NFTs vs SFTs: Key Differences
Blockchain has evolved, and over the years, we have seen innovations in the web3 space, with NFTs being among the biggest. Both NFTs – and SFTs for that matter – lead in terms of redefining ownership and utility in the digital space, and they have helped shape industries such as modern gaming, art, real estate, and much more.
The primary focus of this content piece is to provide readers with an in-depth understanding of NFTs and SFTs. NFTs have gained widespread recognition for their role in the crypto industry, but SFTs are a very versatile counterpart that blends both fungibility and non-fungibility for different applications. Therefore, it is important to understand the differences between NFTs and SFTs for all enthusiasts, investors, developers, and collectors in the blockchain space.
What are NFTs?
Non-fungible tokens, NFTs, are a digital asset type built on blockchain technology. Unlike crypto, NFTs are unique and non-interchangeable. In essence, an NFT provides an ideal representation of one-of-a-kind items. The term “non-fungible” suggests that no two NFTs are identical. Each NFT has unique metadata that makes it different from the rest. Such an NFT can be anything: a piece of digital art, virtual land, virtual character, and so on. This is what makes NFTs unique.
An NFT is indivisible. NFTs cannot be split into smaller units. Instead, they are only traded as whole tokens. Additionally, NFT ownership and transaction history are permanently recorded on a blockchain. This makes them transparent and secure assets.
Use Cases
NFTs are not merely speculative assets. They have plenty of utility in various industries because of the ability to represent ownership of unique digital and physical assets.
NFTs have transformed the art world by enabling artists to monetize their work directly. Perhaps one of the best-known examples would be Beeple’s Every Day: The First 5000 Days,” which sold for $69 million at Christie’s. Artists can also gain royalties on secondary sales.
Besides that, NFTs gained momentum due to digital collectibles such as CryptoPunks and Bored Apes becoming NFT success stories. These collectibles serve as status symbols as well, where the holder of NFTs of a collection has access to communities, events, merch, and other advantages (i.e. airdrops).
In recent years, NFTs have seen usage from musicians as well. NFTs can help provide direct-to-fan revenue streams. Some artists have released albums and exclusive content as NFTs, with fans owning unique, limited-edition music assets.
NFTs have also helped fuel the web3 gaming sphere. In-game assets (i.e. weapons, skins, land) can be tokenized as NFTs, and players gain true ownership of these assets. They can then trade or sell them outside the game.
Last but not least, NFTs are now used for virtual real estate. People can buy, sell, and develop land parcels as NFTs. Moreover, some real estate companies also sell via the NFTs, so that the buyer would have ownership of real estate both physically and digitally.
How NFTs Work on the Blockchain
Powered by blockchain technology, users can create, store, and transfer NFTs. The first blockchain to come up with NFTs is the Ethereum blockchain. The latter remains one of the most used networks for NFTs, primarily using the ERC-721 token standard.
NFTs are created using smart contracts, which are self-executing contracts with the terms of the agreement directly written into code. These contracts define ownership, transfer rules, and any additional data associated with the NFT. This data includes crucial information such as a unique identifier for the token, ownership details and transfer history, and/or other links to external resources.
The first standard for NFTs is the ERC-721. This is the standard that makes digital assets unique and indivisible. Later on, other token standards were introduced. Every transaction involving ERC-721 tokens is recorded on the blockchain to ensure authenticity.
Today, NFTs can be used across various platforms and networks, and their versatility has made them highly applicable to some of the biggest companies in the world. Besides benefitting both businesses and creators, NFTs also help promote better communities by giving holders voting rights on how to shape the community.
In the sense of paradigm shifts in the digital space, crypto did its toll. But it is safe to say that smart contracts and NFTs did the same to the crypto market. They are building blocks for decentralized ecosystems.
What are SFTs?
SFTs, short for Semi-Fungible Tokens, are a hybrid approach of blockchain tokens that combines the characteristics of fungible and non-fungible tokens. SFTs function just as fungible tokens, meaning that they are interchangeable and have uniform value. But, under certain conditions, they can transition into non-fungible tokens and become non-interchangeable. Because of this dual functionality, SFTs can adapt to more applications than NFTs.
Most easily explained would be to say that SFTs are used when an asset needs to change its utility or state under a certain lifecycle. For example, a ticket to a virtual concert on the entrance to a certain community can be an SFT first, but when it is activated (or is past its lifecycle), it is turned into a unique, non-transferable item.
So, SFTs can be exchanged on a one-to-one basis with other identical tokens, but after certain conditions are met, SFTs become unique assets. This transition is seamless (from fungible to non-fungible).
