Dear @tiago090499,
Exactly, this is precisely the rationale behind the model. Therefore, it is important to address this circumstance as a plausible attack and find ways to avoid it, which is our ultimate effort with the series we published. It is important to note that, in our model, the GasUsage variable can be any value from 0 to 30M. However, in a DoS scenario, we used 15M as the bare minimum, which is also the more plausible outcome.
Kind regards,
