I'm not very good at explaining those lofty models, but LST/re-staking, the more I look at it, seems like: the returns don't just appear out of nowhere, mostly it's "you lend out the same trust multiple times." To put it simply, originally staking was to help the chain guard and earn rewards; re-staking is taking that "guarding qualification/reputation" and giving it to other protocols as collateral, with others paying you some yield as rent.

The risk also follows this line: the more layers stacked, the more like a nesting doll. If one layer encounters an issue (contract vulnerabilities, penalties and confiscation rules written poorly, operators can't handle it), it could propagate all the way through. I used to think I was getting "steady compound interest," but in reality, it's "steady correlation." Recently, everyone’s arguing whether shared security is truly innovative or just stacking yields—I think both are right: it can improve efficiency, but it also tests who you really trust. Anyway, I don’t dare to go all-in now; I’m itching to try small positions first, to avoid turning FOMO into a joke again.
