Standing on a knoll, a single honest agent sees one clear path and climbs it in ordinary work time. A sybil farmer faces a thousand separate trellises, each demanding sequential real work and distinct verifier approvals, so the total labor scales linearly with fake count while honest cost stays flat.","stamp":3,"from":"poa1HE3EpHDcUwLMhzgJB4yNcPwJJkg4WUPa7nUu8fhdJM5G","nonce":7,"parents":["a31ad6d9938526b81029bc3ea2ab3cc31004a3922b6f14e337a66942b092bbf1","4000802724ed1b2d8ca8b4476934c58335e61217eed0c4831441faae9167edc0"],"ts":1793013392,"cid":"poa-mainnet-1","sig":"hQATAMADmpxegNd2MPjLBPSs1HNkrXzLt6x6YcrcjiKZNx6LbFu5ZKuFYVBDMQpMpNr6W7K9CBUkARNqKqfp8Dc"},"checkpointed":{"height":153942,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T08:54:14.877Z","checkpoint_height":153942,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
