Highly Efficient mining pool designed for Ethash based coins
**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. Testing and bug submissions are still welcome!
- 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)
- 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
**Please clone the project using the branches as per the coin
- V2.0_Eth – Ethereum pool for go version <=1.10
- V2.0_Eth_11 -– Ethereum pool for go version >=1.11
- V2.0_Etc – Ethereum Classicpool for go version <=1.10
- V2.0_Exp – Expanse pool for go version <=1.10
- V2.0_Ubiq – Ubiq pool for go version <=1.10
- V2.0_Pirl – Pirl pool for go version <=1.10
- V2.0_Dbix – Dubai coin pool for go version <=1.10
- V2.0_Soil – Soil Coin pool for go version <=1.10
- V2.0_Mc – Music Coin pool for go version <=1.10
- V2.0_Nuko – Nuko coin - * Not implemented
Dependencies:
- go >= 1.9 but <1.10 ( For 1.11 Refer branches)
- geth or parity
- redis-server >= 2.8.0
- nodejs >= 4 LTS
- nginx
I highly recommend to use Ubuntu 16.04 LTS.
First install go-ethereum.
Clone & compile:
git config --global http.https://gopkg.in.followRedirects true
git clone https://github.com/techievee/ethash-mining-pool.git
<Change the branch>
git pull
cd open-ethereum-pool
make
Install redis-server.
There are 2 front end application.
- One for showing the consolidated view of different pool statistics
- Another for single coin frontend.
You may choose your desired one To show the statistics for one coin (Front end api) : https://github.com/techievee/statistics_api To show the consolidated statistics for all the coins that were implemented : https://github.com/techievee/generalapi
The frontend is a single-page Ember.js application that polls the pool API to render miner stats. Please refer the frontend application Readme.md for more information. Those frontend are not compliant to sammy007 versions
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
endSpace : 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’ sharesSpace : 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
EndSpace : O(N) RunTime : O(N)
Configuration is actually simple, just read it twice and think twice before changing defaults.
