High performance Stratum poolserver in Node.js. One instance of this software can startup and manage multiple coin pools, each with their own daemon and stratum ports :)

This software has been modefied for merged mining. It is still in development.

Notice

This is a module for Node.js that will do nothing on its own. Unless you're a Node.js developer who would like to handle stratum authentication and raw share data then this module will not be of use to you.

Why

This server was built to be more efficient and easier to setup, maintain and scale than existing stratum poolservers which are written in python. Compared to the spaghetti state of the latest stratum-mining python server, this software should also have a lower barrier to entry for other developers to fork and add features or fix bugs.

Features

• Merged Mining Support
• Daemon RPC interface
• Stratum TCP socket server
• Block template / job manager
• P2P to get block notifications as peer node
• Optimized generation transaction building
• Connecting to multiple daemons for redundancy
• Process share submissions
• Session managing for purging DDoS/flood initiated zombie workers
• Auto ban IPs that are flooding with invalid shares
• POW (proof-of-work) & POS (proof-of-stake) support
• Transaction messages support
• Vardiff (variable difficulty / share limiter)
• When started with a coin daemon that hasn't finished syncing to the network it shows the blockchain download progress and initializes once synced

Hashing algorithms supported:

• ✓ SHA256 (Bitcoin, Freicoin, Peercoin/PPCoin, Terracoin, etc..)
• ✓ Scrypt (Litecoin, Dogecoin, Feathercoin, etc..)
• ✓ Scrypt-Jane (YaCoin, CopperBars, Pennies, Tickets, etc..)
• ✓ Scrypt-N (Vertcoin [VTC])
• ✓ Quark (Quarkcoin [QRK])
• ✓ X11 (Darkcoin [DRK], Hirocoin, Limecoin)
• ✓ X13 (MaruCoin, BoostCoin)
• ✓ NIST5 (Talkcoin)
• ✓ Keccak (Maxcoin [MAX], HelixCoin, CryptoMeth, Galleon, 365coin, Slothcoin, BitcointalkCoin)
• ✓ Skein (Skeincoin [SKC])
• ✓ Groestl (Groestlcoin [GRS])

May be working (needs additional testing):

• ? Blake (Blakecoin [BLC])
• ? Fugue (Fuguecoin [FC])
• ? Qubit (Qubitcoin [Q2C], Myriadcoin [MYR])
• ? SHAvite-3 (INKcoin [INK])

Not working currently:

• Groestl - for Myriadcoin
• Keccak - for eCoin & Copperlark
• Hefty1 (Heavycoin [HVC])

Requirements

• node v0.10+
• coin daemon for primay and auxillery coins (preferably one with a relatively updated API and not some crapcoin :p)

Example Usage

Install as a node module by cloning repository

git clone https://github.com/KillerByte/node-stratum-pool node_modules/stratum-pool
npm update

Module usage

Please see the included example.js file for more information. This section should be expanded soon.
