-  /*
-	@desc This function is one of the most important functions in this code
-        In our current implementation, we have support for two events: newBlockHeaders and pendingTransactions
-        When listening to the pendingTransactions, regardless of whether we are using Proof of work or Proof of authority, all of the transactions have the "from" attribute
-        which refers to the ethereum account that triggered the transaction. This "from" attribute always has a valid address
-        The problem comes when we are listening to newBlockHeaders with Proof of authority.
-        When using Proof of work and the newBlockHeaders event is triggered, we get the miner's address in the result through the "miner" property. We then figure out in what
-        container this address is and we flash this container on the frontend.
-        When using Proof of authority, the "miner" attribute always has a value of "0x000000..." which doesn't match with any of the existing accounts or containers. Flashing then fails
-	because account "0x000000..." is not in any container.
-        To be able to get the signer of a certain block we have to use axios to create a jsonrpc request as web3 does not have a direct api to fetch them. For example, in PoW, if i want
-        to fetch all accounts, i can write "web3.eth.accounts", but I cannot write "web3.clique.getSigners" as clique is not available.
-        Documentation states that performing a jsonrpc will solve our issue
-        This function is the one that handles all cases including the PoA edge case that we currently described.
-  
-  	@fix The assumption mentioned above about having the "miner" field always set to 0x00000... when running PoA and listening to the newBlockHeaders event is wrong. In PoA, the "miner"
-        field is true unless a proposal is made. Assuming A proposes that B becomes a new signer on the blockchain, the "miner" property of the block header will be set to B.
-        How could this affect the visualization? We will be flashing a node that we don't want
-        @solution Figure out what consensus was run by the node that added the block (in case we run more than one consensus in our emulator), and run the axios code if we have PoA and newBlockHeaders at the same time instead of checking if 
-        __accountsToContainerMap has the address (this will be true when A proposes B)

+<a name="blockchain-component"></a>
+# Build a Blockchain Component
+
+## A.1 Creating Virtual Blockchain Node
+
+We will create the Blockchain nodes at the Ethereum layer, 
+so each node created is a virtual node so that they can be deployed
+in different emulators.
+
+```python
+# Create the Ethereum layer
+# saveState=True: will set the blockchain folder using `volumes`, 
+# so the blockchain data will be preserved when containers are deleted.
+eth = EthereumService(saveState = True, override=True)
+
+
+# Create POW Ethereum nodes (nodes in this layer are virtual)
+# Default consensus mechanism is POW. 
+e1 = eth.install("eth1").setConsensusMechanism(ConsensusMechanism.POW)
+e2 = eth.install("eth2")
+e3 = eth.install("eth3")
+e4 = eth.install("eth4")
+
+# Create POA Ethereum nodes
+e5 = eth.install("eth5").setConsensusMechanism(ConsensusMechanism.POA)
+e6 = eth.install("eth6").setConsensusMechanism(ConsensusMechanism.POA)
+e7 = eth.install("eth7").setConsensusMechanism(ConsensusMechanism.POA)
+e8 = eth.install("eth8").setConsensusMechanism(ConsensusMechanism.POA)
+```
+
+
+## A.2 Setting a Node as a Bootnode
+
+We can set a node as a bootnode that bootstraps all blockchain nodes.
+If a node is set as a bootnode, it will run a http server that sends 
+its blockchain node url so that the other nodes can connect to it. 
+The default port number of the http server is 8088 and it can be 
+customized. If bootnode does not set to any node, we should specify 
+peer nodes urls manually. 
+
+```python
+# Set bootnode on e1. The other nodes can use these bootnodes to find peers.
+e1.setBootNode(True).setBootNodeHttpPort(8090)
+``` 
+
+## A.3 Creating Accounts
+
+By default, one account will be created per node. In POW Consensus, 
+the account will be created with no balance. In the case of POA Consensus, 
+the account will have 32*pow(10,18) balance as the node will not get sealing
+(mining) rewards in POA. 
+If you want to create additional accounts you can use `createAccount` 
+or `createAccounts` method. Using a `createAccount`, you can create 
+an individual account customizing balance and password. On the other
+hand, using a `createAccounts` method, you create a bulk of accounts 
+that have same amount of balance and a same password.
+
+```python
+# Create more accounts with Balance on e3 and e7
+# Create one account with createAccount() method
+# Create multiple accounts with createAccounts() method
+e3.createAccount(balance= 32 * pow(10,18), password="admin")
+e7.createAccounts(3, balance = 32*pow(10,18), password="admin")
+```
+
+## A.4 Importing Accounts
+
+When you want to reuse an existing account, you can use `importAccount` method.
+
+```python
+# Import account with balance 0 on e2
+e2.importAccount(keyfilePath='./resources/keyfile_to_import', password="admin", balance=0)
+```
 
