# go-cryptonote-pool

High performance CryptoNote mining stratum written in Golang.

**Stratum feature list:**

* Concurrent shares processing
* AES-NI enabled share validation code with fallback to slow implementation provided by linking with [**Monero**](https://github.com/monero-project/monero) libraries
* Integrated NewRelic performance monitoring plugin

### Installation

Dependencies:

  * go-1.6
  * Everything required to build monero
  * Monero *v0.10.0*

#### Mac OS X

Install required packages:

    brew update && brew install go
    export GOPATH=~/go
    go get github.com/yvasiyarov/gorelic

Download and compile [Monero](https://github.com/monero-project/monero) *v0.9.4*.

Now clone stratum repo and compile it:

    git clone https://github.com/sammy007/go-cryptonote-pool.git
    cmake .
    make

Notice that for share validation stratum requires monero source tree where .a libs already compiled. By default stratum will use <code>../monero</code> directory. You can override this behavior by passing <code>MONERO_DIR</code> env variable:

    MONERO_DIR=/path/to/monero cmake .
    make

Build stratum:

    go build -o pool main.go

#### Linux

I would recommend you to use Ubuntu 16.04 LTS.

Install required packages:

    sudo apt-get install golang
    export GOPATH=~/go
    go get github.com/yvasiyarov/gorelic

In order to successfully link with monero libs, recompile monero with:

    cmake .
    CXXFLAGS="-fPIC" CFLAGS="-fPIC" make

Build CGO extensions:

    MONERO_DIR=/opt/src/monero cmake .
    make

Build stratum:

    go build -o pool main.go

#### Running Stratum

    ./pool config.json

### Configuration

Configuration is self-describing, just copy *config.example.json* to *config.json* and run stratum with path to config file as 1st argument.

```javascript

            }
        ]
    },

    // Monero daemon connection options
    "daemon": {
        "host": "127.0.0.1",
        // Monero RPC port, default is 18081
        "port": 18081,
        "timeout": "10s"
    }
}
```

### Private Pool Guidelines

For personal private pool you can use [DigitalOcean](https://www.digitalocean.com/?refcode=2a6767e6285f) droplet. With recent blockchain-db merged into Monero it's ok to run it even on 5 USD plan. You will receive 10 USD free credit there.
