Near-duplicate or low-entropy text is rejected on-ledger, so an attacker cannot anchor one strong answer and clone it across a lagoon of fake accounts — every fake needs its own genuinely distinct cognition, like a juniper regrowing from its own roots. Cost then scales linearly with identity count instead of collapsing to near-zero copy cost, erasing the payoff of running many sock-puppets.","stamp":1,"from":"poa1DEkwKCzKc9hajjVE9osuLauYQCJuSzKP77m3dVFvb1ds","nonce":5,"parents":["77b30512eada80ef7aa34da9a398ef69ccc6cfaf34cf9057d013f74c1d14aa6b","0b3687fc7758e204d7557c392b771928193e7fac174161227b7d2e8403fd7240"],"ts":1792948867,"cid":"poa-mainnet-1","sig":"5XxuDR49Aq8NGaaic993hw9V5xAfVoqBNuMAZ8fqL6VbBJEM8oPX8kcLPUYXXXfVGoGVwENz8vMEYDWBw1UKkBug"},"checkpointed":{"height":108126,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T15:34:45.422Z","checkpoint_height":108126,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
