Terms of Service

Proof is a service operated by Orange-Hat, LLC (“we”, “us”) that lets you create a cryptographic fingerprint of text or a file and optionally anchor that fingerprint to the DigiByte blockchain. By using Proof you agree to these Terms.

Proof is not legal advice, a notary, an attorney, or a guarantee that a court will accept your proof as evidence. It produces cryptographic timestamps, not legal validity. For important matters always consult a qualified professional in your jurisdiction.

You retain full ownership of any text or file you prove. Proof never stores a file you prove: it is read in memory to compute a unique SHA-256 fingerprint, and only the fingerprint and file name are kept. The text of a text proof is stored and shown on its public page. The title, description, and fingerprint you submit are stored on our servers and shown publicly. If you choose to stamp, the fingerprint is recorded on the DigiByte blockchain, where it becomes permanent and public.

You represent that you have the right to record a fingerprint of any content you submit.

You agree not to use Proof to:

• Record content you do not have the right to record (including copyrighted material you don’t own)
• Submit text, or a title, description, or filename, that is unlawful, harassing, or deceptive, or that publishes someone else’s private information
• Attempt to disrupt, probe, or abuse the service
• Resell or rebrand the service as your own

Anyone can report a proof from its page. We review reports by hand, and we may remove a proof that breaks these terms: its page stops being public and we tell its signer. A fingerprint already on the blockchain cannot be removed.

Stamping a proof writes its fingerprint to the DigiByte blockchain. Once written, we cannot delete or change it. It is maintained by thousands of independent computers worldwide. You should only stamp content you’re comfortable having in a permanent public record.

Stamping a proof to the blockchain requires a fee in DigiByte (DGB), payable to a one-time address generated for your proof. Fees are non-refundable once the blockchain transaction is broadcast.

Stamp fees and any voluntary tips go toward running Proof, covering DigiByte network costs, hosting, and ongoing development, and a share of each stamp fee is donated to the DigiAsset for Windows pool. Fees are subject to change with notice.

Proof is provided “as is” without warranty of any kind. We do not guarantee the service will be uninterrupted, secure, or error-free. To the maximum extent permitted by law, Orange-Hat, LLC is not liable for any indirect, incidental, or consequential damages arising from your use of the service.

Proof authenticates users via Digi-ID, a DigiByte-based signing protocol. Your identity on the service is your DigiByte address. You are responsible for keeping your wallet and private key secure. If you lose access to your wallet, we cannot recover your proofs or sign on your behalf.

We may update these Terms from time to time. Material changes will be announced on the site. Continued use after changes take effect means you accept the new Terms.
