Holopolis is a community-driven project that creates a library of 3D models of ancient cities. These models can be explored through augmented reality (AR) and virtual reality (VR) applications. The project uses the decentralized infrastructure of Solana Blockchain to provide an open-source 3D model database that is accessible to registered users. Holopolis introduces a new Non-Fungible Tokens (NFTs) concept as city collections. NFTs are unique digital assets that cannot be replaced with another identical asset. They are stored on the blockchain, which makes them secure and tamper-proof.
Holopolis is a breakthrough project that combines the latest augmented and virtual reality (AR/VR) technologies with a blockchain-based infrastructure to create an open-source 3D model database of ancient cities. The project aims to democratize access to these models for personal use or academic research while creating new tourism and education opportunities.
Holopolis introduces a new Non-Fungible Tokens (NFTs) concept as city collections. Each ancient city will have its own NFT collection that will be offered to the public through a limited release. NFT holders will not only own a unique digital asset but also have the opportunity to earn a percentage from the in-app purchases of city collections from mobile stores. The remaining funds will be used to build the IPFS library, AR and VR apps, and marketing.
The initial collection of Holopolis is the Ephesus Collection, a carefully crafted 3D model of the ancient city of Ephesus. The collection consists of 15 buildings reconstructed faithfully by architects and archeologists specializing in Greco-Roman architecture and art history. These buildings will be added to the Holopolis app, allowing users to explore the ancient city in its original form through augmented reality. NFTs in the Ephesus Collection will have a limited total supply of 3000, with each tier varying in rarity. Holders of higher-tiered NFTs will have the potential to earn more royalties from the in-app purchases of City Collections, incentivizing users to collect and stake higher-rarity NFTs.
| Tier | Rarity | Distribution | Total |
|---|---|---|---|
| Iron | Common | 50% | 1500 |
| Bronze | Uncommon | 30% | 900 |
| Silver | Rare | 15% | 450 |
| Gold | Very Rare | 5% | 150 |
The Holopolis app has three main features: the Crowd Sourcing Tool, the AR Lens, and the VR Time Travel Experience.
The Crowd Sourcing Tool is the backbone of Holopolis, allowing individual users to contribute to the open-source model database. Users can take photos of ancient sites they travel to using the crowd-sourcing lens feature of Holopolis. AI-assisted instructions guide users in taking the right photos to create 3D models of buildings or monuments using photogrammetry and other digital reconstruction methods. All models will be stored on the Solana blockchain and accessible to registered Holopolis users.
The AR Lens feature within the Holopolis app completes missing parts of ancient city structures, monuments, and sculptures. New cities and buildings will be added to the AR Lens with each NFT Collection. This feature is particularly interesting for travelers or residents of cities where the ancient cities are located in.
The Experience is a virtual journey through a reconstructed city of old, with animated NPCs and recreated urban settings based on the site's historical studies and archeological findings. The experience recreates an authentic and immersive environment for users to explore history from a first-person point of view.
