Navigating the Territory of Fully On-Chain NFTs World

Table of Contents
The non-fungible tokens (NFTs) have taken the digital world by storm, revolutionizing the way we perceive and interact with digital assets. While the concept of NFTs is still in its nascent stages, it has already demonstrated its transformative potential, captivating the attention of collectors, investors, and enthusiasts alike. Among the various types of NFTs, fully on-chain NFTs stand out as a unique and promising technology, poised to shape the future of digital ownership.

I.  Fully On-Chain NFTs: A Shift in Digital Ownership

Within the diverse tapestry of NFTs, fully on-chain NFTs emerge as a unique and groundbreaking technology, poised to shape the future of digital ownership. Unlike traditional NFTs, which often rely on external servers to store their metadata and assets, fully on-chain NFTs reside entirely within the blockchain ecosystem. This self-contained nature offers a myriad of advantages, addressing some of the inherent limitations of off-chain NFTs.
The Anatomy of Fully On-Chain NFTs
To fully grasp the significance of fully on-chain NFTs, it is essential to delve into their underlying architecture. At their core, fully on-chain NFTs are characterized by three fundamental aspects:
  1. On-chain Assets: Unlike off-chain NFTs that store assets on external servers, fully on-chain NFTs embed the assets directly within the blockchain. This ensures that the assets are permanently accessible and cannot be manipulated or lost. For example, calling the tokenURI function on Bored Ape Yacht Club’s contract returns a pointer to an off-chain resource, in this case, IPFS.
  2. On-chain Metadata: Metadata, which provides information about the NFT, such as its name, description, and attributes, is also stored directly on the blockchain in fully on-chain NFTs. This eliminates the dependency on external servers and guarantees the integrity of the metadata.
  3. On-chain Rendering: In contrast to off-chain NFTs that rely on external servers for rendering, fully on-chain NFTs can be rendered directly from the blockchain data. This enables seamless viewing and interaction with the NFT without the need for external intermediaries.

The Enduring Promise of Fully On-Chain NFTs
The fully on-chain approach to NFTs presents a compelling value proposition, offering several distinct advantages over off-chain counterparts:
  • Permanence and Immutability: Fully on-chain NFTs are inherently permanent and immutable. As long as the blockchain exists, these NFTs will remain accessible and unverifiable, ensuring that ownership remains intact.
  • Decentralization and Self-Sovereignty: By residing entirely on the blockchain, fully on-chain NFTs eliminate the reliance on centralized servers, fostering decentralization and empowering individuals to maintain control over their digital assets.
  • Composability and Innovation: The on-chain availability of metadata and artwork data opens up new possibilities for interoperability and innovation. Fully on-chain NFTs can be integrated with other smart contracts, enabling the creation of novel applications and experiences.

II. Why doesn't every NFT do this?

Despite the compelling advantages of fully on-chain NFTs, there are several practical reasons why not all NFTs adopt this approach. These challenges stem from the inherent nature of blockchain technology and the limitations of current infrastructure.
Storage Limitations
One of the primary challenges hindering the widespread adoption of fully on-chain NFTs is the storage limitations of blockchains. Blockchains, by design, are inherently limited in their ability to store large amounts of data. This poses a significant constraint for storing large-scale assets, such as high-resolution images or videos, directly on the blockchain.
To illustrate this challenge, consider the storage requirements of a high-resolution image. A typical JPEG image with a resolution of 2048x2048 pixels can occupy around 3MB of storage space. While this may seem insignificant, when dealing with collections of thousands or even millions of NFTs, the storage demands can quickly become overwhelming.
Transaction Costs
The cost of minting fully on-chain NFTs is another factor that contributes to their limited adoption. Minting an NFT involves creating a unique record on the blockchain, which requires the execution of a smart contract. The execution of smart contracts incurs transaction fees, which can be substantial, especially on popular blockchains like Ethereum.
In the context of fully on-chain NFTs, the transaction fees associated with minting can be significantly higher compared to off-chain counterparts. This is because the data being stored on the blockchain, including the asset itself and its metadata, contributes to the overall size of the transaction, which in turn drives up the transaction fee.
Scalability Challenges
The scalability of blockchain technology also plays a role in the limited adoption of fully on-chain NFTs. Currently, most blockchains struggle to handle large volumes of transactions efficiently, leading to congestion and network slowdowns. This can make it impractical to store and render large assets directly on the blockchain, as it would further exacerbate the scalability issues.
Mitigating Challenges and Embracing Innovation
Despite these challenges, the potential benefits of fully on-chain NFTs are driving efforts to address these limitations. Researchers and developers are exploring various solutions, such as data compression techniques and novel storage mechanisms, to enhance the storage capabilities of blockchains.
Additionally, the development of layer-2 solutions, which operate on top of blockchains to improve scalability, is also promising. Layer-2 solutions can provide the necessary bandwidth and transaction processing capacity to make fully on-chain NFTs more feasible.

III. Benefits of fully on-chain NFTs

Despite these challenges, fully on-chain NFTs present a compelling value proposition, offering several distinct advantages:
  • Assets on-chain: Fully on-chain NFTs eliminate the reliance on external servers, ensuring that the assets are always accessible and cannot be tampered with or lost.
  • Immutable and everlasting: As long as the blockchain exists, fully on-chain NFTs will remain intact, providing a guarantee of permanence and immutability.
  • Composability: The on-chain availability of metadata and artwork data enables interoperability between fully on-chain NFTs, fostering creativity and innovation.

IV. Examples of Fully On-Chain NFTs

Several notable NFT projects have embraced the fully on-chain approach, showcasing its potential:
