Hey, I have an idea!

PROOF-OF-WORK DDOS PROTECTION

Say, you have a website that is being DDOSed. Instead of CAPTCHA, you can put a script on it to mine some Yescrypt coin (CPU-only) shares before opening access to the site (or do other things needing spam protection). Of course, you can adjust difficulty depending on DDOS volume and your greed.

For a normal user this will take a few seconds on an average PC. No more annoying CAPTCHAs, just wait a bit. For a DDOSer this will be a pain. Moreover, DDOSer will mine coins for you! DDOS will give profits to website owners, with no more paid subscription to Cloudfare.

IMHO this idea will lead CPU altcoins to the top!
