I have a much better idea - how about we replace all money with sidechains!

Every restaurant in the world will create their own sidechain currency which they can mine via proof of cooking. Then customers pay by using the 2 way peg to buy some sidechain units from the restaurant, and the restaurant will cash out via the 2 way peg to pay their suppliers.

Or, even better, they will do atomic swaps for their own proof of cooking sidechain units for their supplier's proof of delivery sidechains or proof of plumbing sidechains.

This is so much better than just having money.

A whole new world of possibilities is upon is. We could invent the barter system again except improve it by adding trade barriers and a bunch of imaginary extra goods that aren't useful for anything but that people are required to trade with for some reason.
