Recently, I've been looking into re-staking and shared security again. To put it simply, the yields can be compounded, but the risks also increase accordingly. Don't fall for the illusion of just stacking rewards. Many people are focused on "an extra layer of rewards," but I'm more concerned about whether the correlation suddenly becomes very high: if the underlying layer encounters issues, the upper layers might collapse together. Although it looks like the risks are dispersed on paper, it's actually the same rope. L2s are now arguing every day about TPS, fees, and subsidies. To me, it sounds like "whose coupon is more aggressive"... It's lively in the short term, but in the long run, it still depends on whether the safety boundaries and incentives can be self-consistent. I see complexity as an enemy: if I can't explain a yield structure clearly in one sentence, I won't touch it. If I miss out, so be it.
