It seems to me that this should be easily addressable with a proof-of-burn system (c.f. https://en.bitcoin.it/wiki/Proof_of_burn https://en.bitcoin.it/wiki/Proof_of_burn). This simulates the property of burning energy to have a chance of generating coins by instead burning coins to have a chance of generating coins (I don't think it's a pyramid scheme: rather, it'd incentivise burners to contribute to the network, just as miners are incentivised). Anyway, it's a very neat idea, and it'd make all this much more energy-efficient while still costing burners quite a lot (and hence making it expensive to try to attack the network).
