  As simulating complex biological processes become more important for modern
medicine, new ways to compute this increasingly challenging data are necessary.
In this paper, one of the most extensive volunteer-based distributed computing
systems, called folding@home, is analyzed, and a trust-based approach is
developed based upon it. Afterward, all advantages and disadvantages are
presented. This approach uses trusted communities that are a subset of all
available clients where they trust each other. Using such TCs, the system
becomes more organic and responds better to malicious or malfunctioning
clients.
