Anoncoin will use I2P and coin mix services to grant anonymous transactions. DarkCoin promise an "encrypted transaction network" and "coinjoin" technology for anonymous blockchain. For me booth approaches are not soo different.

I would suggest that DarkCoin should use the TOR network to hide mining and transactions, since it is more reliable than i2p and much more mature. There is no point in reinventing the wheel, when reliable approaches exist.

IMHO it would be great if the DarkCoin miner and wallet software implements or interacts tightly with TOR. So that each miner and wallet will be part of the TOR network, providing a TOR relay to strength the network and anonymity.

I would suggest that all the cloud miners out there configure their VM's to be TOR relays while mining ... actually thats what i am doing.

Thanks for the info.  Any idea how long until Darkcoin anonymity features are up and running?  Is there an ETA?

If more people are interested I could work on GPU miner for a bounty. I already have something more or less working (pools are accepting shares, also solo-mined one block this night with it), but it's still very slow (nearly 2 MH/s on Radeon R9 290). Unfortunately I can't promise it will get much faster, still working on possible optimizations.

I add this to my suggestions along with my initial pitchdark. the chain suffix is very recognizable for cryptocurrencies whilst maintaining the darkcoin brand.

FYI

I'll match his 1000DRK

Why don't you want to keep it CPU-only?

Is it completely impossible to eliminate the possibility for GPU mining?
