feat(@embark/quorum): Add support for Quorum blockchains
Add support for *connecting to* Quorum blockchains. This plugin will not start a Quorum node or nodes automatically as Embark does with other chains. This plugins supports deploying contracts publically and privately using the Tessera private transaction manager. This plugin supports sending of public and private transactions using the Tessera private transaction manager. Add ability to skip bytecode checking as part of the contract deployment process. Instruct the deployer to skip checking if the contract bytecode exists on-chain before deploying the contract. This is important in the case of having many private nodes in a network because if a contract is deployed privately to node 1 and 7, running Embark on node 2 should skip the bytecode check as the contract *is not* deployed on node 2, nor do we want it deployed on node 2. If the bytecode check was in place, Embark would have deployed it to node 2 and therefore not adhered to the privacy needs. Add Ethereum contract deployer for Quorum, allowing for deploying of public and private contracts using `privateFor` and `privateFrom` (see Contract config updates below). Add web3 extensions enabling specific functionality for Quorum. Extensions includes those provided by [`quorum-js`](https://github.com/jpmorganchase/quorum.js), as well as some custom monkeypatches that override web3 method output formatting, including: - web3.eth.getBlock - web3.eth.getTransaction - web3.eth.getTransactionReceipt - web3.eth.decodeParameters DApps wishing to take advantage of these overrides will need to patch web3 as follows: ``` import {patchWeb3} from "embark-quorum"; import Web3 from "web3"; let web3 = new Web3(...); web3 = patchWeb3(web3); ``` Add support for sending a raw private transaction in the Quorum network. This includes running actions from the proxy after an `eth_sendTransaction` RPC request has been transformed in to `eth_sendRawTransaction` after being signed. fix(@embark/transaction-logger): Fix bug when sending a 0-value transaction. Add `originalRequest` to the proxy when modifying `eth_sendTransaction` to `eth_sendRawTransaction`, so that the original transaction parameters (including `privateFor` and `privateFrom`) can be used to sign a raw private transaction in the `eth_sendRawTransaction` action. Added the following properties on to blockchain config: - *`client`* `{boolean}` - Allows `quorum` to be specified as the blockchain client - *`clientConfig/tesseraPrivateUrl`* `{string}` - URL of the Tessera private transaction manager ``` client: "quorum", clientConfig: { tesseraPrivateUrl: "http://localhost:9081" // URL of the Tessera private transaction manager } ``` Added the following properties to the contracts config: - *`skipBytecodeCheck`* `{boolean}` - Instructs the deployer to skip checking if the bytecode of the contract exists on the chain before deploying the contract. This is important in the case of having many private nodes in a network because if a contract is deployed privately to node 1 and 7, running Embark on node 2 should skip the bytecode check as the contract *is not* deployed on node 2, nor do we want it deployed on node 2. If the bytecode check was in place, Embark would have deployed it to node 2 and therefore not adhered to the privacy needs. - *`privateFor`* `{string[]}` - When sending a private transaction, an array of the recipient nodes' base64-encoded public keys. - *`privateFrom`* `{string}` - When sending a private transaction, the sending party's base64-encoded public key to use ``` environment: { deploy: { SimpleStorage: { skipBytecodeCheck: true, privateFor: ["ROAZBWtSacxXQrOe3FGAqJDyJjFePR5ce4TSIzmJ0Bc"], privateFrom: "BULeR8JyUWhiuuCMU/HLA0Q5pzkYT+cHII3ZKBey3Bo=" } } }, ``` - *`proxy:endpoint:http:get`* - get the HTTP endpoint of the proxy regardless of blockchain settings - *`proxy:endpoint:ws:get`* - get the WS endpoint of the proxy regardless of blockchain settings - *`runcode:register:<variable>`* - when variables are registered in the console using `runcode:register`, actions with the name of the variable (ie `runcode:register:web3`) will be run *before* the variable is actually registered in the console. This allows a variable to be modified by plugins before being registered in the console.

