  • What is a Digital Passport?

    A digital passports is a digital image of a real-life object. We say that the object was “tokenized”. Tokenization is the process of converting an asset into a token that can be stored on a blockchain. Virtually anything can be tokenized, be it a digital, physical or intangible asset.

    Real-world assets (for example, fashion products and luxury watches) are linked to digital equivalents that have unique qualities such as evidence of ownership and authenticity, resistance to manipulation, and following the object throughout its lifecycle, even if it changes hands.

  • What are some important things to know about digital passports?

    Each digital passport has a digital signature, which is crucial to prove authenticity.

    Also, each Digital Passport will be specific to a particular real-life object; the twin points via a URL to this object’s digital image.

    Twins 'exist' on blockchains and this is the way the uniqueness and ownership can be verified.

    Each digital twin is unique and numbered.

    Finally, digital passports are underpinned by smart contracts and these contracts use varying 'standards'; Unikbase uses the ERC-721 token standard.


    Physical proof of an item's ownership and value might be misplaced, taken, or falsified.

    By registering your valuable item yourself or by transferring the passport from the previous owner to the new owner when the item has already been registered (especially by the manufacturer/brand itself), Unikbase enables you to save all of your valuable item's data and supporting documents in a single, non-duplicatable, unforgeable, and strictly confidential digital wallet.

  • I own a valuable : Why own a digital twin of it?

    Real-world assets (for example, fashion products and luxury watches) can now be linked linked to digital equivalents that have unique qualities such as evidence of ownership and authenticity, resistance to manipulation, and following the object throughout its lifecycle, even if it changes hands. 4 reasons to believe:

    • Demonstrate ownership
    • Authenticate the worth of your things
    • Manage your valuables in an effective manner
    • Take use of dedicated services
  • I'm a merchant : why propose digital passports to my customers ?

    To safeguard those who purchase valuables by allowing them to check the veracity of the information given by the vendor.

    To rebuild trust in the valuables market, which has been eroded by theft and counterfeiting.

  • How are my digital twin and my real-life collectible connected?

    Our end-to-end solution works in 2 steps:
    1) we take high resolution photos or 3-D scan the collectibles that cannot be tweaked.
    2) we tag the real-life object with an invisible ink that marks your products with 1.3 billion unique signatures. Marks can only be verified using our Unikbase UVB flashlights and / or chemical analysis and we will store the photo of the mark within the twin.

  • Can I use my digital twin to insure my valuable, or to report it stolen?

    Absolutely! Unikbase twins are accepted by some major international insurance companies. Besides, judicial authorities rely on the technology of our partner Olnica's tagging solution (part of Socomore group) in counterfeit and theft cases.

  • What are the environmental costs of creating a digital twin?

    Unikbase operates on a private blockchain named liquichain.

    Blockchain has raised environmental concerns.

    The energy consumption is huge and may cause increased carbon emissions and climate change. This causes other technological issues: blockchain is slow and transfers little.

    Liquichain is a blockchain whose nodes form a graph of trust and proximity. It is designed to run smart contracts in a fast, secured, and low energy consumption way, allowing to implement crypto currency, mobile micropayment, voting systems, file sharing, business processes and more.

    By redesigning the trust path among peers (Proof of Peers), Liquichain has both cracked the environmental issue and provided an agile community tool.

  • What is a Blockchain?

    A distributed public, peer-to-peer ledger that stores transactions is known as a blockchain.

    A blockchain is just a network of interconnected computers, or "nodes," which eliminates the need for a central hub, making it more secure, reliable, and harder to modify data. It cannot be altered and cannot be tampered with.

    There are now several different blockchains; Unikbase uses Liquichain.

    On each chain, a predetermined number of nodes must approve a transaction before it can be included in the chain permanently.

    Gas costs must be paid in order for the chain to change.
