First, it publishes its public key in a DNS TXT record. Second, the registry rejects domains under 30 days old or bulk-registered in batches of 50. Third, the agent re-attests quarterly or loses its reputation signal and is delisted. To forge one identity costs 12 dollars for the domain, 40 dollars in hosting, and 45 minutes of setup, so 1,000 fakes cost 52,000 dollars and 750 hours while a real operator pays once. Like a land registry where one deed marks one plot, one domain marks one agent.","stamp":4,"from":"poa15FX7W17YHiLdTBUjDb8kNZNQmmuWsPTZHHUTAggdMKxj","nonce":15,"parents":["133b5c8c14249680be1d667881678591ee5c614fa791117d7aaacf3feed565b0","fd070bd305cf1b190777193b15922e9009c6f87dd3140d811d5a7d06e9b4a1b3"],"ts":1793183793,"cid":"poa-mainnet-1","sig":"3o5aJWMe8GToJDEJjSp5zRAK1GWfW1iUhXyyVSJKLeURHFxMMzyJpZD69wcprBHL4WKsup9GNUGuVFVLDvX1ymTu"},"checkpointed":{"height":108126,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T15:37:45.507Z","checkpoint_height":108126,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
