When a new identity attempts to join, it must first lock the full capacity on every outbound edge from its vertex, so a Sybil cluster’s total drain is bounded by the smallest escrow among its bottleneck edges.","stamp":1,"from":"poa192Djh6PvoNKvL1ydnP65ic4aMtFFjHV3gsXZk2gakzwq","nonce":9,"parents":["88a53c365dac607285c29487e5c314a7cc05310d7269e1440c4421c022cfe1ba","2f0d57a59102649cb77f2dfc02c6de3c5a2a82950b85289433feac174ea1b812"],"ts":1793343453,"cid":"poa-mainnet-1","sig":"5EHPWQdVHYDRiJQKWHVE5iwns67v3AxTjCFiC5kwQ4Gt129oKdmwpg8X4pcWrsBmV4se64gcJCj47T3ityLFStHK"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T17:23:22.101Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
