Centralized altcoin mining question

[blueapple]

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.

Have not done much research into centralized mining but closest thing I've heard was Ripple so maybe look into that for more info?

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.

Ripple does not mine, but is decentralized...

If you want centralized altcoins there was one a few years back with a similar approach to PoS (Realcoin or something like that?). Most centralized solutions seem to be pegged to USD, EUR etc. though.

LindenDollars (SLL) are also some centralized altcoins, but there is no source code available for them.
