If you read, I stated that
Sure, the VERIFICATION of blocks and transactions is decentralized, CONFIRMS are not. Confirms are when blocks confirm each other in the hashchain.
Because only 1 address can actually get the coinbase (anything else is disallowed) that means that only 1 address can confirm blocks. When you confirm a block, you verify transactions inside. Edit:
block you verify
In this case, verify meaning that the validity of the transaction in the block is accurate. Not just the hash of the transaction.
Prove that only central node can confirm/authorize transactions and you get the bounty.
Hence from my previous statement, the central node (according to the blockchain; since the authenticity of anyone else mining on the address CANNOT be made,) is the only node that can confirm blocks and transactions.
As far as I am concerned, this coin is not minable, and you are renting your hashrate to a pool, which as far as I can tell, is not trustworthy.
