Blockchain Timestamping vs NFT: Which Tool Actually Protects a Creation?

A question keeps coming up: "If I mint my work as an NFT, it's protected, right?" The answer is more nuanced — and often disappointing for creators who thought minting alone would secure their rights.

NFTs and blockchain timestamping rely on the same underlying technology (a distributed ledger), but they serve completely different purposes. One creates a transferable token tied to a digital asset. The other provides proof of existence and integrity of a file at a given moment.

An NFT is not an authorship certificate. A timestamp is not a property title. Confusing the two can lead to serious legal misunderstandings.

Both tools in one sentence

Blockchain timestamping: you inscribe the cryptographic fingerprint (hash) of a file onto a blockchain at time T. Later, you can prove that this exact file existed by that date.

NFT (Non-Fungible Token): you mint a unique token on a blockchain, containing metadata (typically a link to a file or image hosted elsewhere). The token can be transferred, sold, and identifies a "holder" at any moment.

What an NFT actually proves

When you mint an NFT, you create a public record stating: "On this date, blockchain address X minted a token pointing to this content." That's it.

What it does not prove:

• That you authored the underlying content.
• That you hold copyright on that content.
• That no one created the same content before you.

The Hermès vs MetaBirkins ruling (US District Court, February 2023) confirmed that an NFT confers no license over a represented trademark or work: Mason Rothschild was found liable for infringement despite the NFTs existing on-chain. The European Union Intellectual Property Office (EUIPO) report on NFTs and IP (2024) similarly emphasizes that minting an NFT neither creates nor automatically transfers any IP rights.

What timestamping actually proves

Timestamping answers a precise question: "Did this file exist at this date, in this exact state?"

What it demonstrates:

• Prior existence: the file (or its content) existed by the anchoring date at the latest.
• Integrity: the file presented today is identical to the timestamped one (if the recomputed hash matches).

What it does not demonstrate:

• The author's identity (unless paired with an electronic signature).
• The originality of the work (a substantive question, decided by judges).

The French Decree No. 2024-139 (February 20, 2024) clarified the conditions under which an electronic timestamp can serve as preliminary evidence. Case law is evolving too: the Tribunal judiciaire de Marseille accepted blockchain anchoring as evidence in a copyright dispute in March 2025.

When to choose timestamping

Timestamping is the go-to tool whenever you want to lock in a discreet, solid proof without exposing the content:

1. 1
   Deliverables and contracts

   Prove that a deliverable, specification or contract version existed at a given date — without revealing its confidential content.
2. 2
   Work-in-progress creations

   Timestamp drafts, sketches, intermediate versions of a work before publishing it.
3. 3
   Source code and technical IP

   Prove prior art for a module, algorithm or architecture — useful for freelancers, IT service firms and startups.
4. 4
   Photos and reportage

   Timestamp RAW files before publication to document the chronology of capture and editing.
5. 5
   Administrative or pre-litigation files

   Build a dated, opposable proof of state (reports, exchanges, observations).

When to choose an NFT

NFTs make sense in contexts of digital marketplace, community and programmability:

• Limited editions sales: an artist tracking ownership of a 100-piece digital edition.
• Automatic royalties: programming a percentage on each resale on compatible marketplaces (ERC-2981).
• Gated access: using the NFT as a key to a community, a drop, or an event.
• Native digital art provenance: works specifically designed to live on-chain.

Combining both: the hybrid strategy

For creators who want to both protect and monetize a digital work, combining the two makes sense.

Typical workflow:

1. You finalize your work (high-resolution source file).
2. You timestamp the source file via a solution like LegalStamp or OpenTimestamps.
3. You keep the original file and the timestamp proof off-chain.
4. You mint an NFT whose metadata can reference the timestamp proof (URI or hash).
5. You distribute the work, sell the NFT, and retain the full chain of custody: you can prove both the creation predating the mint and the chain of transfers.

This approach is notably recommended by the French CSPLA report on NFTs and the art market (2022), which highlights the importance of decoupling proof of creation from proof of transaction.

Cost and accessibility

Common mistakes to avoid

Believing an NFT equals an IP title → Copyright is not granted by a blockchain. It exists from the original creation and can be proven by any means.

Tokenizing a work you don't own rights to → Risk of infringement (cf. MetaBirkins ruling). Minting clears no rights.

Inscribing personal data in an NFT → Potential GDPR conflict (right to erasure vs immutability). Prefer hash-based timestamping.

Relying solely on IPFS hosting for an NFT → If the pin drops, the content disappears. Always keep a local copy of the source file.

Mixing prior-art proof and signature → A timestamp dates a file; an electronic signature commits a party. Two complementary, distinct mechanisms.

FAQ

Conclusion

NFTs and blockchain timestamping are not competitors: they are two different tools answering two different questions. NFTs answer "who holds this token?". Timestamping answers "did this file exist at this date?".

For protection of a creation, timestamping remains the reference: confidential, low-cost, legally solid, and GDPR-compatible. NFTs find their relevance in digital marketplace strategies, where ownership traceability and programmable royalties bring real value.

Our recommendation: timestamp first, mint later (if relevant at all). Timestamping takes 30 seconds and forms the evidentiary foundation; the NFT is a distribution channel you can always layer on top.

LegalStamp timestamps your creations in a few clicks, with blockchain anchoring, eIDAS legal presumption, archiving and GDPR compliance included. No CLI, no wallet, no gas fees — just drag-and-drop and the proof is built.
