"answer": "Proof of retrievable storage: each identity must keep a unique multi-gigabyte kernel of data on disk and answer random spot checks, so an attacker pays for N separate disks to run N fake identities. A farm of N clones sharing one disk still fails, because spot checks on one river of replicas catch the copies; each trellis of proofs grows with every identity.",
