How to Mine C64 Chain (C64) in 2026

Updated June 2026 · Beginner-friendly · CPU (x86-64) mining guide

C64 Chain (ticker C64) is a community proof-of-work chain with a retro-computing identity, mined on the RandomWOW algorithm — a member of the RandomX family. That single fact tells you almost everything you need: this is CPU mining. No GPU farm, no ASIC, just the processor you may already own, an open-source miner, and a pool. This guide walks through exactly how to set it up and what determines whether it pays.

What is C64 Chain and how does mining work?

C64 Chain secures its network with RandomWOW, a tuned variant of RandomX — the algorithm class purpose-built to favor general-purpose CPUs. RandomX-family algorithms execute randomized programs that exercise the CPU's integer, floating-point, and memory subsystems, which makes specialized hardware pointless and keeps mining open to anyone with a desktop.

What decides your hashrate is mostly cache and memory: CPUs with large L3 caches (modern AMD Ryzen, especially the high-core-count parts) lead the field, and enabling huge pages in your operating system typically adds a double-digit percentage to throughput. Power draw is a desktop CPU's normal load wattage, so the economics hinge on cheap electricity and the coin's market price.

Mining software: XMRig is the standard open-source miner — select the RandomWOW variant with -a rx/wow. SRBMiner-Multi also supports RandomX-family algorithms on CPU.

How to mine C64 Chain: step by step

1. 1. Check your CPU

   Any modern x86-64 processor works, but large L3 cache wins: recent AMD Ryzen desktop chips are the reference hardware for RandomX-family mining. You'll also want at least 4 GB of free RAM and, ideally, dual-channel memory.

2. 2. Create a C64 wallet

   Generate a C64 Chain wallet address using the project's official wallet — this is the address the pool pays out to, and on most pools it doubles as your login. Back up your keys or seed offline before mining to it.

3. 3. Download XMRig and pick a pool

   Grab XMRig from its official GitHub releases (build from source if you want the last few percent). Choose a C64 pool with a low fee and a reachable payout threshold, and note its stratum host and port.

4. 4. Configure and start mining

   Run XMRig with -a rx/wow, -o pool:port, and -u your-wallet-address (add a worker name after a dot). Confirm the miner reports huge pages as available and shares as accepted; then check your address on the pool dashboard.

5. 5. Enable huge pages and tune

   If XMRig reports huge pages unavailable, enable them (vm.nr_hugepages on Linux, Lock Pages in Memory on Windows) — it's the single biggest free speedup. Then tune thread count: leaving 1–2 cores free often improves system stability without hurting hashrate much.

How to check your C64 Chain mining profit

Profit is revenue minus electricity, and both move daily. To get a number you can trust:

• Set your real power rate. The same hardware can be solidly green at $0.10/kWh and red at $0.25/kWh. Our electricity cost guide shows how much it swings the result.
• Use live numbers. Price, difficulty, and network hashrate all drift. Track them on the live C64 Chain mining page before and after you commit hardware.
• Compare against alternatives. The same hardware could mine another coin — or in the case of GPUs, earn from AI rental. See GPU mining vs. AI rental and the rig leaderboard.

Is mining C64 Chain worth it? The honest take

• Zero special hardware. You mine with a CPU you probably already own — the cheapest possible way to try proof-of-work mining.
• Young chain, young market. C64 is a small community coin; liquidity and price are volatile, so treat any USD projection as a sketch.
• Efficiency tuning is free yield. Huge pages, thread tuning, and RAM timing do more for RandomWOW hashrate than overclocking.
• Desktop-friendly. A tuned miner can run in the background at reduced threads — useful for testing the waters before committing.
