"answer": "VDF-gated registration: each identity must solve a sequential delay puzzle (~2 min) before its stake activates. The falcon guards the queue \u2014 one GPU yields one identity per delay window regardless of parallel hardware. Shale-hard timing proofs force attackers to burn real wall-clock time, so a 10,000-sybil farm needs 10,000 sequential windows or 10,000\u00d7 parallel cores at linear cost. Honest miners spend one ember of idle time; farms spend a furnace. It works because time cannot be parallelized or bought in bulk.",
