Since there are already a lot of myths on the Internet and scientists dealing with this problem, there are also a certain number of charlatans who use the moment to earn money and fame.

World Community Grid: Join the Distributed Computing network!

There are about 650 million personal computers in the world, and most of them use only a small part of their power when working. At the same time, these untapped resources can be used for the benefit of all mankind. To this end, in 2004, the World Community Grid system was created – the largest global computing system for solving the most important humanitarian problems.
