Blockchain Subgroup Formation via Bilateral Smart Contracts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current blockchain systems lack efficient mechanisms for private resource discovery and subgroup formation, as they often require revealing sensitive information to the entire network, compromising privacy and competitive advantages.
Innovation Solution
The implementation of a method that identifies registered interests on a blockchain, accesses smart contracts, and creates temporary bilateral contracts between requestors and owners, allowing access to specific blockchain transaction information while maintaining privacy through access control rules and encryption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If blockchain systems use public ledger transparency to enable resource discovery, then accessibility and verification are improved, but privacy and competitive advantages are compromised
Solution Approach 1:
The patent segments the blockchain network into private subgroups through selective disclosure mechanisms. Instead of full transparency to all nodes, the system creates isolated communication channels between specific groups (requestors and matching owners) while maintaining overall network privacy. This segmentation allows resource discovery within subgroups without exposing information to the broader network.
Solution Approach 2:
The patent introduces smart contracts as intermediary mechanisms that mediate between requestors and resource owners. These smart contracts automatically match interests, verify access permissions, and enable secure information exchange without requiring direct disclosure of sensitive data to the entire network. The intermediary layer facilitates private resource discovery while maintaining blockchain integrity.
2Loss of information
If blockchain systems implement access control rules for private information, then privacy is improved, but system complexity increases
Solution Approach 1:
The patent implements self-service access control where smart contracts automatically evaluate requestor credentials against stored access control rules and grant or deny access without human intervention. The system autonomously manages permission verification, interest matching, and information disclosure decisions, reducing the need for complex manual access control mechanisms while maintaining strong privacy protection.
3Reliability
If blockchain systems use temporary bilateral contracts for private access, then privacy and trust are improved, but transaction processing time increases
Solution Approach 1:
The patent performs preliminary actions by pre-storing access control rules, encryption keys, and interest metadata on the blockchain before actual resource discovery operations. When a requestor initiates a search, the system can immediately query pre-indexed interests and match them with relevant resources without time-consuming real-time verification processes. This preparation enables rapid temporary contract formation while maintaining security.

AI summary
An example operation may include one or more of identifying a registered interest associated with a requestor on a blockchain, accessing a smart contract stored on the blockchain, determining a match between the registered interest and blockchain transaction information, determining the requestor associated with the registered interest has access permissions to access the blockchain transaction information based on access control rules, and creating a temporary bilateral smart contract including the requestor, and an owner of the blockchain transaction information, and the temporary bilateral smart contract provides permission for the requester to access the blockchain transaction information.
