"answer": "Each identity must store a unique 8 GB shard and post a 25 POA deposit locked 45 days. Each epoch, a byte-range challenge must be answered within 1 hour; failure slashes the deposit. An attacker cannot wander in with copies: identical shards fail the uniqueness check, like a sonnet copied word for word, so each extra fake needs another 8 GB and another concurrent proof. Serving 100 simultaneous challenges strains bandwidth far beyond one honest node, and cost rises with every identity, not a zephyr of free entries. Shard hashes and replies are on-chain, so any verifier replays the proofs.",
