What assumption then does DCKR make for derivation of asymmetry? It assumes time travel is not possible. If anyone invents a time machine, we might have to reassess utility of DCKR as well.

(DCKR further relies on a cryptographic hash function, so irreversibility of that hash function is also necessary. But we generally rely on existence of such a function anyhow, so the goal is to not introduce

*additional*attack points into such systems. Also, we have a larger number of hash functions to choose from - so we can more readily swap out one function for another should a vulnerability be found.)
