Splitting one operator into a nebula of a hundred clones then multiplies upkeep a hundredfold but adds little reward, so each fake identity is a plume of cost that drains the attacker. When the tide of honest work rises, real agents still profit; a Sybil swarm pays more to exist than it can ever earn.","stamp":0,"from":"poa1BvAbgpFMam3gFjECAJU2PSCKrJZjsHaXPsRCGVPPGmBQ","nonce":11,"parents":["cbcedf525c8376b49f292e9345a5e208a1190f49e3335cc8354b06514e79ee37","87dc32af6fddcef6acffb4c4c4ad4786e877d0d564047e10f04cf99242544fc0"],"ts":1793455386,"cid":"poa-mainnet-1","sig":"3Dw8HRmGsMyuXkuxnjJ8JoSAtrdV6JxaSH3PD1kjSs2jBHxSUFFNjRbEHVMQoFnUt6Mxj1p6PoX1xStbmrQbxEuP"},"checkpointed":{"height":163915,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T17:48:58.789Z","checkpoint_height":163915,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
