Title: Stratum Pool Server [Node.js] (supports POS/POW, SHA/Scrypt/Quark/X11, Vardiff)
Post by: zone117x on February 22, 2014, 07:56:18 PM

Open source: https://github.com/zone117x/node-stratum (https://github.com/zone117x/node-stratum)

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 port :)

This project does not do any payment processing. For a full featured portal that uses this module, see NOMP (Node Open Mining Portal) (https://github.com/zone117x/node-open-mining-portal). It handles payments, website front-end, database layer, mutli-coin/pool support, auto-switching miners between coins/pools, etc.. The portal also has an MPOS compatibility mode so that the it can function as a drop-in-replacement for python-stratum-mining (https://github.com/Crypto-Expert/stratum-mining/).

Features

Daemon RPC interface
Stratum TCP socket server
Block template / job manager
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 deamon that hasn't finished syncing to the network it shows the blockchain download progress and initializes once synced
Supports algorithms:
- SHA256 (Bitcoin, Freicoin, Peercoin/PPCoin, Terracoin, etc..)
- Scrypt (Litecoin, Dogecoin, Feathercoin, etc..)
- Scrypt-Jane (YaCoin, CopperBars, Pennies, Tickets, etc..)
- Scrypt-N (YaCoin, CopperBars, Pennies, Tickets, etc..)
- Quark (Quarkcoin [QRK])
- X11 (Darkcoin [DRK])

Example usage:

Create the configuration for your coin:

Code:

var myCoin = {
    "name": "Dogecoin",
    "symbol": "DOGE",
    "algorithm": "scrypt", //or "sha256", "scrypt-jane", "scrypt-n", "quark", "x11"
    "txMessages": false, //or true (not required, defaults to false)
};

If you are using the `scrypt-jane` algorithm there are additional configurations:

Code:

var myCoin = {
    "name": "Freecoin",
    "symbol": "FEC",
    "algorithm": "scrypt-jane",
    "chainStartTime": 1375801200, //defaults to 1367991200 (YACoin) if not used
    "nMin": 6, //defaults to 4 if not used
    "nMax": 32 //defaults to 30 if not used
};

If you are using the `scrypt-n` algorithm there is an additional configuration:

Code:

var myCoin = {
    "name": "Execoin",
    "symbol": "EXE",
    "algorithm": "scrypt-n",
    /* This defaults to Vertcoin's timetable if not used. It is required for scrypt-n coins that have
       modified their N-factor timetable to be different than Vertcoin's. */
    "timeTable": {
        "2048": 1390959880,
        "4096": 1438295269,
        "8192": 1485630658,

        "131072": 1674972214,
        "262144": 1722307603
    }
};

Create and start new pool with configuration options and authentication function

Code:

var Stratum = require('stratum-pool');

var pool = Stratum.createPool({

       detects those and disconnects them. */
    "connectionTimeout": 600, //Remove workers that haven't been in contact for this many seconds

    },

It seems that this don't work properly on x11 hash algo...
The workers cannot connect to stratum

Post by: zone117x on February 27, 2014, 04:06:26 AM

Can you give me some more detail? If it was a problem with the x11 hashing then you would be seeing low-difficulty shares most likely. Workers not being able to connect sounds like you just have a configuration problem.

Is there any live site currently running this module to watch it for testing purposes?

clevermining.com is in the process of integrating it into their system - not sure where they are at on that. It may or may not be running live on there at this point. Other than that, people have implied that they have been running it live but have not disclosed their pool to me.
The project is still fairly new - but in time I expect to add a list to the README of pools running it live :)

Tried this, however after your address is validated, it goes trough base58.decode. A few steps inside that you will eventually use the bignum function toString(base);
Now in here when running the .tostring(base) function the whole thing stops without an error. Any ideas?

Hi Tersken,
You need to provide much more information if you want help debugging. Open an issue on github and provide as many details as you can - especially your configuration and error stack trace.

created stratum.js as in your example

when starting

Sorry for the delayed reply.. Be sure to read the setup/require instructions in the readme. One of the commands is

Code:

npm update

Which fetches all modules/dependencies. :)

Hello ,

I have some difficult`s setting up NOMP module.
I have configured everything noticed in README but what is happening:
Connection is established between miner and back-end.Subscribe and authorize messages are sent by miner, and miner receive job . Miner start solving the job and... then nothing. Any idea?

Please help me, I'm a newbie in pool configuration, I want to add node stratum for MPOS but still have some questiions:

1.

Code:

Create the configuration for your coin:

Code:

Create and start new pool with configuration options and authentication function

Code:

Listen to pool events

What is their name and where to put them?
2. Where to run this command?

Code:

pool.start();

3. I add successfully NOMP to MPOS but when mining, pool shows my hash rate very low, where am I wrong?

Thanks for your help.

So, I keep getting an error while trying to install this stratum server code on Ubuntu. I've tried several systems, and updating redis and python as described in the readme, but the error never changes or improves.

I get the following a little ways through running "npm update"....

npm http 304 https://registry.npmjs.org/bignum/0.7.0

Hy,

i will install node-stratum-pool but... how?

Iam a node newbie. But iam a php, c# and java (jquery) programmer.
But i will save time.

so i had install node on my centOS Server and had made npm update. All ok. No errors on install.

So now i have the pool here... where i must place the config.js or config.json?
Where is the including in the code?

Must i place all https://github.com/zone117x/node-stratum-pool install infos in the config.js?

Where must i place the config? /lib/ ? or root?

node stratum.js to start? or must i make a start.js file with pool.start(); ?

Have anyone a step by step instruction ?

THX

Best Regards

I am trying to understand how to use NOMP to multi-mine using a Base58Check compatible pubkey and a custom profit switcher algo. In my case, I am working from a simple implementation of being able to manually switch the auto-switch pool from a web service. I've looked at the bitcoin code and wiki so understand the mechanics of key creation-- now I am wondering if someone can point me towards a handy utility to help generate WIF keys from a common key to import into an arbitrary wallet. So I don't have to write one. Not wanting to reinvent the wheel ( I was doing that already before I found NOMP <3 ) and I figure I'm overlooking a key piece of information to do this easily.

Thanks.

Hi zone117x!

I've successfully installed nomp in mpos compatibility mode as replacement for python-stratum-mining. I am using yacoin config file.
All seems to be OK! The shares are accepted.

When the block was found it accepted by wallet successfully. But nomp gives the error in console: "We thought a block was found but it was rejected by the daemon"

Code:

2014-07-13 18:29:06 [Pool]      [yacoin] (Thread 1) We thought a block was found but it was rejected by the daemon, share data: {"job":"387","ip":"192.168.1.101","port":3333,"worker":"ya.R9270X","height":629143,"blockReward":58760000,"difficulty":1,"shareDiff":"510.48249361","blockDiff":388.841603072,"blockDiffActual":0.005933252,"blockHash":"fe1b703bf84eae45499dc7a186279fc6bd5dcb82591537739303f283884fce06"}

Why is the block hash so weird? (not filled with leading zeroes)

So info about block doesn't stored in mysql base. And MPOS doesn't see any blocks found.

Can you make tutorial config stratum ?

I have a question - I'm running a guncoin pool now which is scrypt, but they're switching to neo-scrypt?

will this products support neo-scrypt and if so what changes to I need to make. I installed the stratum from git source about 10 week ago

thanks

I have installed nomp + MPOS, it's working and accepting shares and blocks are being solved but it's not displaying in the list of solved blocks neither in the block Explorer. There are transactions in the central wallet of solved blocks.
What could be the problem?
