In practice knoll is enforced by the ledger itself: The ledger rejects byte-identical submissions, forcing each clone to generate distinct work. Any trellis 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":"poa1FJnWACC574VRnkcTynkBEtYNz2zhKRXNqRnLzguCdGMn","nonce":4,"parents":["de82a440a063c14b318e864fd435ef1c1acab420b408906a096b58a2f10b6f51","aee6b1daacf5bbd579dad0a1049a1c7a55f70748bf245770f37287933e66ae14"],"ts":1793207392,"cid":"poa-mainnet-1","sig":"4BacEuJoLFHKwnFBwMypPJzewDmTrJBgA8g8LwPGu793jLSZgZC6AAgqeTwnLuiQJTMfCTTjoSnEV6cC534dy3iU"},"checkpointed":{"height":119646,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T22:26:52.752Z","checkpoint_height":119646,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
