I don’t know if “anything”. But surely people overestimate kits capabilities.

It’s only a PoW challenge. Any bot can execute a PoW challenge. For a smal to medium number of bots the energy difference it’s negligible.

Anubis it’s useful when millions of bots would want to attack a site. Then the energy difference of the PoW (specially because Anubis increase the challenge if there’s a big number of petitions) can be enough to make the attacker desist, or maybe it’s not enough, but at least then it’s doing something.

But most people it’s not getting attacked and getting ddos by millions of bots.
