History

BOINC was originally developed to manage the SETI@home project. The original SETI client was a non-BOINC software exclusively for SETI@home. It was one of the first

projects, and not designed with a high level of security. As a result, some participants in the project attempted to cheat the project to gain "credits", while others submitted entirely falsified work. BOINC was designed, in part, to combat these security breaches. The BOINC project started in February 2002, and its first version was released on April 10, 2002. The first BOINC-based project was Predictor@home, launched on June 9, 2004. In 2009, AQUA@home deployed multi-threaded CPU applications for the first time, followed by the first

application in 2010. As of 15 August 2022, there are 33 projects on the official list. There are also, however, BOINC projects not included on the official list. Each year, an international BOINC Workshop is hosted to increase collaboration among project administrators. In 2021, the workshop was hosted virtually. While not affiliated with BOINC officially, there have been several independent projects that reward BOINC users for their participation, including

Mobile application

A BOINC app also exists for Android, allowing every person owning an Android device – smartphone, tablet and/or Kindle – to share their unused computing power. The user is allowed to select the research projects they want to support, if it is in the app's available project list. By default, the application will allow computing only when the device is connected to a WiFi network, is being charged, and the battery has a charge of at least 90%. Some of these settings can be changed to users needs. Not all BOINC projects are available and some of the projects are not compatible with all versions of Android operating system or availability of work is intermittent. Currently available projects are Asteroids@home,

As of September 2021, the most recent version of the mobile application can only be downloaded from the BOINC website or the F-Droid repository as the official Google Play store does not allow downloading and running executables not signed by the app developer and each BOINC project has their own executable files.

Credit system

* The BOINC Credit System is designed to avoid bad hardware and cheating by validating results before granting credit. * The credit management system helps to ensure that users are returning results which are both statistically and scientifically accurate. * Online volunteer computing is a complicated and variable mix of long-term users, retiring users and new users with different personal aspirations.

Projects

BOINC is used by many groups and individuals. Some BOINC projects are based at universities and research labs while others are independent areas of research or interest.
