[ANN] Grox (GROX) | Fair CPU solo mining | RandomX | 1-min blocks

Why Grox

Remember solo mining on your own PC and actually finding blocks? Grox brings that back.
It is a private coin built on the Monero codebase with its own RandomX variant, so it runs on ordinary CPUs and existing Monero hashrate cannot be pointed at it.
No pools needed, no rigs, no farms: install the wallet, press Start mining, and your computer competes for every block on its own.

The network is live and young: blocks every minute, a handful of miners, real rewards for every CPU that joins now.

Start mining in 3 steps

Windows
1. Download GroxWallet-Setup-1.2.2-win-x64.exe from the latest release (a portable .zip is there too).
2. Open Grox Wallet and create a wallet. Write your 25 words on paper.
3. Press Start mining. Wallet, node and miner run in one window.

Linux (Ubuntu 22.04 / 24.04, or WSL)

Code:

curl -fsSL https://raw.githubusercontent.com/ahafarag/grox-coin/main/install.sh | bash
~/grox/start.sh     # then open http://localhost:8790

Command line

Code:

~/grox/bin/groxd --start-mining <your G... address> --mining-threads 4

Every release is built in public by GitHub Actions from the repository code and ships with a SHA256 checksum. The installer checks it for you.

Network upgrade at block 12,000: run v1.2.0 or newer (latest is 1.2.2). Older versions stop following the network at that block.

Premine and dev fund: full transparency

Block 2 paid the 5% premine (1,050,000 GROX) to the developer. Every block pays 5% of its reward to the dev fund. Both are consensus rules checked by every node; see src/cryptonote_core/grox_dev_fund_address.cpp.
Community reserve: 100,000 GROX moved from the premine to the public dev fund wallet for bounties and contests (XMRig support, ARM builds, translations, tools). Transaction, block 4,211.
From block 12,000 the 5% dev fund goes to this dedicated wallet. Its view key is public, so anyone can audit every coin it receives (a view key can only see, never spend):
