  We propose a new class of tensor network state as a model for the AdS/CFT
correspondence and holography. This class is demonstrated to retain key
features of the multi-scale entanglement renormalization ansatz (MERA), in that
they describe quantum states with algebraic correlation functions, have free
variational parameters, and are efficiently contractible. Yet, unlike MERA,
they are built according to a uniform tiling of hyperbolic space, without
inherent directionality or preferred locations in the holographic bulk, and
thus circumvent key arguments made against the MERA as a model for AdS/CFT.
Novel holographic features of this tensor network class are examined, such as
an equivalence between the causal cones C(R) and the entanglement wedges E(R)
of connected boundary regions R.