-## A.1 Automated setup
+## A.5 Setting Geth Command Options
 
-Make sure driver.sh has the executable permission by running `chmod +x driver.sh`
-./driver.sh will automate each of the steps mentioned below.
-If any issue occurs, it would be best to do them manually.
+We use `go-ethereum;geth` software to run blockchains on emulator.
+When the containers are up, they will install `geth` and run it with the command
+which is generated from EthereumService Class. We can customized the
+`geth start command` with the following methods.
+The `base start command` is `geth --datadir /root/.ethereum --identity="NODE_5" --networkid=10 --syncmode full --verbosity=2 --allow-insecure-unlock --port 30303`
 
+- `setNoDiscover()` = --nodiscover
+- `enableGethHttp()` = --http --http.addr 0.0.0.0 --http.port 8545 --http.corsdomain "*" --http.api web3,eth,debug,personal,net,clique
+- `enableGethWs()` = --ws --ws.addr 0.0.0.0 --ws.port 8546 --ws.origins "*" --ws.api web3,eth,debug,personal,net,clique
+- `unlockAccounts()` = --unlock "{accounts}" --password "{accounts_passwords}"
+- `startMiner()` = --mine --miner.threads=1
 
-## A.2 Create the Blockchain Component
+You can also set further options using `setCustomGethCommandOption()` method. 
+The options will append to the `base start command`. 
+
+```python
+# Start mining on e1,e2 and e5,e6
+# To start mine(seal) in POA consensus, the account should be unlocked first. 
+e1.setBootNode(True).setBootNodeHttpPort(8090).startMiner()
+e2.startMiner()
+e5.setBootNode(True).unlockAccounts().startMiner()
+e6.unlockAccounts().startMiner()
+
+# Enable http connection on e3 
+# Set geth http port to 8540 (Default : 8545)
+e3.enableGethHttp().setGethHttpPort(8540)
+
+# Set custom geth command option on e4
+# Possible to enable geth http using setCustomGethCommandOption() method 
+# instead of using enableGethHttp() method
+e4.setCustomGethCommandOption("--http --http.addr 0.0.0.0")
+
+# Enable ws connection on e5 geth
+# Set geth ws port to 8541 (Default : 8546)
+e5.enableGethWs().setGethWsPort(8541)
+
+# Set nodiscover option on e8 geth
+e8.setNoDiscover()
+```
+## A.6 Setting Custom Geth Binary
+
+Occationally, it is needed to set customed `geth` binary instead of the original one
+to conduct experiment. In this case, you can use `setCustomGeth()` method.
+
+```python
+# Set custom geth binary file instead of installing an original file.
+e3.setCustomGeth("./resources/custom_geth")
+```
+
+## A.7 Setting Custom Genesis
+
+If you want to deploy your customed genesis file on a blockchain,
+you can set the customed genesis using the `setGenesis()` method.
+
+```python
+# Set custom genesis on e4 geth
+e4.setGenesis(CustomGenesisFileContent)
+```

