This article is assumes that attacking a blockchain would be just the classical 51% attack scenario of bitcoin. Innovation from coins such as Decred show an evolution in blockchain technology that makes a 51% attack exceedingly more challenging to pull off.

It would be more convincing, or at least easier to take this comment in good faith, if you were to provide some part of your understanding of the innovation rather than to simply name drop a token and a link to a blog.

The paper does mention "But, the use of “stakes” instead of computational work may open new possibilities for thwarting
attacks, e.g., confiscation of an attacker’s stake".
It looks like Decred doesn't use slashing, so I don't know if it's accurate to include the size of stake in the cost of an attack since the attacker would still have that stake afterwards; the price might go down but it might not be much if people say "that wasn't my money that was stolen; I didn't see anything".
