Ethereum for Java Developers
summary
Shows that Ethereum behaves like a distributed object platform rather than magic hype and demonstrates a full Java workflow: write a simple Solidity Storage contract with getter and setter, compile to EVM bytecode, generate a Java proxy with the web3j maven plugin, and deploy to a local Ganache node using web3j and a hardcoded private key. Deployment and synchronous calls work in the demo, but on‑chain computation is slow and expensive so heavy logic must stay off‑chain and only hashes or pointers belong on chain.
