Reactive Blockchain
summary
Shows a working React frontend talking to Ethereum via React + web3 + MetaMask, deploys a tiny Solidity smart contract and wires UI calls to on‑chain transactions, with live connection to a node and reads from the chain. Reports practical limits: gas costs and slow reads, recommends lazy loading/caching, and provides links to code and a demo; the example deploys and returns data but emphasizes deployment cost and latency.