# `embark-quorum`
|
||||
|
||||
> Quorum blockchain client plugin for Embark
|
||||
|
||||
`embark-quorum` is an Embark plugin that allows ÐApps to **connect to** Quorum blockchains. This plugin will not start a Quorum node or nodes automatically as Embark does with other clients.
|
||||
|
||||
Using this plugin, you can:
|
||||
- deploy contracts publically and privately to a Quorum network using the Tessera private transaction manager.
|
||||
- send public and private transactions on a Quorum network using the Tessera private transaction manager.
|
||||
|
||||
## Overview
|
||||
To use the Embark Quorum plugin, you'll need to do the following, which we'll cover in more detail in the sections below:
|
||||
1. [Initialise and run a Quorum network](#1-initialise-and-run-a-quorum-network), such as the [7nodes example](https://github.com/jpmorganchase/quorum-examples/tree/master/examples/7nodes)
|
||||
2. [Install the `embark-quorum` plugin in your ÐApp](#2-install-the-embark-quorum-plugin-in-your-ÐApp)
|
||||
3. [Configure your ÐApp's blockchain config](#3-configure-your-ÐApps-blockchain-config)
|
||||
4. [Configure your ÐApp's contract config (if necessary)](#4-configure-your-ÐApps-contract-config)
|
||||
5. [Run Embark and deploy a private contract](#5-run-embark-and-deploy-a-private-contract)
|
||||
6. [Sending a private transaction](#6-sending-a-private-transaction)
|
||||
|
||||
## 1. Initialise and run a Quorum network
|
||||
In order to get a Quorum network up quickly for development, the easiest path is to download the Quorum/Tessera binaries and use them to run the cloned 7nodes example.
|
||||
1. Download the latest Quorum binary from https://github.com/jpmorganchase/quorum/releases. Let's say it was downloaded to `/repos/jpmorganchase/quorum/build/bin/geth`.
|
||||
2. Update your `PATH` environment variable such that `geth` points to Quorum geth:
|
||||
```
|
||||
export PATH=/repos/jpmorganchase/quorum/build/bin:$PATH
|
||||
```
|
||||
3. Download the latest Tessera jar (`tessera-app-{version}-app.jar`, ie `tessera-app-0.10.3-app.jar`) from https://github.com/jpmorganchase/tessera/releases.
|
||||
4. Update your `TESSERA_JAR` environment variable to point to the downloaded Tessera jar:
|
||||
```
|
||||
export TESSERA_JAR=/path/to/tessera-app-0.10.3-app.jar
|
||||
```
|
||||
5. Clone the 7nodes example repo:
|
||||
```
|
||||
git clone https://github.com/jpmorganchase/quorum-examples
|
||||
cd examples/7nodes
|
||||
```
|
||||
6. Initialise Quorum using the desired consensus (`istanbul`, `raft`, `clique`):
|
||||
```
|
||||
# ./{consensus}-init.sh
|
||||
./istanbul-init.sh
|
||||
```
|
||||
7. Start Quorum using the desired consensus from step 6:
|
||||
```
|
||||
# ./{consensus}-start.sh tessera
|
||||
./istanbul-start.sh
|
||||
```
|
||||
> **NOTE:** the default 7nodes example does not start Quorum geth with WebSockets. We can get around this by updating `./istanbul-start.sh` before executing it, as per https://github.com/jpmorganchase/quorum-examples/pull/221. As an alternative, clone [the fork with these changes](https://github.com/emizzle/quorum-examples) (on the `7nodes-websocket-support` branch) in Step 5 instead.
|
||||
|
||||
After a few moments, you should have 7 Quorum nodes up and running.
|
||||
|
||||
To stop the network:
|
||||
```
|
||||
./stop.sh
|
||||
```
|
||||
|
||||
For more information on how to get the 7nodes example up and running, including information on using Vagrant and Docker, see https://github.com/jpmorganchase/quorum-examples.
|
||||
|
||||
## 2. Install the `embark-quorum` plugin in your ÐApp
|
||||
|
||||
### Creating a ÐApp if needed
|
||||
First, ensure you have a ÐApp set up. We will be using the Embark's demo ÐApp in this README, which can be created using `embark demo`:
|
||||
```
|
||||
# /bin/bash
|
||||
|
||||
embark demo
|
||||
cd embark_demo
|
||||
```
|
||||
|
||||
For more information on how to get started with the Embark Demo, view our [Quick Start guide](https://framework.embarklabs.io/docs/quick_start.html).
|
||||
|
||||
### Installing `embark-quorum` in your ÐApp
|
||||
To install `embark-quorum` in to our ÐApp, we can add `embark-quorum` to our `packages.json`, then run `npm` or `yarn`:
|
||||
```
|
||||
# package.json
|
||||
"dependencies": {
|
||||
"embark-quorum": "5.3.0"
|
||||
}
|
||||
```
|
||||
Then install the package with your package manager.
|
||||
```
|
||||
# /bin/bash
|
||||
npm i
|
||||
// OR
|
||||
yarn
|
||||
```
|
||||
Next, update our ÐApp's `embark.json` to include the `embark-quorum` plugin:
|
||||
```
|
||||
# embark.json
|
||||
"plugins": {
|
||||
"embark-quorum": {}
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
## 3. Configure your ÐApp's blockchain config
|
||||
We'll need to update our `blockchain.js` configuration to instruct Embark on how to connect to the seven Quorum nodes we now have running.
|
||||
|
||||
The best option is to create an environment for each node in the network, so that we can connect to each node individually. The `rpcPort` and `wsPort` are determined by the `./{consensus}-init.sh` script run in step 1.6.

||||
|
||||
Notice that by setting the `tesseraPrivateUrl` in the `default` environment, it is shared by all the environments defined.
|
||||
|
||||
```
|
||||
# config/blockchain.js
|
||||
|
||||
module.exports = {
|
||||
// default applies to all environments

