Blockchain POC on DApps in Java

0 votes
I wanted to develop a web application using Ethereum, Infura, and web3J.. can you share your inputs to quickStart, I see more theoretical stuff & don't found any practical examples to step forward using web3j.. I want to store user earned points on solving some puzzles with some metadata like points creation date, expiry date, puzzle ID & etc in the blockchain.

How to model & store the above information...?

You could be a little more specific in your question. Are you sure you need interaction with a Java project, or maybe pure Ethereum implementations would suffice?

For example: If the user interacts with this puzzle in a Java application but you want to store the user's data in the blockchain, then you need Web3j to interact with Ethereum. But maybe the puzzle can be implemented directly into the blockchain. Then you don't need Web3j at all.
