NFT Status

Each NFT in the system can have one of the following statuses, representing its current state in the notarization process:

  1. Pending:

    • The NFT creation request has been received and is waiting to be processed.
    • This is the initial state when an NFT is first requested.

  2. Sent:

    • The NFT creation transaction has been sent to the blockchain network.
    • The transaction is waiting to be confirmed and mined.

  3. Minted:

    • The NFT has been successfully created and recorded on the blockchain.
    • This status indicates that the notarization process is complete and the NFT is active.

  4. Transferred:

    • The NFT has been transferred to a different blockchain address.
    • This status is used when the ownership of the NFT has changed.

  5. Burned:

    • The NFT has been intentionally destroyed or made permanently inaccessible.
    • This status is irreversible and typically used when an NFT needs to be taken out of circulation.

  6. Failed:

    • The NFT creation process encountered an error and could not be completed.
    • This may occur due to various reasons such as network issues, insufficient funds, or invalid data.

Understanding these statuses is crucial for tracking the progress of your NFTs and managing them effectively through the API.

FAQ

  1. What is a blockchain notary service? A blockchain notary service uses blockchain technology to create a tamper-proof, time-stamped record of a digital file's existence, providing proof of ownership and authenticity without revealing the file's contents.

  2. How does NFT-based notarization work? 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.

  3. What types of files can I notarize? 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.

  4. Is my file content secure and private? 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.

  5. Which blockchain does your service use? We currently use Polygon for our notarization service. This blockchain was chosen for its security, reliability, and widespread adoption.

  6. How long does the notarization process take? 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.
