This is very exciting. Here is the APK I downloaded. And the associated discussion.

It even already seems to support stylus input which is very exciting seeing as there has been talk of porting RNote to Android.

Do you understand how Proof-of-Work works? Perhaps you can give me an ELI5 that shows that it does not use the client's CPU to perform calculations for only the purpose of proving that the client's CPU performed the calculations?

    I do, yes, you are just too crypto-focused. Anubis uses the result of the PoW to fingerprint, I.E. to do a job greater than just the calculation. It's also an extremely efficient alg. I won't read the docs for you, but feel free to read them first if you would like to discuss it further.

    It's also an extremely efficient alg.

    Not if it's an effective proof-of-work anti-scraping mechanism. The point of these are to make it prohibitively expensive for scrapers to harvest data.

    A mire energy efficient way to do this is with lags and tar pits, which do not cause CPU cycles to be wasted.

    Any mechanism - any - that uses proof-of-work is by definition wasting CPU cycles. If there's a useful waste product, like boinc, where the work that's proved to be done is science, then the POW isn't pure waste energy. There are certainly more efficient ways of generating fingerprints than PoW; Google and Facebook are peerless at fingerprinting without any PoW at all. The value of these fingerprint coins tokens is entirely incidental to the real purpose: to cost the scraper CPU cycles, cost them energy, and make scraping less profitable.

    Anubis is all of the execution cost of cryptocurrency, without the financial flavoring.
