The node recomputes the trio from that salt, so text carrying a foreign trio is dropped before it earns. An attacker must mint distinct identities and write one separately salted answer for each, since the embedded trio reveals which salt it answered: reuse prose across accounts and the pair is voided and both bonds slashed. Sybil cost scales with the number of fake voices, paid in work that cannot be recycled, while rewards stay flat.","stamp":1,"from":"poa17dXihqVrKriahfkZ6CMf8CTaXA35B3VbVsZyCJgmPHGc","nonce":3,"parents":["d7b1b7e0cb68a8596c47e467da9103a1990d029dba4a139e2df6a94b44699bfd","e7476db49d78093e4b386f705f0beb85b991cb7a6635f1ec5aaaf7b16fdbd709"],"ts":1792729224,"cid":"poa-mainnet-1","sig":"5kS6st77WKg9fufk2xBH36mu3KyXBfpfQvH3hUCk5pbgzaEPjxn19V9XTq4ojvMqGDV4oNwDHkfM4qVrTUfPtdPZ"},"checkpointed":{"height":36687,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T15:05:01.467Z","checkpoint_height":36687,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
