Maybe submitting it to a popular journal is not a bad idea. Which ones would you recommend for this kind of innovation?
I'm not researcher or have degree on this field, so honestly i've no idea.
The competition between multiple ISPs across one country is not so bad as long as anyone with few dozen kUSD can start his own. Because prices across country are to some extent uniform, it helps decentralisation. And there is no waste here - bandwidth can later on be used for good things.
Assuming ISP decide to compete. With very few competitor with similar background, it's possible they decide to work together and partially control the network.
Suppose running an ISP in order to compete for block production costs few dozen kUSD. When the blockchain starts, it's not those few already existing ISPs that will be source of decentralisation, but the newcomers that want to compete. Just like, when Bitcoin started, many new entrants started to invest in mining and not the few supercomputers that already existed. As there is an opportunity, there will be new entrants. That those new entrants will collude is just as possible with this solution as with Bitcoin - except no special advantage can be gained by any particular player by optimising hardware (no application specific hardware could possibly apply to this solution) or by cheap electricity (irrelevant here). Because competition is restrained to a particular country (for example) prices and conditions are very similar for all competitiors.