|
||||

||||

|
||||

|
||||
}
|
||||
},
|

|

|

|
||||
|

}
|
||||
};
|
||||
```
|
||||
|
||||
## 4. Configure your ÐApp's contract config
|
||||
We'll need to update our `contracts.js` configuration to instruct Embark on how to deploy our contracts.
|
||||
|
||||
There are two important things to notice in this configuration. First, notice that `nodeone` has the field `privateFor`. This is telling Quorum to deploy the contract privately to Node 7, as indicated by Node 7's public key in the `privateFor` field. The means Node 1 and Node 7 will be privy to this contract's values once deployed.
|
||||
|
||||
Also notice that we include `skipBytecodeCheck: true` for all nodes that we *assume should have the contract deployed in the **network**, but not deployed to that **node***. In our example, Node 1 doesn't need `skipBytecodeCheck` because it is deploying the contract and can let Embark handle tracking of the contract deploys. Node 7 also doesn't need this check because Node 1 will have privately deployed the contract to Node 1 and Node 7, so we know the bytecode will exist on Node 7. However, all other Nodes need `skipBytecodeCheck: true`, because the bytecode will **not exist** on those nodes and when Embark connects to any of those environments, we are going to rely on Embark's deployment tracking feature to determine if the contract has been deployed to the network, **instead of** checking to see if the bytecode for that contract exists on the node Embark is connected to. Please [check out the docs](https://framework.embarklabs.io//docs/contracts_configuration.html#Skipping-bytecode-check) for more information on this topic.
|
||||
|
||||
```
|
||||
# config/contracts.js
|
||||
|
||||
module.exports = {
|
||||
// default applies to all environments
|
||||
default: {
|
||||
// order of connections the DApp should connect to
|
||||
dappConnection: [
|
||||
"$EMBARK",
|
||||
"$WEB3", // uses pre existing web3 object if available (e.g in Mist)
|
||||
"ws://localhost:8546",
|
||||
"http://localhost:8545"
|
||||
],
|
||||
gas: "auto",
|
||||
},
|
||||
|
||||
nodeone: {
|
||||
deploy: {
|
||||
SimpleStorage: {
|
||||
fromIndex: 0,
|
||||
args: [100],
|
||||
privateFor: ["ROAZBWtSacxXQrOe3FGAqJDyJjFePR5ce4TSIzmJ0Bc="]
|
||||
}
|
||||
}
|
||||
},
|
||||
nodetwo: {
|
||||
deploy: {
|
||||
SimpleStorage: {
|
||||
skipBytecodeCheck: true
|
||||
}
|
||||
}
|
||||
},
|
||||
nodethree: {
|
||||
deploy: {
|
||||
SimpleStorage: {
|
||||
skipBytecodeCheck: true
|
||||
}
|
||||
}
|
||||
},
|
||||
nodefour: {
|
||||
deploy: {
|
||||
SimpleStorage: {
|
||||
skipBytecodeCheck: true
|
||||
}
|
||||
}
|
||||
},
|
||||
nodefive: {
|
||||
deploy: {
|
||||
SimpleStorage: {
|
||||
skipBytecodeCheck: true
|
||||
}
|
||||
}
|
||||
},
|
||||
nodesix: {
|
||||
deploy: {
|
||||
SimpleStorage: {
|
||||
skipBytecodeCheck: true
|
||||
}
|
||||
}
|
||||
},
|
||||
nodeseven: {}
|
||||
};
|
||||
```
|
||||
|
||||
## 5. Run Embark and deploy a private contract
|
||||
Now that we have our ÐApp set up, let's run Embark and see the private contract deployment in action. We are going to deploy the `SimpleStorage` contract privately between Nodes 1 and 7 (based on the `privateFor` parameter specified in the contract configuration for the `nodeone` environment), and witness how we can only view the contract's values in Nodes 1 and 7, and not in Nodes 2 - 5.
|
||||
|
||||
First, let's run Embark in console mode in our `nodeone` environment, ensuring we connect to Node 1 in our 7nodes example:
|
||||
```
|
||||
# /bin/bash
|
||||
|
||||
embark console nodeone
|
||||
```
|
||||
You should see all the normal output of `embark run`, including information on how the contract `SimpleStorage` was deployed:
