An extremely efficient, highly scalable, all-in-one, easy to setup cryptocurrency mining pool
This repo will serve as an open source multipool. Multipool capabilities are in alpha testing in this version. This will give the ability to utilize NOMP with merged capabilities but NO merged coin payouts. ONLY the main chain coins will payout and calculate correctly at the moment.

This portal is an extremely efficient, highly scalable, all-in-one, easy to setup cryptocurrency mining pool written in Node.js. It contains a merged stratum pool server; reward/payment/share processor for multipooling; and an (in progress) responsive user-friendly front-end website featuring mining instructions, in-depth live statistics, and an admin center.
This is beta software. All of the following are things that can change and break an existing setup: functionality of any feature,
structure of configuration files and structure of redis data. If you use this software in production then DO NOT pull new code straight into
production usage because it can and often will break your setup and require you to tweak things like config files or redis data, among other things.
For the pool server it uses the highly efficient node-merged-pool module which supports vardiff, POW & POS, transaction messages, anti-DDoS, IP banning, several hashing algorithms.
This implementation is merged mining capable. You may add AUXPoW coins to the main chain configurations. At this point, the merged coins do everything EXCEPT display on the site or payout automatically. Shares, blocks, and coinbase transactions complete as planned.
Multicoin ability - this software was built from the ground up to run with multiple coins simultaneously (which can have different properties and hashing algorithms). It can be used to create a pool for a single coin or for multiple coins at once. The pools use clustering to load balance across multiple CPU cores.
For reward/payment processing, shares are inserted into Redis (a fast NoSQL key/value store). The PROP (proportional) reward system is used with Redis Transactions for secure and super speedy payouts. There is zero risk to the pool operator. Shares from rounds resulting in orphaned blocks will be merged into share in the current round so that each and every share will be rewarded.
This portal does not will never have user accounts/logins/registrations. Instead, miners simply use their coin address for stratum authentication.
Coin-switching ports using coin-networks and crypto-exchange APIs to detect profitability.
Past MPOS functionality is no longer available/working. Signing up and mining pools don't mix. See PR #15.
Basic multipooling features included, but NOT enabled by default. You must follow the README in the multipool folder. More updates WILL happen in the multipool options and will stay open source.
UNOMP has some implicit security advantages for pool operators and miners:
UNOMP API - Used by the website to display stats and information about the pool(s) on the portal's front-end website. Mostly complete.
Integration of addie.cc usernames for multiple payout type without using a public address that may/may not work with the coin (still not 100% committed yet, see Feature #7)
Upgrade codebase to operate in node v 0.12. Complete. If you run into problems, please open an issue.
OPTIONAL: sudo npm install posix, but you will have to start the pool sudo node init.js
Those are legitimate requirements. If you use old versions of Node.js or Redis that may come with your system package manager then you will have problems. Follow the linked instructions to get the last stable versions.
Redis security warning: be sure firewall access to redis - an easy way is to
include bind 127.0.0.1 in your redis.conf file. Also it's a good idea to learn about and understand software that
you are using - a good place to start with redis is data persistence.
Redis server may require a password, this is done using the requirepass directive in the redis configuration file. By default config.json contains blank "" - means disabled redis auth, to set any password just put "redispass" in quotes.
Follow the build/install instructions for your coin daemon. Your coin.conf file should end up looking something like this:
daemon=1
rpcuser=litecoinrpc
rpcpassword=securepassword
rpcport=19332
For redundancy, its recommended to have at least two daemon instances running in case one drops out-of-sync or offline,
all instances will be polled for block/transaction updates and be used for submitting blocks. Creating a backup daemon
involves spawning a daemon using the -datadir=/backup command-line argument which creates a new daemon instance with
it's own config directory and coin.conf file. Learn about the daemon, how to use it and how it works if you want to be
a good pool operator. For starters be sure to read:
Clone the repository and run npm update for all the dependencies to be installed:

You can create as many of these pool config files as you want (such as one pool per coin you which to operate). If you are creating multiple pools, ensure that they have unique stratum ports.
For more information on these configuration options see the pool module documentation
config.json set the port and password for blockNotifyListenerblocknotify command to use:node [path to cli.js] [coin name in config] [block hash symbol]
Example: inside dogecoin.conf add the line
blocknotify=node /home/unomp/scripts/cli.js blocknotify dogecoin %s
Alternatively, you can use a more efficient block notify script written in pure C. Build and usage instructions are commented in scripts/blocknotify.c.
node init.js
When updating UNOMP to the latest code its important to not only git pull the latest from this repo, but to also update
the merged-pooler and node-multi-hashing modules, and any config files that may have been changed.
git pull to get the latest UNOMP code.node_modules directory with rm -r node_modules.npm update to force updating/reinstalling of the dependencies.config.json and pool_configs/coin.json configurations to the latest example ones in this repo or the ones in the setup instructions where each config field is explained. You may need to modify or add any new changes.Below is my donation address. The original credits are listed here because I felt scammy if I totally removed them.
