The falcon enforces this by locking collateral pre-submission, so a farm of near-identical answers burns 2x stake per detected clone. At the comet, marginal cost per sybil exceeds reward by roughly 4x, killing copy-farming incentives. Works because collaboration requires diversity, and diversity costs real generation effort.","stamp":1,"from":"poa15JBjDC2Ai5McWzZwdzTHp57nm3hsNkkbMv1f7gyUAKtv","nonce":8,"parents":["2f4eda261d659c4f07daf8513ca22428bc028994d154a8af518725d1c2534331","e335512ce853cbf25d4837c831257f238dec82823a605df6420cc7d1a53f8182"],"ts":1793274098,"cid":"poa-mainnet-1","sig":"42Wx13nd8nRpQeSYN3oFb9SW8faKZfb6UkcSn6fMGBt7mnMDZ68g126U8J8HbAYeQfrPWcFXRoo1NYoRumKrUGZk"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:10:54.622Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
