19. Let’s stop there! - This just seems like too much work. And we haven’t even scratched the surface - There has to be a better way
20. Ethereum Dev Frameworks - https://truffleframework.com/ - https://embark.status.im/
21. DEMO
22. Truffle https://truffleframework.com/ - Easy to get started - “Boxes” for Angular, React - Just like building a normal web app, but integrating with Blockchain
23. Embark https://embark.status.im/ - Built by popular DApp - Status.im - New but excellent support for Whisper and IPFS
24. Whisper - Pub/Sub style messaging system - Plausible deniability
25. IPFS https://ipfs.io/ - Redundant distributed web - Hosted platform for HTML/CSS - Deploy Truffle or Embark apps on the platform for pure decentralization
