Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information transmission systems rely heavily on third-party services, leading to potential information leakage and security risks, particularly for sensitive data and digital assets, due to the 'single point of failure' vulnerability.
Innovation Solution
A blockchain-based information transmission method utilizing a point-to-point transmission network with smart contracts, asymmetric encryption, and token distribution to ensure secure and efficient transfer of sensitive data, with blockchain serving as a trusted bulletin board for recording transmission status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If traditional centralized storage systems are used, then data access speed is improved, but system security and reliability deteriorate due to single points of failure
Solution Approach 1:
The patent segments data into multiple blocks and distributes them across different nodes in a blockchain network. Each node stores copies of data blocks, eliminating centralized storage. This segmentation allows parallel access from multiple nodes simultaneously, maintaining speed while improving reliability through distributed redundancy.
Solution Approach 2:
The patent introduces smart contracts as intermediaries that automatically verify and manage data access requests. These self-executing contracts enforce access control rules and validate transactions without manual intervention, maintaining fast access speeds while ensuring security and reliability through automated verification mechanisms.
2Reliability
If blockchain technology is implemented for data storage, then data security and reliability are improved, but system complexity increases
Solution Approach 1:
The patent implements self-service mechanisms through smart contracts that automatically handle data verification, access control, and transaction validation. The system self-manages security protocols and consensus verification without requiring external intervention, reducing operational complexity while maintaining high security standards.
Solution Approach 2:
The patent creates a universal blockchain platform that handles multiple functions including data storage, access control, transaction validation, and smart contract execution within a single integrated system. This multi-functionality reduces the need for separate security systems and simplifies overall system architecture despite the advanced capabilities provided.
3Reliability
If distributed blockchain network is used, then system reliability is improved, but energy consumption increases due to consensus mechanisms
Solution Approach 1:
The patent changes the consensus mechanism parameters by transitioning from proof-of-work to proof-of-stake or other energy-efficient algorithms. This parameter change maintains data integrity and reliability through distributed consensus while dramatically reducing the computational energy required for transaction validation and block verification.
Solution Approach 2:
The patent uses efficient data replication strategies where critical data blocks are copied across necessary nodes, while less critical data uses lighter synchronization protocols. This selective copying approach maintains data integrity across the distributed network while minimizing the energy consumption associated with full data replication across all nodes.

AI summary
An information transmission method based on blockchain, which includes the following steps. A sender creates a transmission contract on a blockchain, submits a digest of to-be-transmitted information to the transmission contract, and sends the ciphertext of the to-be-transmitted information, an address of a receiver and an address of the transmission contract to a first transmission node of a transmission network. The first transmission node sends the ciphertext of the to-be-transmitted information, an address of the receiver and an address of the transmission contract to a second transmission node in a point-to-point manner. The second transmission node receives and delivers the ciphertext of the to-be-transmitted information and the address of the transmission contract to the receiver, and generates and submits a receipt acknowledgement to the transmission contract. This application also provides an information transmission system and device, and a computer-readable storage medium.
