4. Problem
 Technology for the problem of decentralized consensus
 Consensus
 Two or more parties
 Parameter of interest for the parties
 Value of parameter saved with a central authority
 Central authority enforces consensus
 Decentralized consensus
 Two or more parties
 Parameter of interest for the parties
 Value of parameter saved with every one
 Network agrees on a protocol of consensus

16. Ethereum
Development
Framework
• Built-in smart
contract compilation,
linking, deployment
and binary
management
• Automated contract
testing for rapid
development – Mocha
and Chai
• Scriptable deployment
& migrations
framework
• Network management
for deploying to both
public & private
networks
• External packages –
npm and ethpm
• Interactive console for
contracts
Truffle is a development environment, testing framework and asset
pipeline for Ethereum, aiming to make life as an Ethereum developer
easier.

17. Ethereum
Development
Framework
One-click blockchain
Quickly fire up a personal Ethereum blockchain which you can use to run tests,
execute commands, and inspect state while controlling how the chain operates.

18. Ethereum
Development
Framework
Framework for serverless Decentralized Applications
using Ethereum, IPFS and other platforms
Blockchain (Ethereum)
•Automatically deploy contracts
and make them available in your
JS code.
•Do Test Driven Development
•Keep track of deployed contracts;
deploy only when truly needed.
•Easily manage complex systems
of interdependent contracts.
Decentralized Storage (IPFS)
•Easily Store & Retrieve Data on
the DApp through EmbarkJS.
•Deploy the full application to
IPFS or Swarm.
Decentralized Communication (Whisper,
Orbit)
• Easily send/receive messages through
channels in P2P through Whisper or
Orbit.
Web Technologies
• Integrate with any web technology
including React, Foundation, etc..
• Use any build pipeline or tool you wish,
including grunt, gulp and webpack.
