Reticulum is an elegant engineers approach to networking. It’s a complete replacement of the network stack, it’s entirely encrypted, and can communicate and can correctly organize global-scale mesh-networks over any connection >5b/s without the need for distributed hash tables, or any resource usage besides bandwidth. This makes it far lighter than GNUnet, and friendly to low-power, low bandwidth, embedded networks and devices.
This makes it viable as a global network, as it is super cheap to interact with. And it can run on any device, including your smartphone natively.
Bandwidth is a physical resource of the natural world. Reticulum is based on the principle of creating systems that (as far as is possible for a computer program) understand the physical limits of real-world resources, and manages them responsibly and intelligently, with well-thought out algorithms.
When that is ultimately not possible any more, human beings have to step in and expand capacity or make other thoughtful decisions on how to manage the available resources. I believe this is the most efficient, holistic and human-friendly approach to creating technologies that actually help us and better our lives.
Per the docs, it is the minimum bandwidth required:
