Description

This is a Stratum Proxy for Zcash using JSON-RPC.

Originally developed by the Cryptense team.

Working with Dwarfpool and Nanopool. Also tried on Miningspeed on Zclassic / BitcoinZ / ZenCash coins. Some issues with flypool, better not use with this pool.

Successfully tested with EWBF's Zcash CUDA miner. 0.3.4b and dstm's ZCash Nvidia Miner v0.5 (Linux) with several GPUs Rigs.

WARNING This work is still in development. Please report any broken features or issues.

Features

• Additional up to 10-20% increase of earning compared to standard pools
• Zcash stratum proxy
• 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
• SSL / TCP protocols support

How it Works

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

Todo

• Logfile setup
• ASCII UI
• Watchdog system (alive / gpu failure)
• Hashrate computation

Installation and Start

• git clone https://github.com/BScrk/zecproxy.git
• cd zec_stratum
• npm install
• npm start

The proxy will automatically listen on port 8000 for miners.

Configuration

• all configs in file config.json to change settings.

{
  "wallet": "<Your wallet>",
  "password" : "<Pool password or just 'x'>",
  "port": <Proxy port>,
  "proxy_name" : "<Proxy default name>" (shown on the pool if enable_worker_id set to false),
  "enable_worker_id": true|false (send worker name to the pool or not), 
  "pool" : { "host" : "<HOST>"  , "port" : <PORT>, "ssl" : true|false },
  "pool_failover_enabled": true|false,
  "pool_failover" : [  { "host" : "<HOST>"  , "port" : <PORT>, "ssl" : true|false },
                       { "host" : "<HOST>"  , "port" : <PORT>, "ssl" : true|false },
                       { "host" : "<HOST>"  , "port" : <PORT>, "ssl" : true|false }],
  "restart_delay": <delay before restarting the proxy on error>,
  "on_rejected_share": {
                      "strategy" : "<On Rejected Share strategy>" (continue / kill / restart),
                      "threshold" : <number of rejected shares before applying strategy>
                    },
  "debug" : true|false
}

On Rejected Share strategies :

• continue : ignore and continue
• restart : Restart the proxy (without pm2)
• kill : Kill the process (hard restart using pm2)

Miners command line

EWBF's Zcash CUDA miner

./miner --server <PROXY_ADDRSS> --user <RIG_NAME> --pass <PASS> --port <PROXY_PORT>

exemple : ./miner --server 192.168.0.10 --user miner_1 --pass "x" --port 8000 --solver 0

dstm's ZCASH Cuda Miner

./miner --server <PROXY_ADDRSS> --user <RIG_NAME> --pass <PASS> --port <PROXY_PORT>

exemple : ./miner --server $192.168.0.10 --port 8000 --user miner_1 --pass "x"

Docker

The project is now dockerized for more convenience :)
