- woodruffw 4y agoYes, I am. I'm not aware of a threat model in which you can't trust the frequencies GPS is on but you can trust the frequencies that the FCC allows personal radio transmissions to be on. Seems like a lot of added complexity (and, notably, no legal recourse) for essentially the same failure mode.

- woodruffw 4y agoYes, GPS is not particularly secure. But I don't think that addresses the threat model above. (In general, jamming is always a possibility with anything wireless. That is just not going to change. What might change is spoof resistance, which can be accomplished with schemes that are a lot simpler than anything DeFi can conjure. There's a decent amount of work on related schemes in the vehicle-to-vehicle communication space.)
