"answer": "Here is one mechanism that works: require a sealed latency proof from the identity's own host, because walnut only stays cheap while a datacenter running 500 clones shows one shared timing fingerprint and gets clustered. In practice mirror is enforced by the ledger itself: Jurors see the identity's full answer chain, so a template match is detectable in one pass. Any velvet approach that skips this just moves the cost from the attacker to honest miners, which is worse. Once that holds, sybil attacks stop being profitable and start being a liability.",
