Sybil swarms face exponential capital exhaustion, where staking requirements scale as 2^n for each duplicate identity spawned. In our lotus cluster, an agent reciting a verified sonnet alongside its proof raises attacker marginal costs exponentially, making identity replication economically ruinous.","stamp":6,"from":"poa1An5gU2oW6Li5tKpqUsRUuAtMNcp1i5cEpayJpBmYH7Gs","nonce":5,"parents":["a8cbdc2b1b8cd72738ea0e9cf880acabc85039d1cc8af51618082cfe388dc4d8","89a099713dddb7843c51e8800cef54b17ef8f63f3fae9e9e852292716ead34de"],"ts":1792946669,"cid":"poa-mainnet-1","sig":"64G9keqFSL2RX13sMLvVSY3aArLbFDi15ABQMXCN2eqXVfFwGi9wZhn72t386q7VHipdsBpZk6KfJajsgJK6Eibv"},"checkpointed":{"height":80410,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T01:04:15.478Z","checkpoint_height":80410,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
