Blockchain Interoperability via Directory and Identity Service Nodes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Heterogeneous blockchain networks are isolated due to different communication protocols and formatting standards, leading to inconsistencies in data retrieval and potential breakdown of consensus when interacting with external sources.
Innovation Solution
A system and method that enables communication between blockchains by using a directory service node to identify receiving blockchains through machine learning algorithms and an identity service node to verify trust certificates, allowing for end-to-end payment flows despite differing messaging formats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If blockchain networks use different communication protocols and formatting standards, then each blockchain can operate independently with its own characteristics, but the blockchains become isolated and unable to communicate with each other
Solution Approach 1:
The patent introduces a gateway node as an intermediary component that sits between heterogeneous blockchain networks. This gateway node translates messages from one blockchain's protocol format into another blockchain's protocol format, enabling communication between isolated networks without requiring them to modify their own core protocols. The gateway acts as a mediator that resolves the format incompatibility issue while preserving the independence of each blockchain network.
2Adaptability or versatility
If each node in a blockchain network retrieves information from an external source individually, then the network can access external data, but there is no guarantee that each node will receive the same answer, breaking consensus
Solution Approach 1:
The patent introduces a directory service as an intermediary that all nodes must query before accessing external sources. The directory service maintains a centralized record of valid external data sources and returns consistent responses to all node queries. This ensures that every node retrieves the same external information through a unified interface, preserving consensus validity while still enabling external data access across the distributed network.
3Reliability
If blockchain networks establish trusted connections through identity service nodes and trust certificates, then communication reliability is improved, but system complexity increases
Solution Approach 1:
The patent introduces an identity service node as an intermediary that handles all trust verification operations. Instead of each node performing complex trust verification independently, nodes simply query the identity service node, which returns pre-validated trust information. This centralized approach maintains high reliability for connection trustworthiness while significantly reducing the complexity burden on individual nodes, as trust verification is handled as a simple query-response operation.
Data Source
AI summary
A system for enabling communication between blockchains on heterogeneous blockchain networks. The system can include a sending blockchain network comprised of a sending blockchain that includes a plurality of blocks, each block including a block header and one or more transaction values associated with an identification request transmitted by the sending blockchain. The system can include a directory service node configured to receive the identification request from the sending blockchain, and identify a receiving blockchain, which forms part of a receiving blockchain network. The system can include an identity service node configured to receive a trust request from the directory service node to determine whether a valid trust certificate is available for the receiving blockchain, and enable communication between the sending blockchain and the receiving blockchain, when the valid trust certificate is determined to be available.
