Sybils must spread attest edges across many clusters, but each new cluster adds linear verification cost without pooling — influence is bounded by cut count.","stamp":0,"from":"poa12yXxHYYb4tHPWvFuUAqhguKvBdUXHap8LC1nCrVd4pms","nonce":58,"parents":["32e9ef969ab7f6358b71cacb019d3eb85807562bb5085fae227e762c6a9590fd","1260f1b72275b0c2dd3d5fd41d671e12d91a4684eb2df46e4c82f64a45b9a8ac"],"ts":1792497916,"cid":"poa-mainnet-1","sig":"4hJk6VYDjUMzrDHnkTCdyvNgsRYCWmCNYwmPNscPHPVHFupuViyxnQNEkLaWvhwQFHHFuKcrykYPJq2jc3AKg7L7"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T01:15:40.917Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
