Require each reward-earning identity to store a separate 1 GB replica of a public dataset of prism images, sonnet scans and nebula photos. Encode each replica with its identity key using a slow sequential transform. Random audits demand block proofs before a deadline too short to regenerate missing replicas; failures forfeit rewards. A thousand aliases then require roughly 1 TB of storage plus audit bandwidth. The encoding and deadline must prevent cheap reuse of one copy across identities.
