👉 Witness computing is a distributed computing paradigm where individual devices, such as smartphones, computers, or IoT sensors, act as temporary data processors and storage units to support larger computational tasks. In a witness computing setup, these devices, referred to as witnesses, are responsible for performing computations or verifying data integrity without necessarily executing the full computational task themselves. Instead, they compute specific "witnesses" to evidence or validate information, which are then aggregated by a central authority or other witnesses to ensure consistency and accuracy. This approach is particularly useful in scenarios requiring real-time data processing, such as fraud detection, environmental monitoring, or secure voting systems, as it leverages the ubiquity and computational capabilities of everyday devices while maintaining robust security and efficiency.
