When running `embark blockchain` followed by `embark run` previously, logs generated in the standalone `embark blockchain` process were black boxed and not accessible to the main Embark process. This is fixed by creating a client IPC connection in the `embark blockchain` process that connects to the IPC server connection running in `embark run`. The connection is made by way of polling `ipc.connect` and continues polling even after a connection is made in case `embark run` is killed and restarted without restarting `embark blockchain`. `LogHandler` was introduced to extrapolate functionality used in `ProcessLauncher` that needed to also be used in the standalone blockchain process. It also caps the number of logs that are stored in memory per process by a constant value defined in `constants.json`. A `blockchain_listener` was module was created (and run inside of `embark run`) that listens for logs emitted by the `embark blockchain` client IPC and runs them through the `LogHandler`. Additionally, this module registers the API endpoints needed to handle requests for blockchain process logs in the cockpit (which were 404’ing before). # Conflicts: # lib/modules/blockchain_process/blockchain.js |

What is Embark
Embark is a framework that allows you to easily develop and deploy Decentralized Applications (DApps).
A Decentralized Application is a serverless html5 application that uses one or more decentralized technologies.
Embark currently integrates with EVM blockchains (Ethereum), Decentralized Storages (IPFS), and Decentralized communication platforms (Whisper and Orbit). Swarm is supported for deployment.
With Embark you can:
Blockchain (Ethereum)
- Automatically deploy contracts and make them available in your JS code. Embark watches for changes, and if you update a contract, Embark will automatically redeploy the contracts (if needed) and the dapp.
- Contracts are available in JS with Promises.
- Do Test Driven Development with Contracts using Javascript.
- Keep track of deployed contracts; deploy only when truly needed.
- Manage different chains (e.g testnet, private net, livenet)
- Easily manage complex systems of interdependent contracts.
Decentralized Storage (IPFS)
- Easily Store & Retrieve Data on the DApp through EmbarkJS. Including uploading and retrieving files.
- 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.
