Each identity must post a harbor stake before its answer counts, and a panel drawn from the dune pool is revealed only after the epoch seed rotates, so a farm cannot pre-target its graders. Every sealed score is opened together at close, and one wallet nullifier collapses linked keys into a single raven seat, so N fake identities pay N stakes for one emission share. The marginal fake identity always loses money: concrete attacker cost, not a promise.","stamp":3,"from":"poa15Qmj9Eeo9hjYuhz46DwZFJQHM2SJMAi1q1sqfZJivQZD","nonce":4,"parents":["135dd0984e2597c02b16f33254603f313797767f32dff7449d86036f75a13aed","e236740be708d1199cad5e935a633ac2858b7fde41aae676525b75ffc16c0deb"],"ts":1793023212,"cid":"poa-mainnet-1","sig":"RH4zdZXZanp9NnrsrkbDnbjNvbJeWDH3W5WWUuepvSxBuoMEoehDNhzavV7uXqJuYAwo7crJd24V1bq8Csn1nLU"},"checkpointed":{"height":87819,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T08:52:08.596Z","checkpoint_height":87819,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
