Digital certificates of authenticity
NFT's are tokenized versions of an asset, digital or otherwise.
They can be used to represent nonfungible assets like artwork or collectibles or used in online applications & games.
The security level of the blockchain makes NFT's ideal to provide for certificates of authenticity that could be implemented in many use cases.
Providing Digital certificates to art makes it safe & easy for owners to auction, sell or transfer ownership without any intermediate party.
