Since 2006, PrimeGrid has been home to many projects searching for primes. They started looking for primes of ascending size and storing them in a database accessible to anyone for download. These were relatively small primes in the range of about 10 digits. In February 2008, however, this sub-project was discontinued because this database has little benefit and you did not want to spend more time on another compilation. The second project looked for the largest known twin primate. This search was successful but continues to break the record. Today, many sub-projects are looking for special primes.

Positive: This project will publish the name of the primes finder, if desired!

The project awards for the individual subprojects badges.

The PrimeGrid team opposed the monetization of BOINC results as part of their own project, e.g. by GridCoin. This is to prevent fraud and wrong results. [1]
