Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If proof of space plots are generated and stored in conventional memory sub-systems, then storage capacity is utilized, but energy consumption and host system resource usage increase
Solution Approach 1:
The memory sub-system performs autonomous proof of space plot generation, management, and peer-to-peer transfer operations without requiring host system intervention. The controller independently handles cryptographic operations, plot file creation, and network communication, allowing the storage device to serve its own computational and networking needs while utilizing unused storage capacity
Solution Approach 2:
The patent extracts proof of space activities from the host system and relocates them to the memory sub-system itself. By separating plot generation, storage management, and transfer operations from the host CPU and memory resources, the system utilizes idle storage capacity and integrated controller resources without burdening the host system's energy-constrained components
2Speed
If proof of space plots are transferred through host system, then data transfer is enabled, but host system resources and bandwidth are consumed
Solution Approach 1:
The memory sub-system's integrated controller acts as an intermediary that directly manages peer-to-peer plot transfers between storage devices. The controller establishes and maintains network connections, handles plot file transmission protocols, and manages bandwidth allocation independently, eliminating the need for host system software agents and reducing complexity in the host's resource management stack
Solution Approach 2:
The patent segments the data transfer function into independent components: the memory sub-system's controller handles network communication and plot file transmission directly to peer devices. This segmentation separates storage management and network communication tasks from the host system, allowing parallel operation and reducing contention for host system resources and bandwidth
3Ease of operation
If autonomous operation is implemented in memory sub-system, then host system burden is reduced, but control and management complexity increases
Solution Approach 1:
The memory sub-system controller is designed with multi-functionality, integrating storage management, cryptographic processing, network communication, and plot file generation capabilities within a single control unit. This universal controller handles all autonomous operations internally, presenting a simplified interface to the host system while managing complex internal coordination between different functional components
4Quantity of substance
If proof of space activities are performed, then storage space is utilized, but computing resources and energy are consumed
Solution Approach 1:
The memory sub-system's integrated controller performs cryptographic hashing and proof of space calculations using its own processing resources rather than relying on the host system's CPU. This self-service approach utilizes idle controller computing capacity to generate and verify plots, converting otherwise wasted computational resources into productive proof of space operations while maintaining storage utilization
