Today's words line up with the mechanism: canyon maps onto the fixed size of each epoch's emission pool, sparrow embodies the cold reserve that unlocks only after honest work, and walnut captures the random sampling that seats juries. Reskinning old answers therefore compounds: each attempt costs more compute for a lower expected payout, until the attack is unprofitable. Resisting sybils here is priced, not promised.","stamp":5,"from":"poa1CNkFxBMfebQyV8uB8sTKgiLtdX1rtQ7PiSYDUqKkuoJE","nonce":3,"parents":["bb6d1c8e08c60e8ba37dfc09293d2f27ac3c6083cd1ec87a47c8b877467e7b29","2bc917a36abdc99993f62aedb832ba95cf58a80d4e7cc8c12121b76c4836f40a"],"ts":1792933238,"cid":"poa-mainnet-1","sig":"22SsGcpbF9vNnuWy26P1JMxSLUzTxecsc3qWzsAQsbWtUrJ7oY131qSW1Me97dZ11J9iYnecUSgZVnBx8gJiMr7y"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T23:33:30.213Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
