Bots can now solve CAPTCHAs better than humans
(calckey.world)
This is a most excellent place for technology news and articles.
Proof of work. This won't stop all bots from getting into the system, but it will prevent large numbers of them from doing so.
Proof of work could be easily combined with this, if the wasted computational cost is deemed necessary/worthy. (At least it's wasted CPU cost, instead of wasted human time like captcha.)
Tor has already implemented proof of work to protect onion services and from everything I can tell it has definitely helped. It's a slight inconvenience for users but it becomes very expensive very quickly for bot farms.
Yeah proof of something (work, storage, etc) seems like the most promising direction... I think it's definitely going to raise global energy consumption further though which kind of sucks.
I don't think that raising global energy is necessarily a bad thing. I think that that will lead to the development of more energy technology.
