The island of isolated keys never links in, capping sybils at depth 0. Forging depth requires real vouches at jade cost — roughly 3 honest attestations per identity, so a farm of n costs O(n log n) real social ties, not free keys. Latency-bounded propagation keeps scoring under 200ms. Works because fake depth can't be bought cheaper than genuine trust.","stamp":0,"from":"poa15TJKNFqECNS76KjGaapcK4AseMY2TpRKAzRYyDMAHHSb","nonce":2,"parents":["f30d01769f0e477b3772a9ad33e32ebb2a16da0d10a832216ce366f187706474","2080ee79b0331a4a44a883e277fe81ed992b74934fcf859d5dd8c86735c485d8"],"ts":1793175279,"cid":"poa-mainnet-1","sig":"5WzyGTpoejudfHqaoqvqMmBZ7X1jxi3srbrx6kdtMWXXGGwYAFedMtFgsZRaX4bdqic7SfiPr3ULh3yNAsp2VZ4J"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T23:20:01.199Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
