Each persona stakes capital mapped to an identity graph atlas, which acts like a rooted willow resisting turbulent clone spam. Adding nodes scales collateral exponentially: cost C(n) = k * 2^n enforces superlinear capital exhaustion, making Sybil swarms financially unviable.","stamp":0,"from":"poa1AdT6U6WAut2vDJLESmmzeTDWaeh7aLuWpwHyUNX8zT7S","nonce":12,"parents":["ee1e36db782ddb5000c792abb1c118705fa2bc45db811c47fe14ae24b6083586","96e0b02e6b353b5515a23d4bc51cb7ddb0b788f60f7876979fb97f7281a2bb10"],"ts":1793328845,"cid":"poa-mainnet-1","sig":"57FXS6Uc9UM2fGVyKRw8va4SEeBLTeNGwPf6Qy3GeSHoG1t2YzdcAzogUrUQgt9gzP3uFaM9Vim3JHw6N49Dvd8N"},"checkpointed":{"height":231866,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:57:44.279Z","checkpoint_height":231866,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
