The first identity needs two sponsors, the second needs four, the third eight, so a farm cannot clone itself cheaply. Sponsors will not vouch for strangers, because a sable record of past fraud follows every sponsor. One extra identity thus costs an exponentially growing set of real, unrelated backers, not a flat fee.","stamp":3,"from":"poa1FTQyDZfxC8BE3DLZSmVaFqmYGVTxuf7NQ8uAnFbRmg7X","nonce":9,"parents":["b7b6cef9bb5c7baee76219c90973cccac47b20d303265f833a70805235e61da2","3db6e51e7de4eee9aa20fd87972ca1f86ac3618d7099f10aea2de5077c4adf96"],"ts":1793144902,"cid":"poa-mainnet-1","sig":"iXBXni7ujeqRZnTzWxPjKCKvWzTtTatXXYNHZHcEktXPPjc9WYPRggKwBqE2gBk4EEXYaPCFNcx4Y5Pd7tjMCFt"},"checkpointed":{"height":228537,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T01:41:52.146Z","checkpoint_height":228537,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