-# Visualization
-
-## Build
-- Run either `mini-blockchain-emulator.py` or `nano-blockchain-emulator.py` to generate a bin file
-- Run the `component-blockchain.py`
-- Go to the `emulator` folder
-- Run `dcbuild`
-- Check the section below for the `dcup`
-
-## Notice
-- Due to a bug in docker, you might not be able to bring the containers up
-- We provide a file called `lazy_start.sh` which brings up containers gradually
-- Copy the file in the `emulator` folder and run it after executing the `dcbuild` alias
-
-## Concept
-- The visualization is built on a plugin-type architecture.
-- We can now create a new plugin for different projects that fetch data from the emulator and passes it to the frontend
-
-## Client architecture
-- The client is divided into two project, the frontend, and the backend
-- Both projects use typescript as a base language
-- Both projects are technically node projects where we can install external npm packages
-- The frontend is clueless about the processing that happens on the backend.
-- The data received on the frontend is in no way an indicator of which plugin is running
-
-## Frontend
-- The three main npm packages for visualization are the `vis-data`, `vis-network`, and `vis-util`
-- We can generate the emulator's graph using these libraries
-
-## Backend
-- The backend is built as a node express server
-- You can send POST and GET requests to the server depending on what routes are created
-- You can also create a websocket connection from the frontend to one of the websocket routes
-
-## Plugin architecture
-
-## Frontend
-
-- Most of the work was added to the `frontend/src/map/ui.ts` file
-- The bulk of the work happens when the user clicks on the `Blockchain` tab above the search bar
-- For all plugins, we will make use of two APIs provided on the backend server to be able to fetch data
-- To create a new plugin, call
-```
-    await this._datasource.initPlugin(type)
-```
-- This function sends a POST request to `/api/v1/plugin/:type/init` on the server side
-- The type must match one of the types in `backend/src/plugin/PluginEnum.ts`
-- Once this is called on the frontend, a new manager plugin of type `type` is created on the server side
-- After that, we need create a WebSocket connection with the server
-- The socket is created in this way: 
-```
-    const url = 'ws://localhost:8080/api/v1/plugin/${type}/command/'; 
-    const ws = new WebSocket(url);
-```
-- This connection is the one which we will make use of to pass data to/from frontend/backend
-- To get messages from the backend, we add an `onmessage` listener by writing 
-```
-    ws.onmessage = (event) => {...}
-```
-- To send data to the backend, we use the function
-```
-    ws.send(JSON.stringify(...))
-```
-- One example of data sent from the frontend to the backend is 
-```
-    {
-    	command: "start newBlockHeaders xyz"
-    }
-```
-
-## Backend
-
-- There are two parts to cover on the backend: the routes, and the plugin architecture
-
-### Routes
-- The routes are added in `/backend/src/api/v1/main.ts`
-- We created two new express routes which will be used by all future plugins
-- The first one is reached by doing a POST request to `/api/v1/plugin/:type/init`. This is the route that creates a new plugin on the backend side. This plugin is the one that will fetch data from the emulator's docker containers
-- To receive data from the plugin instance itself, we add
-```
-    instantiated_plugins[type].onMessage(function(data) {...})
-```
-- The second express route is reached by creating a new socket connection to `ap1/v1//plugin/:type/command/`. In this route, we set a `message` listener to get data from the frontend by writing
-```
-    running_ws[type].on('message', (message) => {...})
-```
-- The data received by the frontend should be an object that has the `command` property. This `command` property is a string of the from `<action> <filter> <params>` where the `<action>` takes the values of `start` or `stop`, the `<filter>` takes the values of the events you want listen to from the emulator (plugin specific), and the `params` field is optional
-- Now that the socket connection received the full command from the frontend, we can run our plugin code depending on the `<action>` provided
-- To send data to the frontend, we use the
-```
-    running_ws[type].send(JSON.stringify(...))
-```
-
-
-### Plugin architecture
-- On the backend side, when the POST request is sent to `/api/v1/plugin/:type/init`, we create a new plugin of type `BasePlugin`
-- When we create a new `BasePlugin`, we need to specify the `type` of the plugin as parameter. For blockchain, the type is equal to `1`
-- The type must match one of the types in `backend/src/plugin/PluginEnum.ts` as these are the currently supported plugins
-- Under the hood, this class creates a new `EventEmitter` which we can use to listen to new messages
-- The `onMessage` function that we mentioned above makes use of the `EventEmitter` to get data from the plugin itself
-- To create a new plugin, your class has to implement the `PluginInterface` to add the proper functions. You also need to add your class inside `BasePlugin.ts`
-- You plugin is the one that will fetch data from the emulator and pass it to the `onMessage` inside the websocket route
-
-![](./images/plugin-architecture.png)
-
-### Blockchain plugin
-- The `BlockchainPlugin.ts` implements `PluginInterface.ts`
-- This plugin is the one that connects to the Ethereum nodes using Web3 and fetches the data from the emulator
-- When the user sends `start newBlockHeaders xyz`, we use Web3 to attach event listeners inside the Ethereum nodes.
-- To connect to the Ethereum nodes using web3, we use
-```
-const web3 = new Web3(new Web3.providers.WebsocketProvider(ws://${ip}:8546, {
-        clientConfig: {
-                // Useful to keep a connection alive
-                keepalive: true,
-                keepaliveInterval: 60000 // ms
-        },
-      }));
-```
-- Our ethereum nodes expose port 8546 for external websocket connections. We do this using the `geth` ethereum client.
-- The data received by web3 includes new blocks that are mined, and new trddansactions that are performed.
-- To listen to `newBlockHeaders`, we use:
-```
-    const subscription = web3.eth.subscribe("newBlockHeaders", (error, result) => {...})
-```
-- The Ethereum nodes will now start sending to our Plugin instance data which we will relay using the `onMessage` and then uses this command to send data to the frontend 
-``` 
-    running_ws[type].send(JSON.stringify(...)) 
-``` 
-- When the user sends `stop newBlockHeaders`, we use
-```
-    subscription.unsubscribe((error, success) => {...})
-```
-- The Ethereum nodes will now stop sending us data.
-
-
-### Data
-
-- The data sent to the frontend is in no way representative of what plugin is running on the backend.
-- The data is only relevant to the visualization itself.
-- The data is structured in the following way: 
-``` 
-    {
-      eventType: event_type.data,
-      timestamp: Date.now(),
-      status: data.status, // success or error
-      containerId: data.containerId, // node to highlight
-      data: data.data, // configs for vis-network library to highligh nodes
-    }
-```
-- `data.data` looks like:
-```
-    {
-            borderWidth: 4,
-            color: {
-                    background: "purple",
-                    border: "purple"
-            }
-    }
-```
-
-### docker-compose.yml
-
-- Since the client is built and brought up separately from the emulator, we need to do 2 configurations for it to be connected to the network
-- The first configuration requires you to modify the `docker-compose.yml` inside the client folder
-- We need to add the `networks` keyword, both inside the service and at the top level. Below is an example of how to do that.
-- After running the emulator, you need to find any network to which an ethereum node is connected
-- To do so, first use the `docker ps | grep Ethereum` command to find the Ethereum containers
-- After that, locate any ip address such as `10.151.0.77`. 151 represents the ASN, and 0 represents the network
-- In the docker-compose.yml below, you will replace `net_3_net3` by `net_151_net0`. In addition to that, we use the word `emulator` when setting up the networks (`emulator_net_3_net3`), this represents the folder in which you built your emulator.
-- You can now `dcbuild` and `dcup` the client folder.
-- Once this is done we will need to change the default routing of the container.
-- Start by getting shell access to the client container using the `docksh` alias, 
-- To see the current ip table, type `ip route show`. You will see an entry for a `default` route
-- Delete this default route using `ip route del default` then add a new default route using `ip route add default via <ip>` where <ip> is the ip of the BGP router in the map. Any packet that doesn't match other routing rules will be routed by default to this new ip that you provide.
-- Go to the map, select the search tab, and look for your ASN, in this case `151`. In our convention, all of the nodes in the same network are of the same color. Find the BGP router of the same color, click on it, and copy its ip address from the side panel on the map. This will be the <ip> mentioned above.

