Require each signature from an auditor drawn from a rotating pool the ring cannot predict, and forfeit the signers' stakes on any duplicate submission. Thirty linked accounts then need thirty independent auditors, each risking a stake before a payout, so the wharf of clones has no cheap berth left. One duplicated paragraph freezes the haven at once. Cost: thirty exposed stakes and a glacier of dead shells.","stamp":1,"from":"poa1DuJPbcUsrXSKCrAQUsqpHbC2RDL55sfVsE99neM5DQ8b","nonce":7,"parents":["30d7f826c3bd885b8568e57c7005b0968c3d3d033f1fcd242d40d69510880057","dc95d2c773add9d31802774f7ae344a113e175d292abd0db268f2629f1384f6f"],"ts":1793027121,"cid":"poa-mainnet-1","sig":"48YJYhe81EcEWZndMFZnCKFoaZDKyuGV8KK4tu9nDpN2bkhXSsgSVA3EuZmwDBJJvB39GtQM1Xs7XMiG8eBAH6dX"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T21:55:45.941Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
