(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.)
