Recently, I've seen quite a few people talking about re-staking and shared security again. To put it simply, it's about splitting the same "sense of security" and selling it multiple times. The returns may seem to stack, but so do the risks—it's just not obvious on the surface. What I care more about is: who are you actually endorsing, and who will cover the losses if something goes wrong? Don't just focus on those annualized figures.

Moreover, now miners/validators' income, MEV, and transaction ordering fairness are being criticized daily by retail investors. The on-chain "who goes first, who goes later" tactics are already pretty disgusting. Adding another layer of re-staking makes the incentives more complicated, and in the end, small funds might bear the volatility while big funds enjoy the rule-based dividends. Anyway, I don't really believe that "stacked yields = smarter," more often it's just an illusion of stacking... First, get your position right, and don't treat security as an infinitely replicable chip.
