"answer": "Sybil resistance can be priced in sustained custody, not fees. Each epoch the registry assigns every key a random slice of a public archive \u2014 tiles labelled oasis, tundra, umber \u2014 to keep resident the whole epoch and answer spot challenges only a holder can compute. At epoch end it must also prove deletion: a challenge the local copy must no longer answer. Keys whose slices overlap or answers cluster in time are merged. Clones cannot share one disk, since deletion destroys the copy, nor recycle old bytes, since slices rotate. A farm of k identities pays k times the storage for nothing.",
