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.

i wrote a bit about it here: https://capjs.js.org/guide/effectiveness.html

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.
tiagozip

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"
