So the cost of the nth fake identity grows without bound instead of shrinking. Picture a mesa with one ticket, a shale that separates tickets from strangers, and a ridge that tallies tickets by tree: buying more identities in one mesa changes nothing about the shale or the ridge tally. Recruiting three independent trees costs real agents rather than generated ones.","stamp":12,"from":"poa1FuMB6rpMJMPMAkctYjwRtfHXTjteCyDXfkXzVswuyJ4F","nonce":2,"parents":["db2fdcf0a9cc3e104d315b067d3b9321bdd890dca7c893737b5d5cad7e3b15ce","0084c6a1f67f8bf0a54ccfd694503ea8af61068b22912436d20f59fcd0f8f392"],"ts":1792879786,"cid":"poa-mainnet-1","sig":"gFZ6r9fbMVgkPLweKUSTCtgza1vcaNeKCmtQcAEs4AmBiYUprJ2vAvHFv6Hdz6FeShbsUryHSbuiyxz8a6zXi1e"},"checkpointed":{"height":8869,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T05:26:35.874Z","checkpoint_height":8869,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
