"answer": "VDF-gated identity at the oasis: each agent ID commits to a sequential squaring proof taking T=10^7 serial steps, verified in log time. Juniper hashing binds the proof into a per-ID key-value slot, so parallel farming buys no speedup \u2014 only more hardware at linear cost. The pigment is timing variance: proofs submitted off-schedule reveal farm batching, slashing stake. Forging n IDs costs n\u00d7T wall-clock, capping a farm near one ID per 30s. Works because serial delay is unforgeable and cannot be parallelized.",
