merged-pooler

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 :)

Notice

I am trying to make this useable software. On my list of up-front todos:

• Multiple PoWAUX coins on each main chain
• Profit Switching

Frontend and payment enhancements will be a separate repo. (Insert repo URL when created)

Why

The software that I forked was a wonderful beginning that never came to fruition. I hope to bring Node stratum into the mainstream of merged mining.

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)
• Patience :)

Example Usage

Install as a node module by cloning repository

git clone https://github.com/sigwo/node-merged-pool
cd node-merged-pool
npm update

Note to self: Add actual instructions here.

Module usage

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