Problem
The existing systems for renewable energy transactions lack reliability and security, making it difficult to ensure transparent and fair transactions between renewable energy producers and consumers.
Innovation Solution
An RE100 energy transaction system using a blockchain network with first and second blockchain nodes that generate and share power production and sales information, and power purchase information, respectively, along with a certification authority for authentication, and a management server to verify transaction reliability, utilizing smart contracts to secure and record transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a blockchain network is implemented for RE100 energy transactions, then security and reliability of transactions are improved, but device complexity and system infrastructure requirements worsen
Solution Approach 1:
The system segments the blockchain network into multiple types of nodes (power generator nodes, power consumer nodes, certification authority nodes, management server nodes) with specialized functions. Each node type handles specific transaction aspects, dividing the complex blockchain implementation into manageable, specialized components that improve reliability while organizing complexity systematically
Solution Approach 2:
The patent introduces intermediary components including a certification authority that verifies node identities and a management server that coordinates transactions. These intermediaries mediate between participants, ensuring secure and reliable transactions without requiring every node to directly verify every other node, thus improving transaction reliability while managing system complexity through centralized coordination functions
2Loss of information
If blockchain nodes store and share power production and purchase information, then transparency of transactions is improved, but information storage requirements and processing overhead worsen
Solution Approach 1:
Different blockchain nodes store different types of information locally based on their function: power generator nodes store production information, power consumer nodes store purchase information, and the management server stores credential information. This local quality approach ensures transaction transparency through distributed storage while reducing the total data storage requirement at each node compared to storing all transaction data centrally
3Reliability
If a certification authority performs authentication procedures, then security of the blockchain network is improved, but processing time for node registration and transaction verification worsens
Solution Approach 1:
The certification authority performs authentication procedures in advance during node registration, issuing credentials before nodes begin transacting. This preliminary action ensures network security through proper verification while reducing verification time during actual transactions, as the authentication work has already been completed beforehand
