Exploring Breakthrough Applications for NFTs Spanning Identity, Credentialing, Gaming, Physical Assets and More | by Blockchain Today | Dec, 2023

Non-fungible tokens (NFTs) built on blockchain allow direct digital ownership of unique assets and have so far been associated mostly with digital art and collectibles. But the underlying provable scarcity and authentication capabilities NFTs unlock enable far more than just representing JPEGs or avatar images.

In this comprehensive analysis, we dive into emerging and conceptual NFT-based systems powering identity services, credentials, physical item tracking, authorized access, community coordination and much more. By exploring these extended applications, we gain deeper perspective on how NFT innovation promises to streamline ownership and verification across diverse economic and social functions.

While current NFT models are early and speculative, their trajectory hints at profound shifts rethinking digital property rights and relationships through blockchain-enforced uniqueness, transparency and interoperability. NFT uses today likely pale compared to long-term potential.

NFTs Explained — Digital Uniqueness on Blockchain

We should first briefly explain what NFTs represent technically before detailing applications. In essence:

• Non-fungible tokens are unique blockchain assets with digital scarcity and ownership provenance. Unlike cryptocurrencies, each NFT differs from the next rather than being interchangeable. This makes them provably one-of-a-kind or limited editions.
• Data linking an NFT to a specific asset is recorded on a blockchain ledger to trace authenticity and origin. Owners possess the NFT token itself as proof of ownership.
• Metadata attributes define properties like images, 3D files, attributes, specifications, permissions, commercial rights, etc. that pertain to the underlying asset the NFT represents. An NFT could represent nearly anything in the physical or digital realm by binding it to recorded blockchain data.
• Interoperable token standards like ERC-721 allow NFTs to move freely across compatible blockchains, marketplaces and applications rather than siloed within proprietary platforms. This fluidity expands…
