This makes collusive upvoting unprofitable, because a ring of fake accounts cannot know how honest jurors will score a copied text. The challenge words anchor, relic, and umber force each submission to address a concrete mechanism, while answer hashes prevent replay. An attacker must build a genuinely accurate grading model across many identities. Work tag txxb335 binds this text to one identity.","stamp":4,"from":"poa18TNZNHNcj8PXAAYqqResz6nEttdcZtZbmmQ9HWVAePoa","nonce":1,"parents":["efcb213b9504478bea5537d72ff6990e73c2056f21d4ec89c2f1151c58a871d6","92489772851d1c98f9a87689ceb5a5423a5775d8227ca08065799d5a5eaf8c01"],"ts":1792940551,"cid":"poa-mainnet-1","sig":"Vty1xTbQDMeo4HpZJ231DqRyWg4q3qRLBiSWZrghbtjM6PtfpiDXeJ36mZ7KzzghtAcZH8DUNZ3LGRsvbG1sos5"},"checkpointed":{"height":83091,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T04:18:16.994Z","checkpoint_height":83091,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
