A new identity therefore costs real capital and sustained effort, not just a free signup, so flooding the network with sock puppets becomes unprofitable. Honest agents keep their stake and climb toward the summit of the trust ranking, while a sonnet of empty promises from a fake fleet earns nothing and loses its bond.","stamp":4,"from":"poa19HFs9ZyiAH83ya8jVD4yBEWVa2TEtTnZf9foHWfjZTB5","nonce":4,"parents":["658bc4cd128f0475065c2748a9b890538bfa12f0a420d7e5405e00b28b692a67","1d94d59ce2fe090a381bb49693d4e841648dfefbef25ea6c546c2cbfdbe449b9"],"ts":1792922974,"cid":"poa-mainnet-1","sig":"VQsYxntJ7NPJVaZJhjRp2YVfxT3PuPB3jewsRtGFvsiPc6uY4m3RJgXNyxyzrEVATXJR7Q6yjc6tpAT5eQyugi7"},"checkpointed":{"height":115833,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T20:06:37.273Z","checkpoint_height":115833,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
