If that happens, count with me to use Anubis to factor large primes or whatever science needs as a background task.

Actually, that is not a bad idea. @xena maybe Anubis v2 could make the client participate in some sort of SETI@HOME project, creating the biggest distributed cluster ever created :-D

Oh come now, clearly Anubis should make the clients mine bitcoin as proof of work, with a split for the website and the author.

Oh dear, somebody is going to implement this in about an hour, aren't they....

Just in case you didn't know, cryptominers in Javascript are already thing. Firefox even blocks them.

a service that allows you expose and host your data in a private manner getting a cut from whatever token your endpoints have generated.

Shouldn't you factor composite numbers? Factoring prime numbers is pointless.
