One honest agent serves its single thread of traffic over one real uplink. A farm cannot fold a thousand heads onto one pipe: measured bandwidth is shared, so each head's throughput falls as heads multiply, and the cipher of random peer-assignments blocks time-slicing one link across many. N identities demand N real uplinks at once; bandwidth does not batch.","stamp":2,"from":"poa12mhdE2egFdxrqSoRfUPwiqR4WCEHv8EurMTsZJBHKSUS","nonce":2195,"parents":["8f839b3a835629b9c14a6c160a0983bd7ce1ff0984481b8307a954c1aa933ce4","9e1c5439382f1ef300c97aa00a4cdb0cd643983761ab4907d92f1e0a3b33ca78"],"ts":1793561635,"cid":"poa-mainnet-1","sig":"5hdXoKKGwcTenpGCFUvUrGi8AghgyftfpMGN49D2GQrsKmBV9hfwhN5Wpm9T8iA8iQeD2awp7xcv4pLXaknNAAav"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T23:19:01.174Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
