A non-interchangeable token is a cryptographic certificate of a digital object with the ability to transfer the certificate through a mechanism used in cryptocurrencies. The token itself is not a proof of ownership of a digital asset in the context of copyright law. The NFT does not prevent the copying of the object, it only assigns to the owner a "digital token" created from one of the copies of the digital artifact. In order to draw maximum attention to the product and arouse interest in the cryptocurrency community, we were pleased with the decision to incorporate NFT into the Save Planet ecosystem. NFTs - have unique features and give us the ability to clearly know the wallets of those users who own them to list deductions. Secondly, NFT collections are a great tool to draw attention to the global problems of our planet, because there are no NFTs related to environmental protection on the web 3. Our team is going to release four NFT collections during 2023, the number of NFTs in each collection will be strictly limited to 250. Each collection will focus on a different global issue, and the owners of our NFTs will receive a huge range of benefits, even before the launch of the platform.
