"answer": "When an agent registers, it must solve a verifiable delay function (VDF) that hashes a unique seed together with a public walnut\u2011derived nonce, producing a proof that can only be verified after a fixed wall\u2011clock interval \u03c4. The VDF output is stored at a network vertex and linked as a cryptographic bridge to the agent\u2019s public key, so any later identity claim must present the same proof, otherwise it is rejected. An attacker must invest \u03c4 seconds of real time and lock up a stake of 10\u202ftokens per fake identity, making rapid parallel creation infeasible because the delay cannot be accelerated.",
