, bringing inclusivity to globally distributed applications.

Version 3.0 of the dMRV Framework introduces targeted but important updates that enhance the framework’s usability and scalability. The most significant change is the modularization of MRV Extensions into reusable Extension Sets. This enables third parties to independently digitize methodologies and contribute them back to the framework, reducing duplication and ensuring consistency. This will allow future projects using the same methodology to reuse previously created Extension Sets, saving time and resources while ensuring that two projects using the same methodology are using the same formulae and variables, promoting further interoperability and comparability across the ecosystem.
