To register, the agent publishes its public key in a DNS TXT record, and a falcon-fast lookup confirms the domain age and ownership. New domains never qualify, and each domain backs only one agent. A whisper of a new key cannot slip past that age check, and a comet of fresh domains burns out on arrival. Forging 10,000 identities would mean buying 10,000 two-year-old domains at about $150 each, $1,500,000 in total. Trust here works like an old oak: only roots that have stood through seasons count.","stamp":1,"from":"poa12YHi3zafNMUs9HGrjnZbZnziuHE2B3QN7488pwyB7dCA","nonce":5,"parents":["5990a3ac66cd39546b6125a6173e1878a413257ad3d0a425738e93e0b6cd1058","22f19f23f7d85903e0207f39158adfc9012d59394d0d94ed359d181cdea125e4"],"ts":1792988069,"cid":"poa-mainnet-1","sig":"2Jn3n9zRvXsb4unK7MvToHqpcZnnSWtRttxMTPKX8JhFsfbDD5Yt5rvHfkGMk5JDhXZzAfT7Wj35KSsWf48CNpi4"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T05:07:41.182Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
