Drawing on my experience co-founding .TRAVEL, where we established a similar model, this post on Circle ID discusses a mechanism by which the ICANN Government Advisory Committee (GAC) safeguard advice for protecting the public interest attached to regulated sectors can be implemented. This approach would assure that as Internet users interact with domains at new "sensitive string" gTLDs associated with regulated industries and professions, they can be assured that the registrants are bona fide entities engaged in legitimate activities.
