Developing Distributed Apps on the Ethereum Blockchain
summary
Explains how Ethereum generalizes Bitcoin and runs Solidity token contract code on a stack-based EVM; builds a Pyramid token (buy price rises, sell returns last price) with on-chain storage and nonce tracking, deploys and tests it in Remix JavaScript VM, exercises buy/sell paths and observes state changes and balances, uses IPFS-hosted front end served by a Mist-like browser; notes gas accounting (example gas price ~0.001 Ether) and demonstrates the app working across devices via the IPFS hash.
