Burned transaction fees, similar to a sales tax with a slight twist. Fees would ramp up in a similar way to Bitcoin, where the sooner you want to transact, the more it costs, and perhaps say a month out transactions are always free. I think there's something in that system where we could mint blocks weeks in advance, and this would keep the need for PoW to an absolute minimum.
