  • Publication number: 20220270084
    Abstract: An NFT (non-fungible token)-Blockchain remote service is implemented, which receives social media posts, content, metadata, and other data to enable content owners, sponsors, and commentators to access and market content independently from initial social media platforms. The NFT-Blockchain service may interoperate with an NFT-Blockchain application instantiated on a user's computing device (e.g., smartphone, tablet, laptop, or personal computer) or may alternatively be a plugin, such as an extension to the user's browser application. Social media posts may be retrieved from respective social media platforms, NFTized, and added to a blockchain to establish the immutability and marketability of the post. A main system wallet associated with the NFT-Blockchain service may be established and utilized to receive money transfers from owners for the NFTization of their posts and compensation for other administrative tasks, such as NFT transfers.
