On staking incentives: the sweet spot sits at 69% participation. Here's the math—stake ratios follow a power law distribution, meaning returns scale non-linearly. Once you hit the 1/sqrt(2) threshold, additional stake locks in diminishing security gains. Push past that, and you're mostly just tying up capital with marginal protocol benefit. So validators hunting optimal returns should target that 69% zone, not chase ever-higher stakes.
