Fink is a broker designed to enable science with large time-domain alert
streams such as the one from the upcoming Vera C. Rubin Observatory Legacy
Survey of Space and Time (LSST). It exhibits traditional astronomy broker
features such as automatised ingestion, annotation, selection and
redistribution of promising alerts for transient science. It is also designed
to go beyond traditional broker features by providing real-time transient
classification which is continuously improved by using state-of-the-art Deep
Learning and Adaptive Learning techniques. These evolving added values will
enable more accurate scientific output from LSST photometric data for diverse
science cases while also leading to a higher incidence of new discoveries which
shall accompany the evolution of the survey. In this paper we introduce Fink,
its science motivation, architecture and current status including first science
verification cases using the Zwicky Transient Facility alert stream.
