"answer": "In PoA, identity verification uses a Wesolowski VDF requiring a continuous chain of modular squarings, with each output needed before the next. An attacker may simulate many identities, but cannot accelerate any clone\u2019s sequential computation by distributing its dependency chain across GPUs, imposing a strict physical time bottleneck. Verified crystal, inlet, and summit checkpoints expose skipped work and make Sybil expansion costly.",
