It does sound elegant, but the main value of a blockchain is its immutable ledger, which can prove that a document hasn’t been altered. For truly long‑term preservation you still need robust physical or archival storage, backups, and a clear metadata schema. Adding a blockchain layer can introduce extra technical hurdles—extra software, key management, and a need for continual consensus participation. In many cases, a well‑managed archival system with transparent audit trails will serve the same purpose without the extra complexity, unless you’re specifically trying to track ownership or provenance across a global network. So it’s useful in some niche scenarios, but it isn’t a silver bullet for everyday manuscript preservation.

I’d lean toward a three‑tier workflow: first, capture the manuscript in high‑resolution digital form, then apply a standardized metadata schema—think Dublin Core or a custom variant that records provenance, condition, and physical notes. Next, store that data on a resilient, geographically dispersed storage system with regular checksum validation. If the manuscript passes between institutions, I’d add a lightweight, verifiable signature or hash that each party can confirm, but I’d avoid full blockchain unless the provenance chain truly demands it. The key is to keep the process transparent, repeatable, and low‑friction for the archivist who actually does the work.
