Storage device throttling in proof of space blockchain systems
Storage devices are configured to be utilized in a variety of blockchain related activities that rely on a proof of space consensus model. These storage devices are required to process a lot of read and write cycles on their memory devices to generate the desired proof of space consensus data. The generation and storing of this generated data require very different types of memory device usage. As these operations increase in popularity, the need to segment storage devices meant for proof of space usage and those which are not becomes more important. Storage devices may be configured to throttle these different usage types upon detecting these proof of space blockchain activities. Throttling may include reducing clock frequencies, selecting slower performing trim parameters, and programming memory devices with a reduced voltage window, among other processes. Detecting whether throttling should commence, or end can be done via a deployed machine learning classifier.
