Engineering Contradiction Analysis
1Use of energy by moving object
If conventional memory sub-systems are used for proof of space activities, then data storage is achieved, but computing power and energy consumption increase significantly
Solution Approach 1:
The patent extracts the computational burden from the host system by implementing computation accelerators within the memory sub-system itself. The controller performs proof of space challenge response generation locally using dedicated hardware acceleration, separating the computationally intensive tasks from the host processor and reducing overall system energy consumption while maintaining productivity.
Solution Approach 2:
The controller acts as an intermediary between the host system and the proof of space network. It manages cryptographic key storage, handles challenge responses, and coordinates plot generation activities, thereby reducing the computational load on the host while ensuring secure and efficient proof of space operations.
2Reliability
If cryptographic keys are managed securely for memory access and plot farming, then security is improved, but system complexity increases
Solution Approach 1:
The patent merges cryptographic key management functionality directly into the memory sub-system controller. The controller integrates secure key storage, cryptographic operations, and plot pool management in a unified architecture, reducing system complexity by eliminating separate key management hardware while maintaining high security standards through hardware-based protection.
Solution Approach 2:
The memory sub-system performs self-service cryptographic operations autonomously. The controller generates, stores, and manages cryptographic keys internally, and automatically handles proof of space challenge responses without requiring external intervention, thereby simplifying the overall system architecture while ensuring secure operations.
3Ease of operation
If computation accelerators are implemented in memory sub-system, then computational burden on host is reduced, but device complexity increases
Solution Approach 1:
The controller is designed with multi-functionality, serving both as a memory management unit and a computation accelerator for proof of space operations. It handles traditional memory control tasks while simultaneously performing cryptographic operations, challenge response generation, and plot management, thereby reducing host burden without requiring entirely separate dedicated hardware.
Solution Approach 2:
The patent replaces software-based cryptographic operations on the host system with hardware-based computation accelerators embedded in the memory sub-system. This substitution of mechanical/computational mechanisms from software execution to dedicated hardware circuits reduces the computational burden on the host while the added hardware complexity is confined to the memory sub-system where it performs specialized functions efficiently.

AI summary
A security server storing a plurality of cryptographic keys to support device authentication, access control and proof of space plot farming. The cryptographic keys can include a first cryptographic key representative of an identity of a memory device, a second cryptographic key representative of a privilege to access a memory region in the memory device, and a third cryptographic key representative of a pool of proof of space plots. The security server can sign blocks in a blockchain created via plots in the pool, sign commands to access the memory region, and secure transfer of the second and/or third cryptographic key to the computer operated by an owner of the memory device.
