Badges

Badges appear beside your name in message board posts and on your user page. They are given out automatically; there is nothing to apply for. The project's own badges are updated once an hour.

Credit

For your total credit. You hold one at a time: the highest level you have reached, which is replaced by the next when you pass it.

  • 1 millioncredits
  • 5 millioncredits
  • 10 millioncredits
  • 25 millioncredits
  • 50 millioncredits
  • 100 millioncredits
  • 500 millioncredits
  • 1 billioncredits

Scenarios' worth of work

For the work you have done, counted in scenarios. The Kessler@home simulation runs each scenario of the sweep with 400 seeds, and each of your valid tasks is one of those runs, so 400 valid tasks are one scenario's worth of work: the 1,000-scenario badge takes 400,000. You hold one at a time: the highest level you have reached.

A task counts once it has been validated and its result stored. Both volunteers whose results agreed get it. Tasks of every scenario count, the two beta tests included; tasks that failed or were found invalid don't.

Beta test

For everyone who returned a task from either of the two beta tests in November 2026, whatever its outcome. It is never taken away.

Recent average credit

BOINC's own badges, the same on many BOINC projects, for the top 1%, 5% and 25% of volunteers by recent average credit (among those with a recent average above 1). They are worked out once a day and change as your average does. Teams get the same three badges for the team's recent average credit.
