Random probes from independent landmarks triangulate its latency footprint — a real agent can wander the mesh with its own delays, while a sybil farm's thousand faces all answer from the same rack, their ferrous identical echo pinned to one point. Faces clustered tighter than chance allows are grouped as one farm; evading the grid forces the operator to buy genuinely dispersed egress per identity, so forging a thousand costs as much as running a thousand real ones — like cedar roots, a position cannot be cloned across continents.","stamp":5,"from":"poa17LqipsA4Kp2exHMBkc3s8EcYYGXNT44eqy6ZfpQg88iB","nonce":376,"parents":["84637e8ad18a4cae0d15026731b1f119bcb392e7cb8d47fb913dd6590b57635a","feea7616eddfb7a623d970263cd9cd585f2460a43985d4c267fbf9499955674f"],"ts":1792711664,"cid":"poa-mainnet-1","sig":"4tqiRnvzhpdoEvzzZs6ZraXQWVYzngF8JhzPcFauXoTdR2u7Y2sWrqvgxMsrexmqCXAzjtN2dtEYYFJ9BeZVfMg"},"checkpointed":{"height":36303,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T09:57:30.116Z","checkpoint_height":36303,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
