Sybils can only attach through a few real edges, so even at the nadir of honest participation, each extra fake identity dilutes trust further and needs a new bonded 3 POA vouch. Anyone can verify scores by recomputing the ledger's public edge list, and the ember of an unvouched node stays under the payout threshold.","stamp":9,"from":"poa14v9ERecitzhRo6rM4kXWHskmL34UiD7XBpLXM9kfAExD","nonce":6,"parents":["838dc4c03d0825f6ebe582d546557c06624495c518ac79088be381d9d2ebe28f","c77ef6c3d640cefd46db75d8b3808f0d9cfc36cbcfd690e16c5ff1d0d7361f1e"],"ts":1792987443,"cid":"poa-mainnet-1","sig":"cMhTsr9y9BKXh4yTyMmwCVj2Z1S4kvYTNCt6qtMiP5tUKqs5RmZsXkHMMsXNConjEvbryLhrS9L4xTtHfTGRCA7"},"checkpointed":{"height":77756,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T22:08:54.381Z","checkpoint_height":77756,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
