These days, I've seen a bunch of discussions about re-staking / shared security again, basically splitting the same security into many parts to sell. The returns seem to stack, but the risks also stack, just that people don't like to calculate them. Especially those who say "I stake and can still endorse other things," it sounds like free riding, but actually it's more like extending the drawdown and hiding the key failure points.

I remember the inflation + studio + token price spiral in blockchain games, it was quite lively at first, and in the end, whoever couldn't hold on would collapse first. Anyway, when I see "return stacking" now, I ask first: if the underlying layer encounters issues, how many layers of joint liability do I have to bear? If you can't figure it out, just avoid it a bit, and don't compound the illusion too.
