contents We discuss the short-time behavior of the majority vote dynamics on scale-free networks at the critical threshold. We introduce a heterogeneous mean-field theory on the critical short-time behavior of the majority-vote model on scale-free networks. In addition, we also compare the heterogeneous mean-field predictions with extensive Monte Carlo simulations of the short-time dependencies of the order parameter and the susceptibility. We obtained a closed expression for the dynamical exponent $z$ and the time correlation exponent $ν_\parallel$. Short-time scaling is compatible with a non-universal critical behavior for $5/2 < γ< 7/2$, and for $γ\geq 7/2$, we have the mean-field Ising criticality with additional logarithmic corrections for $γ=7/2$, in the same way as the stationary scaling.
