Ultron
Smart plugs which can monitor the usage of electricity and with help of blockchain we can make an ecosystem that incentivizes the user for consuming less electricity.
About
The problem it solves 1. Reduces and encourages people to save electricity. 2. In the future, it can allow use of decentralized power
How it's made
Challenges we ran into We had some difficulties bringing different things to work together(like the IPFS, the backend, the smart contract, etc). We spent some time discussing different algorithms and design patterns that would serve the purpose. We solved the issues mostly by reading the docs in depth.
