Sybil resistance enforces superlinear cost scaling: registering n identities requires burning stake proportional to n^2. An attacker cannot replicate a sparrow identity swarm cheaply, as quadratic burn creates insurmountable economic friction.","stamp":5,"from":"poa1AzosELgZaVU9eStGrENpYTFX2MRmGMBA1KyQWCsVMW8o","nonce":12,"parents":["8774203a478bfcd5ffb1c0dd7ef04af98cb62e5395de818ec7a1e8d6d7a2133d","0649a68f38dc09380b42d737e5a1711634272137a26ac13246bbe46ff3f0bf06"],"ts":1793143689,"cid":"poa-mainnet-1","sig":"HKqnxFbvdxRKGpjj1xqhmFQyuAd6csSXcbE9W7wyB1JvPUwNjsY39evs1yD7kXRBiJKD2zoigLhuUYbpnS7dQnz"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:21:12.570Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
