I assume you are referring to Folding@Home, which is a very similar project to the BOINC/Gridcoin system but is rewarded with Curecoin instead. Unlike BOINC, which spreads research compute across many different projects, Folding@Home focuses all its compute on folding protein structures.

Both projects are dear to me, as they allow the crypto-sphere to benefit computational science.

Be careful with Google Searching 'Cloud Folding' as you will be presented with several middle men that offer to fold proteins for you (yielding you Curecoin) in exchange for payment. They do this to skim profits. If you want to start with Curecoin, go to the official website and start folding in your browser (CPU only - slow) or download the full client (CPU and GPU - fast).
