Angular, the Blockchain, and You
summary
Explains how a runnable local blockchain and a slow in-browser miner produce real 10-second block times, shows a Solidity MetaCoin smart contract (constructor, balance mapping, Transfer event), compiles and deploys with truffle, and calls contract functions from Angular via web3 and truffle-contract. Demonstrates Merkle-root verification and mining incentives, and wires contract events to RxJS-driven UI updates so balances auto-refresh when the Transfer event is mined.
