Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the memory sub-system uses external host system resources to participate in proof of space activities, then the proof of space tasks can be performed, but the memory sub-system cannot operate autonomously and requires external host supervision
Solution Approach 1:
The patent combines the host system functions directly into the memory sub-system by integrating a processor and proof of space manager within the memory device itself. This merging eliminates the need for external host supervision while maintaining all necessary proof of space functionalities, thereby achieving autonomous operation without proportionally increasing overall system complexity.
Solution Approach 2:
The memory sub-system is designed to perform multiple functions: it serves as both a storage device and an autonomous participant in proof of space activities. The integrated processor and proof of space manager enable the device to independently generate commands, participate in cryptographic networks, and manage its own storage resources, making it a universal component that eliminates the need for separate host system involvement.
2Use of energy by moving object
If the memory sub-system operates with external host supervision, then power consumption can be optimized when host is active, but the memory sub-system cannot operate when host is in low power modes
Solution Approach 1:
The memory sub-system is equipped with an integrated processor and proof of space manager that enable it to serve itself autonomously. The device can independently detect network connections, generate proof of space commands, and participate in cryptographic activities without requiring external host supervision, allowing it to operate flexibly across all power modes including when the host is in low power states.
3Productivity
If the memory sub-system autonomously detects network connections and generates commands, then external host resources are freed, but the internal processing burden increases
Solution Approach 1:
The patent integrates the processing functions previously performed by the external host directly into the memory sub-system. The processor and proof of space manager work together as a unified internal system that handles network detection, command generation, and cryptographic operations, thereby freeing external host resources while managing internal processing complexity through integrated design.

AI summary
An apparatus with a solid state drive (SSD) having an internal host to control proof of space activities. The SSD has a host interface configured to receive at least read commands and write commands from an external host system. The SSD has memory cells formed on at least one integrated circuit die, and a processing device configured to control executions of the read commands to retrieve data from the memory cells and executions the write commands to store data into the memory cells. The internal host operable is to generate, independent of the external host system, commands related to proof of space, such as plot generation, and plot farming.
