Abstract
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 requires very different types of memory device usage. Storage devices may be configured with a first partition for high-speed access for generating the data, while a second partition is also configured for long-term storage of the generated data. As memory devices reach their estimated end-of-life, they can be dynamically reassigned to the second partition. Likewise, some storage devices may be equipped with multiple memory arrays of different types of memory devices. One set of memory devices can be used for generation, while cheaper, write-once or few memory devices are provided for storage.
