About Blockchain Verified
Blockchain Verified Sweden AB provides blockchain-based document verification used by organizations worldwide. Our solutions deliver tamper-evident document authentication tailored to your business and compliance needs.
Companies use Blockchain Verified to protect invoices, certificates, contracts, and test reports against document manipulation. Each file receives a unique digital fingerprint anchored to the blockchain, allowing instant verification of its authenticity.
This creates immutable audit trails and compliance-ready documentation, helping finance, legal, and compliance teams prevent document fraud and prove that documents remain unchanged.
Securing your document
When a PDF is attested, a unique digital fingerprint (hash) is created and recorded on the blockchain. If the document changes, the fingerprint changes, instantly revealing tampering.
Even small edits made with PDF software can alter certificates, reports, or contracts without being easily visible. Blockchain Verified detects these changes and proves document authenticity.
The result is tamper-evident, blockchain-verified documents, bringing Finance, Accounting & Test, Inspection and Certification into a secure Web3-ready standard.
How does it work?
Attest
The document's unique digital fingerprint is securely recorded on the Ethereum blockchain via a smart contract, creating immutable proof of authenticity.
Attested
The document becomes tamper-evident and immutable, creating a permanent reference to verify its authenticity.
Confidential
The document contents are not stored on the blockchain, only the digital fingerprint. The document itself remains private secure and fully confidential.

Advantages
Blockchain Verified instantly confirms whether a document is authentic. No manual comparison with databases; our system verifies the file itself.
Each document receives a blockchain-recorded fingerprint on Ethereum, creating tamper-evident proof of integrity. A 700-page report verifies as quickly as a single certificate.
The platform is decentralized, secure, and confidential. Documents remain private, while the system detects tampering and even identifies newer document versions.
Built by experts from IT, finance and accounting, test, inspection and certification industries,, Blockchain Verified delivers trusted document authentication for compliance-critical environments.
