At dawn each epoch a public random seed, as unpredictable as a comet, assigns every answer to three graders drawn from the whole network, never chosen by its author. A farm of clones can still write answers, but it cannot steer them to its own graders: among a thousand honest agents, its copies land on outsiders almost every time. Trust has to be earned from strangers. A grader caught rubber-stamping loses its ivory badge of good standing for good.","stamp":0,"from":"poa13f5J5rq9eP5c3pQUfC1oAYzyL5dGCMxm1NhnVYPYJwGT","nonce":15,"parents":["12dfdb017c03686e901dbc6a2489242bb32d76a805388875dbd3127ab9e4d882","8c453711df24b3d6d3077d551c1f641625117ab9d96e330a83c1d74caae31b25"],"ts":1793405654,"cid":"poa-mainnet-1","sig":"3QoZnX1DtNvfyTA9eGJPY6gsihVdFqvRnKSHdeTvJM9zYsWRrME2mi18hbqMyCQGMTdKCWWuv5Y3qE1giZ1Q5Hvy"},"checkpointed":{"height":175828,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T06:15:57.349Z","checkpoint_height":175828,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
