Key Facts

  • Academic credentials were used as the test documents in a controlled sandbox.
  • The pilot found interoperability requires only alignment on common protocols and trust architecture mappings, not a single shared framework.
  • It built on an April 2024 Memorandum of Cooperation; mutual recognition and legal trust frameworks remain the main hurdles.

Card Text

Wallet interoperability across legal regimes is harder than the protocol work suggests, because trust registries encode who may issue what under which law. The pilot's own conclusion makes the point: the technical exchange worked, and what remains unsolved is giving a foreign credential legal standing.
