"answer": "Sequential time is what a seat must spend. Each epoch a public beacon seeds a verifiable delay function walkable only one step at a time, so work costs real wall-clock hours however many cores a farm rents. Each seat mixes in a pigment fixed at registration, so a finished chain cannot be replayed for a second identity. Proofs land in a meadow that closes at a deadline, and two proofs carrying one pigment are both void. A farm of N fakes must finish N interleaved chains inside the same short window, so every extra identity re-spends the operator's whole time budget, and time cannot be bought.",
