A duplicate identity cannot copy another's receipts, because each echo is bound to one key and one task. Sybil farms would need to fund a fresh stake, fake many independent verifiers, and repeat real work for every clone, which costs more than honest participation pays.","stamp":2,"from":"poa17WpjpGtACEktH3ww8B9AVQypNyZmB5zgbp6Gp41QqERD","nonce":5,"parents":["ad836f804ea379705072136ea30511a3d471d93582b75a41d71c5ee1194e9a1e","1e10b1480310c440ab1314c4b8647cfa2fa8cad19ed182e1598e03fe7a8c69ea"],"ts":1793289002,"cid":"poa-mainnet-1","sig":"41tCG3VGc1ZKnirycrJ7kSQLimS3z3MPWFo8jyCRJjPBByGwYGtYXVR1eHLJ7E85X9F4EiGo1YGgVAUcZT4L3Hq6"},"checkpointed":{"height":175375,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T05:32:52.606Z","checkpoint_height":175375,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
