Afaics his abstract paper does not deal with some of the intricacies of the economics that have to be solved in order to make the design actually work in the real world.

You see that often in unseasoned theorists.

Someone asked me in a PM for my opinion of VanillaCoin. I just expended 15 minutes studying it for the first time:

The DarkPP stuff is vaporware and no details are available.

It claims some efficiency improvements over Bitcoin and Peercoin. Appears the developer is a seasoned P2P networking programmer. If I had to venture a guess, he probably was a former developer of a Bittorrent client.

The main feature of significance is the zero confirmation time research which attempts to gain a faster consensus. Unfortunately he seems to entirely forget any game theory analysis. The Byzantine fault tolerance in proof-of-work consensus is due to game theory incentives given by the proof-of-work rewards. He expects these peers to behave a certain optimum way when they are not being paid to do so. Many faults will be found in his design because of this. I don't have time to go outline the faults.

Satoshi was a lot more astute than many people might realize. If you are going to improve upon Satoshi's work, you need to be very sharp.

To those wondering if double spend is possible, a bounty is available. Could probably be paid in BTC if preferred.

My reply there, please go there for further discussion and their rebuttal:

How much is the bounty?

Will it pay out if I just tell you how it can be done?

It is pretty simple actually. Bribe some nodes by sharing some of the double-spend theft.

There is created an incentive to aggregate mining power in order to sell capacity to double-spend. It is an economics issue. Just because it can't be accomplished on the controlled testnet is irrelevant.
