Digital collection refers to the unique digital voucher corresponding to specific works and artworks generated by blockchain technology, which realizes authentic digital distribution, purchase, collection and use on the basis of protecting its digital copyright. In other words, a digital collection is a digital asset. Music, tickets, fun, cards, paintings, photos, GIF animations, emoticons and so on can all be used as digital collections.
Simply put, NFT is to put an "anti-counterfeiting code" on the work through blockchain technology, making it a unique digital token. Digital works can be traced back, and copyright can be clearly defined and traded.
