  We study a holographic construction of conformal blocks in the Regge limit of
four-point scalar correlation functions by using coordinates of the two-sided
Rindler-AdS black hole. As a generalization of geodesic Witten diagrams, we
construct diagrams with four external scalar fields in the Rindler-AdS black
hole by integrating over two half-geodesics between the centers of Penrose
diagrams and points at the AdS boundary. We demonstrate that late-time
behaviors of the diagrams coincide with the Regge behaviors of conformal
blocks. We also point out their relevance with the pole-skipping phenomena by
showing that the near-horizon analysis of symmetric traceless fields with any
integer spin in the Rindler-AdS black hole can capture the Regge behaviors of
conformal blocks.
