OpenCL, CUDA, C, HashCash

In Progress

Hi Freelancer Coders.

I am looking for help in implementing the HashCash proof of work algorithm (as used in Bitcoin) but instead of the core application running on a CPU, I wish it be run on the multiple streams of a GPU.

The original application can be found at [url removed, login to view] - [url removed, login to view] and it is likely to require a transformation of the SHA1 algorithm to use OpenCL (Or possibly CUDA) by taking that application and adapting it for parallel useage.

if you are able to help and have specific knowledge in using CUDA or OpenCL in this manner then please get in touch,.
