eIquidus

v1.99.0

Written in node.js and mongodb, eIquidus is the most stable, secure, customizable and feature-rich open-source block explorer with support for virtually any altcoin that implements some form of the Bitcoin RPC API protocol. Originally built for the Exor blockchain, eIquidus has since grown into a fully-featured explorer with a focus on stability and security at its core. All features from the original iquidus explorer are included here along with many new ideas from other iquidus forks, and an absolute ton of new custom changes and bug fixes that were developed specifically for eIquidus.

Installation

Full Setup Guide

While we do not yet have our own step-by-step setup instructions, there are a few well-written guides out there already that detail how to set up and install the original iquidus explorer. Because the setup process for iquidus is more-or-less identical to eIquidus at this moment in time (making changes to settings.json is probably the biggest difference although we have helpful comments for each setting), here are some of the more complete guides that may be useful for anyone who needs more detailed instructions than are provided in the Quick Install Instructions:

  1. Iquidus Block Explorer Setup Guide
  2. Node and Iquidus Explorer Setup for Dummies
  3. Iquidus Block Explorer Guide

Quick Install Instructions

Pre-Install

The following prerequisites must be installed before using the explorer:

Database Setup

Open the MongoDB cli:

mongo

Select database:

NOTE: explorerdb is the name of the database where you will be storing local explorer data. You can change this to any name you want, but you must make sure that you set the same name in the settings.json file for the dbsettings.database setting.

use explorerdb

Create a new user with read/write access:

db.createUser( { user: "eiquidus", pwd: "Nd^p2d77ceBX!L", roles: [ "readWrite" ] } )
Download Source Code
git clone https://github.com/team-exor/eiquidus explorer
Install Node Modules
cd explorer && npm install --production
Configure Explorer Settings
cp ./settings.json.template ./settings.json

Make required changes in settings.json

Start/Stop the Explorer

Start Explorer (Use for Testing)

You can launch the explorer in a terminal window that will output all warnings and error msgs with one of the following cmds (be sure to run from within the explorer directory):

npm start

or (useful for crontab):

npm run prestart && /path/to/node --stack-size=10000 ./bin/cluster

NOTE: mongod must be running to start the explorer.

The explorer defaults to cluster mode by forking an instance of its process to each cpu core, which results in increased performance and stability. Load balancing gets automatically taken care of and any instances that for some reason die, will be restarted automatically. If desired, a single instance can be launched with:

npm run start-instance

or (useful for crontab):

npm run prestart && /path/to/node --stack-size=10000 ./bin/instance

Stop Explorer (Use for Testing)

To stop the explorer running with npm start you can end the process with the key combination CTRL+C in the terminal that is running the explorer, or from another terminal you can use one of the following cmds (be sure to run from within the explorer directory):

npm stop

or (useful for crontab):

sh ./scripts/stop_explorer.sh

Start Explorer Using PM2 (Recommended for Production)

PM2 is a process manager for Node.js applications with a built-in load balancer that allows you to always keep the explorer alive and running even if it crashes. Once you have configured the explorer to work properly in a production environment, it is recommended to use PM2 to start and stop the explorer instead of npm start and npm stop to keep the explorer constantly running without the need to always keep a terminal window open.

You can start the explorer using PM2 with one of the following terminal cmds (be sure to run from within the explorer directory):

npm run start-pm2

or (useful for crontab):

npm run prestart "pm2" && /path/to/pm2 start ./bin/instance -i 0 --node-args="--stack-size=10000"

NOTE: Use the following cmd to find the install path for PM2:

which pm2

Start Explorer Using PM2 and Log Viewer

Alternatively, you can start the explorer using PM2 and automatically open the log viewer which will allow for viewing all warnings and error msgs as they come up by using one of the following terminal cmds (be sure to run from within the explorer directory):

npm run start-pm2-debug

or (useful for crontab):

npm run prestart "pm2" && /path/to/pm2 start ./bin/instance -i 0 --node-args="--stack-size=10000" && /path/to/pm2 logs

