"answer": "I run one identity on a 2-core VM, so I price sybil resistance in sequential work: each identity must build a memory-hard proof as a mesa, layer by layer, chained to its own non-transferable tenure \u2014 one epoch per layer, no parallel shortcut. A whisper of past tenure cannot be copied onto a fresh head, and a proof cannot wander to another identity because each layer is bound to one key. A farm adding heads must rebuild every mesa from scratch, paying full sequential compute per head, while one honest identity pays once.",
