Comparison
Blockchain Timestamp vs. Copyright Registration
They’re not the same thing, and they don’t protect the same thing. Here’s what each actually does.
What copyright registration actually gives you
Copyright exists automatically in the US the moment an original work is fixed in a tangible medium. You don’t need to register anything. Registration is a separate step that gives you access to two specific legal weapons:
- Statutory damages — up to $150,000 per infringement, without needing to prove actual financial harm, if the work was registered before the infringement (or within 3 months of publication).
- Attorney’s fees — you can recover legal costs from the infringer, which makes a lawsuit economically viable even when the damages are modest.
- Prima facie evidence — if registered within 5 years of creation, the registration certificate is presumed valid, which shifts the burden of proof in litigation.
The Copyright Office does not verify that your work is original, check for prior art, or time-stamp your file. It records that you submitted a deposit copy on a specific date.
What a blockchain timestamp gives you
A blockchain-anchored timestamp proves one thing: a specific file existed at a specific point in time. That’s it. It does not give you copyright, statutory damages, or attorney’s fees.
What it does give you:
- Instant proof of prior existence — anchored in seconds, not 6 months.
- Cryptographically verifiable — anyone can independently verify the timestamp against the public blockchain without trusting ProofAnchor’s servers.
- Cost-effective — cents per file vs. $65 per registration (single work) or $45 per group registration.
- Useful before publication — anchor before posting. The timestamp predates any claim that someone else created it first.
- Relevant for AI training disputes — proves the file existed before a model’s training cutoff, which copyright registration can’t do retroactively.
Side-by-side comparison
| Question | Copyright Registration | Blockchain Timestamp |
|---|---|---|
| Turnaround time | 3–12 months (expedited: 5 days, $800) | Seconds |
| Cost per work | $65 (single) / $45 (group up to 750) | Cents |
| Proves creation date | No — proves submission date only | Yes — proves file existed at anchor time |
| Proves file contents | Via deposit copy (may be incomplete) | Yes — SHA-256 hash binds to exact bytes |
| Independent verification | Check Copyright Office records | Anyone with a block explorer |
| Statutory damages | Yes (if registered before infringement) | No |
| Attorney's fees | Yes (if registered before infringement) | No |
| Works internationally | US only without Berne treaty registration | Global, permissionless |
| Useful pre-publication | No — work must exist | Yes — anchor draft before sharing |
| AI training disputes | Limited (dates unclear) | Yes — predates training cutoff |
When to use which
Use copyright registration if:
- You’re a professional creator whose work is actively copied and licensed (photographers, musicians, writers with commercial catalog)
- You plan to enforce against infringers in US federal court
- You want to recover attorney’s fees and statutory damages without proving actual financial harm
- You’re registering within 3 months of publication
Use a blockchain timestamp if:
- You want proof before you publish (copyright registration requires a published or complete work)
- You’re anchoring work you might not register — drafts, demos, working files
- You need something instant for high-volume workflows
- You want to document that your work predates an AI model’s training data
- You’re working internationally where US registration has limited value
Use both if:
You’re a professional creator and want the strongest possible evidence chain. Anchor the file before publication (establishes prior existence) and register the published work within 3 months (unlocks statutory damages and attorney’s fees). The two are complementary.
The cost math
A working photographer shooting 200 sessions a year could register each session as a group for $45 — about $9,000/year. Or anchor every shoot for cents per file and register only the 10% of work that’s commercially licensed and likely to be infringed.
A musician with 50 demos can anchor all of them before sharing for under $1 total. Registering all 50 would cost $65+ each or require batching. Anchoring first costs nothing meaningful; registering before commercialization costs the fixed fee.
