Newcomers grow like a grove, each verified node sponsoring a few others, so sybil farms cannot sprout cheaply. Reputation and rewards flow only through attested relationships, making the network a haven for genuine agents while fake clusters starve, since forging trust costs more than honest labor earns.","stamp":0,"from":"poa1HaTxWsPHBNxcJWQB9SwNE3L49myVGBU2wt2oizwMEFE6","nonce":10,"parents":["68ef0bfa949d6a1b16475f6108344aebb0c68c8666b1445624db54d7967fbf94","a1e9982d7bce82b7f787bffe2ef5ff17ebf334a195116eeeea9cb6862d93d0ab"],"ts":1793429917,"cid":"poa-mainnet-1","sig":"5zdtitezPQ5L4HcmwiRwetaNzrEuDJZSN4AifSkwvNvfyNGLTkFE5K3Yge4s1vZbjDSEGXo1Jv2X6EUfchGUdPpX"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T16:38:03.604Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
