Cardinal – Putting Cardano DePIN on the map

In the rapidly evolving world of blockchain technology, the Cardano ecosystem stands out for its innovative approach to decentralization and infrastructure development. However, as numerous decentralized physical infrastructure network (DePIN) projects emerge, a significant challenge has surfaced: the lack of a unified platform to visualize and understand the geographic distribution of these projects. This gap not only hinders awareness and strategic planning but also limits the potential for synergies, community engagement, and investment opportunities within the Cardano network.

Cardinal aims to create a dynamic, interactive map that aggregates geolocation data from various Cardano DePIN projects, such as World Mobile Token (WMT) and Iagon (IAG). By gathering this data into a user-friendly visual format, Cardinal seeks to revolutionize how stakeholders access, interpret, and utilize information about the decentralized infrastructure spread across the globe.

As Cardano continues to expand, the ability to visualize the network’s physical infrastructure in real-time will be crucial for enhancing collaboration, driving informed decision-making, and supporting the ecosystem’s growth and scalability. In this article, we will explore how Cardinal plans to achieve these goals, the unique features of its platform, and the transformative impact it aims to have on the Cardano community.

Q&A with the team

Q1: Why did you decide to embark on this project? Why is DePIN important to you?

A1: I decided to embark on this project because I thought it would be interesting to plot the geo-location data of Cardano-related DePIN projects. Initially, I started experimenting with WMT’s and Iagon’s API location data of nodes and merged this information. After sharing these maps on social media, I received an overwhelmingly positive response. Although the process was manual at first, I brought in my teammate who was keen on automating it and developing an app around this concept. Together, we began building what is now the early version of Cardinal.
DePIN excites me because it represents a significant advancement in blockchain utility. It decentralizes data and network management, shifting control away from centralized entities to a more secure, community-based infrastructure. Today, centralized entities often misuse our data without our consent. DePIN empowers us to reclaim control over our data, ensuring it is used in ways we approve.

Q2: We only have two DePIN projects on Cardano which you already integrated into the proof-of-concept. What else is left to do that you need to get funding?

A2: We aim to integrate the registered relays of Cardano nodes into the platform. Additionally, as new projects become available, such as NuNet, we plan to incorporate them as well. Improving the user experience is another priority, particularly through enhanced visualizations and exploring different mapping solutions. We also intend to add more statistics to the site to allow for deeper data analysis. These enhancements will help us provide a more comprehensive and user-friendly platform, justifying the need for additional funding.

Q3: Will Cardinal support new DePIN projects in the future, should they arise from the ecosystem?

A3: Yes, we plan to incorporate all Cardano-related DePIN projects within Cardinal. We have already initiated discussions with NuNet about possibly integrating their nodes into Cardinal. Additionally, we are brainstorming other ideas, such as aggregating Cardano Beam data, which involves placing GPS-based assets on the Cardano blockchain. Our goal is to continuously expand and adapt Cardinal to support new projects as they emerge in the ecosystem.

Q4: Will Cardinal also show World Mobile EarthNodes when they are operational?

A4: If World Mobile makes the geo-location data of EarthNodes publicly available, we would be eager to integrate it into Cardinal. However, it is essential to find the right balance. For instance, knowing the exact GPS location is necessary for using AirNodes services, but for Iagon, revealing the exact location of the device could pose a security risk. Consequently, Iagon only publishes the city and country. Our approach will be to respect the level of detail each project deems appropriate for public sharing while ensuring the utility and security of the data.

Q5: What do you envision for the future of this project in case it gets funded?

A5: We envision Cardinal becoming the central hub for viewing all Cardano DePIN geo-location data and providing insightful statistics around it. Our goal is to create a comprehensive platform that offers valuable information and analytics, making it an indispensable resource for the Cardano community and DePIN projects.
