  In this paper we discuss to what extent one can infer details of the interior
structure of a black hole based on its horizon. Recalling that black hole
thermal properties are connected to the non-classical nature of gravity, we
circumvent the restrictions of the no hair theorem by postulating that the
black hole interior is singularity free due to violations of the usual energy
conditions. Further these conditions allow one to establish a one-to-one,
holographic projection between Planckian areal "bits" on the horizon and
"voxels", representing the gravitational degrees of freedom in the black hole
interior. We illustrate the repercussions of this idea by discussing an example
of the black hole interior consisting of a de Sitter core postulated to arise
from the local graviton quantum vacuum energy. It is shown that the black hole
entropy can emerge as the statistical entropy of a gas of voxels.