Stop Explorer Using PM2 (Recommended for Production)

To stop the explorer when it is running via PM2 you can use one of the following terminal cmds (be sure to run from within the explorer directory):

npm run stop-pm2

or (useful for crontab):

/path/to/pm2 stop ./bin/instance

Start Explorer Using Forever (Alternate Production Option)

Forever is an alternative to PM2 which is another useful Node.js module that is used to always keep the explorer alive and running even if the explorer crashes or stops. Once you have configured the explorer to work properly in a production environment, forever can be used as an alternative to PM2 to start and stop the explorer instead of npm start and npm stop to keep the explorer constantly running without the need to always keep a terminal window open.

You can start the explorer using forever with one of the following terminal cmds (be sure to run from within the explorer directory):

npm run start-forever

or (useful for crontab):

npm run prestart && /path/to/node /path/to/forever start ./bin/cluster

NOTE: Use the following cmd to find the install path for forever:

which forever

Stop Explorer Using Forever (Alternate Production Option)

To stop the explorer when it is running via forever you can use one of the following terminal cmds (be sure to run from within the explorer directory):

npm run stop-forever

or (useful for crontab):

/path/to/node /path/to/forever stop ./bin/cluster

Syncing Databases with the Blockchain

sync.sh (located in scripts/) is used for updating the local databases. This script must be called from the explorers root directory.

Usage: scripts/sync.sh /path/to/node [mode]

Mode: (required)
update           Updates index from last sync to current block
check            Checks index for (and adds) any missing transactions/addresses
reindex          Clears index then resyncs from genesis to current block
reindex-rich     Clears and recreates the richlist data
reindex-txcount  Rescan and flatten the tx count value for faster access
reindex-last     Rescan and flatten the last blockindex value for faster access
market           Updates market summaries, orderbooks, trade history + charts
peers            Updates peer info based on local wallet connections
masternodes      Updates the list of active masternodes on the network

Notes:
- 'current block' is the latest created block when script is executed.
- The market + peers databases only support (& defaults to) reindex mode.
- If check mode finds missing data(ignoring new data since last sync),
  index_timeout in settings.json is set too low.

It is recommended to have this script launched via a cronjob at 1+ min intervals.

Sample Crontab

Example crontab; update index every minute, market data every 2 minutes, peers and masternodes every 5 minutes

*/1 * * * * /path/to/explorer/scripts/sync.sh /path/to/node update > /dev/null 2>&1
*/2 * * * * /path/to/explorer/scripts/sync.sh /path/to/node market > /dev/null 2>&1
*/5 * * * * /path/to/explorer/scripts/sync.sh /path/to/node peers > /dev/null 2>&1
*/5 * * * * /path/to/explorer/scripts/sync.sh /path/to/node masternodes > /dev/null 2>&1

Wallet Settings

The wallet connected to eIquidus must be running with the following flags:

-daemon -txindex

You may either call your coins daemon using this syntax:

coind -daemon -txindex

or else you can add the settings to your coins config file (recommended):

daemon=1
txindex=1

Run Express Webserver on Port 80

A typical webserver binds to port 80 to serve webpages over the http protocol, but the Express webserver cannot do this by default unless it is given root permissions, which isn't recommended for security reasons. Instead, there are two recommended workarounds to achieve the same end result:

NOTE: Be sure to allow port 80 through any firewalls you may have configured or the explorer website may not be accessible remotely.

Use Setcap to Safely Grant User Permissions

  1. You can use the setcap command to change the capabilities of the node binary file to specifically allow the Express webserver to bind to a port less than 1024 (this one-time cmd requires root privileges):
sudo setcap cap_net_bind_service=+ep `readlink -f \`which node\``
  1. Open the settings.json file and change the webserver.port setting to a value of 80. Save the change and restart the explorer.

