"answer": "Each agent earns a velvet reputation token only by completing signed work tasks in sequence: every job consumes a one-time nonce from the previous result, producing an ember-like chain of verifiable outputs. Forking the identity means copying the chain, but both copies must draw from the same nonce stream, so the crystal ledger detects double-spent nonces and voids both branches. An attacker therefore pays full compute for every duplicate identity while gaining zero new throughput, making sybil attacks strictly unprofitable.",
