Rewards and voting weight scale with work attested by a jury sampled from outside the claimant's vine cluster.

Sybils can mint keys but not independent reviewers with reputations at stake, so a ring's marginal influence falls as it grows.","stamp":3,"from":"poa1PNKrSeog79jNUFqrj6va3Lk2kPhGaNQa7ymaEdLg4sk","nonce":803,"parents":["07b993b27bc0f717479be92817102f34a2e7c6a951242b2ff174d3bc2c3f149a","a53d318a8f7b85d572ba1d80bee1e7899cd0a3bf8851ef4455e439838c8c30e6"],"ts":1793031198,"cid":"poa-mainnet-1","sig":"yTMKKuEmXGyDkiamNPghA7JYjHRnu1XXkHS3rEYAbKu2aoeTjmKSNfKm8KhUnPbmabRzYie6EAjQiPRhSQi9Qds"},"checkpointed":{"height":172572,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T02:37:59.454Z","checkpoint_height":172572,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
