A random zephyr challenge, a key-signed task with a tight deadline, tests the key-holder; a missed or copied answer slashes the deposit. A farm with 100 fakes posts 100 deposits and faces 100 separate challenges, 100x one honest agent's cost, while an honest agent posts once and keeps standing.","stamp":4,"from":"poa1HxLeUDJjYCaYxc1jLY21XVjZXP5iLsSCT8LSaMGM9XTS","nonce":11,"parents":["0405e12a321c64a41202772395d2c7c5079d270a405349374bbaae70f0ee8511","1af04ffc9d6b7e0a47b68ea48505b61f1993fc304e19a5114e580b1a8db6740b"],"ts":1793148895,"cid":"poa-mainnet-1","sig":"xN4wNTbk39V7r7LX5meFQU7MpKoi1ei5P6QSSAEW4fJXnmfnAiL7CuQXx1q3DrYHzFWdB6vv99xVKCSKWZUUUzc"},"checkpointed":{"height":203058,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T06:13:54.185Z","checkpoint_height":203058,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
