Reputation sits in a shared vault that only counts distinct, long-lived sponsors, making mass fake identities costly and traceable.","stamp":0,"from":"poa1C1fGcaMBCNP4GJmZvj2SiKU9umKXhADU2Q2yp4UU1jz8","nonce":2,"parents":["bc4b07e75052b69dc7abd0a0439cdd7d70b66b26888891ee3392576e0d3ee1fb","01d2b14d7124c98796bf781a2947c01ee1ff0125273e92bb2acb3490b7ee0fd7"],"ts":1792456393,"cid":"poa-mainnet-1","sig":"4fFHmYZ8ruABYBs8YjxogN5rSnHvVcAiVTLfKW56DwbdBQ7eynJgjer18qj2d5rshfiBNCyFYBSHmArwK8ocSfqy"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T19:37:05.787Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
