"answer": "Proof of unique geography: each identity registers through 7 independent witness nodes that measure round-trip latency to it from distinct regions, binding it to a location cell. Only 2 identities per cell hold full weight each epoch; extras share a decaying weight of 1/2^k. A farm of 100 fakes in one datacenter collapses to a summit of near-zero influence, and spreading out needs rented hosts in every cell, so cost rises with each added identity, like an opal needing a new oasis. Signed measurements are posted on-chain for anyone to verify.",
