# Why Chromia?
XOOB utilizes RELL technology from Chromia for data processing and ensuring data security. RELL offers several advantages that contribute to creating reliable, secure,and high-performance applications
### **Advantages of Using RELL from Chromia for XOOB:**
* **Ensuring Application Security and Reliability**
RELL from Chromia is equipped with built-in access control and management mechanisms, ensuring the security and reliability of all operations. With protection against overflows and mandatory authorization checks, risks are minimized, and a high level of security for data and transactions is maintained.
* **Implementing Complex Interaction Scenarios**
RELL efficiently implements complex interaction and information exchange scenarios with minimal costs. Thanks to its conciseness and expressiveness, RELL significantly reduces the amount of code needed for complex operations, enhancing developer productivity and reducing development and maintenance costs.
* **Effective Data and Resource Management**
RELL's relational model provides efficient data and resource management. It allows for the execution of complex queries and handling large volumes of data directly on the blockchain, ensuring high throughput and rapid transaction processing. This is particularly important for XOOB, which requires intensive data processing and high system performance.
