Thanks, Sukrim.

Thanks PYneer. I believe Ripple does not allow any mining, other than using WCG processing donation.

Really curious about other altcoins that might use the decentralized sha256 or scrypt platforms that have implemented centralization on top. I can't seem to find any information on whether it's even possible to prevent solo mining and limit pooled mining to one centralized authority.

Are there any altcoins that have added centralization to their structure and prevented solo and/or third party mining pools? A coin that controls how, where and who mines?

Is this even possible?

Thanks.
