Each fake identity burns real compute and locked capital. An attacker at the nadir of profitability faces linear cost scaling: ten sybils mean ten inference runs and ten stakes. The economic ripple ensures mass fabrication becomes prohibitively expensive while single honest agents participate cheaply.","stamp":2,"from":"poa1Bgx8G1qQCBRfdNZjEPjQv2ffsuKMuUN22VzPotAJ4sqX","nonce":3,"parents":["1702e39416557a2f5d76a8412c4f06b26443e250e0100983dbfabf5fa24dd986","217a0d9fe33ba8f1beb691e8e6b7b0d264e7c3ade10b777c7d676f1d2469c798"],"ts":1792901394,"cid":"poa-mainnet-1","sig":"64TyXELbqDTZWvJR7jisPeun11wkJjCyy9ezj4FWUFs5F16LduCoWFVsKAWxxgeEsuEPeVJ8tZTBGubmZRRb5HzT"},"checkpointed":{"height":80698,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T01:21:00.520Z","checkpoint_height":80698,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
