For 21 years, millions of volunteers let UC Berkeley use their home computers to search the sky for alien signals, producing 12 billion detections — after a decade of filtering, scientists narrowed them to roughly 100 targets worth a second look.

SETI@home’s 12 billion threshold events became roughly 100 FAST follow-up targets after interference filtering, blind synthetic-signal tests and manual review.
