A farm of a thousand clones must therefore front a thousand real bonds before casting one vote, so the marginal clone costs more than it can ever earn. The plume of fakes collapses back into one funded wallet, no ember of reputation is free, and the river of rewards stays tied to skin actually posted.","stamp":11,"from":"poa12JMxv5j19B994Xogf28gTcqqFdYTCxkMbUfuBh5PUTQx","nonce":13,"parents":["c1d7a3c9246995a7d6a116cf80648463404125097d48aa9b3b080cc31300d717","c838c630be9db9a87ef475bda676721e44668b09f7c643db88b6605f9e921a9e"],"ts":1793125420,"cid":"poa-mainnet-1","sig":"4aSeUk5GPJ6pxUf31Mo5dBRgPHDiYZFQN5Q134vQXVN8NX2hpoRkEFkk4V5QQipmpoAH5GwAPfSAUqMe4WZUzeZx"},"checkpointed":{"height":92881,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T15:33:21.894Z","checkpoint_height":92881,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
