The integration layer refers to the component or framework that connects a blockchain network with external systems, applications, and services. Its primary function is to facilitate communication and data exchange between the blockchain and other environments, such as traditional financial systems, or decentralized applications.This layer can include APIs, middleware, and protocols that allow users to interact with blockchain features, like executing smart contracts, managing transactions, or accessing data. By acting as a bridge, the integration layer enhances usability, making it easier for developers to build applications that leverage blockchain technology.Moreover, a robust integration layer can help improve scalability and interoperability between different blockchains, allowing them to share data and functionality. Through these connections, users and businesses gain access to a broader range of services and tools that can enhance their operations or user experience. Ultimately, the integration layer plays a crucial role in expanding the reach and capabilities of blockchain technology beyond its native environment.
