Blockchain Node Multi-Party Authorization for Digital Asset Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Centralized management of digital assets is insecure and prone to fraud, as it can be easily compromised, leading to impersonation and unauthorized transactions.
Innovation Solution
A blockchain-based method where a block chain node sends authorization requests to multiple electronic devices, requiring a proportion of them to authorize digital asset processing, ensuring multi-party authorization and improving security by using decentralized keys for encryption and decryption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If centralized management is used for digital asset transactions, then management efficiency is improved, but security deteriorates due to vulnerability to fraud and impersonation
Solution Approach 1:
The patent segments the centralized management system into a distributed blockchain network where multiple nodes collectively manage digital assets. Each node operates independently with equal rights to verify and record transactions, eliminating the single point of failure in centralized systems while maintaining efficient transaction processing through consensus mechanisms.
Solution Approach 2:
The patent introduces cryptographic algorithms and consensus mechanisms as intermediaries between transaction parties and the blockchain network. These intermediaries enable secure, trustless transactions by verifying identities and validating transactions without requiring a centralized authority, thus improving security while maintaining efficiency.
2Reliability
If multi-party authorization is implemented for digital asset processing, then security is improved, but processing time increases due to multiple authorization requests
Solution Approach 1:
The patent implements preliminary action by pre-distributing authorization keys to multiple nodes before transactions occur. When a transaction requires multi-party authorization, the system can quickly verify pre-established key relationships and authorization thresholds, significantly reducing the time required compared to real-time key generation and distribution.
Solution Approach 2:
The patent merges multiple authorization requests into a single consensus verification process. Instead of sequentially processing each authorization request separately, the blockchain network combines them into one atomic operation where all required parties' authorizations are verified simultaneously through the consensus mechanism, reducing total processing time while maintaining security.

AI summary
The present disclosure discloses a method and a device for information processing. The method includes the following. A block chain node receives a digital asset processing request, where the digital asset processing request is used for requesting authority to process the digital assets. Upon receiving the digital asset processing request, the block chain node sends an authorization request to each of M electronic devices, where the authorization request is used for requesting authorization to process the digital assets. The block chain node determines that each of at least N electronic devices of the M electronic devices provides the authorization to process the digital assets, where M is greater than or equal to N. The block chain node determines to obtain the authority to process the digital assets.
