Blockchain Transaction Verification Through Subscription Nodes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In current blockchain hierarchical consensus systems, transactions that are not expected to be disclosed in plaintext to third parties are recorded on a blockchain that forbids external access, making verification and query difficult for the local consensus network.
Innovation Solution
The target consensus network performs upload verification on transactions and transmits transaction result data to a subscription node, allowing the local consensus network to acquire the results without accessing the blockchain directly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the target blockchain forbids external access to ensure security, then transaction data privacy is improved, but verification and query capability deteriorates
Solution Approach 1:
The patent introduces a subscription node as an intermediary component between the local consensus network and the target blockchain. This subscription node subscribes to block information from the target blockchain and relays it to the local consensus network, enabling verification without direct external access to the blocked blockchain. The intermediary resolves the contradiction by providing a controlled information channel that maintains security while enabling necessary verification functions.
2Object-affected harmful factors
If the target blockchain forbids external access to maintain security, then data confidentiality is improved, but upload result interaction deteriorates
Solution Approach 1:
The subscription node serves as a mediator that enables upload result interaction between the local consensus network and target blockchain without requiring direct access to the blocked chain. The subscription node receives block information from the target blockchain and forwards it to subscribed nodes in the local consensus network, facilitating trusted interaction while maintaining data confidentiality.
Solution Approach 2:
The patent shifts the interaction dimension from direct blockchain access (vertical dimension) to a subscription-based information relay mechanism (horizontal dimension). Instead of the local consensus network directly querying the target blockchain, interactions occur through the subscription node layer, enabling upload result verification without compromising the blocked nature of the target blockchain.
3Reliability
If transactions are recorded on a blocked blockchain to prevent third-party disclosure, then security is improved, but accessibility for verification deteriorates
Solution Approach 1:
The subscription node acts as a trusted intermediary that bridges the local consensus network and the blocked target blockchain. It subscribes to relevant block information from the target blockchain and relays it to local nodes, enabling verification and query operations without requiring direct access to the security-blocked chain. This maintains both security and accessibility through the intermediary layer.

AI summary
A method for processing a transaction of a blockchain includes acquiring an added first target block from first blocks of a first blockchain that forbids external access to a target consensus network, wherein the first target block is generated by the target consensus network and is configured for recording a first transaction of a target type from a local consensus network; acquiring a first target transaction and a first block header from the first target block; acquiring first verification information corresponding to the first target transaction; performing upload verification on the first target transaction based on the first target transaction, the first verification information, and the first block header; acquiring transaction result data of the first target transaction if the upload verification succeeds; and transmitting the transaction result data to a subscription node for the local consensus network to acquire the transaction result data from the subscription node.
