Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of transparency and verification in the energy market regarding the origin of renewable energy, making it difficult for consumers to confirm whether the electricity they receive is produced using renewable sources, despite the environmental benefits of such energy.
Innovation Solution
A blockchain-based tracking system that stores energy information and certificate issuance status, allowing for the tracking and verification of energy production methods, enabling users to request and determine the validity of renewable energy certificates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a certificate system is introduced to verify renewable energy production, then transparency and verification of energy origin are improved, but system complexity and operational difficulty increase
Solution Approach 1:
The patent introduces a certificate issuance server as an intermediary component that mediates between the blockchain network and external requestors. This server receives issuance requests, interacts with the blockchain nodes to verify renewable energy production, and returns certificate status. By placing this intermediary layer, the system maintains simplicity for end users while implementing complex verification logic internally, thus resolving the contradiction between verification reliability and system complexity.
Solution Approach 2:
The system implements a feedback mechanism where the certificate issuance server continuously monitors the blockchain for certificate issuance status and returns this information to requestors. The server receives issuance requests, processes them through the blockchain network, and provides feedback on whether certificates have been issued. This automated feedback loop ensures reliable verification while reducing operational complexity by eliminating manual verification processes.
2Loss of information
If blockchain technology is used to store energy information, then data transparency and immutability are improved, but system complexity and implementation difficulty increase
Solution Approach 1:
The patent extracts the complex blockchain implementation details into a separate, self-contained system. The certificate issuance server handles all blockchain interactions, while external users only interact with the simplified server interface. This extraction isolates the complexity of blockchain technology into a manageable component, maintaining information transparency benefits while reducing overall system implementation complexity for end users.
Solution Approach 2:
The certificate issuance server acts as an intermediary that shields users from blockchain complexity. Instead of requiring users to directly interact with the blockchain network, understand its protocols, or manage cryptographic keys, the server handles all blockchain operations internally. This intermediary layer preserves the transparency and immutability benefits of blockchain while presenting a simple, user-friendly interface.
3Measurement precision
If certificate issuance tracking is implemented, then consumer verification capability is improved, but processing time and operational overhead increase
Solution Approach 1:
The certificate issuance server implements continuous monitoring of the blockchain network for certificate issuance events. Instead of waiting for manual queries or periodic checks, the system continuously tracks the blockchain state, maintaining an up-to-date record of issued certificates. This continuous operation eliminates waiting time for verification and provides immediate, precise certificate status information to consumers, thus improving measurement precision without significant time loss.
Solution Approach 2:
The system performs preliminary actions by pre-processing and storing certificate issuance information as it becomes available on the blockchain. The server proactively retrieves and caches certificate data before users need to verify it, so when verification requests are made, the information is already prepared and readily available. This preliminary action reduces verification time while maintaining precise tracking of certificate issuance status.
Data Source
AI summary
A system for tracking exchange of energy, includes: a memory that stores energy information generated by each node of a plurality of nodes in a blockchain network, the energy information indicating a production method used for producing the energy and an issuance status of a certificate that certifies the production method; and circuitry that receives, from an information processing apparatus, issuance request information requesting issuance of the certificate for the production method of energy, and determines an issuance status of the certificate for the production method of energy, based on the issuance request information that is received.
