Protect your intellectual property and sensitive documents

No. Only the digital fingerprint (hash) of the document is stored on the blockchain, not its readable content. Waipal does not store the actual file on the public blockchain network.

The certificate can serve as supporting evidence when proving the existence, form or ownership of a document. It is not a substitute for legal protection, but it helps document key facts.

Yes. Waipal is suitable for companies, entrepreneurs and individuals who want to protect important documents, know-how or creative works.

Encryption protects the content of a document so that it cannot be read without the appropriate authorisation. Your files remain protected even if someone attempts unauthorised access.

The price of a certificate starts from 79 CZK and depends on volume. You can find the current pricing at waipal.com.

Blockchain is a distributed database of records that is decentralised and immutable. Each record is cryptographically linked to the previous one — any change would be immediately detectable. This makes blockchain records trustworthy and temporally indisputable.

Waipal uses an established public blockchain network that guarantees the permanence and verifiability of records. Specific technical details are available in the terms of service or on request at info@waipal.com.

Waipal creates a digital fingerprint (hash) of your file and records it on the blockchain with an exact timestamp. This proves that the file existed in a given form at a specific time — and no one can change that retroactively. For sensitive documents, we also offer encryption that protects their content from unauthorised reading.

Yes. All communication is encrypted via HTTPS. Only the digital fingerprint of the file is stored on the blockchain — the actual document content never goes to the public network. Your files are stored securely and accessible only to you.

Yes. You have full control over the encryption key for your documents. No one else — including Waipal — has access to the content of your encrypted files without your knowledge.

The certificate contains: the date and time the record was created, the digital fingerprint (hash) of the file, the blockchain record identifier (TX hash), the name or description of the file, and information about the owner including their identification. The certificate can be re-verified at any time at waipal.com/verify.

No. The blockchain record is permanent and independent of Waipal's existence. Even after you stop using the service, your certificate will remain verifiable via the public blockchain network. We recommend downloading and saving your certificate for future use.

Only you and people you explicitly grant access to have access to your files. Waipal does not have access to the content of your documents. Only an anonymous digital fingerprint is visible on the public blockchain — with no possibility of reconstructing the file content.

A Waipal certificate can serve as supporting evidence when proving that a specific document existed in a certain form on a given date. It helps prove authorship priority, the existence of a contract draft, or the wording of a document at a specific time. It is not a substitute for legal representation, but it can strengthen your evidentiary position.

Only the cryptographic fingerprint (hash) is stored on the blockchain — a one-way function from which the file content cannot be reconstructed. The actual data remains on our servers protected by encryption. The blockchain record is immutable and decentralised, so it cannot be deleted or altered.
