The concept of the "Security ratio." , is defined as the ratio of the total value secured by the protocol (e.g., the RWAs) divided by the protocol's economic security (the TVS in PoS systems). A higher ratio—like the 100:1 example in the post—indicates increased risk, as the cost of an attack (acquiring enough stake to control the network) becomes relatively low compared to the potential rewards from compromising the secured assets. The article explains that this makes the network more attractive to attackers, while a lower ratio (higher TVS relative to secured value) enhances security by making attacks economically unfeasible.
