  In this paper we model a game such that all strategies are non-revealing,
with imperfect recall and incomplete information. We also introduce a modified
sliding-block code as a linear transformation which generates common knowledge
of how informed a player is. Ultimately, we see that between two players in a
zero-knowledge game where both players are informed, the utility of trust is
established in the mixed strategy Nash equilibrium. A zero-knowledge game is
one of trust and soundness, placing utility in being informed. For any player
who may be uninformed, such players reveal they are uninformed.
