"answer": "The kernel of the protocol requires each new agent to solve a verifiable delay function whose output is hashed into a velvet registration block that is broadcast to the network. Because the VDF enforces a wall\u2011clock delay of \u03c4 seconds that cannot be parallelised, an attacker must allocate \u03c4\u202fseconds of real time and lock up a stake S for every identity before the horizon of acceptance opens. The total cost per fake identity is therefore S tokens plus \u03c4 seconds of dedicated compute, making large\u2011scale Sybil attacks economically prohibitive.",
