Embark is a framework used for developing and deploying DApps (Decentralized Apps) using one or more decentralized technologies. The tools and functionalities provided by the Embark make the DApp development process easy and productive. It reduces the interaction between the front end of application and smart contract so that the application can run faster on the network. The technology uses IPFS protocol to store and manage files across the decentralized network. ‘Whisper’ and ‘Orbit’ communication platforms streamline the communication process in Embark. The platform performs automatic deployment of smart contract and ensures the redeployment if the contract has undergone any changes

2. Introduction
• Embark is a framework used for developing and deploying DApps (Decentralized Apps) using one
or more decentralized technologies. The tools and functionalities provided by the Embark make
the DApp development process easy and productive. It reduces the interaction between the front
end of application and smart contract so that the application can run faster on the network. The
technology uses IPFS protocol to store and manage files across the decentralized network.
‘Whisper’ and ‘Orbit’ communication platforms streamline the communication process in
Embark. The platform performs automatic deployment of smart contract and ensures the
redeployment if the contract has undergone any changes

3. • Embark currently integrates with Ethereum, decentralized storages like IPFS, and decentralized
communication platforms like Whisper and Orbit. Using embark, it is possible to manage different
chains like testnet, private net, livenet etc. And the smart contracts in solidity and serpent can be
built and it is deployable with embark. The dashboard of Embark will provide the tracking
information like the current state of the contracts, the environment it is using and what Embark is
doing currently etc.

4. • How to Install embark?
• Prerequisites:
 geth (1.5.8 or higher)
node (6.9.1 or higher)
• Open terminal and run the below-given codes
npm -g install embark
• To run it on a simulator instead of a real Ethereum node, run the below-given code
npm -g install ethereumjs-testrpc

5. • Creating a DApp with Embark
 Generally, a typical DApp in embark consists of 2 sections.
1. Smart contracts
This section will contain the business logic of the DApp. It is written in either solidity or serpent
2. User Interface
The user interface through which the user interacts with the app
• To create a DApp in embark simply run this code
 embark new <DApp name>

6. • This code will initialize a predefined template and creates a directory structure

7. • Directory Structure
The default directory structure created by the above code

8. • How to to run an embark DApp?
There are two options available to run a DApp.
1. Using a real Ethereum node.
• The code will run the app in an Ethereum network.
embark blockchain
• [keep in mind that at least 2GB of free RAM is required for smooth execution of above
operation]

9. 2. Using an Ethereum rpc simulator
 This method is useful in the development phase.The code will run the
app in a test net.
 embark simulator
 After executing either of the above steps, now open a new terminal and
run,
 embark run

10. • The code will deploy the smart contract files in app/contracts directory and it also turns the
terminal into the embark dashboard. See the figure.

11. • The dashboard makes it easy to track and manage the contracts. All the contracts in the App will
appear in the contract section along with the address and current status. If any changes are made
in any file, the embark will automatically redeploy the contracts and update the JS bindings. Thus
it is reflected in our DApp almost instantly. The user can also interact with the DApp from the
console. The web interface of the same is available at http://localhost:8000. And all above
functionalities can be performed from the web interface also.
