Storage device optimizations 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 requires very different types of memory device usage. Storage devices may be configured to optimize these different usage types upon detecting these proof of space blockchain activities. These optimizations can include suspending one or more background or other garbage collection activities. Additional optimizations can further include configuring partitions or namespaces to comprise single-level-cell majority or single-level-cell only memory devices to increase writing speeds. Further optimizations can include interleaving or extending the length of error correction codes. These optimizations, while not suitable for general use, are suitable for proof of space blockchain activities.
