At the moment it is just an idea.
The idea is that customers can pay CPU-time for using websites or do any other things that DDOS or bruteforcer bots should not be able to do. Say, you need to solve a share that takes 5 seconds on average PC to login to Bitcointalk forum (instead of completing Recaptcha) - and difficulty can be increased if there is a reason to have more security.
This will not a problem for a normal user but it will be very hard and expensive for bots to take site down (DDOS purpose) or crack a password. Bots will have to complete mining shares for every try and will make money for site owner.
We need:
1. Javascript implementation for mining CPU altcoins (yescrypt, yescrypt16r, yescrypt32r etc).
2. Server-side implementation to serve the method.
This will advertise CPU altcoins and make people use them.
