Open-ethereum-pool

Highly Efficient mining pool designed for ETC coin

Features

**This pool is reegineered from sammy007 open-ethereum-pool for efficiency and for better payment algorithm. This software is functional and tested and implemented in big Mining farms!

• Support for HTTP, SSL, Stratum, Stratum+SSL mining
• Detailed block stats with luck percentage and full reward
• Failover node instances: high availability built in (Any number of full nodes can be added to the configurations)
• Modern beautiful Ember.js frontend for Individual coin statistics vs consolidated coin statistics
• Separate stats for workers: can highlight timed-out workers so miners can perform maintenance of rigs
• JSON-API for statistics, (Looking for contributor to build app for the pool)
• Dynamic PPLNS block reward (*New)

How it is different from sammy007 version

• Reengineered most of the code for efficiency and Scaling
• New Dynamic PPLNS Reward System
• Integration with the Exchange to get real-time conversion between crypto and fiat.
• The Network fees can be configured to be withheld for every transfers.
• The gas can be set as Auto and made to deduct automatically or can be fixed by the pool operator
• Many parameters configurable using config file
• Nicehash support *Not tested
• SSL Support built-in
• Very attractive frontend with more detailed statistics

Building on Linux

Dependencies:

apt install software-properties-common unzip nginx tor pcscd pcsc-tools git curl htop mc unrar screen

I highly recommend to use Ubuntu 18.04.4 LTS.

Geth setup:

sudo su
mkdir /pool && cd /pool
wget https://github.com/multi-geth/multi-geth/releases/download/v1.9.7/multi-geth-linux.zip
unzip multi-geth-linux.zip
ln -s /pool/geth /usr/bin/geth
chmod ugo+x /usr/bin/geth

geth --classic account new
geth --classic account list

example output:

Public address of the key: 0xa9c96bff41FFAFb6bE8c2990c0CF4F3b220aaEaa Path of the secret key file: /root/.ethereum/classic/keystore/UTC--2020-03-11T22-03-07.512690005Z--a9c96bff41ffafb6be8c2990c0cf4f3b220aaeaa

Create geth start script:

nano /pool/start_geth.sh

#!/bin/bash
screen -S server geth --classic --rpc --maxpeers 75 --syncmode "fast" --rpcapi "eth,net,web3,personal" --etherbase "YOUR_WALLET" --cache=12288 --mine --unlock "YOUR_WALLET" --allow-insecure-unlock --password /pool/pwd

Enter wallet password to the file:

nano /pool/pwd

chmod +x /pool/start_geth.sh

Start blockchain sync:

./start_geth.sh

In new console window run this commands:

sudo su
cd /pool
git config --global http.https://gopkg.in.followRedirects true
git clone https://github.com/notminerproduction/open-ethereum-pool.git
cd open-ethereum-pool
chmod +x ./build/env.sh
add-apt-repository ppa:longsleep/golang-backports
apt update
apt install golang-go
make
add-apt-repository ppa:chris-lea/redis-server
apt update
apt install redis-server
systemctl enable redis-server.service && systemctl stop redis-server.service && systemctl start redis-server.service

Building Frontend

cd www/

Change 192.168.0.200 to your IP or DNS in file environment.js:

nano config/environment.js

Then run this commands:

sudo npm install -g ember-cli@2.9.1
sudo npm install -g bower
sudo npm install fsevents@latest -f --save-optional
sudo npm install intl-format-cache@4.2.22

DPPLNS ALGORITHM (NEW)

The algorithm explanation is as follows

• CALCULATING THE LAST N VALUE

Check whether blockchainnode present
If present
	Calulcate the current network difficulty
	Calulate the network difficulty *2
	Calculate the N value by (2* Network difficulty)/ Share difficulty
 	Set the last N value in the statistics hash key
Else
	Fix the predetermined standard ‘N’ value from the block chain	

Space : O(1) RunTime : O(1)

• ADJUSTING THE ‘N’ SHARES

Get the current last N value from the lastNshares Hash
Get the current count of lastNshares list
If lastNShare< count
	Loop(count - lastNshare )
		Pop lastNShare
		Decrement the miners share count from the lastN value
    		Decrement the total shares count
       end

Space : O(1) RunTime : O(N)

• NEW SHARE SUBMISSION

Push the value of miners address into the last shares list
Increment the current round shares by 1
Increment the round shares value by 1
Increment the miners shares by 1
Check if new block found
If found
	Run the New block function
Else
Adjust the value of ‘N’ shares

Space : O(1) RunTime : O(1)

• REWARD CALUCLATION USING DPPLNS

Loop(lastNshare )
		Get the miners address from list
Increment the local miners current round share 
       End
Loop(miners of current round)
		Percentage= minersshare / current round share
End

Space : O(N) RunTime : O(N)

Configuration Documentation- Applies to all brnanches

Configuration is actually simple, just read it twice and think twice before changing defaults.
