ZCash Stratum proxy (Increase earning up to 10%)

PistoleDev · October 4, 2017, 7:31pm

Hi guys.
We released today the first Open-Source ZCash Stratum proxy, which streamlines mining on multi-miners infrastructures/farms (also helpful for small/personal mining farms).
This software is provides AS-IS without dev-fee and without any warranties of any kind.

Source code (nodejs) and instructions are available on Github:

Zecproxy v1.0.0

This proxy has been tested with flypool and nanopool successfully.
Tested with EWBF’s Zcash CUDA miner. 0.3.4b

Main Features

Zcash stratum proxy
Additional up to 10-20% increase of earning compared to standard pools
Pool failover system
Only one connection to the pool
Workers get new jobs immediately
Submit of shares without network delay, it’s like solo-mining but with benefits of professional pool
Central Wallet configuration, miners doesn’t need wallet as username
Bypasse worker_id for detailed statistic and per rig monitoring - not supported on flypool yet / working on nanopool
PM2 support

Hi guys,
Today, we fixed an important bug on zecproxy (it became unstable after a peer disconnection…)
Please update the code to version 1.0.1
Enjoy

PistoleDev · October 11, 2017, 1:07pm

Hi guys
We just releaded the version 1.0.4.

Change log :

Stability improvements
Reconnection bugfixes
False share rejection fix
Authentication logging
SSL encrypted connection support

Enjoy !

can you explain the advantages of using a stratum proxy to a noob like me please?
why earnings increase?

thanks for your work,

deke997 · October 12, 2017, 2:28am

Awesome! I will be using this for sure! @PistoleDev I may need a little bit of help setting this up. Can you help me?

anon92308673 · October 12, 2017, 7:43am

Interesting, I wrote a quick Dockerfile to test this.

FROM node:alpine
RUN apk add --no-cache -U git && \
    git clone --depth 1 https://github.com/BScrk/zecproxy.git && \
    npm install zecproxy && \
    apk del git

EXPOSE 8000
WORKDIR /zecproxy
COPY config.json .
CMD ["node", "proxy.js"]

Hi @n0g1291
First of all, find here a small scema of how a stratum proxy works :

  Pool A < ---+                         +------------- > Rig 1 / Worker 1
 (Active)     |                         |
              |                         +------------- > Rig 2 / Worker 2
              |                         |
  Pool B < ---+--- > StratumProxy < ----+------------- > Rig 3 / Worker 3
(FailOver)                              |
                                        +------------- > Rig 4 / Worker 4

There are several main advantages :

First of all, the stratum json-rpc communication protocol is much more efficient than the HTTP “get work” version in term of latency & bandwidth usage. Even if modern miners support the tcp/ssl stratum protocol as well, using a stratum proxy allow you to aggregate communications with the pool in one unique point.
The Stratum proxy is like a “personal” pool, the work submission and new work reception are centralized by the proxy and sent directly to the miners through the local network instead of maintaining N open connections through the web (this is particularly effective with several rigs/workers).
From the pool point of view, having more and more miners/workers to deal with increases dramatically bandwidth/ressources usage. By using proxies we all contribute to pools workload reduction and so increase community efficiency
By aggregating your workers hashrates through an unique “virtual miner” (which stratum proxy does), you increase by design the number of shares you validate per Hash/sol. In addition, the proxy always has the latest block informations (target / work) from the mining pool so it can quicky provide it to miners according to their needs (new one / reconnected / etc…)
With your own stratum proxy you have an unique point of monitoring . For now you can see if your rigs are alive or not by “simply” scanning the output log, and we are working on an better monitoring way (console UI + Json api…), this will coming soon !

So basically, if you have more than 1 worker, the proxy usage will optimize you mining setup and earnings.

Would it be possible to round robin load balance between multiple pools?

To remove date output, feel free to replace ./lib/stratum_logger.js file by the following :

var config = require('../config.json')
var date = require('date-and-time');
const chalk = require('chalk');

// - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
var log = function (args) {  console.log(chalk.cyan(' INFO') + " # " + args); } 
// - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
var warn = function (args) {  console.log(chalk.yellow(' WARN') + " # " +args); } 
// - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
var err = function (args) { console.log(chalk.red(' ERROR') + " # " +args); } 
// - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
var dbg = function () {
  if(config.debug){
    return Function.prototype.bind.call(console.log, console);
  }
  return ()=>{};
} ();
// ----------------------------------------------------------------------------
module.exports = {

One downside I noticed is when using Claymore miner, its dev fee is 2% if connected using SSL and 2.5% when not connected using SSL (this man-in-the-middle proxy).

anon92308673 · October 12, 2017, 7:23pm

On zhash.pro each worker got recognized but on luckpool.org only the proxy shows up.

PistoleDev · October 12, 2017, 7:55pm

Yes, it’s the same with Flypool. They don’t implement multiple workers identification through an unique tcp/ssl connection
Nanopool / zhash does…

CoinDuck87 · October 12, 2017, 11:33pm

How to run this in windows? I’ve got java node now what?

kajzer · October 15, 2017, 9:13pm

Hi, does it works on Windows?

anon92308673 · October 16, 2017, 1:34am

Switched from running this on a Raspberry Pi 2 to Raspberry Pi Zero. Total OS memory usage is 36MB and the load average is 0.1 with 19 peers.

BarbieAction · October 16, 2017, 9:10am

Anyone tested this with ethOS and Ewbf miner?
