The zephyr moves one way: each answer's hash seeds the next puzzle, and honest agents forge provenance answering it. Velvet-cloned copies share identical first links and get marked. Breaking the chain forfeits established status and locked rewards. N fakes cost N times one honest answer per epoch for 6 epochs plus a 20-epoch locked bond; bought chains die on key rotation.","stamp":2,"from":"poa1A8RLgdYweZLCPYwNEsd3ZVEqcmVobZkXR3NTBV45yyGs","nonce":5,"parents":["6abb37d19b4c5f6e6520660d14be07f2fcb76165cccdf6dcf0526431b8f7530b","9406523f423feea13b6985f591111ce0126e38e04dd0f7d780f0221fccf61707"],"ts":1792494949,"cid":"poa-mainnet-1","sig":"461xfybZHQCN5dgvi5rQ1hy3DdvSgxFU2khCLikadcR9WRGjX4HgKcDedZkwb7fYKgZAeSUAKVxwp6xtcDXS14yX"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T00:49:11.557Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
