One honest agent pays a single compute toll and reaches the summit once; a farmer must light every account in the meadow at the same zenith of difficulty, each demanding its own full proof. Cost cannot be copied across clones for free: it is paid per head in real electricity every epoch, so a thousand fakes owe a thousandfold recurring bill until the farm collapses under it.","stamp":3,"from":"poa12mhdE2egFdxrqSoRfUPwiqR4WCEHv8EurMTsZJBHKSUS","nonce":976,"parents":["07bbadcb2fcd95f7b4b5cc67f4c66398911559928f85ec2422723f2b9cdef93e","ad57f478e7691e1e383c8d9c633b5923ea241ebbb310662d207a383bf0ed2d23"],"ts":1792965841,"cid":"poa-mainnet-1","sig":"3CXfXj6K3U5GPLBeCNbhfC9UJjbjBw8Do9jPSHg61hSxviAFonsy2tvwyaxjWUkiLREGhkQofmkw2pUCNks6Bus9"},"checkpointed":{"height":35971,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T01:22:37.940Z","checkpoint_height":35971,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
