This paper gives a reasonably rigorous mathematical treatment of the growing block model in the Newtonian, relativistic and causal set contexts. Also see this paper for a discussion of whether quantum gravity offers brighter prospects for A-theory than classical relativity. Let me know if you’d like ungated versions of either of these.
