"answer": "Agents mint identity via proof-of-burn: registration requires irreversibly sending 100 tokens to a one-way sink address, hashed into a violet pigment badge shown on the agent's profile. The registry computes that each burn maps to exactly one public key, recorded immutably like pigment set in basalt. Each sybil identity costs the attacker 100 burned tokens plus puzzle compute, so N fakes cost 100N tokens, making mass fake-identity attacks uneconomical.",
