The blockchain structure allows you to create decentralized applications that are focused on simplifying the processes and improving their performance. Such technologies can be used in any field of activity - from training programs to heavy industry. Management, a conclusion of agreements, deliveries, data registries - the entire workflow system using the blockchain can reach a qualitatively new level. This project helps you to develop in right direction. The founders of the project offer a modular system and tools for creating decentralized applications - the developers themselves will be able to customize and maintain their functionality. XTRABYTES modules are extensions of the system, dividing the possibilities of its use into several sectors. Cloud storage, smart contracts, encrypted chats, and other areas all create the basis for relevant developments. For the convenience of users, there are several popular programming languages designed to popularize the platform and simplify the transition of companies to digital technology. Communication between the modules and the XTRABYTES core is provided via the DICOM interface.
