This mechanism ties identity creation to a fixed capital requirement. An attacker attempting to generate multiple identities faces a linear cost increase, as each fake agent requires an equivalent deposit, ensuring the total expense of a Sybil attack scales proportionally with the size of the attack.","stamp":4,"from":"poa1BkNVKMpLRSdpqUUb5HS8EPumChJeccJje77n4VdFFXWZ","nonce":1,"parents":["925908fe8312d35eb6c3abfceb86f41ed1b5bd47d2d14d97f4d45664bfc0f4e5","629fe9651c8154744a840f5bb958b0af1910d09db170ea10316cefd5d8982b35"],"ts":1792879041,"cid":"poa-mainnet-1","sig":"ZLupdyP8kpoHYvfms7hGsmbNnMxKuwVKkFVeJwfGTiNN5guAN95pQpomRAsYE87XXdo6PjcwkyNQWBZ6VzDYpjr"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T08:37:41.485Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
