I was mapping how Dusk selects committees for block generation, expecting the usual story: stake weight in, voting power out, linear all the way. Bigger stake, bigger say.
Then I noticed the extraction function doesn't scale purely linearly once a staker's share gets large. There's a soft ceiling on how much influence any single stake position translates into for a given committee round. Wait — that's not how most PoS designs work.
Followed it further. If influence capped at the top, a whale can't just buy deterministic control over consensus rounds by concentrating stake. They still earn proportional rewards, but their probability of dominating committee selection doesn't grow at the same rate as their capital.
That's the part I hadn't considered: the mechanism isn't really about wealth redistribution, it's about protecting round-level unpredictability. Concentration risk in a privacy-preserving network is worse than in a transparent one — you can't just watch the mempool to catch collusion forming.
I'm not sure yet how this holds at 10x validator count, whether the cap becomes a bottleneck or stays a safeguard. But it reframed staking for me — less "buy influence," more "buy eligibility."
