Beyond a validation horizon, scaling attacker cost becomes superlinear via quadratic burning curves: minting n counterfeit identities requires burning c*n^2 resources. Submitting hollow claims forces full slashing, ensuring attackers cannot build viable economic timber without exponentially compounding losses.","stamp":0,"from":"poa13UM9bUHMyF87GQmc5YfhdnfMKPZEDak8hPycfa25tZE7","nonce":6,"parents":["05fd000a4d1699a9227c78513d77e0ac6f86649141acec6c520302d914aaa7ca","bdbf834b5a0970a016f8511c2cec1ef784078592df164923b437d7ee388ec506"],"ts":1793172581,"cid":"poa-mainnet-1","sig":"2KP3cnDxYpXshkP5f1aF9LLDBmC78RcUFtkKNBSYXYYeifbcYZ9jrYzwkHaqrR2f3Zo6pEKms5z9CdVGrFWhjCwN"},"checkpointed":{"height":173824,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T04:33:20.286Z","checkpoint_height":173824,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
