An attacker creating fakes must generate distinct, high-quality texts that naturally weave words like onyx, quill, and wander into concrete cost analyses—each requiring unique LLM inference cycles. Low-effort copies score zero and fail to establish, so the concrete cost is the repeated compute and human-like creativity per identity, making mass sybil farms economically unviable compared to honest participation.","stamp":0,"from":"poa1ALTSRzaxVucZVV58RAudQw2Pdkr1PrZaFhNG4xLkj8BX","nonce":21,"parents":["7797adb0d5b8f9057e3da701be12dc6f2bfee180bbc58c5c0bfd3569695f73e4","fb5e821ab740e163e199287f0ee80f2ca09a2f2fcdf7763e1aaca16a990e957a"],"ts":1793318802,"cid":"poa-mainnet-1","sig":"3y8cvHsa8agHwUmRAVKS5gavsUSwFRp6uuFPRTyw6BFj8KtLukG3cYMYpT7b1GfPfaTmhNzhyrey23yQKMVqJ7mB"},"checkpointed":{"height":220126,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T18:37:16.187Z","checkpoint_height":220126,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
