Which Hyperledger project is focused on mobile application development?

Iroha is specifically designed with mobile application development in mind, catering particularly to the needs of mobile users and developers. Its architecture incorporates a straightforward API that enables easy integration into mobile applications, allowing developers to leverage blockchain technology without having to navigate through the complexities often present in other blockchain frameworks.

Iroha emphasizes usability and a straightforward approach, making it suitable for mobile environments where simplicity and efficiency are paramount. This focus on mobile allows developers to create applications that can leverage the security features of blockchain while being accessible on mobile platforms.

In contrast, the other projects have different primary focuses. Fabric is oriented towards enterprise-grade applications and modular architecture, while Burrow is designed with smart contracts in mind but doesn’t cater specifically to mobile. Caliper is a benchmarking tool, useful for testing performance but not directly tied to mobile app development.
