Client Challenge
A distributed electrical energy exchange platform (DApp) connects electricity consumers directly with green energy producers to enable cost-effective, borderless electricity trading.
What We Did
- Over two months TORI in conjunction with our partner designed the platform’s architecture and engineered a fully functional prototype of the target platform, implementing both the front-end and the back-end
Frameworks and Tools used:
- Java, Spring, Tomcat for the backend
- REST/JSON for data communications
- PostgresSQL for data management
- Metamask and web3.js for integration with Ethereum blockchain
- Smart contracts for business logic
- Truffle for smart contract development
- Angular 4 for web frontend (UI)
Outcome & Results
- The platform uses Ethereum blockchain to enable immutable transactions and kWh token ownership
- Smart contracts are used to describe the business logic related to kWh token manipulation.
- Metamask Chrome plugin is used to ensure direct user connection to Ethereum blockchain from DApp without any third-party involvement.
- Planned integration with the largest European electrical energy market
- Blockchain integration different application behaviour when working in a local environment (testrpc) and global testnet (Ropsten)
- Extensive functional testing carried out to ensure correct DApp behaviour
- The Truffle framework did not offer out-of-the-box support for integration with other JavaScript frameworks (solved through custom integration)
