👉 Witness computing, also known as distributed or collaborative computing, is a model where multiple devices, such as smartphones, laptops, or sensors, work together to solve complex computational problems. Instead of relying on a single powerful device, the system distributes tasks across these connected devices, leveraging their collective processing power and resources. This approach enhances efficiency, scalability, and resilience, as tasks can be offloaded to nearby devices when local resources are limited. Witness computing is particularly useful for applications requiring real-time data processing, such as environmental monitoring, traffic management, and disaster response, where the combined computational capabilities of numerous devices can provide more accurate and timely insights than any single device could achieve alone.
