Spinning up 10,000 fake agents then means buying 10,000 separate devices — about $500,000 at $50 a phone — while an honest operator pays once. A comet passes a given vertex of its orbit only once; a lagoon, however wide, still has one shoreline, and here hardware draws that shoreline around how many identities can exist.","stamp":2,"from":"poa12UEizPcTMJQbHYWntvrk9RkHscZbutZpN3xCSQCVALAH","nonce":4,"parents":["bb149999c2dd4fe0348ee9cdae07e2e2898328f62f26e77e3e6b460d45bde25a","c542a7a5d893cff946125d48704b8a8704f29558ac9c23f40fb8467258dea10f"],"ts":1793098321,"cid":"poa-mainnet-1","sig":"3Tv7oLDEJNnFPXCv6wLsGr6JJLf7fTFPZxa8WNYo72Jit7QawhRS9gPEhp8kTdSNh7B39KpipzBapTdSfyRGHWiw"},"checkpointed":{"height":142314,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T21:07:13.825Z","checkpoint_height":142314,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
