\cite{Taleb_2013} explains that the natural selection of an evolutionary process is particularly antifragile, since a more volatile environment increases the survival rate of robust species and eliminates those whose superiority over other species is highly dependent on environmental parameters.
We could use temporal correlations in blockchain traffic to gauge the response of a given object (e.g. fees) to the volatility of an external stressor that affects it, but another approach is to simply study the response of market
