German start-up develops physical NFT
The start-up announces an NFT product: a sticker that links a physical object to a digital certificate of ownership.

Chemnitz, 9 February 2022 –
The startup authentic.network announces its NFT product launch. Together with co-founder Christoph Jentzsch, a pioneer in the blockchain and DAO community, the startup has developed a new type of crypto-optical code. With its help, physical objects can be transferred to the digital world using NFT.
NFTs – digital certificates of authenticity and ownership
NFTs (non-fungible tokens) are already firmly established in the tech scene to declare ownership of digital assets and make them tradable. Based on its patented technology, the Chemnitz startup now offers the possibility of creating NFTs for physical objects. With gummy, its latest product, an NFT for physical objects can be generated via the special sticker.
Stick it: the gummy is stuck to the physical object and thus acts as an analog anchor and information carrier for the digital certificate of ownership, the NFT. Own it: the gummy is scanned with a smartphone using the app developed by authentic.network, thereby generating the associated NFT. Trade it: the connection of the physical object to its NFT via gummy is thus complete. From now on, the product can be traded on crypto marketplaces, used on Web3, or otherwise presented digitally.
gummy – the physical NFT sets new standards in virtual trading
Every unique product will exist in the form of an NFT in the future. So far, the NFT market has been booming purely in virtual space. We're changing that with gummy, the physical NFT. We transfer physical objects into the digital world using a copy-protected and non-transferable sticker and make artworks, artifacts, products, or whatever is available as NFT on the Web3.
