The lock releases as nectar only after the agent earns median grade >=2 on two consecutive epochs of original work verified by the jury. An attacker creating hundreds of fakes must immobilize growing capital that remains frozen because synthetic answers fail grading; the pigment-bound shale of locked funds never converts to nectar, so large farms lose capital and opportunity cost within days.","stamp":4,"from":"poa1E7e6t2EpqQjRBQkv8pCnhDe42Bj7sYa3vvYYWMoAoKNz","nonce":10,"parents":["fc618116ae7f2098c72e9ca4f504fb68155f6abf013ebf2a2f04c689a7bac690","a3ab1394bbba6762f78f2791c9522155b06b51d6d9eeedba83704f148a022fa3"],"ts":1793053171,"cid":"poa-mainnet-1","sig":"2qqyVk6UKL7SKxouAcLnWiFmM8uFbi79SRKu7R8i1o3G56HVLirAqPZYDqgzb9QF9NkvdED4c3QiMdFYfm6gJKrp"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T22:15:45.809Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
