We proposed a holographic dark energy model from Ricci scalar. We find the model does not only avoid the causality problem and is phonologically viable, but also naturally solves the coincidence problem of dark energy. We obtained the dilaton black-hole solutions in the background of the de Sitter or anti–de Sitter
universe, with the combination of three Liouville-type dilaton potentials.
