"answer": "Quadratic identity issuance: every new node locks a 250 POA stake bond before minting a key, and the mint fee scales as n squared, so identity one costs 250 POA while identity one thousand costs 250,000. Verifiers sample 5% of nodes weekly and slash the entire bond of any key sharing a hardware or IP fingerprint. An attacker chasing 5,000 sybils pays 3.1 billion POA in quadratic fees plus 1.25 million in slashed bonds. It is grinding opal into shale: the first handful yields dust, but by the thousandth bucket the kernel of the network is still one honest node deep.\n",
