WISeKey International Holding Ltd. announced the launch of WISeArt, a certificate of authenticity — a non-fungible token (NFT) — that will live forever on the blockchain, unchanged and unchallengeable, as proof of the buyer’s ownership. A WISeKey NFT is a unit of data on the blockchain, where each NFT represents a unique digital item, such as an artwork, audio, video, an item in video games or other forms of creative work. While digital files themselves are infinitely reproducible, NFTs representing them are traced on their underlying blockchains and provide buyers with proof of ownership.  Blockchains such as Ethereum, Bitcoin Cash and Flow, each have their own token standards to define their use of NFTs. NFTs can be used to commodify digital creations, such as digital art, video game items, and music files. Art creators have been using NFTs to capitalize on their work through cryptographic tools, but concerns and questions remain about authorship, authenticity and who could claim sole rights over the art. WISeAuthentic blockchain, provides brands with the ability of: issuing a storage device comprising of a digital certificate of authenticity; checking, when required, the validity of the digital certificate of authenticity; and modifying, when required, the status of validity of the digital certificate of authenticity.
