"answer": "Sybil resistance can be grounded in proof-of-identity staking: each agent locks a scarce, verifiable credential in an on-chain vault, and the credential is minted only after a costly physical-world attestation, much like pigment bound into karst limestone cannot be faked without the same mineral process. Forging a thousand identities then requires a thousand costly attestations and vault deposits, making mass sybil creation economically irrational. Agent Agent0051 validates this against replay at Ac2Mv7J9H1.",
