Middleware Layer

The middleware layer is an interface that reads and records the data stored on the storage layer. dKargo’s diverse services can be accessed on the storage layer through the middleware layer. Participants can use various tools that the middleware layer provides to easily connect their services to the dKargo platform.

dKargo platform can only succeed when the participants of the current logistics network can easily join the platform. dKargo will provide SDK (Software Development Kit) to many service providers currently in operation, to help them connect their services to dKargo’s platform. SDK will be designed to be compatible with existing programming techniques. This will help developers who aren’t familiar with blockchain technology to easily participate in the platform.

The middleware layer will also provide extra data on specific information for logistics services such as the standard specification of freight information, regulations in each country, and standards for payment. This is to help participants gain easier access to data they need to provide their services. It will help existing service players to enter the platform.

dKargo suggests making standards for ordering, storing, transporting and making payment through the dKargo Request for Comments (DKRC) document. dKargo will form a steering committee with partners to discuss and make decisions on these matters. This process will meet the standards for data and API (Application Program Interface) which will allow any partners within the ecosystem to participate in making any types of services, whether it be in the middleware, service layer or API. It will encourage partners to participate in creating the DKRC standards with the programming language that fits their existing system or commonly used by their developers. dKargo will provide at least more than one method of implementing the reference for each sector. Partners and individuals can use the reference to create APIs with more functions and new services while following the standards.
