Satoshi developed a hashing algorithm in Bitcoin which saw GPUs dominate it, forcing CPU users to the dustbin and making it a lot more difficult for everyone to mine Bitcoin. Out of this grew the GPU farms and the Bitcoin mining community.
The hashing algorithm I developed for SolidCoin v2.0 was designed to equalize CPU and GPU, to make them comparable watt for watt. Now SolidCoin would let anyone with a GPU (even NVIDIA ones) or CPU able to mine rather fairly.
SolidCoin is now the current technical leader of cryptocurrencies, with the most innovations and the
most secure p2p currency, if you want an early alpha for GPU mining please visit our forum.
