PixelPlex has developed a Flow-based NFT marketplace for opal gemstone enthusiasts, which possesses three different non-fungible token types. The solution aims to enable fruitful interaction among opal fans and domain experts, as well as laying the foundation for an entire specialized opal metaverse (Opalverse).

Project goals

Together with the client, we established the key project goals:

  • 1

    Develop a high-performing NFT platform facilitating smooth NFT minting, auctioning, hosting, and trading

  • 2

    Provide the basis for a mini-metaverse where users will be able to mine and trade opals and enjoy unique experiences

  • 3

    Create an advanced, well-structured NFT model

  • 4

    Enable opal enthusiasts to do away with bureaucracy and operate more effectively with mining organizations

Work done

  • A robust NFT marketplace intended for opal gemstone fans

  • Ideation and creation of three different NFT types to be used within the platform

  • Development of a strategy and mechanism aimed at simplifying interactions between mining companies and opal enthusiasts

  • Integration with third-party services, including specialized education centers, KYC, a digital wallet, and a shipping service

  • Hyperledger-powered digital ledger for storing transaction data

  • Implementation of the escrow mechanism for insuring users against fraud and minimizing the risk of losing money or gems

  • Convenient web UI for the platform’s users and administrators

Project background

People have always been interested in investing in precious metals like gold and silver. However, these are largely dependent on stocks, and their prices tend to fluctuate a lot, which is why they are viewed by some as a risky investment.

Opal gemstones, on the other hand, are a rare commodity whose price has been steadily growing over time. The demand for opals has been high and the pandemic has also contributed to the increase in their popularity. During the January-July 2021 period, sales of the precious stone on Opal Auctions were up by over 46% compared to the same time period in 2020.

What makes opal gemstones a good investment?

  • Widely used in jewelry production
  • Scarce commodity that is impossible to industrialize due to the way it is sourced
  • Its value is independent of share and property prices
  • Opportunity to diversify an investment portfolio and own a real gem that you can touch

Business opportunity

The client, a keen and experienced opal gemstone enthusiast, came up with a ground-breaking idea that could potentially tackle the most pressing challenges inherent to gem mining and trading, and reached out to the PixelPlex team to polish it and bring it to life.

Despite all their unique characteristics and benefits, opals are challenging to mine. In America, for example, to extract gems on a certain territory, you need to contact a claim owner or mine staff operating on the site and deal with heaps of red tape that comes with becoming a claim holder yourself. Importantly, you need to apply for a special education program and learn how to properly mine opals via the MSHA. As well as this, due to the pandemic, some opal claim holders require appointments before non-claim-holders can mine.

Another aspect worth highlighting is that there is no single, unified, secure platform that would bring together all opal collectors, sellers, buyers, and mining organizations, and enable them to seamlessly and safely interact with each other, trade and showcase precious stones, and document a clear, detailed origin history for each gem. Plus, there’s no platform that offers mining collectives ownership via DAO governance tokens.

Solution

We have delivered a sophisticated NFT marketplace with metaverse-like features and an elaborate NFT model that empowers opal collectors to mint, auction, and trade 2D and 3D representations of mesmerizingly beautiful opals that contain detailed information about each stone.

The solution also possesses a hard asset NFT functionality, meaning that platform users can enjoy digital images and videos of their opals and also have the physical stones delivered right to their doorsteps.

Crucially, together with the client we developed and implemented a special shareholder NFT functionality that makes it easier and less time-consuming to gain permission to mine opals on a particular site.

Details

Our journey started with mapping out a detailed vision & scope document that foresees all challenges and risks, and selecting the most appropriate blockchain for the NFT platform.

Got an idea? Let’s work together

Discovery phase

First of all, we conducted an all-encompassing discovery phase which helped validate the project’s strategy. Our team has:

  • advised on the most appropriate tech stack
  • mapped out the application architecture
  • provided detailed industry-specific security measures
  • outlined integration with third-party service providers
  • identified functional and business needs for successful project development
  • described the NFT functionality

After agreeing with the client on the NFT marketplace’s core architecture, functionality, and third-party partners, we then decided to proceed with an MVP in order to deliver the solution to the market faster.

