About NFTCDN

NFTCDN is Cardano’s dedicated NFT Content Delivery Network, enabling products and services to display NFT media content easily, efficiently and at high-speed to their worldwide user base through our global CDN. Our capabilities include NFT Image Display delivery and Metadata Information provisioning, and we seek to introduce an API to enable products and services on Cardano to utilise the files component of an NFT, expanding the application of NFTs in the Cardano ecosystem, resulting in expansive growth in a variety of industries.

Problem Statement

Over 8.45 million NFTs have been minted on Cardano to date, and while the vast majority of these comprise of images in the form of digital art (using the “image” component of the NFT metadata), an emerging area is the application of the “files” component, wherein most notable use cases (henceforth referred to as “use-types”) have been for songs (audio files), movies, clips or exclusive footage (video files), books, documents, records or reports (pdf files) and bespoke projects (HTML and other file-types). This emerging area has seen an increase in utilisation of an NFT’s files component to hold assets by companies from the music, film, book and gaming industry - with ever evolving use cases. The challenge for products and services is the implementation of “fetching” and “display” capabilities of these files. 

Building an end-to-end capability to query and parse metadata across various NFT standards to secure NFT file information, fetch the file(s) from the respective storage areas (IPFS, Arweave, on-chain, HTTP, etc) and deliver the files (termed the “fetching” process) in a fast, efficient, reliable and seamless manner would cost c. $90,000 to develop and $10,000 per month to run - notwithstanding costs for CI/CD. 

The additional burden of building the capability to be able to display, without error, each of the file-types (audio, video, pdf, HTML, etc) in a manner that can be easily integrated within a product’s or service’s platform to fully realise the benefits for each use-type is not a sustainable endeavour for any new or existing project to undertake. 

This necessitates the creation of a capability such that products and services can seamlessly integrate NFT files with their platforms, enabling them and content creators to realise and utilise this core component of a Cardano NFT to its fullest potential.

Solution Design

The proposal aims to deliver a fetching (i.e. delivery of media content within the NFT files component of the NFT metadata), optimising (i.e. transcoding/rescaling to lower bandwidth needs and increase end user client-compatibility) and display (i.e. regardless of the file format, the ability to load said files within a browser) capability though a “Universal NFT File Viewer API endpoint”, which can be seamlessly integrated within a product’s or service’s platform through iframes.

In simple terms, by simply plugging in an NFT’s fingerprint ID within the Universal API endpoint, the end recipient will be able to view (i.e. open) NFT files contained within an NFT, irrespective of its use-type. NFTCDN will design, develop, test and deploy this capability as an outcome of this proposal.

Solution Scope & Limitations

At present, the following known MIME types exist for the most notable use-types within an NFT:

• Images (image/png, image/gif, image/webp, image/jpeg)
• HTML (text/html)
• 3D Models (model/gltf and model/glb)
• Documents (application/pdf and text/plain)
• Audio Files (audio/wav, audio/mpeg and audio/x-flac)
• Video Files (video/mp4)

As part of this proposal, NFTCDN will build a Universal NFT File Viewer API endpoint that will be compatible with the aforementioned MIME types.

[IMPACT] Please define the positive impact your project will have on the wider Cardano community.

Performance Measure & Output Results From Proposal

Our ultimate objective is the successful delivery of the Universal NFT File Viewer API endpoint. As per our milestones, we will develop the capability to be able to fetch and display NFT files for each of the use-types (Image, HTML, 3D Models, Documents, Audio Files and Video Files).

We will measure our performance against the 100% successful delivery of our developed solution’s capability to fetch and display the 6 use-type categories listed. The results output from our testing will be in the form of a viewer being able to display NFTs minted with the respective MIME types per use-type. We will share these outputs as part of our milestone reporting, including showcasing the results on the NFTCDN website.

Once ready for deployment on mainnet (i.e. the roll-up of all 6 use-type categories into a single universal API endpoint), our close-out report/video will additionally feature a working example of this feature within.

In addition to the above, the proposal will maintain regular monthly reporting on our progress, highlighting our progress over the course of our endeavour.

Benefit to Cardano

• By delivering this capability, we will empower content creators, products and services on Cardano to expand their offerings from simply digital art NFTs to broader real-world use cases by virtue of the availability and compatibility for use of a diverse range of file-types. This opens up NFTs within the Cardano ecosystem to new innovations, catalysing the growth of new product and service developments by those seeking a blockchain with versatility within its native asset capability, consequently growing the Cardano user base.
• Cardano will have a ready-to-use capability, allowing both new products and services to jump start their business, and existing ones to quickly adopt an efficient and seamless system without having to spend 12 months and the associated costs towards developing such a capability.
• The Universal NFT File Viewer API will be a holistic end-to-end media content display endpoint, able to be seamlessly and easily integrated within a product’s or service’s platform with minimal development effort, enriching their end-user’s viewing and engagement experience.
• Once delivered, this capability will be powered by NFTCDN - a trusted name in the Cardano ecosystem, with a reputation for quality, reliability and performance.
