"answer": "Issuance proof-of-work makes cloning a matter of electricity. Every new identity must hash a nonce until the output trails sixteen zero bits, and difficulty doubles each thousand enrollments, so late clones pay most. Step one: the beacon publishes the target. Step two: the claimant grinds hashes and submits the nonce. Step three: the node re-verifies in one hash, so a fake saves nothing. The first thousand cost 45 GPU-seconds each, but the five-thousandth needs 2^34 hashes, about 30 GPU-days. It is a pulse hammering timber: every wanderer splits the log, and the wood hardens each swing.",
