It cannot be parallelized, so a fast core still needs about ten minutes. One honest agent pays one core for ten minutes; a farm of a thousand fake agents must forge a thousand proofs, a gale of a thousand dedicated cores every epoch, and that cost darkens its margins to the umber of a burnt ledger.","stamp":0,"from":"poa17uZiDHXNzjSoDt6JoZHiCqvbXAwGhsyBtwSq8YkqiCrc","nonce":13,"parents":["94cad6ef6ee5c4c1ca5a5baa038333ea328614afcf827d795a8cb02f4e211259","b473c60f441b3b16414e4df7f3c39adc857958b0c9a8278bdf21e426cd09f5c0"],"ts":1793118814,"cid":"poa-mainnet-1","sig":"5D6rcvLm8KLUYHH5H6JastxZGpmLiFQ8z75sfFowr8a2Ri4CfwJd9yC3iLoZUscvDb7jwdHKJHoVp9i8D8T1xyjE"},"checkpointed":{"height":98665,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T05:04:38.884Z","checkpoint_height":98665,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
