What is XMR-STAK ?

XMR-Stak - Cryptonight All-in-One Mining Software

XMR-STAK is the only program that supports mining with CPU, NVIDIA GPUs and AMD GPUs. Also it is available for Windows, Linux and MacOS. XMR-Stak is a universal stratum pool miner to mine crypto currencies like Monero, Electroneum, BLOC and basically any coins that are powered by cryptonight algorithm.

XMR Stak is well optimized and it is known to significantly generate more hashrates than any other miners. Here in this beginners guide we’ll be showing you how to use XMR-STAK and start mining BLOC.



  • Mining BLOC with XMR-stak
  • support all common backends (CPU/x86, AMD-GPU and NVIDIA-GPU)
  • support all common OS (Linux, Windows and macOS)
  • supports algorithm cryptonight for Monero (XMR) and cryptonight-light (AEON)
  • easy to use
  • guided start (no need to edit a config file for the first start)
  • auto-configuration for each backend
  • open source software (GPLv3)
  • TLS support
  • HTML statistics
  • JSON API for monitoring


Choose your mining pool

You can find a complete list of the BLOC mining pools available on the BLOC MINING section of our website. We suggest you to select the nearest mining pool following your location for the best mining experience and results.

BLOC Configuration

  • currency: cryptonight_haven


HTML and JSON API report configuration

To configure the reports you need to edit the httpd_port variable. Then enable wifi on your phone and navigate to [miner ip address]:[httpd_port] in your phone browser. If you want to use the data in scripts, you can get the JSON version of the data at url [miner ip address]:[httpd_port]/api.json

This is how it looks :

Default Developer Donation

By default, the XMR-STAK will donate 2% of the hashpower (2 minutes in 100 minutes) to XMR-stak developers pool. If you want to change that, edit donate-level.hpp before you build the binaries. We strongly recommend to leave this donation fee at least 1% to help the XMRIG developers by providing regular updates.
