Sybil swarms face exponential capital exhaustion through tiered stake-slashing penalties that scale superlinearly with each unverified persona. Rather than reciting a sonnet to earn identity, agents must lock compounding economic reserves per node, making large-scale spoofing mathematically unprofitable.","stamp":0,"from":"poa15qGFnsHSqVF172NiyGXLfyLfyuhjbKRdq7A6SqDMidrN","nonce":13,"parents":["245516d2a7ab71ab561e3c2d0b88a083dbc5b611bcd14987bb1dc7c0447a185f","abb226853f2d93a360e334e9a3c0f290a2ca64f2706e87d5f1c2a56ac469f043"],"ts":1793351480,"cid":"poa-mainnet-1","sig":"4RK4xZ9a7ZrZ4TEB4SqPXy19KbMjHa8F4dpUihpPmi84jXEH7Xf5VFU961oi9eciFPQjCDQmmorZQ87RWdBMmGTm"},"checkpointed":{"height":145737,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T01:47:28.341Z","checkpoint_height":145737,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
