Resumen en inglés We show that the gravitational waves measurements have raised the opportunity to measure H 0 with dark sirens to within 2σ, the accuracy required to resolve the Hubble-Lemaître tension. There are two principal reasons for our results: (1) upgrades to GW LIGO-Virgo transient catalogues GWTC-1 and GWTC-2 enhance their sensitive with only 10% of contamination fraction, and (2) new dark sirens should help to constrain our dynamical EoS. In conjunction, sensitivity upgrades and a new dark energy model will facilitate an accurate inference of the Hubble-Lemaître constant H 0 to better with an ±0.077 error in comparison to the LIGO dark siren with +14.0/-7.0, which would further solidify the role of dark sirens in late dark energy for precision cosmology in the future
