Description: Overlay networks are structures built on top of existing networks, providing additional functionalities and enhancing connectivity and interoperability. These networks allow for the creation of additional layers of services and applications that can operate independently or in conjunction with the underlying network. In the context of distributed computing and decentralized systems, overlay networks facilitate the implementation of more efficient and scalable solutions, enabling devices to process data locally and connect to multiple networks to ensure the integrity and traceability of information. This approach not only optimizes resource usage but also improves latency and response speed, which is crucial in applications requiring real-time decision-making. Additionally, overlay networks can adapt to different protocols and standards, making them highly versatile and suitable for a variety of environments and applications, from IoT to complex data management systems.
