Disclaimer

Blockchain timestamps provide proof that a file existed at a specific time. They do not, by themselves, establish authorship or ownership. For stronger claims, link timestamps to your identity and consider formal registrations where applicable.

What Timestamps Prove

A blockchain timestamp proves that a specific file (represented by its cryptographic hash) existed at or before a particular time recorded on the Bitcoin blockchain. This is cryptographically verifiable and tamper-proof.

What Timestamps Don't Prove

• Authorship: A timestamp alone doesn't prove who created the file. You must link the timestamp to your identity (e.g., through your account, a digital signature, or other documentation).
• Ownership: Timestamps don't establish legal ownership or copyright. They only prove existence at a point in time.
• Content Authenticity: Timestamps prove when a hash was created, not the authenticity or originality of the content itself.

Legal Advice

This service does not provide legal advice. While blockchain timestamps are increasingly recognized in legal proceedings, their admissibility and weight as evidence varies by jurisdiction. For critical intellectual property matters, consult with a qualified attorney and consider formal copyright registration or other legal protections in your jurisdiction.

Best Practices

• Keep supporting documentation (drafts, emails, version history) to corroborate authorship.
• Link your timestamps to your identity through your account or digital signatures.
• For commercial work, consider pairing timestamps with formal copyright registration.
• Store your .ots proof files securely for future verification.
