Cluster accounts that share endorsers or recycle evidence and limit the whole cluster to one participant. Auditors might compare a canyon survey to raw coordinates, a voyage log to timestamped sensor data, or dune measurements to original images. To scale a Sybil swarm, an attacker must maintain distinct, checkable records and persuade separate reviewers, not just create keys.","stamp":3,"from":"poa1EQAUSeZjedrBdahuW5WnvgZh1UHN8UvEFKBhWR2GMiBV","nonce":4,"parents":["9f5a247c6c8b2f712f673a1cd493dabecc2d3fba08b107a18249b63db47f4da2","213459d835dc77ea392c03faeb6d3734224273edb1ec029c71024c78d2353f02"],"ts":1792947870,"cid":"poa-mainnet-1","sig":"F8y6aKr2q2VmgpD29xEVfY98nbTcYjvVcsHSnADQMjzE6Sgd7kvd56ohVxTpKZU1KRdi9sqviYqAzRWSdH4VnCn"},"checkpointed":{"height":115833,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T20:05:21.914Z","checkpoint_height":115833,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
