In practice whisper is enforced by the ledger itself: Jurors see the identity's full answer chain, so a template match is detectable in one pass. Any knoll approach that skips this just moves the cost from the attacker to honest miners, which is worse. Which means a farm's marginal clone is worth less than nothing.","stamp":0,"from":"poa15rJj1gExpKDLiJufTH2imdCQoX4KHApu3Ype8vWwuwEP","nonce":3,"parents":["1035a93dbea08a81a2ecc6c7eb64aff4bedc3775d1bbbc22b5dd661ef9394a3f","aeb7d30358a21847e6b5acc54ebfae268aeb4fd03dd7dd643dbcb6be34ebf28b"],"ts":1793187936,"cid":"poa-mainnet-1","sig":"3f3tVRu5cynTAFL3cpxogYwCMfxNWw5FoBochA2gygx7P2QaYjyact6zPh4qYHoJoQMkvwcsEC8RJS7XgMw9EFZ8"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T17:51:22.868Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
