Latest release:

https://github.com/VextaProject/Vexta-CPU-Miner/releases/latest

Prebuilt binaries are available for:

• Windows x64
• Linux x64

Features

• Vexta RandomX mining
• RandomX full-memory mode
• Windows x64 and Linux x64 support
• Automatic CPU thread selection based on physical cores
• Manual CPU thread override with -t
• Startup diagnostics for CPU, cores, AES, Huge Pages, and RandomX library
• Local hashrate display
• 5 / 15 / 60 minute average hashrate
• Accepted / rejected share statistics
• Automatic RandomX seed changes
• Daemon-confirmed BLOCK FOUND notifications when supported by the pool

Usage

Windows

vexta-cpuminer.exe -o stratum+tcp://POOL:PORT -u WALLET.WORKER -p x -t THREADS

Example:

vexta-cpuminer.exe -o stratum+tcp://pool.example.com:9335 -u YOUR_VEXTA_ADDRESS.worker1 -p x -t 4

Linux

./vexta-cpuminer -o stratum+tcp://POOL:PORT -u WALLET.WORKER -p x -t THREADS

Example:

./vexta-cpuminer -o stratum+tcp://pool.example.com:9335 -u YOUR_VEXTA_ADDRESS.worker1 -p x -t 4

Parameters

Parameter	Description
-o	Stratum pool address
-u	Vexta wallet address, optionally followed by .worker
-p	Pool password, normally x
-t	Number of CPU mining threads (optional; auto-detects physical cores when omitted)

Requirements

• 64-bit Windows or Linux
• Approximately 2+ GB available RAM for the RandomX dataset
• AES-capable CPU recommended

RandomX full-memory mode is enabled.

On startup, the miner reports detected CPU information, physical and logical CPU counts, AES support, Huge Pages status, RandomX library status, and the selected mining thread count.

If -t is omitted, the miner automatically uses the detected physical core count.

Building from Source

Requirements

• .NET 6 SDK
• Git
• CMake
• C/C++ build tools
• RandomX v2.0.1

Clone the miner:

git clone https://github.com/VextaProject/Vexta-CPU-Miner.git
cd Vexta-CPU-Miner

Linux x64

dotnet restore

dotnet publish Vexta.CpuMiner.csproj \
  -c Release \
  -r linux-x64 \
  --self-contained true \
  -p:PublishSingleFile=true \
  -p:IncludeNativeLibrariesForSelfExtract=true

Windows x64

dotnet restore

dotnet publish Vexta.CpuMiner.csproj \
  -c Release \
  -r win-x64 \
  --self-contained true \
  -p:PublishSingleFile=true \
  -p:IncludeNativeLibrariesForSelfExtract=true

RandomX Native Library

The miner uses the official RandomX implementation:

https://github.com/tevador/RandomX

Tested version: v2.0.1

Linux example

git clone --branch v2.0.1 https://github.com/tevador/RandomX.git
cd RandomX

cmake -S . -B build -DCMAKE_BUILD_TYPE=Release
cmake --build build -j$(nproc)

Place librandomx.so next to vexta-cpuminer.

Windows

Build RandomX as a 64-bit DLL and place librandomx.dll next to vexta-cpuminer.exe.

The official release packages already include the required native RandomX library.

Pool Compatibility

This miner is specifically designed for Vexta RandomX.

It uses a Bitcoin-style 80-byte block header.

Supported Stratum methods:

• mining.subscribe
• mining.authorize
• mining.set_difficulty
• mining.notify
• mining.submit

RandomX Seed

Vexta RandomX pools must provide the RandomX seed as the 10th parameter of mining.notify.

The miner uses this seed to initialise and update the RandomX dataset.

BLOCK FOUND Notification

The miner supports the optional Vexta Stratum extension:

mining.block_found

Example:

{
  "id": null,
  "method": "mining.block_found",
  "params": [
    12345,
    "BLOCK_HASH"
  ]
}

This notification should only be sent after the daemon has accepted the block.

Pools that do not implement mining.block_found can still be used normally. The miner will simply not display the confirmed BLOCK FOUND message.
