Please describe your proposed solution

Our proposed solution addresses a pressing problem in the Cardano NFT space - the inability to list NFTs on multiple marketplaces simultaneously. This lack of cross-marketplace functionality restricts visibility and opportunities for artists, developers, and sellers, while increasing the potential for market monopolization.

Our solution is a neutral smart contract-based service that allows NFTs to be listed across multiple marketplaces through reference assets.

This is our proposal of how it could work:

• The NFT is sent to a smart contract for sale.
• The smart contract proceeds to mint reference assets, one for each of the marketplaces the seller selects.
• The reference assets are listed on the selected marketplaces.
• When a sale is made, the original asset is transferred to the buyer, the payment goes to the seller, and all other listings are cancelled and the reference assets burned.

This system should also accommodate seller cancellation, ensuring the return of the original asset and termination of all listings.

We want to emphasise that our aim is to create a neutral, community smart contract, meaning one that is not owned and maintained by a single entity who ultimately gets to set its rules.

The innovation of this solution rests on its ability to level the marketplace playing field, increasing competition, enhancing exposure, and offering new possibilities. For instance, it could integrate on-chain royalties, making Cardano more attractive to creators as other ecosystems struggle with this aspect. Furthermore, it could extend to other services like native asset staking, creating a unique opportunity for assets to be offered for sale while earning rewards.

However, the effective implementation of this solution hinges on community agreement on the standards and methodology of our approach. That's why we're initially focusing on the development of a mutually agreed standard. Once this standard is established, we'll proceed with the development of the tooling itself. By this approach, we mitigate the risk of developing tooling that might not gain widespread adoption across Cardano's NFT marketplaces.

Please define the positive impact your project will have on the wider Cardano community

Our solution is unique as it addresses a specific issue within the Cardano ecosystem, enhances marketplace competitiveness, and expands opportunities for all NFT stakeholders. It's important to Cardano as it furthers its mission of democratization, fosters a thriving NFT ecosystem, and presents new possibilities for NFT use cases.

By creating an open-source smart contract standard and service that allows multi-marketplace NFT listings, we enable an increase in the viability of NFTs on Cardano.

This project will contribute to Cardano’s growth in several ways:

1. Open-Source Ecosystem Growth: By designing and building an open-source smart contract standard for NFT multi-marketplace listings, we are contributing a significant tool to the Cardano open-source development ecosystem. This will spur growth by providing a reusable solution that developers can build upon.
2. Interoperability: Our standard will foster greater interoperability between different marketplaces and services within the Cardano ecosystem, which is crucial for a robust, interconnected blockchain ecosystem.
3. Knowledge Sharing: The standard and the service will be fully open-sourced, with detailed documentation on how to use and integrate them. This helps to improve the overall understanding and capabilities of developers within the Cardano ecosystem.
4. Increased Opportunities: By breaking the single marketplace limitation, we open up new possibilities for NFT sellers, artists, and developers, encouraging a more vibrant and competitive marketplace ecosystem.
5. Increase Project Visibility: The multi-marketplace listing feature increases the visibility of NFTs, thereby increasing their potential for adoption and use. This increased visibility also applies to the projects themselves that choose to adopt our standard, as it enhances their offerings and user experience.

In addition the project could have a positive impact on the Cardano ecosystem in several other important ways:

• We anticipate that our project will attract more artists, developers, and sellers to Cardano because of the increased visibility and potential profits due to the multi-marketplace listing feature.
• By enabling on-chain royalties, we make Cardano a more attractive platform for creators, potentially driving more high-quality content and users to the ecosystem.
• The potential integration with other services such as staking further increases the utility and attractiveness of Cardano's NFT ecosystem.
• The open-source nature of our project contributes to Cardano's vision of a transparent, collaborative, and democratic blockchain ecosystem.

How we intend to measure impact:

Stakeholder Engagement in the Development of the Standard: Given that the development of a widely accepted standard requires consensus among stakeholders, we will measure the level of engagement from key players in the Cardano NFT marketplace. This includes the frequency and quality of their feedback during the standard development process, and their participation in discussions and meetings.

Community Feedback: We would actively solicit feedback from the community and stakeholders that engage in the standard development. This feedback, while not necessarily quantifiable, provides invaluable insights into the effectiveness of the proposed standard, its ease of use, and areas for potential improvement.

Clarity of the Proposed Standard Specifications and its Ease of Implementation: We would gather feedback from the stakeholders and the developer community on the clarity of the standard specifications and its ease of implementation. This will help us identify if our standard is well defined, easily understood, and implementable.

If successful, the standard lays the foundation for breaking the single marketplace limitation, potentially increasing competition, visibility, and opportunities for NFT stakeholders within the Cardano ecosystem. It also sets the stage for future developments like on-chain royalties and integration with other services such as staking, potentially attracting more users to Cardano.

Our project's primary output, the open-source standard for multi-marketplace listing of NFTs on Cardano, will be made accessible to all Cardano stakeholders. This includes developers, marketplace operators, artists, sellers, and the broader Cardano community.

Our plans for sharing outputs and results include:

GitHub Repository: The standard will be developed openly on GitHub, allowing anyone to follow its progress, contribute to its development, and use it once it is finalized.

Detailed Documentation: We will create comprehensive documentation for the standard, explaining its purpose, functionality, and instructions on how to implement it. The documentation will be made publicly available alongside the standard.

Community Engagement: We aim to engage the community throughout the project, not only upon completion. This includes presenting progress reports, seeking feedback, and initiating discussions in relevant forums and platforms.

Partnerships and Outreach: We will reach out to existing Cardano marketplaces, developers, and other stakeholders to co-develop the standard.

Presentation of Results: Once the project is completed, we will present our findings and the finalized standard on our GitHub page, our website and present it at a dedicated NFT Roundtable.

As for further research and development activities, the outputs from this project will serve as a foundational building block for the proposed multi-marketplace listing service. Insights gained from the development of the standard and community feedback will be invaluable in informing the design and functionality of this service. Also, the possible integration of additional features like on-chain royalties and staking services will require further exploration and development based on this standard. We envision this standard sparking a host of innovations within the Cardano NFT marketplace ecosystem.
