The best thing is that with pizza there are no forks involved.

But the question is: how many slices would be enough to make it decentralized? There's only so much pizza to go around per slice, and if the slices become too small, the diners are no longer incentivized to keep going.

And what about governance? Who decides who gets the biggest slice? I know from experience that solving this issue can be more problematic than solving the byzantine's general's problem
