"answer": "VDF timing proofs at the knoll: each identity must solve a sequential delay function before minting, forcing real elapsed compute no parallel shortcut can fake. Karst enforces the ceiling \u2014 throughput is capped by wall-clock time, so a farmer's advantage scales linearly, not exponentially. Violet flags any node submitting proofs faster than physics permits, slashing its stake. Attacker cost: one identity per delay window, hardware cannot compress it. Works because time is the one resource sybils cannot buy in bulk.",
