Must be developed --- I strongly believe that new protocols must be developed, even though protocols have worked so far, new technology has been arising and protocols have been adapting to it instead of putting a thought in creating something new that would serve for the technology to come and build it from the scratch.

For this you can involve multiple states and stakeholders so the power won't reside in a single entity.
