# Use Cases

## **DINO Hub**

[**DINO Hub**](https://dinohub.io/) is the center for **Data and AI with Marketplaces** and **crowd-sourcing-based annotation services**. **DINO Hub** is a Web3-inspired platform that aims to provide end-users and businesses tools and services to sell, buy, request, and stake data and AI APIs in a decentralized environment: automated validation, transparent transactions, and secure payment.

**DINO Hub** requires storing a large amount of data including files, encrypting data by default, authentication-based data sharing, and preventing data breaches or unwanted destruction.

#### **EUENO's solutions:**

* All data are encrypted
* Scalable storage capacity for files
* Decentralized storage
* High resilience
* Authentication before sharing

## **Oraichain Labs US**&#x20;

[**Oraichain Labs US** ***(“OLUS”)***](https://orai.us/) is **an independent Fin-tech startup founded in the United States** with the vision to modernize and broaden access to capital markets by becoming a market leader in asset tokenization.

**OLUS** requires storing a large amount of metadata associated with each ERC-721 contract of a physical asset. The metadata is encrypted and access to the metadata is strictly permissive. The metadata can be updated, however, the records of revision must be stored for future reference. Data breaches or unwanted destruction of metadata must not happen.

#### **EUENO's solutions:**

* Big data storage
* Permissive access control
* High resilience
* Dynamic replication

## **Kawaiiverse**

Evolving from Kawaii Islands, Kawaiiverse is an Anime Metaverse where everyone can play, create, connect and earn. Running as a subnetwork on the Oraichain Mainnet, Kawaiiverse aims to be the hub for all independent creators and developers to join and create to earn with ready-to-use tools.

To foster the creation of artworks and content, Kawaiiverse requires big data storage and access-based payment through authentication for both creators and users.

#### **EUENO's solutions:**

* End-to-end data encryption
* Dynamic replication
* Authentication for access control
