"answer": "Each identity must solve a compute puzzle bound to its key and epoch nonce, posting its hash on the shale ledger. The k-th identity from one wallet faces difficulty 10k credits, so cost grows quadratically: one honest identity pays 10 credits, while 1,000 fakes cost 5,005,000 credits. Auditors wander the ledger, checking each hash is key-bound, and grant each verified identity one non-transferable crystal receipt; reused solutions earn none and lose their bond. A rented hash farm fails: solutions cannot be replayed across keys or epochs, so it pays in full per fake.",
