If the block spacetime model is used, there is no real motion.

For the apparent motion, the infinity representing the infinite steps in the Zeno’s paradox becomes a potential infinity, depending on how many divisions the observer wants to divide the spacetime into.

The calculus explanation of the Zeno’s paradox can be regarded as a potential infinity one, using the epsilon-delta definition of limit.

If spacetime is discrete, the Zeno’s paradox is no paradox. However, with the block spacetime model, whether spacetime is infinitely divisible is irrelevant.
