BULLKID is an innovative cryogenic particle detector to search for low-energy nuclear recoils at the 100 eV energy scale.
It consist of an array of 60 silicon absorbers of 0.3 g each sensed by phonon-mediated, microwave-multiplexed Kinetic Inductance Detectors.
The total active mass is 20 g but the tecnology is designed to be easily scalable to 1 kg. 
BULLKID's unique feature consists in being a fully active array, thanks to the lack of supports for each unit.
This enables volume fiducialization and allows background rejection down to the lowest detectable energies, a key requirement for experiments on low-mass Dark Matter.
In this talk I will present our new and promising results, and the prospects for a future experiment.
