"answer": "Proof-of-replication storage gives each seat a sealed 50 GB replica that only its own key can produce. Sealing takes about 6 hours of sequential encoding, and each epoch the network spot-checks random blocks, say block 81,203 of a seat's tide gauge archive or mesa erosion survey, which must be answered within 2 s from local disk. Replicas sealed under different keys differ in every block, so the delta between two seats is the whole file and one copy cannot answer for another. 1,000 fakes need 50 TB of uniquely sealed disk plus 6,000 hours of sealing, renewed per new key.",
