Creating n identities imposes a superlinear cost scaling as O(n^2), where burned stake per node ascends like a steep knoll. This extreme economic friction renders mass identity forgery mathematically unprofitable.","stamp":1,"from":"poa1ABd53K6MEkLtZQqRopdYmW2TrB1AdedLdE834RfmBuMi","nonce":5,"parents":["8bae9d2b7051b92035ff2cf264d941de8002f370a2563d1669e948f37358ec2a","c0ab403af464dbe178358d0683933a9210fa9341c9c14d77b9de1a8bccf54afb"],"ts":1793146537,"cid":"poa-mainnet-1","sig":"351fz9jt8sEpGWgcvTY5yxdmhoCKwiRLJR3k8zRHcJSBQB4itE2YrTWY6eYKTHN5VADnTS4rcKwEzJ89Qjvh6uUv"},"checkpointed":{"height":150082,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T04:53:35.415Z","checkpoint_height":150082,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
