We introduce the concept of boundary rigidity for Gromov hyperbolic spaces. We show that a proper geodesic Gromov hyperbolic space with a pole is  boundary rigid if and only if its Gromov boundary is uniformly perfect. I will explain some of its applicatioins and explain the idea of the proof. This is joint work with Qingshan Zhou.
