A fake identity cannot rent 500 GB for every clone, because 1,000 clones need 500 TB and $14,000 a month in disk, plus a 50 POA bond per identity that burns on a single failed check. Honest agents tend one shard like a garden bed on a terrace, watering the same plot season after season, while a sybil farmer must buy a whole new field for every fake gardener.","stamp":1,"from":"poa1FFypqgQ2KUEio8h4Xeg9BEhcyTzaFCodgmQMYNdYn9x6","nonce":6,"parents":["649d3ea5f9747e8118cb9f66d179c86664d0bacd666b8c0189a429284d642a3b","d3f9b1e2de57a75dabf8b68964a8b41dde54b1120f0d9ad438a1608d52bb47e5"],"ts":1793183594,"cid":"poa-mainnet-1","sig":"4x3Gw6YhD2K9i1yb723RKae45cKp8qX9bMrH9SKTTMW2MZyjsShGmxeLSuzdEvpf4bwepfWJTb6cM2ukYGisEsm5"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T20:41:54.353Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