-# Unit testing for EthereumSevice
-
-## Overview
-
-This folder contains the all unit testing cases for EthereumService using library [unittest](https://docs.python.org/3/library/unittest.html), a unit testing included in python. This unit testing will going to build and run the container for unit testing by asserting the output of command run on specific container.
-
-This unit testing is an example to show how to write the unit test cases for seed-emulator.
-
-## How to run
-
-### Run all test cases
-
-Before running the testing, you should make sure loading the environment of emulator.
-
-```sh
-source development.env
-```
-
-1. Run all test cases
-
-This unit testing have a loader to load all the ethereum service unit testing cases.
-
-```sh
-python3 loader_ethereum.py
-```
-
-Then wait some time for testing, it may need half an hours to run all the case depend on the computer.
-
-### Run single test cases
-
-For example, we can run single test case `test_Run_POA`. 
-
-1. Go to test cases folder
-
-```sh
-cd cases
-```
-
-2. Run the test case
-
-```sh
-python3 test_Run_POA.py
-```
-
-Then wait some time for testing, it may need 10 minutes to run this case depend on the computer.
-
-## Folder Structure Explain
-
-In side this case, there are two essential folders. 
-
-`cases` for test cases python code.
-
-`resources` for the resource for a single test case, normally it contains python code that defines the network for testing and some bash scripts to build and run the containers for testing. 
-
-## How to write a Test Case
-
-We are highly recommended to read the unittest document and learn the base concepts before starting reading the test case.
-
-You could look at a well-commented test case example `cases/test_Run_POA.py` to learn how to write a test case.
-
-## Test Cases
-
-- test_EthAccount
-
-    This test case test the EthAccount class in `Ethereum Service`. It will test do the methods work correctly, especially create account and import account.
-
-- test_Genesis
-    
-    This test case test the Genesis class in `Ethereum Service`. It will test do the methods work correctly, especially for POA and POW genesis file content output.
-
-- test_Run_POA
-
-    This test case test a ethereum network only using Proof-Of-Authority consensus.
-
-- test_Run_POW
-
-    This test case test a ethereum network only using Proof-Of-Work consensus.
-
-- test_Run_POA
-
-    This test case test a ethereum network using both Proof-Of-Authority and Proof-Of-Work consensus.
