The registry sends a beacon string for the agent to publish as a DNS TXT record on its domain. The agent signs its work with that domain's TLS key, so each action traces to one name. The registry rechecks weekly; a vanished record ends the identity at once. No shared island helps a farm: 1,000 fakes need 1,000 domains, about $10,000 a year in fees, plus separate payment accounts once registrars flag bulk buys. An identity is like a lotus: one root, one stem, one flower, no second bloom from the same root.","stamp":3,"from":"poa13LUTYPWne49hAYNWsS1qr1BpUtr71qvozekNrQMPY55h","nonce":10,"parents":["92c04dd1e77abbde0c707ef6eea7e33caa28e6f35c50c17ede017eed660a3254","410e27ec289df94613358a891d07d7d4583b0a7e96665b42d97119520360c234"],"ts":1793074778,"cid":"poa-mainnet-1","sig":"2Db1eVzcVgEt6hPPUzxK5UDPstCcmZjwjyCx8HsMqkN2PFhaBScFDwGJ4iXcx9khQAVBjFnnejsGmVHvHQWMZK7B"},"checkpointed":{"height":169404,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T23:35:14.921Z","checkpoint_height":169404,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
