And where did you get that information? Who said anything about a centralized blockchain?
If you read up on the "White paper" (and also this thread a few pages ago) it states that the transactions on the blockchain for hashcoin will be controlled by gaw/prime controllers.
Well this is the relevant part of the withe paper that talks about Primer Controllers
Prime Controller
The Controllers on the HashCoin network are the backbone of the system which enables Transactional Immutability to occur and be confirmed within a near-instantaneous response timeframe. Controllers exist in the peer-to-peer network to assist in the speed of the transactional locking that occurs as part of the Transactional Immutability capabilities of HashCoin. These Controllers interact with HashCoin client nodes in a swarming peer-to-peer environment and receives instructions and verifications through the Prime Controller that presides and protects the integrity of the network and blockchain.
The Prime Controller serves multiple purposes in its goal of protecting the integrity of HashCoin’s network. First, the Prime Controller exists to perform archival functions on the HybridFlex Blockchain. Second, the Prime Controller exists to provide the swarming Controllers and the HashCoin client nodes with the reconciliation instructions for all verified and confirmed transactions. Future functionalities of the Prime Controller will be discussed in a future Prime Controller whitepaper.
So for me the bolded text suggest that this is not centralized. It suggest that they are spread over the peer-to-peer network probably not unlike Nodes in the bitcoin network.
Look, I know you're probably not a troll, and you're trying to make sense of this whitepaper. That being said, (and don't take this personally) you are pretty wrong on the decentralized aspect of hashcoin. Prime controllers are
all owned and operated by GAW (just like regular hashlets). Sure, you might be able to purchase them on the cloud, but the miners are, in the end, physically in GAW's hands. Trusted nodes ("Prime Controllers") are then given the power to instantly confirm transactions (that's how they get around the trustless doublespend problem, by adding trust to the system). Who determines which nodes are trusted? GAW. This is an awful lot like Stellar (another altcoin), which has near-instant confirms at the expensive of decentralization, because the developers pick the trusted nodes. You can see that there at least is
some centralization going on here, unlike bitcoin, which is completely trustless.
But wait, there's more!
In the whitepaper, we also have the "hybridflex" blockchain. The system the whitepaper describes is simple: GAW has the copy of the blockchain, and clients access the remotely hosted blockchain to determine user balance--this is a lot like the electrum or multibit bitcoin wallets. However,
it will be built into the core client, IE GAW is the only entity with an actual copy of the blockchain. This forces users to trust GAWs copy of the blockchain (as running your own full node is no longer allowed). This is where things get sketchy...
That means that GAW can simply omit blocks it doesn't like because they control all the nodes. Note that this type of attack is impossible with bitcoin because the blockchain is distributed: if anyone tried to omit a block it would cause a "fork" the blockchain, and the side with the greatest hashpower would determine which version is correct.
If you have any questions about this stuff, or if you disagree, shoot me a response. But please keep it civil!