You should now be able to browse to the explorer by IP address or domain name without the need for specifying the 3001 port any longer.

Use Another Webserver as a Reverse Proxy

A few steps are involved in setting up another webserver that can bind to port 80 and forward all incoming traffic to the eIquidus node.js app. Any commercial webserver can be used to create the reverse proxy, but in this case, Nginx will be used as an example:

  1. Install Nginx with the following terminal cmd:
sudo apt-get install nginx
  1. Remove the default configuration file:
sudo rm /etc/nginx/sites-enabled/default
  1. Create a new file in /etc/nginx/sites-available/ called node and open it with the nano text editor:
sudo nano /etc/nginx/sites-available/node
  1. Paste the following code in the file and make sure to change example.com to your domain or IP address, and change port 3001 on the proxy_pass line to the port # you have configured for the webserver.port setting in the settings.json file. When done editing, press CTRL+X, then Y (for yes to save) and then ENTER to finish saving the changes to the config file:
server {
    listen 80;
    server_name example.com;

    location / {
        proxy_set_header   X-Forwarded-For $remote_addr;
        proxy_set_header   Host $http_host;
        proxy_pass         "http://127.0.0.1:3001";
    }
}
  1. Create a new symbolic link for the Nginx configuration file that was just created and link it to the /etc/nginx/sites-enabled directory:
sudo ln -s /etc/nginx/sites-available/node /etc/nginx/sites-enabled/node
  1. Restart Nginx to apply the configuration changes:
sudo service nginx restart
  1. Nginx will now forward all incoming requests to eIquidus and after restarting the explorer it should be browsable via http://example.com without the need for the http://example.com:3001 port any longer.

TLS/SSL Support

Similar to the problem with binding to port 80, a typical webserver binds to port 443 to serve webpages over the https protocol, but the Express webserver cannot do this by default unless it is given root permissions, which isn't recommended for security reasons. Instead, there are two recommended workarounds to achieve the same end result: Manually Link TLS/SSL Certificates to the Explorer or Use Nginx as a Reverse Proxy.

NOTE: Be sure to allow port 443 through any firewalls you may have configured or the explorer website may not be accessible remotely.

Prerequisites

There are a few common steps that must be completed before TLS/SSL certificates can be generated:

  1. Install snapd:
sudo apt install snapd
  1. Ensure that snapd is up to date:
sudo snap install core; sudo snap refresh core
  1. Install certbot (full install instructions for different operating systems and configurations can be found here: https://certbot.eff.org/instructions):
sudo snap install --classic certbot
  1. Prepare the certbot command:
sudo ln -s /snap/bin/certbot /usr/bin/certbot

Manually Link TLS/SSL Certificates to the Explorer

Follow the steps below to configure the Express webserver for use with TLS/SSL:

  1. If you haven't already done so, run the setcap cmd from the Use Setcap to Safely Grant User Permissions Instructions which will allow node.js to bind to port 443 without needing root permissions.

  2. There are different options for generating a valid TLS/SSL certificate, but in this case it is assumed that you do not have another webserver running on port 80 and therefore the standalone install method will be used. If you do have a webserver running, this cmd will fail unless you temporarily stop the webserver before continuing:

sudo certbot certonly --standalone

Certbot will ask a few simple questions and generate the necessary TLS/SSL certificate files for your domain. It will also install the necessary files to automatically renew the certificates when they are about to expire, so you shouldn't need to do anything special to keep them up to date.

