Consensys Academy Final Project -ViewDapp for immortal Images

This project is part of final submission for consensys academy training. This app allows a user to store an image on IPFS and store its hash to Ethereum blockchain test network via deployed smart contract. This

Above screen will show Ethereum address of user and select button to select an image. Once image is selected, application will upload image to IPFS nodes through Infura. Below screen will show status of progress:

Then it will store hash returned by IPFS to Ethereum via smart contract.

UI application can retrieve all historic submissions along with current submission to show on UI. Just refresh if latest image is not showing and you image should show up as on below screen:

This is just a POC for a DApp with IPFS, it can be further extended to evoleve as decentralized Instagram.

5. Run the contract deployment command, as shown below:

Run truffle migrate — compile-all — reset — network ganache This step will deploy contracts and create ABI.

6. Truffle Test

Run truffle test to execute tests designed for smart contract. This step will run all test cases designed for smart contract.

7. Build for Frondend

Run ng build to build the project. The build artifacts will be stored in the dist/ directory.

8. Run and launch UI application to interact with deployed smart contract

Run ng serve for a dev server. Navigate to http://localhost:4200/. The app will automatically reload if you change any of the source files.

9. Steps to Interact with UI

As per project requirement, it should show you your address on top righ corner as shown in above screenshots as well. Also, follow instructions written along with above screenshots in case of any doubt. Rest, application have simple functionality and should not be complex to use.
