Not All Tokens Are the Same: NFTs vs SFTs vs SBTs
With the rise of digital assets and blockchain tech, you've probably heard about Non-Fungible Tokens (NFTs) and Semi-Fungible Tokens (SFTs). Although they sound similar, each type of token has distinct features and serves different purposes. This article explores clearly and simply what sets NFTs apart from SFTs and how each is used.
What Are NFTs (Non-Fungible Tokens)?
Non-Fungible Tokens (NFTs) are unique digital assets secured and verified using blockchain technology. Each NFT represents something one-of-a-kind and irreplaceable, such as digital art, collectibles, virtual real estate, or individual gaming items. NFTs became widely popular for their ability to confirm ownership and authenticity of digital items.
Key Characteristics of NFTs:
● Uniqueness: Every NFT is unique and can't be replaced by another identical token.
● Indivisibility: You can't split NFTs into smaller pieces—they always remain whole and distinct.
● Ownership Provenance: Blockchain records offer transparent proof of ownership and history.
What Are SFTs (Semi-Fungible Tokens)?
Semi-Fungible Tokens (SFTs) combine aspects of both fungible tokens (like Bitcoin or Ethereum) and NFTs. Initially, an SFT acts like a regular token, interchangeable with others of the same kind. However, under specific conditions or after certain events, it becomes unique, shifting its status from fungible to non-fungible.
SFTs are particularly useful for gaming assets, tickets, and collectibles produced in large quantities that become unique through specific interactions or events.
Key Characteristics of SFTs:
● Flexible Fungibility: Initially fungible but can later become unique based on certain conditions.
● Efficiency: Less expensive and more efficient for batch transactions compared to NFTs.
● Dynamic Nature: Can change their fungibility status based on predetermined rules or interactions.
What Is The Difference Between NFTs vs SFTs?
Although NFTs and SFTs both live on the blockchain, their fundamental nature, usage, and efficiency differ in important ways. Let's break it down:
NFTs vs SFTs: Fungibility
● NFTs: Always non-fungible. Each token represents a unique asset and cannot be replaced or exchanged on a one-to-one basis with any other token.
● SFTs: Start off fungible—meaning any token is identical and interchangeable with another of the same kind—but under certain conditions, such as usage or passage of time, an SFT can transform into a non-fungible asset with its own distinct value.
NFTs vs SFTs: Use Cases
● NFTs: Perfect for applications where uniqueness and individual ownership are critical, such as digital art, rare collectibles, one-of-a-kind gaming items, and virtual land parcels. Every NFT stands as a singular proof of ownership over a specific digital or virtual good.
● SFTs: Best suited for situations requiring flexibility between bulk issuance and later individuality, such as concert tickets, event passes, gaming consumables, or batch-minted collectibles. Initially, all tokens may be identical, but they can evolve into unique items after certain interactions or milestones.
NFTs vs SFTs: Cost and Scalability
● NFTs: Because each NFT is minted as a standalone, unique item, handling multiple NFTs can lead to higher transaction fees and lower efficiency, especially when dealing with large volumes.
● SFTs: Offer significant cost and scalability advantages. Since they are minted in batches and treated as interchangeable at first, SFTs can be transacted more efficiently and economically, which is ideal for projects expecting high transaction volumes or mass distribution.
What Are SBTs (Soulbound Tokens)?
Soulbound Tokens (SBTs) are a special kind of NFT that cannot be transferred once minted to a wallet (see the image below). While typical NFTs represent tradable unique assets, SBTs are designed for use cases where identity, achievement, or trust must remain tied to a specific person or wallet — like academic degrees, reputation scores, or certifications.
Key Characteristics of SBTs:
● Non-transferability: Once issued, SBTs can't be transferred or sold.
● Personalized Ownership: Permanently linked to an individual or account, reflecting personal credentials or achievements.
● Proof of Identity: Useful in digital identity verification and credentialing systems.
Why Does The Difference Matter?
Knowing the difference between NFTs and SFTs helps you choose the right type of token based on your needs—whether it's absolute uniqueness and exclusivity (NFTs) or cost-effectiveness and flexibility for bulk items (SFTs). Additionally, understanding SBTs is crucial for applications that require permanent, non-transferable proof of identity or credentials.

A Quick Comparison
Practical Examples
NFTs
Unique, indivisible, transferable assets
A unique digital artwork sold on platforms like OpenSea, with ownership securely verified on the blockchain.
SFTs
Initially fungible but may become non-fungible; flexible and transferable
Event tickets for a concert that start out identical but become unique collectible items after they've been used.
SBTs
Permanently non-transferable and identity-bound
Digital diplomas or certificates that remain permanently tied to an individual's blockchain identity.
Conclusion
As blockchain technology continues to expand into new areas of our lives, the roles of NFTs, SFTs, and SBTs will only grow more significant. NFTs are redefining ownership and creativity, SFTs are unlocking scalable experiences in gaming, events, and commerce, and SBTs are laying the groundwork for digital identities and trust systems that could power future economies.
While NFTs, SFTs, and SBTs share common ground, their unique characteristics cater to different digital asset needs, therefore making it essential to clearly understand their differences. By mastering the nuances between these tokens today, you're preparing to participate in the next wave of innovation. No matter who you are or aspire to be, a creator, a gamer, a builder, or a visionary, learning to leverage these evolving tools will empower you to make informed choices and stay ahead as the digital landscape transforms. The future belongs to those ready to build it—one token at a time.
