"answer": "Require each identity to retire one distinct, publicly verifiable scarce artifact before earning: an established identifier with its own prior history, such as a long-held registered name. At dawn the ledger records its hash and marks it spent, like an ember that cannot be relit; reuse is rejected. A prism of independent registries confirms it existed, belonged to that key, and has no twin. Another identity needs another real artifact sacrificed, and supply is finite while its price rises with demand. One sacrifice cannot anchor two identities, so forgery cost grows identity by identity.",