The batch transfer capability of SFTs reduces transaction costs. SFTs can also be used for bulk operations (transfer on a large scale), unlike NFTs. SFTs use the ERC-1155 standard, meaning that developers can create both fungible and non-fungible tokens within one smart contract to reduce complexity and increase scalability.
Use Cases
Similar to NFTs, SFTs can also be used in a wide range of applications. For example, they can also be used in the gaming industry. In-game currencies can start as fungible tokens and transition to non-fungible items when upgraded (i.e. a weapon or skin with unique attributes).
SFTs also streamline the ticketing processes by starting as identical tickets and transitioning into unique assets after being redeemed. Additionally, SFTs enable businesses to create flexible rewards, such as exclusive discounts, perks, and much more. Last but not least, SFTs can represent other metaverse assets in items that are needed as fungible for trade purposes but there is also distinct ownership.
How SFTs Work on the Blockchain
As suggested SFTs use the ERC-1155 token standard. This combines the functionality of fungible tokens (ERC-20) with non-fungible tokens (erC-721_/
Similar to NFTs, SFTs include digital data that includes fungible and non-fungible attributes. The state of an SFT is managed by its smart contract, which updates the data as the token transitions from one state to the other. The use of the ERC-1155 standard has helped individuals and communities optimize resource usage so that token management is efficient across various web3 platforms.
But this makes SFTs more versatile than NFTs since they offer more adaptability, in addition to reducing gas fees for batch transactions. Hence, SFTs do have a broader market appeal, even though that may not necessarily be the case.
Still, SFTs represent another addition to the innovative space of crypto. With its hybrid approach, SFTs can be powerful tools for various industries that want to leverage blockchain technology for their applications.
Key Differences Between NFTs and SFTs
In a nutshell, there are plenty of differences between NFTs and SFTs. Here is a table that summarizes most of it:
Fungibility Comparison | NFTs: Always Non-Fungible | SFTs: Hybrid Fungibility |
NFTs are inherently non-fungible, meaning each token is unique and cannot be exchanged one-to-one with another token. This uniqueness is their defining characteristic and makes them ideal for representing exclusive assets like art, collectibles, and virtual real estate. | SFTs start as fungible tokens, identical and interchangeable with others of the same kind. However, under certain conditions, such as redemption or usage, they transform into non-fungible tokens, acquiring unique characteristics. | |
Technical Standards | NFTs: ERC-721 or Equivalent Standards | SFTs: ERC-1155 Standard |
NFTs are primarily built on the Ethereum blockchain using the ERC-721 token standard. This standard is specifically designed for non-fungible assets and ensures that each token is unique and indivisible. | SFTs leverage the ERC-1155 standard, a versatile multi-token framework that supports both fungible and non-fungible tokens. This standard enables batch transfers and unified contracts. | |
Use Case Differences | NFTs: Best for Unique, One-of-a-Kind Assets | SFTs: Ideal for Evolving or Multi-Stage Assets |
NFTs excel in scenarios where uniqueness and exclusivity are critical. Common use cases include digital art, collectibles, gaming items, real estate, and much more. | SFTs shine in scenarios where assets need to transition between fungible and non-fungible states. Examples include gaming, events, loyalty points, and many more. | |
Value and Exchange | NFTs: Individual Assets with Unique Valuations | SFTs: Uniform Value During the Fungible Stage |
The value of an NFT is often subjective, based on its rarity, desirability, or association with a specific creator or brand. For example, a rare NFT may be valued at millions due to its exclusivity and cultural significance. | In their initial fungible state, SFTs hold the same value as others of their kind, making them easily tradable and more liquid. However, once they transition to non-fungible assets, their value becomes unique and context-dependent. | |
Efficiency and Scalability | NFTs: Higher Costs and Complexity | SFTs: Cost-Effective and Scalable |
The indivisibility of NFTs means each must be managed, minted, and transferred individually. This results in higher gas fees and increased network congestion, especially during periods of high demand. | The batch transfer capabilities of SFTs allow multiple tokens to be minted or transferred in a single operation. This significantly reduces costs, making SFTs more practical for large-scale applications. | |
Lifecycle | NFTs: Static Lifecycle | SFTs: Dynamic Lifecycle |
NFTs remain non-fungible throughout their existence. They are minted as unique assets and retain their exclusivity indefinitely. | SFTs are designed with lifecycle flexibility. They can start as fungible tokens and transition into non-fungible assets based on specific conditions. This adaptability makes them suitable for use cases requiring evolving utility. |
So, while NFTs are best suited for assets that require permanent uniqueness, SFTs are ideal for apps where assets NEED to evolve over time.
