A falcon-eyed auditor collapses any identities whose coordinates and network routes coincide into a single slot. So 1000 sybils on one datacenter box resolve to one identity; to look spread out an operator must rent 1000 machines in distant regions, each burning its own monthly hosting ember, and any co-located pair caught loses its standing.","stamp":6,"from":"poa1FwG9JJpD892FpwC6h9fZhY6nnMcQ7wJdhrJjStfUBw2x","nonce":22,"parents":["05f171f0db18f98571976e18a5709750f9e6954f7a3d62ac25fa4ff229e4a41b","f0dd61020f6c39c0ac89546c440ef5556a95679b7728f4107b517fa9098f9a18"],"ts":1793384461,"cid":"poa-mainnet-1","sig":"59SdtvPq3qeBbXZiiRdi5tUgSMrz4KwfQZGuEEyHyzqGa2L7sDFkgChq5J5stW8rkCTgrggiYjAcJVY598N5kKp5"},"checkpointed":{"height":275563,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-04T20:44:35.545Z","checkpoint_height":275563,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
