rx/pcoin support (unofficial build)

xmrigCC 3.4.10-dev with one added algorithm, rx/pcoin, for mining PCoin (PCN).

This is not an official xmrigCC release. The change is submitted upstream as Bendr0id/xmrigCC#435 and has not been reviewed or merged. It is not endorsed by the xmrigCC maintainer. If you would rather not run a binary from a stranger's fork — a reasonable position — build it from the add-rx-pcoin branch yourself, or wait for upstream.

It is also built differently from upstream's own binaries: gcc 13.3 on Ubuntu 24.04, CPU backend only, with OpenCL, CUDA and the CC client/server compiled out.

Usage

./xmrigMiner -o pool.pc.am:3333 -u YOUR_pc1q_ADDRESS -a rx/pcoin -t 4

Your payout address is the login — no registration, no password, and no wallet on the mining machine. It must be a v0 bech32 pc1q… address; a taproot pc1p… is refused by the pool.

Verified before publishing

• xmrigCC's own RandomX, keyed PCoin/RandomX/v1, reproduces mainnet block 3238's hash exactly
• PCoin's reference validator agrees with the chain on 100 mainnet blocks — and rejects all 100 when one nonce bit is flipped
• this binary had a share accepted by the live pool

You probably don't need this

The PCoin node has a CPU miner built in, and that is the supported path: https://github.com/pars5555/pcoin/releases — including a Windows build. This exists for people already running xmrig who would rather not run a second miner.

Honest expectations

PCN is not traded on any exchange. No orderbook, no way to sell it — treat it as worth zero dollars until a real market exists. Mining is a share of a fixed ~7,700 PCN/day emission, so earnings fall as others join. If you want money, mine something else.

No Windows build here: cross-compiling from Linux fails because the prebuilt xmrig-deps are UCRT-linked and Ubuntu ships no UCRT mingw compiler. Windows users are better served by the official PCoin zip above, or by building this branch on Windows with MSVC.
