This coin was on my radar, then I did some investigating.

Because of this: https://github.com/MidasPaymentLTD/midascoin/blob/master/src/main.cpp#L1778
This disallows ANY pool or solo miner from using their own address for a block to be accepted.

Now, skip ahead to here: https://github.com/MidasPaymentLTD/midascoin/blob/master/src/main.cpp#L4290
You CAN mine, but it wont matter what address you or the pool uses, it will automatically go to the 'tax address.'

Now, this is NOT decentralized. Sure, the VERIFICATION of blocks and transactions is decentralized, CONFIRMS are not. Confirms are when blocks confirm each other in the hashchain.

Since you cannot have a different publickey for an address to generate a block (or have it be accepted by the network at any rate) block generation is centralized.