|
||||
```
|
||||
compiling solidity contracts...
|
||||
deploying contracts
|
||||
Deploying SimpleStorage with 151414 gas at the price of 0 Wei. Estimated cost: 0 Wei (txHash: 0xecb96cebf2a4da17206d8b225b77f2a84e3ec2ae1a10cd3f95ddc094381ec5d1)
|
||||
SimpleStorage deployed at 0x9d13C6D3aFE1721BEef56B55D303B09E021E27ab using 0 gas (txHash: 0xecb96cebf2a4da17206d8b225b77f2a84e3ec2ae1a10cd3f95ddc094381ec5d1)
|
||||
finished deploying contracts
|
||||
```
|
||||
Once the ÐApp is finished webpacking, you should see the console prompt:
|
||||
```
|
||||
Embark (nodeone) >
|
||||
```
|
||||
In this prompt, enter `SimpleStorage.get()` so we can find out what our current value stored in the contract is:
|
||||
```
|
||||
Embark (nodeone) > SimpleStorage.get()
|
||||
# 100
|
||||
```
|
||||
We can see that the value returned is the value we provided in our `SimpleStorage` constructor `args` in the contracts configuration. So far, so good.
|
||||
|
||||
Now, let's kill our instace of Embark with `Ctrl+c`, and then spin up a new instance in the `nodeseven` environment.
|
||||
```
|
||||
<ctrl+c>
|
||||
embark console nodeseven
|
||||
```
|
||||
The output, this time, will be a little bit different. Notice that Embark understands that the contract has been deployed to Node 7 (due to the bytecode check):
|
||||
```
|
||||
deploying contracts
|
||||
SimpleStorage already deployed at 0x9d13C6D3aFE1721BEef56B55D303B09E021E27ab
|
||||
finished deploying contracts
|
||||
```
|
||||
Now, do the same thing as before and retrieve the value stored in the contract:
|
||||
```
|
||||
Embark (nodeone) > SimpleStorage.get()
|
||||
# 100
|
||||
```
|
||||
Again, as expected, we get the value of 100, matching the constructor arguments. This is expected because Node 1 deployed the `SimpleStorage` contract privately between nodes 1 and 7.
|
||||
|
||||
Let's take this one step further and check the value stored in `SimpleStorage` on a node that was not included in the private contract deploy.
|
||||
|
||||
Exit the current Embark instance with `ctrl+c`, then start up a new instance in the `nodetwo` environment:
|
||||
```
|
||||
<ctrl+c>
|
||||
embark console nodetwo
|
||||
```
|
||||
Notice the warning that the bytecode check is skipped, and also that Embark knows the contract has already been deployed, **even though the bytecode doesn't exist on Node 2**:
|
||||
```
|
||||
compiling solidity contracts...
|
||||
deploying contracts
|
||||
WARNING: Skipping bytecode check for SimpleStorage deployment. Performing an Embark reset may cause the contract to be re-deployed to the current node regardless if it was already deployed on another node in the network.
|
||||
SimpleStorage already deployed at 0x9d13C6D3aFE1721BEef56B55D303B09E021E27ab
|
||||
finished deploying contracts
|
||||
```
|
||||
Again, let's see now what Node 2 has stored for the `SimpleStorage` contract value:
|
||||
```
|
||||
Embark (nodetwo) > SimpleStorage.get()
|
||||
# 0
|
||||
```
|
||||
The result is `0`, which is exepcted because Node 2 does not contain the bytecode for `SimpleStorage` and does not have its values stored in its Ethereum state.
|
||||
|
||||
## 6. Sending a private transaction
|
||||
Let's see how the `embark-quorum` plugin allows us to send private transactions.
|
||||
|
||||
First, run an Embark console in the `nodeone` environment to see what the current value of the `SimpleStorage` contract is.
|
||||
|
||||
```
|
||||
# /bin/bash
|
||||
|
||||
embark console nodeone
|
||||
```
|
||||
Once started, get our contract value in the console prompt:
|
||||
```
|
||||
Embark (nodeone) > SimpleStorage.get()
|
||||
# 100
|
||||
```
|
||||
