emusks impersonates browser fingerprints by default (https://emusks.tiago.zip/getting-started/configuration.html#...). as for logging in, you can get a token from your active browser session.

> a blue hat is typically associated with law enforcement in the US

what it's literally just the default emoji for cap

> lack of acknowledgement on your site (until now)

i've added a note

btw no, cap does not contribute to any "fed botnet". you can build the WASM binaries yourself and compare the hashes. added a clarification about that to the docs.

even at a huge scale the emissions are still extremely small.

> Also users may be at a disadvantage as JS crypto would not be optimized for PoW (for example lack parallel crypto capabilities or context switching between calls).

JS crypto is only used as a fallback, Rust WASM is used for solving.

added a note saying that to the docs, should hopefully clarify stuff a bit!

Yes, the code is open-source for you to check

Cap does not send any of the calculated hashes ANYWHERE, the white paper just details a bit how proof-of-work works and I thought that it would be interesting to share.

you can compare the hashes of the wasm lmao the build script is very much public

> how much more CO2 this is going to produce extremely minimal emissions, you're only solving a small cryptographic challenge after all.

scrapers usually don't render a webpage, else their scraping wouldn't be efficient at all.

yeah i also recommend trying out the invisible mode

anubis is more like Cap's checkpoint, but still the implementation is very different.

no, it's not mining crypto.

too late to change now :)

also i like how it's a reference to both CAPtcha and "no cap"
