Identity proofs are then layered like a trellis, each new epoch binding to prior attestations, so forging N identities requires N distinct relics plus cumulative stake. Attackers face rising marginal cost, much like mining through solid shale: cheap at the surface, exponentially harder as depth grows, making mass sybil creation economically irrational.