Now, let's update this value only for Node 7. In the console, we're going to send a private transaction between Node 1 and Node 7. This transaction is simply going to set the `SimpleStorage` value to `333` by calling the `SimpleStorage.set(333)` method in a transaction. Run each of these lines individually in the console:
|
||||
```
|
||||
Embark (nodeone) > from = web3.eth.defaultAccount
|
||||
Embark (nodeone) > privateFor = ['ROAZBWtSacxXQrOe3FGAqJDyJjFePR5ce4TSIzmJ0Bc=']
|
||||
Embark (nodeone) > await SimpleStorage.methods.set(333).send({ from, privateFor })
|
||||
```
|
||||
We can check that the transaction set our `SimpleStorage` value to `333`:
|
||||
```
|
||||
Embark (nodeone) > SimpleStorage.get()
|
||||
# 333
|
||||
```
|
||||
Now, let's check Node 7:
|
||||
```
|
||||
<ctrl+c>
|
||||
embark console nodeseven
|
||||
```
|
||||
Then, in the console prompt:
|
||||
```
|
||||
Embark (nodeseven) > SimpleStorage.get()
|
||||
# 333
|
||||
```
|
||||
Great! We have privately set our `SimpleStorage` contract value only in Node 7.
|
||||
|
||||
|
||||
## Conclusion
|
||||
Now you should have a good idea of how to run a Quorum network and use Embark to deploy public and private contracts, and send public and private transactions.
|
||||
|
||||
In addition to running on a network of multiple Quorum nodes, `embark-quorum` works with any number of Quorum nodes, including one.
|
||||
|
||||
Please feel free to explore all the possibilities of Quorum and Embark in your own ÐApp, and [report any issues found](https://github.com/embarklabs/embark/issues).

Having the file referenced above under version control ensures that other users of our project don't redeploy the Smart Contracts on different platforms.
|
||||
|
||||
### Skipping bytecode check
|
||||
By default, before deploying a contract, Embark will check if the bytecode for the contract already exists on-chain at the address that is tracked by Embark. If the bytecode does not exist, or is different, Embark will deploy the contract for you. We can skip a bytecode check, to ensure that Embark relies on the deployment tracker to determine if the contract has already been deployed or not.
|
||||
|
||||
```
|
||||
environment: {
|
||||
deploy: {
|
||||
SimpleStorage: {
|
||||
skipBytecodeCheck: true
|
||||
}
|
||||
}
|
||||
},
|
||||
```
|
||||
|
||||
This becomes useful in cases of private multi-node environments, where we do not want Embark to deploy contracts to the current node when another node on the chain may already have the contract deployed to it.
|
||||
|
||||
More to the point, when using Embark's Quorum plugin in a private multi-node private setup (ie using the [7nodes example](https://github.com/jpmorganchase/quorum-examples/tree/master/examples/7nodes)), we might want to deploy a contract privately between Node 1 and Node 7, for example. In this case, we deploy the contract by connecting Embark to the Node 1 environment we have set up in our blockchain config. Connecting to our Node 7 environment set up in our blockchain config, we should see values for our contracts. However, connecting to other Node environments in our blockchain config (ie Nodes 2 - 6), those contract values should not exist on the node. The only way to ensure that we do not deploy our contracts to Nodes 2 - 6 when they're not meant to exist there, is by setting the `skipBytecodeCheck: true` setting for the contract in the contracts config.
|
||||
|
||||
The downside of this, is that if we perform an `embark reset` (effectively deleting our `chains.json`, and therefore losing track of which contracts we've previously deployed), we have no way to check if our chain has already deployed our contract or not. In this case, Embark will deploy the contracts to the current environment regardless.
