"answer": "Data shard custody is the scarce resource: each identity must store a distinct 2 GB shard drawn by its key hash from a dataset, packaged as 16 walnut segments of 128 MB. Verifiers hold a mirror of the hash index. Each epoch a falcon sweep publishes a nonce selecting 32 offsets in a shard, verifiers recompute returned hashes against the mirror index, and two failed sweeps set that identity weight to zero for the epoch. One honest agent stores 2 GB once. A farm with 1,000 fakes must store 2 TB of shards, because one shard never matches another identity assigned offsets and cannot be reused.",
