How NFTs, SFTs, and SBTs Differ in Fungibility and Use
Summary
The article compares three blockchain token categories by transferability, uniqueness, and intended use. NFTs are described as unique, indivisible assets whose ownership history can be tracked. SFTs begin as interchangeable units, making them suitable for bulk issuance, and may become distinct after use or another specified event. The text gives tickets, gaming items, and collectibles as examples of this transition and argues that batch handling can make SFTs more efficient than issuing many separate NFTs.
SBTs are presented as non-transferable tokens attached to a person or account, for credentials, achievements, or reputation. A comparison table summarizes the categories and illustrates their differing roles. The explanation is conceptual rather than technical: it does not specify token standards, implementation details, security assumptions, or measured costs. Its broad claims about efficiency and future applications are not supported with comparative data, and actual behavior can depend on how a particular token system is designed.
Key ideas
- NFTs represent distinct assets and are not interchangeable one-for-one with other tokens.
- SFTs can be issued as interchangeable units and later become unique under defined conditions.
- Batch issuance can make SFTs useful for tickets and other assets distributed at scale.
- SBTs are designed to remain bound to an account as credentials or records.
- Token behavior and practical costs depend on the implementation, which the article does not analyze technically.
