** Verification API - Communication channels and framework to support badge verification (was this badge issued to this person on this date? Has it expired? etc.)
** Endorsement API - Communication channels and framework to support badge endorsement (was this badge signed? is the signature valid? n.b. Endorsement employs the same signing mechanism as Badge Verification)