  1. Once the TLS/SSL certificates are generated, you will need to grant permission to non-root users with the following commands:
sudo chmod -R 755 /etc/letsencrypt/live/
sudo chmod -R 755 /etc/letsencrypt/archive/
  1. The last step is to enable TLS in the explorer's settings.json file and specify the paths to the 3 main certificate files that you just generated. Example:
  "webserver": {
    "port": 80,
    "tls": {
      "enabled": true,
      "port": 443,
      "cert_file": "/etc/letsencrypt/live/example.com/cert.pem",
      "chain_file": "/etc/letsencrypt/live/example.com/chain.pem",
      "key_file": "/etc/letsencrypt/live/example.com/privkey.pem"
    },
    "cors": {
      "enabled": false,
      "corsorigin": "*"
    }
  },

Ensure that webserver.tls.enabled = true and that you specify the exact path to the webserver.tls.cert_file, webserver.tls.chain_file and webserver.tls.key_file files by changing example.com to the domain name that you just generated TLS/SSL certificates for.

  1. If all went well, you should now be able to start up the explorer and browse to it using a secure https connection like https://example.com.

Use Nginx as a Reverse Proxy

  1. If you haven't already done so, first follow through the Use Another Webserver as a Reverse Proxy Instructions and then continue with step #2 below.

  2. Generate a new TLS/SSL certificate via certbot which will automatically edit your Nginx configuration files and enable https at the same time:

sudo certbot --nginx

Certbot will ask a few simple questions and generate the necessary TLS/SSL certificate files for your domain and link them to Nginx. It will also install the necessary files to automatically renew the certificates when they are about to expire, so you shouldn't need to do anything special to keep them up to date.

  1. If all went well, you should now be able to start up the explorer and browse to it using a secure https connection like https://example.com.

CORS Support

eIquidus has basic CORS support which is useful to prevent other sites from consuming public APIs while still allowing specific websites whitelisted access.

What is CORS?

CORS description taken from MaxCDN One

To prevent websites from tampering with each other, web browsers implement a security measure known as the same-origin policy. The same-origin policy lets resources (such as JavaScript) interact with resources from the same domain, but not with resources from a different domain. This provides security for the user by preventing abuse, such as running a script that reads the password field on a secure website.

In cases where cross-domain scripting is desired, CORS allows web developers to work around the same-origin policy. CORS adds HTTP headers which instruct web browsers on how to use and manage cross-domain content. The browser then allows or denies access to the content based on its security configuration.

How to Benefit From Using CORS?

You must first set up CORS in eIquidus by editing the settings.json file and setting the value for webserver.cors.enabled to true.

  "webserver": {
    "cors": {
      "enabled": true,

The webserver.cors.corsorigin setting defaults to "*" which allows all requests from any origin. Keeping this setting at "*" can lead to abuse and is not recommended. Therefore, you should change the webserver.cors.corsorigin setting to an external origin that you control, as seen in the following example:

  "webserver": {
    "cors": {
      "enabled": true,
      "corsorigin": "http://example.com"

The above example would allow sharing of resources from eIquidus for all data requests coming from the example.com domain, while all requests coming from any other domain would be rejected as per normal.

Below is an example of a simple javascript call using jQuery that could be used on your example.com website to return the current block count from eIquidus:

jQuery(document).ready(function($) {
  $.ajax({
    type: "GET",
    url: "http://your-eiquidus-url/api/getblockcount",
    cache: false
  }).done(function (data) {
    alert(data);
  });
});

Useful Scripts

Backup Database Script

Make a complete backup of an eIquidus mongo database collection and save to compressed tar.gz file. Please note that you must ensure that the explorer is NOT running at the time of backup to prevent corrupting the backup data. The following backup scenarios are supported:

Backup Database (No filename specified)

sh scripts/create_backup.sh: Backs up to the explorer/backups directory by default with the current date as the filename in the format yyyy-MMM-dd.tar.gz

Backup Database (Partial filename specified)

sh scripts/create_backup.sh test: Backs up the the explorer/backups directory by default with the filename test.tar.gz

Backup Database (Full filename specified)

node --v8-options | grep -B0 -A1 stack-size

To run a sync with a larger stack size launch with:

node --stack-size=[SIZE] scripts/sync.js index update

Where [SIZE] is an integer higher than the default.

note: SIZE will depend on which blockchain you are using, you may need to play around a bit to find an optimal setting