Why Flow?

Upon exhaustive research executed by our blockchain consulting team, we advised the client to opt for the Flow blockchain for the following reasons:

  • Easily scalable and perfectly suitable for building NFT apps
  • High transaction speed (around 65,000 tps)
  • Low transaction fees (starting at 0.000001 FLOW which is close to $0)
  • Treasury account and Flow USDC-multichain USDC Swap API is designed to meet the needs of wallets, exchanges, custodians, and other digital dollar stablecoin applications, reducing the friction to convert USDC across supported chains at no cost

Flow splits the work of processing transactions into four separate nodes that each have their own role and responsibility. Instead of relying on off-chain solutions to scale the network, Flow’s native node subdivisions give it a great advantage in blockchain scalability.

Sophisticated NFT model

When the client presented their idea to us, we realized that the solution required a multifaceted NFT model which could fulfill the project’s objectives. That is why we developed three non-fungible tokens, each of them performing its own separate function:

  • A blue and green icon of a cube

    Art/collectible NFT

    A digital 2D or 3D representation of an opal that can be a photo or GIF of a rare gemstone. The given NFT type contains detailed information about the opal’s origin, size, value, trading history, and many other important aspects.

    An art NFT can be minted, auctioned, displayed, and traded on the NFT marketplace.

  • A blue and green icon of a gemstone

    Hard asset NFT

    This is a non-fungible token that is underpinned by a physical opal gemstone. The holder of an asset-backed NFT can not only enjoy the benefits of having full ownership over a digitally represented opal but also opt to have it delivered right into their hands to enlarge their physical collection. Gemstone delivery is possible thanks to the NFT marketplace integration with a shipping service provider.

  • A blue and green icon of a pickaxe

    Private shareholder NFT

    To mine opals, one needs to contact a special organization engaged in trading shares that permit opal devotees to extract stones on their territory. The process of sealing deals with these shareholders is time-consuming and mundane, leaving many gemstone seekers dissatisfied.

    With regard to this, we have developed a private shareholder NFT. This token type represents a share belonging to a certain mining landowner and can be bought by the platform’s user to gain access to digging stones. A private shareholder NFT simplifies the process of transferring rights to shares and contributes to better efficiency.

Key ecosystem participants

  • Users

    NFT marketplace users have the ability to register on the platform, display, put up for sale, trade, and buy both collectible and asset-backed opal gemstone NFTs.

  • Shareholders

    These participants are mining collectives or owners of mining lands who sell or rent their shares to the platform users who want to mine opals on their territory.

The main user roles

Admin

The platform owner who is empowered to manage the content and users of the NFT marketplace.

Guest

An unregistered user of the platform who can view the content available on the platform. To buy or sell a token, a guest will need to register on the platform.

Mining collective

NFT traders

Users who have been registered and verified on the platform.

NFT traders can be:

  • Individual shareholders/family owned companies with patent claims
  • Mining collectives who don’t own a patent on the claim but have a precious mined opal
  • Social media mining collectives
  • Mines with jewelry/precious stones that are sold online
Store owner (vendor)

Business representatives who have been registered and verified on the platform. Vendors represent existing and new stores which trade opals and/or are interested in trading them as NFTs.

To be continued… Opal metaverse is underway

The NFT marketplace developed by the PixelPlex team for fans of opal stones has set the stage for an immersive opal metaverse (Opalverse) that has been proposed and ideated by the client.

Together we intend to ramp up our efforts and are already hard at work creating an entire metaverse space where gemstone aficionados will be able to unleash a range of extraordinary experiences, namely:

  • Display, view, and interact with unique opal gems in virtual showrooms
  • Set off on exciting trips to digital opal mines and search for gems there
  • Conduct and participate in thematic virtual workshops and meetups
