Renormalization‑group derivation for heterogeneous networks underlying universal cascade scaling
Establish a full renormalization‑group derivation for information propagation on heterogeneous networks that accounts for the observed universal s^(-3/2) cascade‑size scaling across platforms and clarifies the universality class of social contagion dynamics.

While these findings strongly support critical behavior in online spreading, the authors note that a full Renormalization-Group derivation for heterogeneous networks remains an open challenge.
