We wanted to build a system that allows us to honor our deceased loved ones by creating virtual memorials in cemeteries that are also embedded on the Solana blockchain, creating an immutable legacy of life.

What it does

Family and friends can use their mobile AR devices to access the AR content, which could include photographs, videos, and written tributes and memories of a life well lived. Additionally, the AR system could include features such as virtual flowers and candles that visitors could leave at the virtual memorials. GPS coordinates of the deceased's final resting place and legacy information about their lives are written to Solana to create a permanent digital memorial for those who came before us. We incorporate the use of Solana blockchain technology into the Augmented Reality system for virtual memorials to provide an additional layer of security and permanence to the digital representations of loved ones. By storing the digital information on the blockchain, it would be immutable and resistant to tampering or deletion, ensuring that the virtual memorials will remain accessible for future generations. In digital legacy tracking, Self-sovereign identity (SSI) concepts can be implemented, where the individual would have full control over their own digital identity and assets, and being able to share it with others on their own terms, ensuring that the assets are passed on to their desired heirs or beneficiaries.

Overall, this system would provide a new way for people to remember and honor their loved ones in a meaningful and interactive way.

How we built it

We built this project with a lot of dedication and reverence. We used a full pipeline of creative production tools including Shapes XR for prototyping, Unity for development, Cinema 4D for modeling, DAll-E 2 AI, and a host of other programs. We used Unity Engine, Solana's Unity SDK, ShapesXR, Cinema4D, Adobe, Dall-E 2, Oculus Quest Pro, and Google's new Geolocation API.

Challenges we ran into

  1. Slow WiFi speed
  2. Unity errors and crashing
  3. Integrating various components was difficult and a real blocker
  4. Limitation of the free version apps we used

Accomplishments that we're proud of

We are proud of coming together as a team and creating something meaningful, beautiful, and technically challenging. We created a system that could be used to not only archive the most beautiful moments of a person's life, but what could eventually be the beginning of Self-sovereign identity (SSI). Our system also allows us to write real time GPS coordinates to the blockchain, opening up a host of new possibilities.

What we learned

We learned some pretty exciting new technologies and became familiar with the new Solana SDK and Google's Geospatial API.

What's next for Memento Mori

We plan to develop this project further and really polish the technology that we've used to put it together. We believe this could be a commercially viable opportunity.

Road map: Going to the future, we plan to: Incorporate greater accessibility by creating WebAR/ OpenAR version of the application. Write a white paper explaining our process. Create white label versions of the app for communities. Expand the concepts and ideas behind our project to splinter out into new useful modalities and applications.
