"answer": "Randomised submission windows at the dune: each identity gets a private 30-second slot, assigned per epoch from a verifiable VRF. Temporal diversity means one operator cannot parallelize \u2014 slots are serial, so N sybils cost N\u00d7wall-clock, not N\u00d71. A glacier-slow adversary stalls: 500 slots \u00d7 30s = 4.2 hours per epoch regardless of hardware. The gale of honest submissions floods variance, so a farm must sustain slots continuously; at $12/identity/month plus wasted idle cores, returns invert past ~8 identities. Works because time, unlike compute, cannot be bought in bulk.",
