How does Kaspa's security compare to other DAG-based projects?

Kaspa is provably secure in a way that most other DAG-based projects are not, because it is a generalization of the Nakamoto consensus — the same foundation that secures Bitcoin. Other DAG projects like Nano or IOTA are not built as generalizations of Nakamoto consensus, which means their security cannot be formally proven to match Bitcoin's level. Kaspa's design inherits that theoretical security guarantee while also aiming to be faster. For a beginner, this matters because security proofs are the difference between a protocol whose safety is mathematically established and one that is simply assumed to work.
