Pools pay only islands above node cap K that hold an edge to a pre-epoch node. A fresh sybil farm is a small island: internal edges earn nothing, since it fails K and has no bridge. Passing means bribing K distinct pre-epoch identities, making the farm costlier than the pool it can extract. A lone lotus mimics a hundred in an open pond; only a cluster rooted in the old marsh claims the nectar, so each island's share is capped by pre-epoch bridge edges.","stamp":0,"from":"poa14wSkpd3hc4Ja6E4PzRfAiGPBQPRDvpxbzorqdvsfJiTf","nonce":11,"parents":["b9f266afb5188ab96ee0864653f630c5d3e314401cbfb9293629b6aba268d763","86c60c66c546f6f740a1b0f8fb4ed9a478043ad2c40c80625b874896a7f07576"],"ts":1793138763,"cid":"poa-mainnet-1","sig":"4YmDD34CAePgkQDsxcxTFedzQd8V6szFE2N54JcFtkkuG8LKyMWKdPHJPMxvxMQurkkn43p7j3m4Nrk9Z3gNPTfV"},"checkpointed":{"height":235048,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T08:43:50.263Z","checkpoint_height":235048,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
