Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current blockchain security mechanisms, such as Proof of Work and Proof of Stake, face limitations including high energy consumption, vulnerability to attacks, and reliance on trust relationships among terrestrial entities, which can compromise data integrity and scalability.
Innovation Solution
Deploying data processing nodes to physically inaccessible locations, such as spacecraft, to generate and manage verification signing key pairs, ensuring secure key generation and transmission, thereby reducing the need for energy-intensive computations and trust in terrestrial entities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Proof of Work is used to secure the most recent block in blockchain, then data integrity is improved, but energy consumption increases significantly
Solution Approach 1:
The patent extracts the key generation function from terrestrial blockchain nodes and relocates it to a physically inaccessible platform (such as a spacecraft). This separation removes the need for energy-intensive Proof of Work computations on Earth-based systems while maintaining cryptographic security. The inaccessible platform generates verification signing keys that are then distributed to terrestrial nodes, eliminating the contradiction between data integrity and energy consumption.
Solution Approach 2:
The patent introduces a new dimension of physical inaccessibility (space-based or remotely located platform) to the blockchain architecture. By moving the trusted key generation function to this new dimensional space, the system achieves both data integrity and reduced energy consumption, as the inaccessible platform requires no computational proof of work while its physical location prevents tampering.
2Use of energy by moving object
If Proof of Stake is used to secure the most recent block in blockchain, then energy consumption is reduced, but vulnerability to attacks and trust relationships among terrestrial entities increase
Solution Approach 1:
The patent introduces a physically inaccessible platform as an intermediary between terrestrial blockchain participants and the trusted key generation function. This intermediary eliminates the need for trust relationships among terrestrial entities (solving the Proof of Stake vulnerability) while maintaining low energy consumption. The inaccessible platform acts as a neutral, unassailable authority that generates verification signing keys without requiring terrestrial trust or energy-intensive validation.
3Ease of operation
If terrestrial entities are used to generate and manage verification signing keys, then ease of operation is improved, but trust relationships and attack vulnerabilities increase
Solution Approach 1:
The patent extracts the key generation function from terrestrial entities and relocates it to a physically inaccessible platform. This extraction maintains ease of operation for key distribution (terrestrial nodes still receive and use keys normally) while eliminating the trust vulnerability by removing terrestrial entities from the key generation process. The inaccessible platform becomes the sole trusted source of verification signing keys.

AI summary
Described are techniques for securing a most recent block in a data structure such as a blockchain. Techniques include configuring a data processing node that is deployable to a physical location, with a module that generates a verification signing key (VSK) pair, the VSK pair including a private VSK key that is known only to the data processing node, and a public VSK key, receiving by the data processing node, an indication of the deployment to the physical location, generating in response to the indication, by the data processing node the verification signing key (VSK) pair, and transmitting from the data processing node the public VSK key to one or more electronic devices. These techniques assure to a high degree that the generated private key remains unknown and thus can be used to secure the most recent block that is added to a data structure such as a blockchain.
