Sure but certainly one could still make it costly enough to prohibit mass sending but not too costly to drain a cell battery under casual use. Or am I underestimating the level of complexity needed for a viable proof of work?
- idlewords 12y agoSomething lightweight enough to be feasible on a cell phone is likely enough to be trivially computable in bulk by a decent bit of hardware. Think about all those obsolete bitcoin miners out there.
- ch 12y agoIt sounds like proof-of-work alone is insufficient. The bit* type systems sound promising but that seems to preclude mobile. Interesting. What a funny problem we have built for ourselves. Interesting that SMS appears to have simply legislated the problem from existence (or so says the article), I suppose if anyone can connect to a telephony network for cheap the problem would persist there too.
