Again thank you for trying but if it cannot be explained in very basic, layman's terms, it is a waste of time and effort.
No it isn't. Try explaining how email works to a layman in the 90's. This tech right now is not aimed at laymen.

I disagree: Explaining e-mail in layman's terms in the 90's, even the 1890's, couldn't have been simpler: Just like regular mail, only instant. They surely wouldn't have understood how it was possible but would immediately have understood what it actually does.
I'll go further and explain to you something maybe possible in the future that is not possible now and I am sure you will understand: Teletransportation. It's like flying from one place to another only without having to leave the current position to get to the new one. It is simple and clear enough.
What I am asking is exactly which current activity, or service, in whatever environment, be it individual, a company or a nation, can be vastly, evidently to anyone -AND VIABLY- improved by the usage of these childchains, in practical, current purposes of situations. And I offered an example that, apparently, is already in use (by Democracy Now). If you don't know, I'd appreciate if you don't contribute to the confusion. Otherwise, I'd appreciate any real knowledge. Thanks.
