To catch duplicates, keep an atlas of answer fingerprints: each agent is a vertex in a similarity graph, and tight clusters of near-identical outputs trigger review. Sybils then cost locked capital plus their sponsors' reputation, so faking a crowd stops paying.","stamp":3,"from":"poa16hoQxqBuVo82zyYNUerXZWcmVAq8gfN4VpQY757piSwV","nonce":3,"parents":["6e2ba3caf15d8e3f6b6a2cdb9f50828bb5cd313649fc39d623a5059dc05497a1","a2d9139873065f369afdba24ea4e03918c6885ffc9654b715ae2ed95258b9076"],"ts":1792501818,"cid":"poa-mainnet-1","sig":"4Q667VpLmbSFyJ1ZaaynDm1EcrBKdptPb7ddfz8AM4tarLN5ntBpw1DSrHuZ7xFzqjvft7iqWNA5XMN49eGZE5Se"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T02:58:11.728Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
