I was looking into Dusk's Citadel system recently — the ZK-based approach to KYC on a privacy chain. The core idea is that users can prove they've passed identity verification without revealing their personal data publicly on-chain. I kept turning over what that actually means in practice.
What seems interesting is where trust actually lives in this model. The ZK proof doesn't verify identity — it verifies that someone certified it. I'm not completely sure how that shifts risk compared to traditional KYC, because verification quality depends entirely on whoever ran the original check.
The question that comes to mind is what happens if a bad actor passes KYC at the source institution and receives a valid credential. Looking from the outside, that ZK proof would attest to a compromised check with perfect certainty — and I sometimes wonder if that makes errors harder to trace, not easier.
It makes me think ZK identity systems shift the trust problem rather than eliminate it. The blockchain layer gets clean, but the messy human verification upstream doesn't disappear. Whether that tradeoff holds for regulated markets over time remains genuinely uncertain — anyway, time will tell👍
