In this contribution we present the achievements of the CUORE
experiment so far. It is the first tonne-scale bolometric detector and it is in stable
data taking since 2018. We reached to collect about 1800 kg×yr of exposure of
which more than 1ton×year have been analysed. The CUORE detector is meant
to search for the neutrinoless double β decay (0νββ) of the 130Te isotope. This is
a beyond Standard Model process which could establish the nature of the neutrino
to be Dirac or a Majorana particle. It is an alternative mode of the two-neutrinos
double β decay, a rare decay which have been precisely measured by CUORE in
the 130Te. We found no evidence of the 0νββ and we set a Bayesian lower limit
of 2.2×1025yr on its half-life. The expertise achieved by CUORE set a milestone
for any future bolometric detector, including CUPID, which is the planned next
generation experiment searching for 0νββ with scintillating bolometers
