# DRG-XMRig

**DRG-XMRig** is the official [DragonX](https://dragonx.is) CPU miner — a fork of
[XMRig](https://github.com/xmrig/xmrig) that mines DragonX's dual-hash
(RandomX + double-SHA256) proof of work.

**Repository:** https://git.dragonx.is/DragonX/drg-xmrig

## What's different

DragonX block validity is `SHA256D(header + RandomX(header)) <= target`: RandomX
produces the solution, and the **double-SHA256** of `header + solution` is the
difficulty-bearing hash.

DRG-XMRig filters **every** hash on that double-SHA256 pow-hash (not on the RandomX
hash), uniformly in both solo and pool mode. A block is therefore simply a share
that clears a harder target, which means:

- the pool receives **every** block candidate — no under-submission gap, and
- the reported hashrate is block-relevant (it matches the network metric).

It mines the `rx/dragonx` algorithm (aliases: `rx/hush`, `dragonx`) using DragonX's
customized RandomX parameters.

The exact wire protocol (job format, 32-byte nonce / extranonce handling, submit
format, pow-hash construction) is documented in [PROTOCOL.md](PROTOCOL.md). A
DragonX pool that scores shares on the double-SHA256 pow-hash is required.

Based on XMRig v6.25.

## Mining backends
- **CPU** (x86/x64, ARMv7/ARMv8, RISC-V)

## Build
```
./build.sh --linux-release      # Linux x86_64 static release
./build.sh --win-release        # Windows x86_64 (MinGW cross-compile)
./build.sh --macos-release      # macOS release for the host arch (Intel or Apple Silicon)
```
Linux/Windows dependencies are built by `scripts/build_deps.sh` on first run.
The macOS build uses Homebrew dependencies — install them once with
`brew install libuv hwloc openssl@3`. libuv/hwloc/OpenSSL are linked statically,
so the resulting binary runs on stock macOS without Homebrew.

## Usage
```
./xmrig -o <pool-host>:<port> -u <YOUR_DRGX_ADDRESS> -a rx/dragonx
```
The preferred way to configure the miner is the JSON config file (`config.json`).
