Why does reward have to proportionate to hash power? E.g. have it more of a "Lottery" with Miners than "who solves this mathematical problem first". This way there is incentive to use the "lightest" or most "power efficient" devices, while still keeping to the (at least I thought) goal of "everyone being equal".  This may kill pools, but IMO they aren't helping the distribution of the Magi network, just consolidating it into various entities.

Wouldn't it be nice if a Pi 0 could "mine" (and get a reward)? For $20 I can make one that is solar powered, network connected, and a battery backup.

Maybe make block time / rewards equal to the number of nodes supporting the network? The more nodes, the higher the rewards across the network?
