Blockchain Interoperability via Membership Credential Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Distributed ledger technologies (DLTs) face challenges in cohesive sharing, synchronization, and transferring of information due to unique protocols and design considerations, especially when different DLTs are involved, leading to inefficiencies and security threats from malicious agents.
Innovation Solution
The implementation of a membership-based cryptological blockchain interoperability system, where a membership blockchain stores identity and credential information across multiple nodes, allowing DLT networks to establish trust and validate certifications without a gateway node, enabling secure and efficient information exchange between DLT networks with different rules and technologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a gateway node is used to enable information exchange between DLT networks, then interoperability is achieved, but system complexity and potential security threats increase
Solution Approach 1:
The patent extracts the identity verification and credential validation functions from the gateway node concept, implementing them instead through direct cryptographic verification between DLT networks using stored identity information and credentials, thereby eliminating the need for a complex gateway infrastructure while maintaining interoperability
Solution Approach 2:
The patent uses cryptographic credentials and identity proofs as intermediaries that enable trust establishment between DLT networks without requiring a physical or architectural gateway node, allowing direct peer-to-peer verification while maintaining system simplicity
2Productivity
If DLT networks with different protocols share information directly, then efficiency is improved, but security risks from malicious agents increase
Solution Approach 1:
The patent performs preliminary identity verification and credential validation before information exchange occurs, storing and verifying identity information and credentials in advance, so that when data sharing happens directly between DLT networks, security is already established without requiring slow verification processes during the actual exchange
Solution Approach 2:
The patent implements cryptographic verification feedback mechanisms where receiving networks can verify the authenticity and validity of credentials from sending networks, creating a feedback loop that confirms security compliance while enabling efficient direct information exchange
3Speed
If identity information is stored centrally for verification, then validation speed is improved, but system vulnerability to attacks increases
Solution Approach 1:
The patent segments the identity verification system into distributed cryptographic credentials stored across multiple DLT networks rather than a single central repository, allowing fast local verification while eliminating the single point of failure vulnerability associated with centralized storage
Solution Approach 2:
The patent uses cryptographic copies and hashes of identity information that can be verified without exposing the actual sensitive data, enabling fast validation through credential verification while protecting the original identity information from centralized storage vulnerabilities

AI summary
Systems and methods for membership-based cryptologic blockchain interoperability are provided. A receiver distributed ledger technology (DLT) network may include a data receiver node and a receiver validator node. The receiver validator node may receive a certification of token data stored on a furnisher blockchain. The certification may be signed by a plurality of furnisher validator nodes of a furnisher DLT network. To validate the certification, the receiver validator may obtain a furnisher credentials stored on a membership blockchain. The receiver validator node may perform the validation based on the furnisher credentials. The receiver validator node may digitally sign a validation of the certification. The receiver node of the receiver DLT network may commit the token data to a receiver blockchain in response to validation of the certification.
