SAFEX CASH MINING

CPU solo mining

Download and build safex core blockchain client:

$ sudo apt update && sudo apt install build-essential cmake pkg-config \
    libboost-all-dev libssl-dev libzmq3-dev libunbound-dev libminiupnpc-dev \
    libunwind8-dev liblzma-dev libreadline6-dev libldns-dev libexpat1-dev \
    doxygen graphviz libpcsclite-dev
$ git clone https://github.com/safex/safexcore.git --recursive
$ cd safexcore
$ make -j<CPUNUM>

Start safex blockchain node, wait for it to sync:

$ /path/to/directory/safexcore/build/release/bin/safexd

Start mining to the target address:

start_mining <addr> [<threads>]

GPU solo mining

Ubuntu 18.04

Download and build safex core blockchain client and shared libraries:

$ git clone https://github.com/safex/safexcore.git --recursive
$ cd safexcore
$ cmake -D CMAKE_BUILD_TYPE=Release -D BUILD_SHARED_LIBS=ON .
$ make

Sync Safex blockchain

$ /path/to/directory/safexcore/bin/safexd

Build local Startum proxy:

$ sudo apt-get install golang
$ git clone https://github.com/sammy007/monero-stratum.git
$ cd monero-stratum
$ MONERO_DIR=/path/to/directory/safexcore cmake .
$ make
$ cp -v ./config.example.json ./build/bin/config.json

Setup configuration for monero-startum to target local Safex node. Also set address that will receive block reward.

"address": "Safex5zN1S4dFF6LP2zzxy3BtFsKJZ2Q8jLpqNEr46ENhVLtxasf6rahe3hpjWXiVFWNdues5z22x8U69AC7WZqZDgu3rnQjJmQ2K",
...
"upstream": [
		{
			"name": "Mainnet",
			"host": "127.0.0.1",
			"port": 17402,
			"timeout": "10s"
		}

With local safexd node running and synced, run monero-startum

$ cd /path/to/monero-stratum/build/bin
$ ./monero-stratum ./config.json

NVidia Graphic Cards

Install latest NVidia driver if it is not installed:

$ sudo add-apt-repository ppa:graphics-drivers/ppa
$ sudo apt update
$ sudo apt-get install nvidia-driver-396

Install Cuda Toolkit

$ sudo apt-get install nvidia-cuda-toolkit

Download and build xmrig-nvidia

$ sudo apt-get install git build-essential cmake libuv1-dev libmicrohttpd-dev gcc-6 g++-6
$ git clone https://github.com/xmrig/xmrig-nvidia.git
$ cd xmrig-nvidia
$ mkdir build
$ cd build
$ cmake -D CMAKE_C_COMPILER=gcc-6 -D CMAKE_CXX_COMPILER=g++-6 ..
$ make
$ cp -v ./src/config.json ./build/

Configure xmrig-nvidia by editing xmrig-nvidia/build/config.json

"algo": "cryptonight/1",
"donate-level": 1,
...
"pools": [
        {
            "url": "127.0.0.1:1111",
            "user": "anything.rigname",
            "pass": "x",
            "rig-id": null,
            "nicehash": false,
            "keepalive": true,
            "variant": 1
        }
    ],

Start mining

$ cd /path/to/xmrig-nvidia/build
$ ./xmrig-nvidia

Note: xmrig-nvidia should be customized to support Safex Cash donation, currently that is not the case and donation will be wasted. xmrig-nvidia successfull mining printout:
