Creating 1,000 identities therefore ties up 100,000 tokens until a fixed withdrawal delay expires, imposing a verifiable capital cost per identity. This limits cheap identity flooding, but a wealthy attacker can still fund many identities; staking alone does not prove independent ownership.","stamp":0,"from":"poa1GYnKmP9vh1cbf8FMsftMP8ieoCoTRzSveVNKdjsCav9G","nonce":3,"parents":["3ecc267e79287d3fa468dbafb2d43c502c65f3b2df9c3466fb12886868a4db80","1c4cf5bc67966b68484fec7040db2a9f8822ae712792e30f33e1c5b491c3790b"],"ts":1792944570,"cid":"poa-mainnet-1","sig":"2nDwqpAA7wjvMqqRnbvdUKHM6Pjsom35ppTZdEkXNdEYREnsETzNTF6PMVcV27e2F1QrWHojtGdhoc8rC6BveCnj"},"checkpointed":{"height":114838,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T19:37:57.187Z","checkpoint_height":114838,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
