Copyright your software, app, or codebase.
Lock the source.
For indie developers, software studios, startup founders and open-source maintainers. Timestamp your codebase, web app or mobile project to a public blockchain — proof that survives long after the project does.
Why software needs a copyright certificate
Code is copyright the moment it's written, but enforcement is brutal without proof of authorship. Stolen apps republish under different names. Open-source contributions get re-licensed. Stack Overflow answers turn up verbatim in commercial products. The blockchain timestamp is your independent witness.
Mobile app cloning
Your iOS / Android app is rebuilt with a different name and launched on the App Store / Play Store within weeks. Without prior copyright proof, takedown is slow.
Codebase theft on GitHub
Forks get private, renamed, and rebranded as original work. Public verification links beat the "git log" defense.
License violation enforcement
AGPL, GPL, MIT — your license only matters if you can prove authorship. Certificates anchor your enforcement claim.
Contract / freelance disputes
Did you write this module for the client, or was it your existing library? A timestamped certificate from before the engagement settles it.

"I register every open-source project before publishing it. The certificate link goes in the GitHub README. If anyone ever claims my work as theirs, the public verification link settles it in 30 seconds."
Common questions about software & code
How do I package my entire codebase for upload? +
Use git: `git bundle create my-project.bundle --all`. This produces a single file containing your complete repository history. Or simply `zip -r my-project.zip .` for a snapshot. Both are accepted up to 5 GB.
Does copyright apply to source code in every language? +
Yes — under the Berne Convention, all original source code is copyrightable regardless of language. Whether it's C, Rust, Python, JavaScript or COBOL, the same protection applies.
What about open-source code I depend on? +
Their copyright stays with them — your copyright covers only your original contributions. When bundling your project, you don't need to remove dependencies; the certificate explicitly applies to your authored portions.
Can I register iterative versions of my project? +
Yes — version tracking links V1 → V2 → V3 to a single chain. Typical workflow: register every major release. Useful for proving when specific features first appeared.
Does this work for App Store / Play Store disputes? +
Yes. Apple and Google's legal teams accept third-party copyright certificates as evidence of prior authorship in takedown requests. Include the verification link in your DMCA / counter-notice.
