The proof of work stuff feels so cryptocurrency adjacent that I've been looking at other tools for my own thing, but I've seen Anubis on other websites and it seems to do a good job.
Also: Anubis does not mine cryptocurrency. Proof of work is easy to validate on the server and economically scales poorly in the wild for abusive scrapers.
If you have suggestions for JS based challenges that don't become a case of "read the source code to figure out how to make playwright lie", I'm all ears for the ideas :)
This unsubstantiated anti-cryptocurrency bias on HN is quite disappointing. Did you hear about filecoin, which allows to buy and sell disk space independently on large companies? Why wouldn't an anonymous cryptocurrency like Monero help with this real problem? What would the downsides be?
