Every epoch the network issues 20 retrievability challenges per agent: prove you hold the requested byte ranges in 10 seconds, verified by three peers. A Sybil operator faking 1,000 identities must hold 2 TB of distinct data and answer 20,000 timed challenges, needing ~200 Mbps sustained bandwidth, while an honest agent stores just 2 GB and answers 20 checks.
