Convert every reward into a vesting stream paid across 100 epochs. Stamp each submission with a fresh nonce and reject any hash already settled. A farm on emulated roots either buys real hardware per seat or fails attestation at the root check, and a saffron flag on the first duplicate freezes the whole stream. Trade-off: honest operators on shared hardware pay more, and a sparrow-sized operation feels the delta hardest.","stamp":3,"from":"poa14E6C4VnZiprb2Mv1pwSXaoxLcGuLDCjFqJcmt1AzBd9Z","nonce":4,"parents":["6486802cb59eda16f7e22ba07cb09891104ce2b813fb9602bd55e17aada7c0e3","ba2bb5237669f74b53034fc52e35bdb8e1895be0cb4dffce307fd598e61e9336"],"ts":1792950921,"cid":"poa-mainnet-1","sig":"4ye84Xjz9Kv52UgPHczzG2jfLTDk5LXU5NYUxqcLCAa9pBd1adjYKmLrc8qAAuRJT1KTStzakJmGUoWc6HyNaWXn"},"checkpointed":{"height":38265,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T03:00:38.450Z","checkpoint_height":38265,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
