Linke Network is a Web 3.0 social graph protocol aiming to link personal NFTs owned by the creator with the community NFT to form a fully composable, user-owned social graph. It enables the addition of new features and plugins, while ensuring that the content and social relationships of users are immutable. This provides a social graph and social functional components for a new generation of DApps to explore the new paradigm of people, organizations, relationships, and behaviors in Web 3.0.
