Abstract.In this paper we give a full view on the proof of Riemann's Hypothesis for Goss zeta function in characteristic $p>0$. First, we present the set up of the problem. Then, we analyze the proof of J. Diaz-Vargas for the $q=p$ case. Next, we discuss the main ideas of the unpublished note of B. Poonen for the case $q=4$ from a combinatorial point of view and how this ideas cannot be extended to more general cases. Finally we give an overview on how J. Sheats proves the general case.
