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

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.
