Decentralized Blockchain Key Segmentation and Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional software solutions fail to securely generate and retrieve blockchain keys, leading to insecure data access and potential cyber-attacks, as users often rely on third parties or internal databases that can be compromised.
Innovation Solution
A system and method for dynamic encryption and decryption of blockchain keys, where a server generates and divides a blockchain key into segments, encrypts them, and distributes them across network nodes, allowing secure retrieval and storage using cryptographic hashes and authentication methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If blockchain keys are stored in an internal database for easy retrieval, then ease of operation is improved, but security is worsened because the database may be subjected to cyber-attacks and keys may be accessed by hostile third parties
Solution Approach 1:
The patent divides the blockchain key into multiple key segments and distributes them across different network nodes instead of storing the complete key in a single internal database. This segmentation ensures that no single point of failure exists, and an attacker would need to compromise multiple nodes to retrieve the complete key, thereby maintaining both ease of retrieval through automated distribution and enhanced security through decentralized storage
2Ease of operation
If a third party is used to recreate lost blockchain keys, then ease of operation is improved, but security is worsened because the third party gains possession of the user's private key or other sensitive data
Solution Approach 1:
The patent segments the blockchain key into multiple parts and distributes them across network nodes, eliminating the need for third-party intervention in key recovery. Users can retrieve their keys through the decentralized network without exposing their private data to external parties, thus maintaining operational convenience while preventing data exposure to third parties
Solution Approach 2:
The system enables users to recover their own blockchain keys through the decentralized network without requiring third-party assistance. The automated key retrieval mechanism allows users to access their segmented keys through the network nodes, making the system self-service oriented and eliminating security risks associated with third-party key management
3Reliability
If blockchain keys are distributed across multiple network nodes, then security is improved, but device complexity is worsened
Solution Approach 1:
The patent divides the blockchain key into multiple segments and distributes them across network nodes, which inherently increases system complexity. However, this segmentation is necessary to achieve the desired security level, where no single node holds the complete key, and an attacker would need to compromise multiple nodes simultaneously to gain access
Solution Approach 2:
The patent employs a universal key management system that can operate across different blockchain networks and platforms. The segmented key distribution mechanism and automated retrieval process are designed to be protocol-agnostic, allowing the same system architecture to serve multiple functions and reducing the perceived complexity through standardization

AI summary
Methods and systems disclosed herein generate a secure blockchain key for a user by generating a blockchain key comprising a string of alphanumerical and/or character values; generating one or more key segments by dividing the key string in to a number of sub-strings based on a first encryption method; encrypting each sub-string based on a second encryption method; determining a latest valid blockchain associated with the user; identifying a group of network nodes associated with the latest valid blockchain; selecting a number of network nodes from the identified group of network nodes; and instructing the selected network nodes to store the encrypted key segments.
