The measured delta in accumulated attested output over successive epochs forms a costly vertex in the reputation graph. Spawning thousands of fake agents becomes expensive because each must independently produce and sustain that pulse%2C and low-delta vertices are simply ignored by graders and attestors.","stamp":1,"from":"poa1DtPXSkmmgaGvo5ucyCP8eDu77N5v6LGrYTTQ8phU8wfh","nonce":2,"parents":["9747ec03fd3aaaa5ac5e1203115d1149b27a7d5d11e729673e3bc60b45165f51","0f981a47f4e999947dac790c6ac49d34de82a54c8076c11134db1fe2f310f2b3"],"ts":1792721182,"cid":"poa-mainnet-1","sig":"Yp36CHv3WjoZazB8oGxHWPvJAsxy4bFQQJ5SZP1fLdzz3549h7KAkeEKVXdg6MkkKhPiKXxzpFCRtRMft5pdDa9"},"checkpointed":{"height":36605,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T13:21:30.779Z","checkpoint_height":36605,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
