There is a difference between closed source and not released to public .. If he hadn't said anything about it noone would care or talk about this.
We have been talking about the GPU miner from the start. Concerns were voiced that a malicious coder would create a private GPU miner without releasing it.
hey Crypto_Zoidberg I'm a fan of your project.
I think the cryptonote system addresses some of the major concerns of bitcoin and its derivatives. I also appreciate the changes to the cryptonote system found in your system. I've been wanting to mine since launch but the windows disadvantage has put me off permanently

I do see the efficacy of the scratchpad based hashing in the future if it grows 90MB a year. For now this doesn't even really begin to tax GPU's with 6GB of ram. Basically with 6GB ram a GPU and a 90mb blockchain, you could perform 66 hashing functions concurrently yes? With a 180mb blockchain 33, with a 270mb blockchain 22, etc etc.
I also see how producing an ASIC with ever-increasing CPUs would be wasteful, as the amount of them that can actually work is wholly dependent on the RAM, the amount of these CPUs available to hash would be reduced by a large step each year. Basically,
whats the point in having a ASIC that can perform 2000 hashing functions concurrently when you only have enough ram to do 20 or 30.
However I don't believe that was indicated and explained in a clear and precise manner.It does seem that in order to aid fairness, we should actually be focusing on producing a GPU miner now and as soon as possible. This would prevent a malicious coder creating one in secret and obtaining an unfair advantage.
Once we take that step to GPU mining, the playing field will be even and we know that ASICs will never be developed (as they are pointless in this scenario by design). Once that GPU miner is created the road will be paved and we can all be sure that no one has an unfair advantage.
As it stands, GPU mining will be more efficient than CPU mining for... 8.333 years.This is a lot of time in the cryptocurrency world.Until a GPU miner is created, we will always be wondering if someone else has one, and for good reason (66x efficiency? yes please!)
I don't know why it's acceptable to everyone that someone is mining half the coins because they have an unfair advantage. Even if it's ethical, it is not in anyone's best interest except the GPU miner.
