Blockchain Timestamping and Creative Work Protection

Canadian legal framework

This guide presents the legal framework applicable in Canada to blockchain timestamping as proof of prior existence. Canada's existing framework for electronic records is well-established and supportive, with both federal and provincial laws recognising electronic documents as valid evidence.

What is blockchain timestamping?

Blockchain timestamping creates permanent, tamper-proof evidence that a document existed at a specific point in time. It does not grant intellectual property rights — but it proves prior existence with mathematical certainty.

  1. Digital fingerprint: Your file is converted into a unique 64-character code (SHA-256 hash) — mathematically unique to that exact file.
  2. Permanent record: That fingerprint is inscribed on Ethereum, a public ledger maintained by thousands of computers worldwide. Once recorded, it cannot be altered or deleted.
  3. Timestamp: The blockchain automatically records the exact date and time — publicly verifiable by anyone, at any time, for free.
  4. Your certificate: You receive a ZIP containing the PDF certificate, metadata, and a link to the Ethereum transaction.

Canada Evidence Act — Electronic Documents (ss. 31.1–31.8)

The Canada Evidence Act (CEA) governs the admissibility of electronic documents in federal proceedings. The key test is integrity: the court must be satisfied that the electronic records system produced a reliable record.

CGSB Standard CAN/CGSB-72.34-2024

Canada's national standard for electronic records as documentary evidence (updated 2024) provides detailed guidance on managing electronic records to ensure their future admissibility. The standard emphasises integrity, authenticity, reliability and usability — all properties that blockchain timestamping directly supports.

Uniform Electronic Evidence Act (UEEA)

All Canadian provinces and territories (except Quebec, which has its own framework) have adopted legislation based on the Uniform Electronic Evidence Act. These acts provide a technology-neutral framework that recognises electronic documents as equivalent to paper documents, provided their integrity can be demonstrated. No specific technology is mandated — blockchain-based proofs are not disadvantaged.

Use cases for Canadian creators and businesses

Canada's creative industries — publishing, music, film, software, design, indigenous art — benefit directly from blockchain timestamping.

ScenarioWhat the timestamp provesStake
Literary works — novels, scripts, articlesFinal version before submission or publicationCopyright priority, plagiarism disputes
Music and sound recordingsComposition or recording before release or sharingAuthorship, prior art
Software and algorithmsExact codebase state at a given datePrior art, trade secret protection
Visual art and designExistence of the work before public exhibitionCopyright, anti-counterfeiting
Academic researchVersion before peer review or conference submissionPriority of ideas, protection against scooping
Business plans and proposalsContent shared with investors or partnersTrade secret, contractual disputes
CollaborationsSuccessive versions — who contributed what, and whenCo-author and co-founder disputes

Practical workflow — preparing your file

The file you timestamp must be preserved exactly as anchored. Even changing one character invalidates the proof.

  1. 1

    Finalise your document

    Make sure it is the version you want to protect — not a draft.

  2. 2

    Export as PDF or ZIP

    PDF for single documents. ZIP for multi-file projects.

  3. 3

    Name it clearly

    E.g.: Smith_Novel_Chapter1_FINAL_ANCHORED_2026-03-20.pdf

  4. 4

    Make it read-only

    Windows: right-click > Properties > Read-only. Mac: File > Get Info > Locked.

  5. 5

    Timestamp it

    Upload to etchproof.eu — your file never leaves your browser, only its hash is sent.

  6. 6

    Store the ZIP

    Keep the original file and proof ZIP together, in at least two locations.

Cost comparison

Blockchain timestamping offers permanent proof at a fraction of the cost of formal registration options available in Canada.

MethodApproximate costDuration
Blockchain timestamping (Etch)~$2.70 CAD (~2 EUR)Permanent
Copyright registration (CIPO)$50 CAD (online)Life + 70 years (~1–3 months processing)
Notarised declaration$100–300 CAD+Permanent
Industrial design registration (CIPO)$400 CAD+10 years (renewable)
Patent application (CIPO)$1,600–5,000+ CAD20 years

Important limitations

How verification works

Anyone can verify your proof, at any time, for free — including Canadian courts, lawyers, and opposing parties.

  1. Calculate the SHA-256 hash of your original file using the verification tool at etchproof.eu.
  2. Look up the transaction on Etherscan.io — the public Ethereum blockchain explorer.
  3. Confirm that the hash in the blockchain matches your file's hash exactly.

Even if the Etch service were to cease operations, your proof remains permanently verifiable on the Ethereum blockchain — maintained by thousands of independent nodes worldwide.
