Blockchain Notary Service
Our service leverages blockchain technology to create an unalterable record of your digital file's existence at a specific point in time. This provides rock-solid evidence that can't be tampered with or disputed.
NFT-Based Proof
Leverage the power of Non-Fungible Tokens (NFTs) to create unique, transferable proofs of ownership for your digital assets.
Secure Without Exposure
Our service uses file hashing (SHA-512), ensuring that your actual file content never leaves your possession. Only the cryptographic hash is stored on the blockchain.
Timestamped Records
Each notarization includes a tamper-proof timestamp, providing indisputable evidence of when a file existed in its current form.
Notarize Any Digital File
Whether it's a document, image, video, or any other digital file, our service can create a blockchain-verified record of its existence and your ownership.

How It Works
File Hashing
You calculate a unique digital fingerprint of your file (SHA-512 hash) using our online tool or locally.
NFT Creation
We create a digital certificate (NFT) containing your file's fingerprint and mint it to your blockchain address.
Certificate Generation
You receive a PDF certificate with all important details and QR codes for easy verification and sharing.
Verification
Anyone can verify the file's authenticity by comparing its fingerprint with the one stored in the blockchain.
Examples
Notarization with Ownership
A web designer needed to prove the originality date of their website design mock-up. Using our service, they notarized a screenshot of their design, added a public link where the original file is stored, and included notes about the design's key features. By providing his blockchain wallet address, he received both a professional certificate and an NFT that proves their ownership and contains easy access to the original file.

Timestamped Notarization
Sometimes you just need to prove a document existed at a specific time, without concerns about NFT ownership. In this case, the user simply uploaded their document for timestamping, without providing a wallet address or additional details. They received a verification certificate that proves their document existed at that exact moment - perfect for intellectual property records or legal documentation.

Frequently Asked Questions
A blockchain notary service uses blockchain technology to create a tamper-proof, time-stamped record of a digital file's existence. It provides proof of ownership and authenticity without revealing the file's contents.
We create a unique Non-Fungible Token (NFT) for your digital file, which includes a hash of the file and timestamp. This NFT is then recorded on the blockchain, providing an immutable record of your file's existence and your ownership at that time.
You can notarize any type of digital file, including documents, images, videos, audio files, and more. The file itself is not uploaded; only its unique hash is recorded on the blockchain.
Prices start from $0.10 per NFT when using our web app, with a minimum payment of $10. For our native mobile apps, prices start from $1 per NFT. Bulk notarization can provide additional cost savings.
You can verify a notarized file through our web portal or mobile app. Simply upload the file or input its hash, and our system will check the blockchain for the corresponding NFT record, confirming its timestamp and ownership.
Yes, your file content remains completely private. We only store a cryptographic hash of your file on the blockchain, not the file itself. This hash acts as a unique fingerprint of your file without revealing its contents.
Yes, since each notarized file is represented by an NFT, you can transfer ownership of this NFT to another blockchain address. This transfer is recorded on the blockchain, providing a clear chain of ownership.
We currently use Polygon for our notarization service. This blockchain was chosen for its security, reliability, and widespread adoption.
The notarization process typically takes a few minutes, depending on blockchain network congestion. Once the transaction is confirmed on the blockchain, your file is officially notarized and you'll receive a confirmation.
