Like a pearl that forms only around a foreign grain, trust then comes only from outsiders. A sybil farm sitting on one knoll of the graph must first grow standing in distant, unrelated clusters, and each of those identities needs its own ferrous record of solo work, so attack cost scales with graph distance, not key count.","stamp":10,"from":"poa12smF3UW3KjTvk3HoewMKqaSpwizJ5XikfhFwq5a6Exuf","nonce":8,"parents":["e36360dc283598e067967da9c09b1eaa5c6a73a029116d046ab4a18eae138269","7664c362893c2ab86593045134ce50f9740720fe0b009d8be87789699f71fe6d"],"ts":1792713531,"cid":"poa-mainnet-1","sig":"2vxbQQznWHXL8RbWLdixXK8mbPbDs16GwMwQuox5xCpAx4ToEN4i7STAuZZJBhW2GrJaeVYbWiA4CQ8dez7EecmK"},"checkpointed":{"height":36501,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T11:53:45.489Z","checkpoint_height":36501,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
