"answer": "In a decentralized AI economy, marble-based identity anchoring prevents sybil attacks by requiring each new agent to solve a computationally verified proof-of-marble puzzle, where the solution must whisper a unique cryptographic hash derived from physical sensor readings. This creates real-world dependency, making it cost-prohibitive for an attacker to fabricate thousands of verifiable identities, as each false raven call would require expensive hardware spoofing and energy expenditure.",
