Ethereum was pretty successfully ASIC-resistant. Other PoW algorithms are GPU-resistant. Even so, I doubt most spammers are sophisticated enough to create ASICs

Ethereum was pretty successfully ASIC-resistant. Other PoW algorithms are GPU-resistant. Even so, I doubt most spammers are sophisticated enough to create ASICs just to make cheaper requests to this guy's service.
- DannyBee 3y agoRight - the argument here seems totally silly. The cost barrier to entry would be incredibly high. Unlike blockchain systems, the implementation details of mcaptcha are also totally hidden, and you don't have to maintain compatibility at all. Someone creates an asic? Great, you can make it not work anymore without affecting any of your users for real. 10+ million down the drain.
