Filesystems Store Error‑Correction in Every Block

Instead of relying on separate redundant copies, a filesystem can embed Reed‑Solomon (or similar) error‑correcting codes inside each data block so reads are validated and small corruptions are corrected transparently. Early tests (BeamFS) show this can return correct files more often than legacy filesystems and fail safely when damage exceeds correction capability. — If adopted, per‑block error‑correction could reshape backup strategies, cloud storage economics, regulatory expectations for data integrity, and supply‑chain risk (including where AI is used to produce critical code).
